Product overview
There are two basic types of glassbreak sensors: acoustic and shock. Acoustic sensors listen
for the unique sound of glass breaking, while shock sensors feel the wave generated by glass
breaking.
Acoustic sensors
Acoustic glassbreak sensors are an important part of an effective perimeter detection system.
It is very important to choose the right sensor for a particular application or environment.
GE offers you a variety of choices for virtually any glassbreak application.
ShatterPro 3, the premier technology. ShatterPro 3 acoustic glassbreak sensors give
you a potent combination of range, reliability, flexibility, and ease of use. They offer a 25 ft.
(7.6 m) radius range for extended glassbreak detection. Using patented pattern recognition
technology, the sensor is designed to eliminate common false alarms and improve detection
of framed glass breaks. It does this by listening for the unique sound of glass breaking at
numerous points across the entire frequency spectrum, not just at one or two points.
ShatterPro Plus, 24 hours a day. The ShatterPro Plus is an acoustic glassbreak sensor
combined with a passive infrared motion sensor (PIR). The sensor can detect break-ins
through glass while eliminating occupant-generated false alarms.

Acoustic sensor testing with the GT-2 tester
To verify sensor range and operation for 2000 model acoustic sensors, use the GT-2 tester
and do the following:
1. Remove the cover from the glassbreak sensor.
2. To put the sensor in test mode, press the test button on the sensor two times. The
sensor LEDs will blink slowly. (See the sensor installation instructions for test
button location).
3. For a low frequency test, tap the wall or ceiling near the sensor. The sensor LEDs
should stay lit during the alarm event.
4. For a high frequency test, press the test button on the sensor two times. The sensor
LEDs should blink rapidly. Place the cover on the sensor. Place the GT-2 tester
behind the curtains of the window to be protected (see Figure 2 on page 6) and press
the test mode switch on the tester (Figure 3). The sensor LEDs should remain lit
during the alarm event.
5. The sensor will time out of test mode in 15 minutes.

Shock sensors
Breaking glass produces specific shock frequencies that travel through glass and window
frames. When shock sensors feel the wave generated by breaking glass, they signal an alarm.
These sensors mount directly on the glass or the frame and give you a product virtually
immune to false alarms. Shock sensors can operate on windows with heavy drapes or
shutters and they help prevent break-in attempts by providing a visual deterrent to intruders.
Most GE shock sensors are solid-state, with no mechanical part to wear out or fail. We
incorporate a piezo transducer specifically tuned to the sh ock frequency of glass breaking,
providing both excellent detection and false alarm immunity . Use Table 2 to choose the right
shock sensor for a particular application or environment.

When using glassbreak sensors, follow these guidelines:
• Glass must be in good repair (not cracked) and securely mounted in its frame.
• A bullet or BB going through the glass will probably not be detected. The
glassbreak incident must leave a fist-sized hole before a sensor is expected to detect
the incident.
• Sensors are designed to work on glass that is a minimum of 1 square foot
(0.3 x 0.3 m).
• Acoustic glassbreak sensors are designed to detect breaks in framed windows from
the outside in.

Prewire installation
Application. New construction applications offer the opportunity to prewire an acoustic
glassbreak sensor, creating an attractive, unobtrusive installation. The 5812NT and 2100
sensors, installed on a single-gang box, are especially appropriate for prewire installations.
Installation. Open the sensor and screw the back of the sensor onto the single-gang box as
shown in Figure 4.

Inconspicuous installations
Application. Sometimes customers want their security system to be as inconspicuous as
possible. This is especially true in most residential, office foyers, executive offices, and
upscale retail store installations. The 5820A Recessed ShatterPro II sensor is the least
obtrusive acoustic glassbreak sensor available. When installed, the sensor is little larger than
a quarter and is rarely noticed. Another option is to hide a 5600 ShatterPoint sensor behind
curtains or blinds.
Installation. The 5820A (Figure 5) can protect an entire room. Sensor range is 25 ft.
(7.6 m) to the bottom of the glass in a 360-degree pattern. Mount the sensor on the ceiling,
the opposite wall, or an adjoining wall (Figure 6 on page 12). To install the sensor, do the
following:
1. Drill a 1 in. (2.5 cm) diameter hole through the drywall or ceiling tile in the desired
location.
2. Insert the 1 in. (2.5 cm) sleeve into the hole and insert the sensor into the sleeve. Use
the trim ring, if necessary, to cover any irregularities in the drywall hole.

The 5600 is a shorter range sensor that protects up to 10 ft. (3.1 m) of glass. For a hidden
appearance, mount the sensor on the window frame behind curtains or blinds (Figure 7 on
page 12). To protect windows that open, use a sensor with a built-in magnetic contact.

Bathroom windows
Application. Bathrooms are challenging environments for glassbreak sensors. Humidity
can be very high and bathrooms are acoustically live rooms. These attributes produce a
greater potential for false alarms when acoustic sensors are used. Shock sensors are a better
choice and have fewer problems than acoustic sensors in high humidity environments such
as bathrooms.
Installation. For best false alarm immunity in bathrooms, use the hermetically-sealed
GS600 shock sensor with 12 ft. (4 m) of range mounted on the glass (Figure 8). To protect
windows that open, use the frame-mounted GS611 shock sensor with built-in magnetic
contact. Both sensors work with the GS614 analyzer.

Skylights
Application. Skylights can be a vulnerable entry point to many homes and businesses. To
protect skylights made of Plexiglas or other types of plastic, use a shock sensor. To protect
glass skylights, use an acoustic glassbreak sensor.
Installation. To protect plastic skylights, mount a 5150 shock sensor in a corner of the
skylight 1 in. (2.5 cm) in from the frame (Figure 9). If more than 3.5 ft. (1.1 m) of range is
required, mount two sensors in opposite corners.
The plastic material in the skylight will absorb much of the shock energy from a break and
the range of a shock sensor on plastic is typically 50 percent less than the range on glass. For
example, a shock sensor with a 7 ft. (2.1 m) range on glass would generally have a 3.5 ft.
(1.1 m) range on a plastic skylight. See Shock sensor testing on page 8.
T o protect glass skylights, mount a 5600 sensor on the ceiling or on any wall within range of
the skylight or use a GS600 sensor mounted on the frame. To protect vented skylights, use
the GS611 with built-in magnetic contact.

Windows with curtains and blinds
Application. Many homes and offices have windows with curtains or blinds. The 5150
shock sensor can protect windows regardless of the type of window covering present. With
proper placement, acoustic sensors can also protect windows with blinds and light drapes.
Installation. Mount shock sensors in the corner of the glass, 1 in. (2.5 cm) from the frame.
Shock sensors are not affected by curtains or blinds. See Shock sensor testing on page 8.
You can also mount a 5600 sensor on the window frame behind curtains or blinds to protect
one or more windows (Figure 10). The sensor will protect a 10 ft. (3.1 m) area, although the
range may be reduced if the window coverings are touching the glass. For windows that
open, use a sensor with a built-in magnetic contact.
For a larger range on windows with venetian or vertical blinds, mount a 5812NT
ShatterPro 3 or a 5820A Recessed ShatterPro II on the ceiling (Figure 11 on page 16),
adjoining wall, or a wall opposite the glass you want to protect. See Acoustic sensor testing
with the 5709C on page 6.

Single window with wireless sensor
Application. A wireless-compatible shock sensor can be used for economical protection of
rooms with a single window. For glass doors or windows that open, use a wireless
compatible sensor with a built-in magnetic contact.
Installation. Mount the 5150 shock sensor on the glass, 1 in. (2.5 cm) in from the corner.
Range is a 7 ft. (2.1 m) radius out from the sensor.
The 564503 frame-mounted shock sensor can protect two fixed windows in the same
window opening (Figure 12). Range for the sensor is up to 10 ft. (3.1 m). Frame mounting
affects the sensor range, so it is essential to test the sensor (see Shock sensor testing on
page 8). The sensor includes a built-in magnetic contact to protect windows that open.
These sensors must be connected to a transmitter.
Note: The 564503 Wireless ShatterPoint shares the battery of the transmitter. Its current draw of up to
15 microamps may reduce transmitter battery life by up to 50 percent. Since other devices are
likely to need battery replacement before the sensor, this is rarely a problem.

Multiple windows with wireless sensors
Application. To economically protect multiple windows use one transmitter and a 584503
Wireless ShatterPro acoustic sensor. The sensor combines excellent false ala r m immunity
and consistent detection with wireless compatibility and has a coverage radius of 20 ft. (6.1
m) if mounted on a ceiling. A single sensor can typically protect an entire room.
Installation. To hide the transmitter and provide an integrated look, mount the transmitter
inside the back box of the 584503 sensor. The transmitter can also be mounted next to the
sensor on the bracket (included with the sensor).
Note: The sensor shares the transmitter battery, which may reduce battery life by up to 50 percent.
Since other devices are likely to need battery replacement before the sensor, this is rarely a
problem.
Position the 584503 sensor a minimum of 4 ft. (1.2 m) and a maximum of 20 ft. (6.1 m) from
the glass (Figure 13). See Acoustic sensor testing with the 5709C on page 6

French doors and small windows
Application. Older homes often have windows with small panes and French doors. Small
windows have unique properties when they break. The sound o utput may be low since there
is not much glass to break and the glass may pop out of the window frame when hit instead
of breaking. Detection in both cases can be difficult.
Modern French doors are usually two large pan es of glass with false dividers between them.
The dividers have little effect from a detection standpoint you do not need to take any
special precautions.

For more consistent detection, use a GS600 frame-mounted shock sensor. Often several
sensors will be needed to protect a frame of multiple windows. Make sure you test the sensor
(see Shock sensor testing on page 8) and use additional sensors as needed.
Minimum glass size for glassbreak sensors is 1 square foot (0.3 x 0.3 m).

Glass doors and windows that open
Application. Running wires from the glass to the frame can make glass door protection a
challenge. A shock or acoustic sensor with a built-in magnetic contact can make both
glassbreak and forced-open protection possible.
Installation. To protect glass doors and windows that open, use a 5150C or GS611 shock
sensor, or a 5620 shock/acoustic sensor. The 5150C sensor mounts on a corner of the frame
and ships with a 3 ft. (0.9 m) coil cord that reaches to a termination on the frame (Figure 15).
The 5620 and GS611 sensors have built-in magnetic contacts and mount on the frame.
Mount the sensor’s magnet on the door or movable window and mount the sensor on the
frame as close as possible to the magnet. See Shock sensor testing on page 8.

Insulated glass
Application. Many modern buildings use windows that contain two panes of glass divided
by an air space for added insulation. You can protect this insulated glass with shock and
acoustic glassbreak sensors. As long as the inside pane of the glass breaks, the sensor will
detect the break. It is possible to break the outside pane of glass without setting off an alarm.
Installation. Installation for insulated windows is the same as for other windows. Mount
5150 or GS600 shock sensors in the corner of the glass or GS611 shock sensors on the
frame. Mount 5600, 5620 or 5812NT acoustic sensors so that the protected glass is within
the sensor’s range (Figure 16).

Windows with film
Application. Film is applied to windows for a variety of reasons. In sunny climates some
commercial windows have a tinting film attached to the glass. Some commercial windows
have a plastic film attached to the glass to prevent shattering from impact or bullets. This
armor-coated glass can be found in bank drive-up windows, in retail stores, and in other
vulnerable buildings.
Installation. Tinted film does not affect shock sensors. To mount shock sensors on the
glass, cut away the film where the sensor will be placed so that the mounting tape is affixed
to the glass itself and not to the film (Figure 17).
Armor-coated glass may reduce shock sensor range. Thoroughly test shock s ensors (see
Shock sensor testing on page 8) to see if additional sensors are needed.
Recommended products. Any GE shock sensor, as long as the installation guidelines
are followed.

Glassbreak/shock sensors
Chapter 1
Thick glass
Application. Some installations may have glass thicker than the 0.25 in. (0.6 cm)
maximum thickness rating of acoustic and shock sensors. Since thick glass absorbs much of
the shock energy from a break, it is more of a challenge for glassbreak detection. Shock
sensors can be used on thick glass if they are thoroughly tested (multiple sensors may be
needed). ShatterPro sensors are not designed to protect thick glass and should not be used
for this application.
Installation. Use the 5150 or GS600 shock sensor and mount the sensor on the glass
approximately 1 in. (2.5 cm) in from the corner (Figure 18). See Shock sensor testing on
page 8 and add multiple sensors as needed.

Large rooms
Application. Most large rooms have several windows, often widely spaced from each
other. The most economical way to protect large rooms with multiple windows is with a
single, long-range acoustic sensor. However, be careful to match sensor range to room size.
If the sensor range extends beyond the room boundaries it is vulnerable to false alarms.
Installation. Use a 5812NT ShatterPro 3 or a 5802A Recessed ShatterPro II to protect
large glass areas and up to four walls of glass. To protect glass on more than one wall, mount
the sensor on the ceiling (Figure 19). Make sure that all protected glass is within the sensor’s
coverage pattern. The distance from the bottom of the window to the sensor must be no more
than the sensor’s maximum range.
To protect one wall of glass, mount the sensor on the opposite wall (if all protected glass is
within the sensor’s range). See Acoustic sensor testing with the 5709C on page 6.
Recommended products. 5812NT, 5820A, 2000

Glassbreak/shock sensors
Chapter 1
Small rooms
Application. False alarms are more likely in small, acoustically live rooms such as small
kitchens, glass entry airlocks, stairwells, small glass offices, and utility rooms. Shock
sensors offer the best false alarm immunity and are the most economical if there is only one
window to protect. If an acoustic sensor is preferred, you must match the range of the sensor
with the size of the protected room and glass to minimize false alarms.
Installation. In small room applications, follow these guidelines:
• To protect a single window in a small room, use a 5150 shock sensor mounted on
the glass or a 5414 or GS600 sensor mounted on the frame.
• For windows that open, use a 5415A or GS611 sensor with a built-in magnetic
contact (Figure 20). See Shock sensor testing on page 8.
• To protect multiple windows in a small room, use a 5600 ShatterPoint.
• Do not install an acoustic sensor with a large range in a small room. For example, a
sensor with 25 ft. (7.5 m) diameter range in a 10 ft. (3.1 m) room increases the risk
of false alarms. See Acoustic sensor testing with the 5709C on page 6.

Occupied areas
Application. Occupied areas can be protected either on a perimeter loop or on a 24-hour
loop. On a perimeter loop, sensors are armed when the magnetic contacts on doors are
armed. On a 24-hour loop, sensors are armed continuo usly.
Installation. For 24-hour loop protection, mount a 5150 shock senso r on the glass 1 in.
(2.5 cm) in from the corner, or frame-mount a 5600 shock sensor with the correct sensi tivity
setting (see Shock sensor testing on page 8). The 5885 ShatterPro Plus acoustic sensor can
also be used for 24-hour loop applications.
For perimeter loop protection, use a 5600 for glass areas smaller than 10 ft. (3.1 m). For
larger glass areas, use a 5812NT, 2000, or a 5820A recessed acoustic sensor. See Acoustic
sensor testing with the 5709C on page 6.

Rooms with cleaning crews
Application. Often the perimeter loop of the security system is armed when the cleaning
crews are in a building. If acoustic sensors are armed, they will be listening to all sounds,
including those made by night cleaning crews. Acoustic sensors are most likely to false
alarm to multiple sounds. The cleaning crews produce a combination of sounds from
vacuums, floor polishers, and clattering garbage cans, all of which combine to cause false
alarms for some sensors in some applications.
Installation. The 5150, 5600, and GS600 shock sensors provide the best false alarm
immunity for a building when it is occupied. However, multiple shock sensors can be
economically impractical for applications with large numbers of windows an d may not be an
option in applications where appearance is important.When multiple shock sensors will not
work for your application, use the 5885 ShatterPro Plus acoustic sensor that combines a
passive infrared sensor with a glassbreak sensor (Figure 22). When an occupant enters the
field of view of the PIR, the glassbreak sensor is disabled for 70 seconds. This prevents false
alarms due to loud noises such as vacuums or floor buffers. The 5885 makes 24-hour
acoustic applications possible.

Storefront windows
Application. Merchants often want glassbreak protection on their front windows, in order
to have the alarm sound as soon as the glass breaks. While this does not prevent smash and
grab losses, it helps prevent burglars from actually entering the building.
Installation. To protect storefront windows, 5150, 5620, or GS600 shock sensors are the
best choice. The sensors mount on the glass or frame and are visible from the outside to
deter burglars before the glass is broken. Shock sensors are also less likely to be set off by
street noise or rolling metal shutters than acoustic sensors. However, multiple shock sensors
may be required to cover the same glass area that one acoustic sensor can protect
(Figure 23). See Shock sensor testing on page 8.
To successfully use acoustic sensors to protect storefront glass, store personnel must be
trained to keep the sensor’s line-of-sight clear. If the sensor’s vision is blocked by store
displays or furniture, the sensor is unlikely to detect a break-in. In stores without window
displays, mount a ShatterPro 3 or 5820A ShatterPro II on the ceiling. In stores with window
displays, Mount a 5600 ShatterPoint directly above the glass. See Acoustic sensor testing
with the 5709C on page 6.

Roll-up metal shutters
Application. Retail shops in high-risk areas will often have roll-up metal shutters to
protect glass windows at night. The clanging and banging sounds of these shutters can cause
acoustic sensors to have false alarms. False alarms can also be caused by people rattling the
shutters by or other sources of vibration.
Installation. GS600 or 5150 shock sensors provide the best false alarm immunity on
windows with roll-up shutters. The sensors mount on the glass (Figure 24) and are easily
visible from the outside to deter break-ins. See Shock sensor testing on page 8.
If acoustic sensors are preferred, use the 5812, 2000, or 5820A sensors. Mount the sensor
away from the street and roll-up shutters and within specified range limits. See Acoustic

Glass display and jewelry cases
Application. Museum curators and retailers with glass display and jewelry cases often
want glassbreak sensors inside their cases. Both shock and acoustic sensors can be used in
this application.
Acoustic sensors sealed within a glass display case are extremely live and are vulnerable to
false alarms if the case is accidently struck by keys or other metal objects. For this reason,
acoustic sensors are only appropriate for applications where the sensor will only be armed
when the premises are not occupied. For occupied or 24-hour protection, use shock sensors.
Installation. The 5150 and GS600 shock sensors mount directly on the glass and are the
best choice if only one piece of glass needs to be protected. For protecting multiple glass
walls in the case, use one or more frame-mounted 5600 sensors. Use a 5620 sensor with
built-in magnetic contact to detect a forced opening. T o prevent sensor tampering, you must
place the sensors inside the case (Figure 18). See Shock sensor testing on page 8 and use
multiple sensors as needed.
If using multiple shock sensors is not a viable solution, use a single acoustic sensor with a
limited range. We do not recommend the ShatterPro sensors for this application.

Metal enclosures
Application. The 5402 and 5422 shock sensors eliminate the need for costly lined boxes or
placement of security system controls in a vault for UL mercantile applications. To meet UL
requirements, a tamper switch is required.
Installation. To protect metal enclosures, use the self-powered 5402 or 4-wire 5422 shock
sensor. Mount the sensor on the side wall on or near the hinge. If the hinge runs the length of
the side, center the sensor vertically (Figure 26). If the enclosure has multiple hinges, mount
the sensor next to the hinge nearest the middle of the enclosure.
To mount the sensor, do the following:
1. Peel back the paper from one side of the adhesive tape pad and press it onto the back
of the sensor. The tape pad must be flat against the plastic case.
2. Use a 50/50 solution of isopropyl alcohol/water to clean the mounting area. Dry the
mounting area, then peel the backing paper from the tape pad and press the sensor
against the metal. The tape will fully adhere within 24 hours.
31
3. W ire the sensor (if applicable) to the loop according to wiring instructions.
4. To test the sensor, use the metal shaft of a medium-size screwdriver to lightly scrape
back and forth against the edge of the metal enclosure farthest from the sensor
(Figure 26). If the sensor does not respond, a second sensor may be required.

Jewelry store safes
Application. Jewelry store safes present several protection challenges. The safes hold high
value merchandise, but are generally small in size. The stores are located in public locations,
such as shopping malls and strip malls, where employee turnover can be high. The
DV1201A sensor can protect safes from internal (employee) and external threats and lower
store owner’s loss risk.
Installation. Since most attacks against safes are aimed at the door and the locking
mechanism, mount one sensor on the body of the safe and another inside the door close to
the hinges (Figure 28). Use flexible cable kit DV1219A together with the junction box
DV1228A. Also add a magnetic contact (2707A or similar) on the door. Cable outlets are
normally provided in new safes, if not, we recommend you mount the sensors on the outside
of the safe.

ATM and night deposit boxes
Application. ATM (automatic teller machines) and night deposit boxes are located in high
activity public areas and involve cash. There is also environmental vibration from normal
operations. These factors combine to make protection a challenge.
The DV1221A sensor ignores environmental vibrations while ensuring actual attacks are
detected. The sensor sounds an alarm before the intruder gains access to the contents of the
machine.
Installation. For ATMs, the best locations for sensors are the door and as close to the
dispenser opening as possible. These locations are the most likely points of attack.
To protect night deposit boxes, use the same sensors. Attenuate the chute and the landing
place with rubber insulating material to reduce the noise created by the falling cash boxes
when deposited (Figure 29).

Product overview
Passive infrared (PIR) motion sensor technology provides one of the most reliable and cost
effective methods for protecting spaces in homes, offices, or industrial facilities. PIR motion
sensors sense temperature contrasts between a relatively stable background and hotter or
colder objects moving across their fields of view. The sensors emit no energy of their own,
they merely see infrared images.
RCR sensors
The PrecisionLine dual technology sensors combine range-controlled radar (RCR)
technology with a passive infrared (PIR) system. This combination increases false alarm
immunity by allowing them to sense human-sized objects within a specified range. Both the
RCR and the PIR system must be triggered to set off an alarm, unless in stealth mode (radar
only). An internal jumper allows you to disable the PIR and use the radar-only stealth mode
to detect intruders faster. The stealth mode can also be used for covert installations (mounted
behind walls or drop-tile ceilings).

Installation guidelines
Use the following installation guidelines for motion sensors:
• Position the sensor so that any intruder must cross the sensor’s field of view. To
trigger an alarm, an intruder must cross both the positive and negative elements of
one zone.
• Test the sensor in the direction of likely intruder motion and walk test monthly. See
Walk test on page 42.
• Locate the sensor so that valuables are well within its coverage pattern.
• Terminate each protection zone on a solid object such as a wall or floor.
• Use an industrial sensor in locations where a standard sensor may be affected by
water, steam, or oil.
• Do not aim sensors at sources of rapid heating or cooling. These sources include
forced air ducts, space heaters, fireplaces, direct sunlight, strong white lights, and
mirrors that can reflect strong light.
• Do not obstruct the sensor’s field of view.
• Seal optics when possible.
Chapter 2
Motion sensors
Outdoor installation guidelines
T est your appl ication over a 24-hour perio d and use the follo wing guidelines when installing
outdoor motion sensors:
Sunlight. Avoid direct sunlight on the plastic lens (even with UV stable plastics).
Temperature. Make sure the temperature range is within sensor specifications. For
example, the 6187CTX sensor is rated to work from -40 to 120°F (-40 to 50°C). Be
aware of temperatures in excess of the sensor ’s specifications.
Humidity/rain/fog. If conduit is used, run conduit out the side or bottom of the sensor
to keep conduit condensation from draining into the sensor housing. Make sure the
conduit openings and the mounting holes on the sensor are well sealed.
Birds and animals. Depending on the size, speed, and proximity to the sensor, warmblooded animals can trigger an alarm. The larger the animal, the farther away it can be
detected. Avoid directing the sensor towards bushes or branches where birds can perch.
You can mount two sensors in parallel to require alarm verification.
Trees and bushes. Tree branches or bushes can cause an alarm when the wind moves
them, and can block detection. Keep branches and bushes at least 30 ft. (9.15 m) from
the sensor.

Walk test
To ensure proper operation, always walk test the sensor location. To walk test, do the
following:
1. Mount the sensor in the desired location.
1. Walk throughout the intended coverage pattern.
2. Verify the sensor alarms (see the specific sensor installation instructions).
Most sensors walk test more accurately if you wait 10 seconds between tripping the sensor
and walking again. This allows the sensor to stabilize between trips.
Prewiring
Prewiring allows you to work with the builder in the planning stage to determine optimum
locations for sensors. It will also allow you to avoid many of the hazards inherent in postconstruction installations such as drilling through the electrical cables, plumbing, and ductwork hidden in existing walls.
When wiring after construction, compromises are usually the norm. Existing walls, lighting
fixtures, air conditioning ducts, and other obstacles often determine sensor and control panel
locations. Compromises such as these can leave blind spots in security installations.
Motion sensors are available that will fit into standard outlet boxes just like a light switch.
The flush-mount SureShot (6255FM) sensor fits into a standard single-gang box, remodel
box, or rough-in plate in two easy steps.You simply connect the wires to the proper terminals
on the back of the unit, then screw the unit into an outlet box like you would a switch.
Chapter 2
Motion sensors
False alarm reduction
Many GE motion sensors allow you to select one or two zone detection (Figure 30). Each
zone is made up of two fields of view, one positive and one negative. With one zone
selected, an alarm will be indicated when an intruder moves across one positive and one
negative field. With two zones selected, an intruder must cross the positive and negative
fields of two zones before an alarm is indicated. We recommend two-zone detection (except
when using long-range and curtain lenses) to reduce the chance of false alarms. See the
sensor’s installation instructions for details on setting the zone detection.

Masking areas on motion sensors
Most motion sensors include masks to modify the coverage pattern to fit specific
applications. Coverage curtains should be masked to avoid sources of false alarms such as
heaters, air conditioners, and windows. Available masks include:
• Plastic masks to cover large areas (Figure 31 on page 44)
• Adhesive labels used on mirror curtains (Figure 32 on page 44)
• Undercrawl window masks to improve false alarm immunity in the presence of
objects within 5 ft. (1.5 m) and directly under the sensor (Figure 33 on page 44)

Motion sensors
Loop supervision
If a resistor is placed at the end of a protection zone (at the last unit in the line), that zone
becomes a supervised loop. A small amount of current can always be applied to that loop,
allowing it to watch the wiring at all times. You can then program the system to give a
warning light or audible alarm if it is tampered with during daytime hours. Supervising the
loop is a security technique used to prevent internal tampering.
Terminal blocks with shared terminals
The SureShot and some older Sharpshooter sensors have SPDT (single-po le double-throw)
contacts in which the normally open (NO) and one of the tamper (TAMP) terminals are
shared. When wiring a tamper switch in series with the alarm output in the normally closed
configuration, be sure to wire the terminals as shown in the correct diagram in Figure 34. If
the jumper wire is placed from the normally closed (NC) terminal to the NO terminal, as
shown in the incorrect diagram, no alarm will sound. When wiring a tamper switch in series
with the normally closed alarm loop, place the jumper or EOL device between the COM and
T/NO terminals.

• Lights (see Hallways and lobby lighting activation on page 58 and on page 80)
• Recorded messages (see Museums on page 55)
Swivel brackets
The 6083-N swivel bracket can be used with the 6187CTX outdoor PIR sensor, the 6198
nonincendive PIR sensor, and the 6197 intrinsically safe PIR sensor in areas where
mounting is difficult.
You can mount the bracket on a flat wall or in a corner (Figure 35). The maximum adjusting
angle for a flat-wall mount is 22.5 degrees. Mount the bracket with the small self-tapping
screws that ship with it.

Pets
Application. Because PIR sensors are sensitive to moving, heat-radiating sources, they can
be triggered by animals as well as humans. To avoid this false alarm hazard, do one of the
following:
• Use a sensor with pet immunity
• Use a sensor with a pet alley lens
• Mount a sensor upside down to create a pet alley
Installation using a sensor with pet immunity. The introduction of the
PrecisionLine RCR-PET with its dual technology RCR (range-controlled radar) and PIR,
has virtually eliminated the need to create a pet alley associated with nominal motion
sensors. The RCR-PET provides excellent pet immunity for animals up to 80 pounds, and
detects only objects within a very precise range of user settings. Table 5 gives examples of
pet immunity limits for RCR-PET sensors. The table is not accurate for other sensors.
The AP100PI, PI6000, and AP950PI sensors also have pet immunity. See specific sensor
installation instructions for details.

Discreet appearance
Application. When adding a security system to an existing residence, the appearance of the
system is often very important to the homeowner. The homeowner is concerned with sensor
placement, wiring and control panel location, and holes drilled through existing walls.
The 6351 DesignLine sensor combines an attractive, unobtrusive design with an easy-tomount snap-on bracket. It can be mounted in a corner within 1/8 in. (0.3 cm) of the ceiling.
This sensor can save you installation time and cost, and has a standard 90-degree lens that
provides entire room coverage with one sensor.
Installation. To install the sensor, do the following:
1. Choose a mounting location close to the ceiling in the corner adjacent to the room’s
entrance (Figure 39) to get the best sensor line of sight. Pull wiring through the
ceiling where possible for a faster, easier installation.
2. Using the foam spacer, mount the bracket to the wall. Connect the wires to the
sensor terminal block and snap the cover in place.
51
3. Most rooms need only one-zone sensitivity, but if the room is subject to temperature
fluctuations or other instability, adjust the sensor for two-zone sensitivity.
4. Test the sensor (see Walk test on page 42).

Flush mount
Application. Flush-mount motion sensors make protection no more intrusive in a room
than an electrical outlet or switch. Flush-mount PIR sensors are most often used in prewired
security installations, but can also be used in retrofit installations.
Installation. The 6255FM flush mount SureShot (Figure 40) fits into a standard, plastic
single-gang box. If the security system is to be prewired, mount a single-gang box for each
sensor as planned with the builder. Sensor wires can be easily run through walls and routed
to the control panel. Due to noise problems, do not run PIR sensor wires beside AC wires.
To install the sensor, do the following:
1. Mount the box in the ceiling. For retrofit installations, take care to cut a hole in the
wall just large enough to fit the single-gang remodel box.
2. Run wires through the box to the sensor terminal block.
3. Screw the sensor into the single-gang box as you would an electrical outlet and walk
test the sensor to ensure correct operation. See Walk test on page 42.

Ceiling mount
Application. Mounting a sensor in the ceiling is a good way to hide wiring in single-level
homes. Running wires in an attic allows you to easily avoid water pipes, duct work, and high
voltage wiring. It also provides complete coverage of rooms with obstructions such as halfwalls and shelving that can block wall mounted sensor coverage.
Installation. For flush mount installation, install a standard plastic single-g ang outlet box
in the ceiling (Figure 41). Use a remodel box for homes where construction is already
complete. Always test the installation (see Walk test on page 42).
If you use the 6255 or 6255FM sensors, ensure the ceiling is less than 12 ft. (3.7 m) high. If
you use the AP669 sensor, ensure the ceiling is less than 16 ft. (4.9 m) high.

Antimasking
Application. In high-risk applications, you may need to guard against an intruder disabling
a motion sensor. The intruder could gain access to the sensor when the installation is
disarmed and spray the lens (Figure 42) or cover the lens with a transparent piece of glass
that blocks the sensor window. The intruder could then return when the installati on is armed
and know the sensor would not detect his presence.
The AP950AM antimasking motion sensors have built-in technology that looks for a
masking tamper and notifies the system of the problem.
Installation. Use a AP950AM motion sensor in this application and install the sensor as
appropriate to the installation environment. You do not need to do anything to enable the
antimasking feature.

Storefront windows
Application. A curtain motion sensor, such as the AP450 or AP475, provides a cost-
effective and secure means of intrusion detection through large windows and doors that are
typical of a storefront or car showroom.
Installation. To mount the sensor, do the following:
1. Mount the sensor 3 ft. (0.9 m) from the window. This avoids any possibility that one
half of the curtain is looking at the window, while the other half is not (a potential
cause of instability). If this is not possible, angle the sensor slightly inwards.
2. Make sure the sensor is set to standard sensitivity and the appropriate range.
3. Install the appropriate mirror masks. Figure 45 shows the left side of the pattern
masked out (always mask out curtains that are directed at the windows), while the
right side is active to protect the inside of the store.
4. Test the sensor (see Walk test on page 42).

Application. Use motion sensors to protect long narrow areas such as corridors or hallways
(see Long corridors or aisles on page 69 for commercial applications). You can also use a
sensor with a separate relay and power supply to activate lighting controls in hallways and
lobbies.
When choosing a sensor for this application, consider the length of the hallway, range and
appearance of the sensor, and if pets will be a factor.
Installation. Mount a sensor with a single-spot or vertical barrier lens at the opposite end
of a hallway or lobby from its entrance (Figure 46). Anyone entering the hallway from the
entrance or from side doors will be detected.

Request-to-exit door control
Application. Hospitals, schools, commercial offices, warehouses, and a variety of other
access control applications require request-to-exit door control. Assuring that automatic
door opening devices prevent intrusion while permitting authorized ingress/egress can be a
challenge and often requires multiple sensors. The RCR-REX sensor meets this challenge.
The sensor’s range controlled radar (RCR) technology was originally intended to prevent
air-to-air collisions. Now GE has applied this technology to the RCR-REX for false alarm
immune motion detection.
Installation. Mount the sensor directly to a door mullion, the ceiling, or the wall just above
the door (Figure 48). The RCR-REX provides aiming and range control capabilities that
make it easy to adjust the distance for the appropriate coverage. The sensor will detect
motion toward the door and activate an event flag in the access control panel. The event flag
will start a macro that will unlock the door and shunt the door switch for the programmed
time period or until the switch is closed (Figure 49 on page 61).

Request-to-exit roll-up door control
Application. Drive-through areas with roll-up doors such as shipping dock s, garages, and
car service centers, are good applications for request-to-exit door control using the RCRREX. Benefits include both security and economic advantages, such as heat conservation.
The sensor’s dual technology requires both heat from the car engine and vehicle motion
before the internal relay is triggered (Figure 50). You can use the 15 ft. (4.6 m) range of the
RCR-REX to signal an attendant with a bell or to automatically open the door. The sensor
can provide both local annunciation and an alarm with forced entry.
Installation. The RCR-REX is not designed for outdoor environments and is intended for
indoor use only. For pet or rodent immunity, adjust the radar curtain at a height from 1 to 2
ft. (0.3 to 0.6 m) above the floor. Adjust the internal turret for a maximum range of 7 ft. (2.1
m) when the device is mounted at 15 ft. (4.6 m).

Room perimeters
Application. Motion sensors can be sensitive to direct sunlight. In a room with multiple
windows, the windows can limit the choice of coverage patterns and mounting locations.
However, you can use four sensors to protect the entire perimeter.
Installation. Use a sensor in each corner (Figure 51). Mount the swivel bracket near a
corner and connect the back case of the sensor to the bracket. The outside coverage zone
should run parallel to, but not touch, the wall to be protected. With proper aiming you can
reduce the unprotected space near the wall.
Test the installation (see Walk test on page 42).

Multilevel homes
Application. In homes with a multilevel floor plan, you must take care to ensure complete
coverage. The most cost-effective way to obtain complete coverage is to mount a sensor
with a 360-degree lens on the wall or ceiling. A standard, wall-mounted 90-degree lens may
leave unprotected zones that an intruder can use to invade a home.
Installation. Mount the sensor on a wall that is adjacent to the room’s entrance to get the
best sensor line of sight (Figure 52). You can also mount the sensor in the ceiling to achieve
360-degree coverage of the room.
Test the installation (see Walk test on page 42).

Valuable equipment
Application. To protect valuable equipment, such as computers, TVs, and video
equipment, mount a sensor in the ceiling above the equipment (Figure 53) and use a very
narrow coverage pattern.
Installation. Use a 6255 SureShot or a 6255FM SureShot with a single spot mask in this
application. Verify that the sensor range is suitable for the application. Mount the sensor in
the ceiling directly above the equipment and test (see Walk test on page 42).
You can also use an RCR-A or RCR-C set at a range of 9 ft. (2.7). If you want to hide the
sensor above a drop-tile ceiling, you must use the sensor’s stealth mode. See RCR sensors on
page 36 and the sensor’s installation instructions.

Vacation homes and garages
Application. Garages and vacation homes often contain valuable objects and present some
protection challenges. They are not always temperature-regulated, and, in the case of
garages, there can be a risk of damage to sensors from accidental impac ts with balls and
tools. The 6187CTX operates from -40 to 120°F (-40 to 50°C) and is ideal for protecting
garages and vacation homes in cold climates. The RCR series sensors are a good solution in
installations where temperature extremes are not an issue.
Installation. Mount the sensor as indicated by the specific sensor’s installation
instructions. Use the swivel bracket included with the sensors to aim and adjust the sensor
(Figure 54), if needed, and test the sensor (see Walk test on page 42).

Indoor swimming pools
Application. Use 6187CTX or 618703 sensors to sound a local alarm upon unauthorized
entrance into indoor swimming areas either in homes or in hotels. The cast metal housing of
the 6187CTX sensor provides water resistance in humid indoor swimming environments.
Installation. Mount the sensor approximately 7 ft. (2.1 m) high on a wall adjacent to the
entrance door, pointing downward (Figure 55), or in the ceiling pointing toward the door.
Walk test the installation (see Walk test on page 42).
If conduit is used, run the conduit out the side or bottom of the sensor to keep conduit
condensation from draining into the sensor housing. Make sure conduit openings and

Large areas
Application. Large indoor areas such as factories, sports or concert halls, gymnasiums, and
warehouses, can require multiple sensors for adequate coverage. With an 80 ft. (24.4 m)
wide angle coverage pattern, a single AP633A can often do the job of several conventional
PIR sensors, saving material and labor costs. The coverage includes a complete 40 ft.
(12.2 m) curtain and a 200 ft. (60.9 m) long-range field of view (Figure 56) that can be
enabled when required. The combination of step focus mirror and microprocessor controlled
4D signal processing ensures excellent detection in all ranges and trouble-free performance
in these often difficult environments. If you need coverage of 90 ft. (27.4 m) or less, the
RCR-90 is also a good solution.
Installation. Mount the AP633A between 6 and 10 ft. (1.8 and 3.0 m) high. Select the
correct sensitivity for standard wide-angle detection. For fine adjustments, use the aiming
mechanism described in the installation instructions and walk test the installation (see Walk

Long corridors or aisles
Application. Supermarkets, factories, and schools frequently have long corridors or aisles
that need protection. The AP633 with a range of 200 ft. (60.9 m) provides the longest
coverage range of any PIR sensor available. The step focus mirror ensures that even at
maximum range, detection is crisp and consistent without oversensitivity at closer ranges. If
you need coverage of 90 ft. (27.4 m) or less, the RCR-90 is also a good solution.
Installation. Mount the AP633 (Figure 57) betw een 6 and 10 ft. (1.8 and 3.0 m) high.
Select the correct sensitivity for Curtain/Long range detection. Carry out fine adjustments
using the aiming screws and install masking devices as described in the installation
instructions. Be aware that a minor horizontal or vertical reorientation can result in a major
displacement of the field of view at 200 ft. (60.9 m). W alk test the installation (see Walk test
on page 42). If detection is not satisfactory at long range, check the vertical orientation. An
uneven wall can make the sensor aim slightly downward, reducing range.

Schools
Application. Protecting schools presents challenges to security system installers. Rooms
are typically larger than in other commercial environments (auditoriums, lecture halls,
gymnasiums), and hallways are longer. Vandalism is a concern and it may be necessary to
protect outdoor areas to prevent unwanted entry at certain times of the day or night.
Installation. Locate sensors high, near the corners of walls where they are least
conspicuous. For outdoor applications, mount the 6187CTX Industrial PIR with cast metal
housing out of reach of vandals, in areas where they will not be exposed to direct sunlight.
The 6187CTX is also ideal for areas that may be exposed to water, high humidity such as
school kitchens (Figure 58), or chemicals such as shops.
For larger areas and long hallways (see Long corridors or aisles on page 69), use the AP633.
It provides 80 ft. (24.4 m) wide angle, 40 ft. (12.2 m) curtain, and 200 ft. (60.9 m) long range
coverage patterns. If you need coverage of 90 ft. (27.4 m) or less, the RCR-90 is also a good
solution.

Motion sensors
Outdoor areas
Application. There are many applications for outdoor motion protection. Most stem from
the need to protect property that is at risk. Residential yards, parking lots (Figure 59),
outdoor shopping areas, outdoor garden shops, auto dealerships, aircraft hangers, perimeters
of military installations, and public utility installations are all ex ampl es of such applications.
The cast metal housing of the 6187CTX PIR sensor is specifically designed for outdoor
applications, and the sensor provides water resistance and reliable detection in temperatures
from -40 to 120°F (-4- to 50°C). The 60-639-95R-OD is also rated for outdoor applications.
Both sensors should be used in fenced applications for local alarm or camera activation only.
Installation. Mount the sensor approximately 7 ft. (2.1 m) high (Figure 59). Avoid direct
sunlight on the lens and keep away from branches that may impede sensor coverage pattern.
See Outdoor installation guidelines on page 41. Walk test the installation (see Walk test on
page 42).
If conduit is used, run the conduit out the side or bottom of the sensor to keep conduit
condensation from draining into the sensor housing. Make sure conduit openings and
mounting holes are well sealed.

Motion sensors
Drive-through pickup areas
Applications. Drive-through areas are used by stores and other businesses for parcel
pickups. A motion sensor with a long range lens can be used to signal the store attendant
with a bell and/or lights when a car pulls up at the pickup door. The long range lens provides
spot detection of automobiles and minimizes false alarms from people in the walkways next
to the drive-through lane. This configuration is designed for local annunciation, not alarm.
The sensor is responding to the heat of the car engine and upon initial startup some car
engines may not generate sufficient heat to trip the sensor.
Installation. Mount a 6187CTX sensor in the ceiling directly above the drive-through area
(Figure 61). Test the installation (see Walk test on page 42).

Vegetable gardens
Application. Use a 6187CTX or 618703 motion sensor to sound a local alarm when
animals enter a fenced vegetable garden. The cast metal housing of the 6187CTX sensor is
specifically designed for outdoor applications and provides water resistance and reliable
detection in temperatures from -40 to 120 °F (-40 to 50°C). Use a curtain lens and mount a
sensor on all four sides of a fenced garden to provide complete perimeter detection. If the
sensors are covered to protect them from rain, outdoor-rated 60-880-95R-OD and 60-880-95
sensors are also good options.
Installation. Mount one sensor approximately 7 ft. (2.1 m) high at each corner of the
garden (Figure 62). Avoid direct sunlight on the lens and keep away from branches that may
impede sensor coverage. See Outdoor installation guidelines on page 41.
If conduit is used, run the conduit out the side or bottom of the sensor to keep conduit
condensation from draining into the sensor housing. Make sure conduit openings and
mounting holes are well sealed.

CCTV camera activation
Application. Use a motion sensor to activate CCTV cameras that monitor outdoor parking
lots, auto dealerships, shopping areas, shipping areas, garden shops, aircraft hangars,
perimeters of military installations, and public utility installations. In this application, the
sensor does not directly activate a central station alarm. Rather, it alerts a guard station and/
or automatically starts a CCTV recording device. This prevents false alarms due to birds and
other animals that might enter the sensor’s coverage area.
Installation. Connect a 6187CTX or 60-639-95R-OD sensor to the local alarm switch in a
guard station or to a CCTV camera. Mount the sensor approximately 7 ft. (2.1 m) high
(Figure 64). Avoid direct sunlight on the lens and keep away from branches that may
impede the sensor coverage pattern. See Outdoor installation guidelines on page 41.
If conduit is used, run the conduit out the side or bottom of the sensor to keep conduit

Product overview
GE Security has earned its leadership position in the manufacture of magnetic contact
sensors by pioneering advances such as the use of multiple reads, wide gapping, and
numerous features that reduce false alarms. We have developed a range of innovative
designs to assure both greater sensitivity and complete reliability, even in the most
demanding environments. With over 400 models to choose from, we offer the most
comprehensive line of magnetic contacts and peripherals available.
Built for durability and dependability, GE magnetic contacts are conservatively rated at
10,000,000 cycles for closed loop (Form A), ensuring long life. UL rates SPDT (Form C) at
100,000 cycles. Every reed connection is hand soldered, and the switches in many models
are environmentally sealed in polyurethane. Each magnetic contact is tested before they
leave the factory.
Our world-class manufacturing standards and attention to detail virtually eliminate out-ofbox failures. You can install our magnetic contacts quickly and with confidence in their
reliability.
Many residential and commercial applications for magnetic contacts are similar. Residential
users, however, will typically be more concerned with appearance than commercial users.
Commercial considerations include specific issues such as how to protect valuables in
storefront windows or display cases, how to protect steel doors and windows, and how to
protect trucks at loading docks. Magnetic contacts are particularly suited for use on a
24-hour loop to protect occupied areas.

Control switching using DPDT switches
This information describes how to achieve dual switching with one magnetic contact and
one magnet (Figure 68). DPDT (double-pull, double-throw) magnetic contacts such as the
1087D, 1084D, 2507AD, or 2707AD may be used in place of two contacts or one contact
and a floor mat for an annunciator panel. Other applications include access control multiplex
systems, computer monitoring of doors, lighting control and safety systems. DPDT switches
are available in recessed, steel door, surface, and industrial outdoor models.
Note: Each switch is electrically and mechanically isolated from the other and may switch at a slightly
different point.

Mounting positions for recessed switches
Recessed contacts can be installed in a variety of positions to accommodate any application.
As shown in Figure 69, the switch and magnet can be mounted end-to-end within an
imaginary arc around the switch, or parallel to the switch. If using a wide-gap switch with a
bare magnet, the red end must be mounted away from the switch (wide-gap switches are
sensitive to the polarity of the magnet).
Gap distance will vary approximately 20% from the rated gap distance of the switch,
depending on the type of switch and the mounting position. It will be necessary for the
installer to experiment to determine if a given switch will work in a given position.
Note: Switch and magnet must not be mounted in a T configuration. In cases where a surface magnet
must be used with a recessed switch, use a surface-mount switch from the 1082 switch series.

Professional tips for reliable installation
To prevent switch damage as green lumber dries, twists, and contracts:
• Over-drill (loose fit) the mounting hole. Use RTV mounting compound (1905) to
hold the unit in place.
• As an alternate, use an adapter such as the 1908 model.
• Use model 1275 or 1275W wing fit models.
To protect loose-fitting doors from false alarms:
• Mount the switch and magnet toward the hinge side of the door.
• Use a wide-gap switch to assure trouble-free performance.
To protect steel doors:
• Use wide-gap switches for maximum tolerance.
• Use recessed switches that provide adequate insulation from steel, such as the 1078
or 1078C model.
Ohmmeter testing
T o verify switch operation with an ohmmeter, set the range to 200 Kohms. For a closed loop
(normally open) switch, the meter will read an open when the actuator is away. On a digital
meter this is typically displayed as OL. The meter will show resistance value when the
actuator is within sensing range. Metering at the switch you will see at or near 0 ohms when
the magnet is in proper alignment with the reed switch. In a typical residential setting you
will see a resistance value of 4 to 6 ohms when metering the switch and cable. If the circuit
includes an end-of-line (EOL) resistor, the meter will reflect the accumulated resistance of
the switch, cable, and resistor. You will see opposite readings when an open loop (normally
closed) switch is used.

Steel door and window test
This section covers the results of tests on GE magnetic contacts used on steel doors and
windows.
Test procedures. Each sample was selected at random from finished goods inventory.
Tests on each contact measured pull-in (make), and drop-out (break) distances prior to
mounting on a 6 in. (15.2 cm) wide, 16 in. (40.6 cm) long, and 0.5 in. (1.3 cm) thick steel
plate.
Each contact pull-in (make) gap distance was measured:
• With the contact and magnet attached directly to the 0.5 in. (1.3 cm) steel plate with
no spacers.
• With a single 0.125 in. (0.3 cm) spacer under both the contact and magnet. A 0.5 in.
(1.3 cm) spacer was used under both the magnet and contact in the 2505 test.
All measurements were recorded to the nearest 0.05 in. (fifty-thousandths of an inch).

Conclusions. Surface-mount contacts can be used in such applications as steel fire doors,
safes, file cabinets, truck doors, and roll-up garage doors. Allow a safety factor in
installation. We recommend installing the contact and magnet with no more separation than
approximately 50% of the pull-in distance. For instance, on the 1084TW measurements on
steel, a maximum separation of 0.5 in. (1.3 cm) to 0.6 in. (1.5 cm) should provide a reliable
system.
Steel door and window installation guidelines. Use the following installation
guidelines for steel door and window applications:
• The gap on steel is approximately half the distance achieved in the air.
• Space the switch and magnet approximately 25 percent of the rated gap in air for a
safety factor.
• Use a spacer whenever practical. If only one spacer is used, mount it under the
magnet.
• Applications on steel do not drain the magnet, but they do reduce the magnetic
field.

Voltage spike protection
When magnetic reed switches are wired in line with relay devices with coils, the reverse
voltage spike generated when current is removed from the relay can fuse the switch contacts
together.
As shown in Figure 70, when the contact is closed, current flows through the relay coil and
magnetizes the iron core. When the contact is opened, current from the power supply stops
and the magnetism of the relay iron drops to zero instantly. The collapsing magnetic field
draws voltage into the relay coil. Since the coil is open (open reed switch) and there is no
circuit loading to limit the voltage, spikes from the open relay can reach 500 volts or more,
causing arcing across the reed contacts. Most GE reeds arc between 150 and 200 volts, well
within this reverse voltage kick.
Repeated arcing roughens and pits the reed switch blades until they eventually stick together
mechanically . Tapping on the switch will cause the contacts to release (open). However, this
is only a temporary fix.

DC circuit solution. Voltage kicks or transients from DC circuits are easily controlled by
adding a diode across the relay coil, as shown in Figure 71. The diode has no effect on the
circuit when the current flows in the right direction. However, when current from the po w er
supply stops suddenly and the relay coil generates a reverse voltage, it shorts through the
diode. The stripe on the diode points toward the + voltage. The diode used should be a
1N4002, 1N4003, 1N4004, or equivalent.

AC circuit solution. In AC circuits, current flows through the relay coil in both directions.
Using a diode would simply short out half of every cycle. However, a bidirectional transient
suppressor diode can be used to clip off voltage spikes in either direction installed in parallel
with the switch, as shown in Figure 72. The transient suppressor diode must be selected to
fit the voltage used in the circuit. T o find the correct diode voltage rating, multiply the circuit
voltage times 1.414. For example, in a 24-volt circuit, a transient suppressor diode rated at
34 volts or more may be used (24 x 1.414 = 34).

Automatic garage doors with switch shunting
Application. Use relays to provide on and off alarm protection when an exit delay is part o f
the system and entrance and/or exit is via a door to the garage. The garage door must also
have an automatic opener that has a timed entrance light.
Installation. For installation, use two 110-volt AC SPST (single-pull, single-throw)
hermetically sealed relays (Figure 76 on page 95), and do the following:
1. Place the coil of Relay 1 across the AC line going to the motor which opens the
garage door.
2. Place the coil of Relay 2 across the AC line going to the light on the garage door
opener.
3. Place both sets of the 110-volt relay contacts in parallel and connect them together
across the garage door contact. Use a junction box to ease wiring.
User operation is as follows:
• Before leaving home, arm the alarm system and leave via the door leading to the
garage, which would normally be on the Exit/Entry delay loop.
• As you signal the garage door to rise, Relay 1 activates as the motor starts and
shunts the garage door contact, preventing an alarm.
• As the door rises, the light comes on and Relay 2 activates, also shunting the garage
door contact.
• Once the door is all the way open, the motor shuts off, causing Relay 1 to drop out.
However, the light remains on for a fixed period of time, so Relay 2 remains
activated, still shunting the garage door contact and preventing an alarm.
• Prior to the light going out (this should be timed), ex it the garage and signal the door
to lower.
• The motor starts, activating Relay 1 and shunting the garage door relay.
• The light, still on, restarts the timed cycle and Relay 2 remains activated.
• When the door is completely closed, Relay 1 drops out.
• After a fixed time, Relay 2 drops out and returns the loop to the garage door contact
and normal operations.
