General Description
System Sensor Model BEAM200A/BEAM200SA is a long range
projected beam smoke detector designed to provide open area
protection. It is to be used with ULC-listed compatible control
panels only. The detector consists of a transmitter/receiver unit
and a reflector. Smoke entering the area between the transmitter/
receiver and reflector causes a reduction in signal. When the
obscuration reaches alarm thresholds (chosen at the transmitter/
receiver unit), the detector generates an alarm signal. Complete
blockage of the beam causes a trouble signal. Slow changes in
obscuration due to a build up of dirt or dust on the lens of the
detector are compensated for by a microcontroller that continuously monitors the signal strength and periodically updates the
alarm and trouble thresholds. When the self-compensation
circuit reaches its limit, the detector generates a trouble signal,
indicating the need for service.
Special Applications
Due to the inherent capabilities of projected type beam
detectors they are often installed in locations where spottype detection is impractical. Projected type beam smoke
detectors are ideally suited for environmental conditions
that might include high ceilings, dusty and dirty environments, or environments that experience temperature
extremes. Often these conditions present special problems
for the installation of spot-type detectors and even greater
problems for their proper maintenance. Due to the inherent
flexibility of mounting locations and large coverage area of
projected type beam detectors often the conditions above
can be addressed or minimized.
Some examples of applications for beam detectors might
include freezers, aircraft hangars, cold storage warehouses,
shipping warehouses, enclosed parking facilities, sporting
arenas and stadiums, concert halls, barns, or stables. Some
of these environments might be considered to hostile for
spot-type smoke detectors. If the environment is considered to be hostile then the colder alarm threshold settings
should be used.
Three LEDs on the detector indicate the current status: a
red LED for alarm, a yellow LED for trouble, and a blinking
green LED for standby operation. Note: The panel controls
the status of the red and green LEDs. The local reset button is accessible by removing the outer paintable trim ring.
The yellow LED will blink in specific patterns to provide a
diagnostic aid when diagnosing the cause of a trouble signal.
Trouble signals automatically reset upon removing the cause
of trouble. In addition to these indicators, there is a dual digital display that reads 00 to 99. This display is used to indicate the signal strength of the beam in alignment mode and
to indicate the sensitivity setting of the detector in percent
obscuration when setting the sensitivity of the detector. No
additional equipment is needed for alignment of the beam.
D400-74-00 2 I56-2542-00R
Before installing the transmitter/receiver unit or reflector
in these types of applications special consideration should
be given to insure proper operation of the beam detector.
The beam detector should not be installed in environments
where there is no temperature control and condensation or
icing is likely. Condensation or icing of the reflector surface
or the outer surface of the transmitter/receiver unit will
obscure the light beam resulting in a false alarm. If elevated
humidity levels and rapidly changing temperatures can be
expected then condensation will likely form and the application should not be considered acceptable for the beam
detector. The beam detector should not be installed in
locations where the transmitter/receiver unit, the reflector,
or the optical pathway between them may be exposed to
outdoor conditions such as rain, snow, sleet, or fog. These
conditions will impair the proper operation of the detector
and must be avoided.
Approved Accessories
The following accessories can be purchased separately for
use with this beam detector.
BEAMLRK
The BEAMLRK allows System Sensor reflected beam detectors to be installed at separations between 230 and 328 feet
(70 to 100 meters). At these distances, four 8″×8″ reflectors
must be used to provide enough reflected infrared light.
This kit includes 3 additional reflectors with new test
scale legends. The reflector included with the transmitter/
receiver unit is the fourth reflector to be used. This kit is
not compatible with the multi-mount kit (BEAMMMK).
BEAMMMK
The BEAMMMK allows System Sensor reflected beam detectors and reflectors to be mounted to either a vertical wall or
the ceiling. The kit allows for additional alignment range in
cases where the detector and reflector cannot be mounted
within 10° of each other. The kit includes the hardware
necessary to mount either a single transmitter/receiver unit
or a single reflector. (To mount the transmitter/receiver the
surface mount kit, BEAMSMK, must also be used). If the
transmitter/receiver and the reflector require additional
alignment range two kits are required. The kit is not compatible with the long-range reflector kit (BEAMLRK).
BEAMSMK
The BEAMSMK allows System Sensor reflected beam detectors to be mounted when surface wiring is used. This kit
must be used when mounting the transmitter/receiver unit
with the multi-mount kit (BEAMMMK).

Detector Placement
This section of the manual discusses the placement of projected
beam detectors. Though this information is based upon industry
expertise, it is intended to be used only as a technical guide.
Always comply with the requirements of applicable codes and
standards such as,ULC S524, NFPA 72, National Fire Alarm
Code, as well as directives of the Authority Having Jurisdiction
(AHJ). For general information on the placement of detectors,
read System Sensor’s Projected Beam Detector Application
Guide.
Projected beam detectors are usually located with their
beams parallel to the ceiling. However, they can be mounted vertically or at any angle to protect the area involved.
Since beam detectors sense the smoke buildup over a distance, they are ideal for locations with high ceilings. They
can also be mounted on a wall or ceiling below the level
of a spot type detector, reducing the effects of air stratification. Some typical locations would include large areas with
high ceilings such as atriums, warehouses, and factories.
RTS451/KEYA
The remote test accessory, RTS451/KEYA allows for the beam
detector to be tested remotely. The test accessory provides test
and reset functions and green and red LED’s that mimic the
LED’s on the detector.

NOTE: Projected beam smoke detectors should always
be mounted to stable mounting surfaces. See the
MOUNTING LOCATION section for details.
Some fire codes specify spacing on a given center-to-center
distance between detectors under ideal conditions. This
spacing is based on rooms with smooth ceilings and no
physical obstructions between the contents being protected
and the detectors. Moreover, they are also based on a maximum ceiling height, and on the assumption that the value
and the combustible nature of the contents of the room
being protected do not warrant greater protection or closer
spacing.
In a room with a smooth ceiling, detectors should be
spaced between 30 and 60 feet (9.1 to 18.3m). One-half
that spacing between the beam and the sidewall may be
used as a guide. See Figure 1. The beam detector can be
mounted with the transmitter/receiver on one wall and the

On smooth ceilings, beam smoke detectors should generally be mounted between 12 and 18 inches (0.3 to 0.46m)
from the ceiling. In many cases, however, the location and
sensitivity of the detectors shall be the result of an engineering evaluation that includes the following: structural
features, size and shape of the room and bays, occupancy

Mounting Locations
Beam detectors require a stable mounting surface for
proper operation. A surface that moves, shifts, vibrates, or
warps over time will cause false alarm or trouble conditions. Initial selection of a proper mounting surface will
eliminate false alarms and nuisance trouble signals.
Mount the detector on a stable mounting surface, such as
brick, concrete, a sturdy load-bearing wall, support column, structural beam, or other surface that is not expected
to experience vibration or movement over time. DO NOT

Figure 5a. Reflector Mounting Guidelines
In cases where only one stable mounting surface as defined
above can be used, the transmitter/receiver unit should be
mounted to the stable surface and the reflector should
be mounted to the less stable surface. The reflector has
a much greater tolerance for the unstable mounting locations defined above.
Mounting Instructions
The transmitter/receiver unit may be mounted over a
recessed junction box. The cavity behind the detector is
then used for routing of the wiring from the junction box to

unit should be mounted to the wall such that unit covers the

recessed junction box in the wall completely. If the junction
box is not recessed then you may use the surface mount kit
(BEAMSMK). See the BEAMSMK installation instructions
for surface mounting instructions. The transmitter/receiver
unit can be mounted to the wall using the supplied drilling
template (see Appendix II). The detector base has 4 primary mounting keyholes, one in each corner of the base.
All four hole locations should be used to provide a secure
mounting. The outer housing of the beam detector is held
C0259-00
to the base using four screws. In order to mount the detector you must remove the outer housing first.
Mounting Considerations for Single Ended Beam
Detectors
The reflector can be mounted to the wall using the supplied drilling template (see Appendix III). The reflector
has 4 mounting holes, one in each corner. All four hole
locations should be used to provide a secure mounting.
The reflector must be mounted such that it is within 10°
in both the X and Y planes of the transmitter/receiver unit.
See Figure 5a. The reflector must also be mounted such
that plane of the reflector is perpendicular to the optical
line of sight to the transmitter/receiver unit. The maximum
tolerance for non-perpendicular mounting locations is 10°.
See Figure 5b. If the reflector cannot be mounted within
10° of the transmitter/receiver unit then the multi-mount
kit (BEAMMMK) may be used to provide greater angular
There must be a permanent clear line of vision between the
detector and the reflector. Reflective objects must not be
near the line of vision between the detector and reflector.
Reflective objects too near to the line of sight can reflect
the light beam from the transmitter to the receiver. If this
occurs, the detector will not be able to distinguish these
reflections from those of the reflector and the protected
space will be compromised. Reflective objects should be a
minimum of 4 feet (1.2m) from the line of sight between
the detector and reflector. In cases where reflective objects
cannot be avoided, the complete reflector blockage test can
be used to determine if the installation is acceptable. See
Testing and Maintenance Section of this manual.
adjustment of the transmitter/receiver unit. If the perpen-
dicular plane of the reflector cannot be mounted within 10°
of the optical line of sight then the multi-mount kit can be
used for the reflector. See BEAMMMK instructions.

line of sight between the detector and the reflector can
reflect the light beam from the transmitter to the receiver.
If this occurs, the detector will not be able to distinguish
these reflections from those of the reflector and the protected space will be compromised.
Panes of glass will also absorb some of the light as it
passes through it. This absorption of light will reduce the
acceptable installed distance between the detector and the
reflector.
When the detector has been mounted over a recessed junction
box, all wiring should be routed out of the box and behind the
detector to the bottom of the detector where the terminal blocks
are located. When installing the wiring in the junction box be
sure to leave enough wire in the box to connect to the terminal
blocks. (Approximately 9
″ (23cm) of wire outside of the junction box will be required for proper installation). All wiring to
the detector is done via pluggable terminal blocks. In order to
properly make electrical connections strip approximately 1/4″
(6mm) of insulation from the end of the wire, sliding the bare
end of the wire under the clamping plate screw.
In cases where operation through panes of glass cannot
be avoided some specific installation practices can help to
minimize the effects of the glass. These practices include:
avoid penetration of multiple panes of glass, position the
glass so that it is not perpendicular to the line of sight
between the detector and the reflector, (A minimum of 10°
off perpendicular should be considered), and make certain
that the glass is smooth, clear and mounted securely. The
complete reflector blockage test can be used to determine if
the installation is acceptable. See Testing and Maintenance
Section of this manual.
Where high ceilings (in excess of 30 feet or 9.1 meters)
are present additional beams may be required to detect
smoke at lower levels. See System Sensor’s Projected Beam
Detector Applications Guide for further explanation.
Wiring Installation Guidelines
Always install all wiring in compliance with the Canadian
Electrical Code, and/or the applicable local codes, and any
special requirements of the local authority having jurisdiction.
Proper wire gauges and suitable means for strain relief should
be used. The conductors used to connect beam smoke detectors
to control panels and accessory devices should be color-coded
to reduce the likelihood of wiring errors. Improper connections
can prevent a system from responding properly in the event of
a fire.
Figure 6 shows all the wiring connections to the transmitter/
receiver unit. Figure 7 shows the proper wiring diagram for
either class A or class B operation. Figure 8 shows the connections that are necessary when using one of the optional remote
test stations (RTS451 or RTS451KEYA). Figure 9 shows the
remote output for alarm indication.
WARNING: Disable the zone or system before applying
power to the beam detector to prevent unwanted alarms. When applying power to the beam
detector before the alignment procedure has
been completed the detector may enter alarm
or fault.
Figure 6. Wiring Connections at Detector
Installation wire used for the beam detector shall be no
smaller than 22 AWG (1.0 mm2). For best system performance, all wiring should be twisted pair and installed in
separate grounded conduit. Do NOT mix fire system wiring
in the same conduit as any other electrical wiring. Shielded
cable may be used to provide additional protection against
electrical interference.
When installing the beam smoke detector in applications
where the head unit will be mounted to either a wall or
the ceiling using the multi-mount kit (BEAMMMK) flexible
conduit will be used. The surface mount kit (BEAMSMK)
and multi-mount kit (BEAMMMK) must be installed with
the cable before wiring the unit, according to the instructions supplied with the kit.

Installation / Alignment
Reference Figures 10 through 14 for installation, alignment,
and maintenance.
The alignment of the BEAM200A/BEAM200SA is divided
into four steps: coarse alignment, fine adjustment, final gain
adjustment, and final verification. It is necessary for all four
steps to be executed properly to ensure proper alignment of the
product. If the detector and reflector are mounted per Mounting
Locations and Mounting Instructions sections of this manual and
the alignment procedures are executed properly, false alarms
and nuisance trouble signals will be minimized.
Pre-Alignment Checklist
• Insure that both the detector and reflector are mounted
securely to stable surfaces.
• Insure that all wiring is correct.
• Insure that terminal blocks are fully seated into their
receptacles on the detector.
• Complete any wiring dressing to minimize movement
to the detector once the alignment procedure is completed.
• Insure that the appropriate number of reflectors are
used for the installed distance. Distances between 230
& 328 Feet (70 - 100m) require additional reflectors (4
total). The BEAMLRK accessory should be used in these
cases.
• Insure that the line of sight between the detector and
reflector is clear and that reflective objects are not too
near. See Mounting Instructions for more details.
• Insure that both the detector and reflector are mounted
within their operational parameters for off axis angles.
See Mounting Instructions for more details.
• Disable the zone or system to prevent unwanted alarms
before applying power.
• Insure power to the detector is “ON”.
• Insure that the appropriate address is set on the code
wheels.
D400-74-00 7 I56-2542-00R
You are now ready to begin the alignment procedure.
Step 1. Coarse Alignment
Refer to Figures 11 and 12 for this step.
1. Insure that both of the optics lock-down screws are loosened so that the optics will move feely.
2. Looking through the alignment mirror at both the alignment sight and reflector simultaneously locate the position
of the reflector in the optical sight. This step will require
some practice. It is necessary to train your eyes to shift
focus between the reflector and the mirror in order to
locate the reflector. If the distance between the reflector
C0319-00
and the detector is large it is helpful to place a brightly colored object on the wall near the reflector to aide in seeing
the reflector in the alignment mirror.
3. Once the reflector has been located, begin to adjust both
the horizontal and vertical alignment knobs so that the
reflector becomes centered in the alignment mirror. Take
care in this step. If the optics are incorrectly aligned in this
step, it will not be possible to proceed with the fine adjustment step.
Step 2. Fine Adjustment
Refer to Figures 10 through 12 for this step.
In this step you will be fine-tuning the optics to the reflector. To provide feedback of the signal level coming from the
reflector the dual digital display readout will be used. Due
to the large distance range that the detector can operate
over it is necessary that the detector operate with many different settings of “electronic amplifier gain”. The detector
is capable of determining the appropriate gain setting and
then setting it itself via on-board processing algorithms.
There are no external gain settings on the detector that
must be set by the operator. Periodically throughout the
fine adjustment step the detector will need to re-adjust its
“electronic amplifier gain” setting. When this occurs it will
be indicated by the dual digital readout as “- -”. When this
occurs, cease any further adjustment until the display again
reads a number value.
1. Insure that neither you nor any other objects are in the line
of sight between the detector and the reflector.
2. Depress the Alignment switch once. Both the digital display
and the yellow LED should turn on indicating that alignment mode has been entered. The display should begin
reading “- -” signifying an electronic gain adjustment. After
a few moments the display will indicate a numeric value
near 20. If the display reads “Lo” then the detector is not
receiving enough light from the reflector. Go back and
repeat the course alignment step and verify that the proper
number of reflectors is used for the installed distance.
going back and forth between them until a peak value is
indicated. If a value of 90 is achieved, the detector will readjust the electronic gain once again. This will be indicated
by a “- -” reading on the display. When this happens halt any
further adjustment until the display again reads a numeric
value. This process may occur more than once during the
fine adjustment step.
Note: Each time the display reads a value of 90 or greater
the detector will reduce the electronic gain. Each time
the display reads a value of 10 or less the detector will
increase the electronic gain.
4. Once satisfied that it is not possible to achieve a higher
reading on the display depress the alignment switch to
complete the fine adjustment step. The digital display readout will turn “OFF” and the yellow LED will remain “ON”.
Note: It may not be possible to achieve a value near 90 on the
display during the last adjustment iteration. The final
value of the display will not likely be near 90. This is normal. It is due to the detector reducing its electronic gain
each time a value of 90 is achieved. When this occurs the
detector resumes with less electronic gain than previously when 90 was achieved. Less gain makes it more
difficult to achieve higher values. Final values anywhere
between 20 and 90 are acceptable if no further increase
can be achieved.
Note: The alignment procedure is not complete yet.
At this time it is possible to set the sensitivity of the detector using the sensitivity switch and digital display. See the
Sensitivity Selection section of this manual for further details.
Step 3. Final Gain Adjustment
Refer to Figure 13 for this step.
In this step, the detector will electronically adjust its internal gain one final time. It is necessary to complete this
step with the outer housing installed since the housing will
change the amount of light received from the reflector.
Note: The display will continue to read “Lo” until the detector
receives enough light from the reflector to continue with
the fine adjustment step.
Note: In alignment mode (indicated by the yellow LED and the
numeric display) the sensitivity select and test switches
are disabled.
3. With the display reading a numeric value, begin adjusting
the horizontal and vertical alignment knobs one at a time
in the direction that increases the numeric signal level on
the display. Continue adjusting each axis one at a time
D400-74-00 8 I56-2542-00R
1. Install the outer housing of the detector. The housing is
installed by tightening four screws, one in each corner of
the housing. The screws are captivated in the plastic of the
housing and cannot fall out during assembly.
Note: The housing contains a gasket seal that protects the
detector circuitry from corrosion and moisture sources.
To insure that the gasket seal performs correctly it is
necessary to fully tighten all four of the screws that hold
the outer housing in place.
2. Remove the protective film from the front surface of the

3. To initiate the final electronic gain adjustment, the reset
switch must be depressed. Once depressed the yellow LED
will begin to blink. This indicates that the detector is adjusting the electronic gain setting. Once complete, the yellow
LED will stop blinking and the green LED will begin blinking. This indicates that the gain adjustment was successful.
Note: Use caution not to block the line of sight between the
detector and reflector in this step.
4. Install the outer aesthetic ring by snapping it onto the outer
housing.
Note: If the outer aesthetic ring has been painted insure that
the paint is completely dry before proceeding with this

Step 4. Final Verification
This step is required to insure the detector has been setup correctly and will detect smoke at the proper sensitivity level.
1. With the detector functioning (indicated by the green LED
blinking), completely block the reflector with an opaque
material. (Due to the high optical efficiency of the reflector the selection of the opaque material used to block the
reflector is not critical. Acceptable materials include, but
aren’t limited to, this manual or the cardboard packaging
inserts.) See Figure 14. The detector should enter the fault
condition (indicated by the fault relay and the yellow LED
(see Appendix I). If the detector does not enter the trouble
condition there is a problem with the installation refer to
the troubleshooting section in Appendix I for further assistance.
2. Complete a sensitivity test of the detector. Refer to the
Sensitivity Testing section of this manual for the appropriate procedure.
3. If the orange sticky paper was used to aid in the location of
the reflector in the alignment mirror it should be removed
now. It is no longer necessary.

between the detector and the reflector per ULC and UL268. The
chart below is used to determine which selections are acceptable
for your installed distance. The sensitivity of the detector can
be set only when the housing is removed and the detector is not
in the fine adjustment step of the alignment mode, indicated by
the illumination of the dual digital display. To set the sensitiv
ity depress the sensitivity button one time. See Figure 10. Once
the switch is pressed the digital display will illuminate and read
the current sensitivity setting in percent obscuration. To change
the sensitivity continue to depress the sensitivity switch until
the desired setting is achieved. The digital display will turn off
automatically if no further switch presses occur.

In addition to the four standard sensitivity selections the
detector has two Acclimate settings. When either of these
settings is chosen the detector will automatically adjust its
sensitivity using advanced software algorithms to select the
optimum sensitivity for the environment. The sensitivity
will be continuously adjusted within the ranges specified
in the chart above.
Sensitivity
Total obscuration can be converted to percent per foot,
assuming uniform smoke density for the entire length of
the beam. The charts below converts total obscuration to
percent per foot for all acceptable sensitivity settings.
Short Circuit Isolation
The detector includes an on-board circuit isolator that
allows for NFPA72 style 7 operation. In cases where style 7
operation is not desired the isolator can be disabled using
the two shunts on the circuit board. See Figure 10 for jumper locations. When the jumpers are present the isolator is
disabled. This is the default state.
Sensitivity Selection
The detector has six sensitivity selections. Each of these selections is only acceptable over a specific distance separation

NOTE: Before testing, notify the proper authorities that the
smoke detector system is undergoing maintenance,
and therefore the system will be temporarily out of
service. Disable the zone or system undergoing maintenance to prevent unwanted alarms.
Detectors must be tested after installation and following
periodic maintenance. The sensitivity of the BEAM200A/
BEAM200SA may be tested as follows:
NOTE: Before testing the detector, check for the presence of
the flashing green LED at the receiver, making sure
not to disturb or block the beam. If it does not flash
and the detector is not in trouble or alarm, power has
been lost to the detector (check the wiring).
A. Calibrated Test Filter
The sensitivity of the detector can be tested using an
opaque material to cover the reflector by an amount indicated by the graduated scale on the reflector. (Due to the
high optical efficiency of the reflector the selection of the
opaque material used to block the reflector is not critical.
Acceptable materials include, but aren’t limited to, this
manual or the cardboard packaging inserts.)
Figure 14. Reflector Test Card Procedure
C0267-00
Refer to Figure 14 for this procedure.
1. Verify the sensitivity setting of the detector in % obscuration. See the Sensitivity Selection section of this manual for
sensitivity determination if sensitivity is unknown.
2. Place the blocking material over the reflector, lining it up
with the graduated marks that are 10 less than the detector’s setting in % obscuration. The detector should not
alarm or fault. Keep the material in place for a minimum of
1 minute.
3. Place the blocking material over the reflector lining it up
with the graduated marks that are 10 more than the detectors setting in % obscuration. The detector should enter
alarm within 1 minute.
4. The detector can be reset with the reset switch on the
detector unit or remote reset.
5. Notify the proper authorities that the system is back on
line.
If the detector fails this test several steps should be taken
to determine if the detector is faulty or simply needs to be
re-adjusted before returning the unit. These steps include:
1. Verify all wiring connections and appropriate power is
applied to the detector.
2. Verify that the optical line of sight is free from obstructions
and reflective objects.
3. Apply the maintenance procedure in this manual. Repeat
the test procedure. If the detector still fails the test procedure proceed with step 4.
4. Repeat the alignment procedure in this manual. If the alignment procedure is successful repeat the test procedure. If
the detector still fails the test it should be returned.
D400-74-00 11 I56-2542-00R
Note: For the BEAM200SA the external power supply must be
connected for the test switch to work.
B. Test Switch
The detector can be tested using the local test switch on
the transmitter/receiver unit or remotely using the remote
test station.
3. Apply the maintenance procedure in this manual. Repeat
the test procedure. If the detector still fails the test procedure proceed with step 4.
The remote test station, RTS451 or RTS451KEYA, can be used
with the BEAM200A/BEAM200SA beam smoke detector.
Follow instructions included with the test station for proper use.
See Figure 8 (Remote Test Station) for wiring diagram.
The BEAM200SA is equipped with an integral sensitivity test
feature that consists of a calibrated test filter attached to a servo
motor inside the detector optics. When a test is initiated using
the remote test station or local test switch the test filter is moved
in the pathway of the light beam. The on-board microprocessor then determines if the proper level of signal reduction is
received at the receiver. If the proper level of signal reduction
is received the detector will enter alarm. If the proper level of
signal reduction was not achieved, indicating that the sensitivity of the detector is out of tolerance, the detector will enter the
trouble condition.
Always perform a complete reflector blockage test as in step
4 of the Installation/Alignment procedure to insure that the
pathway between the detector and reflector is clear.
Note: For the BEAM200A this test does not satisfy the require-
ments of NFPA72 and/or ULC for periodic maintenance
and sensitivity verification of beam type detectors.
For the BEAM200SA this test in conjunction with the
complete reflector blockage test (see step 4 of the
Installation/Alignment procedure in this manual) does
satisfy the requirements of NFPA72 and/or ULC for periodic maintenance and sensitivity verification of beam
type detectors.
4. Repeat the alignment procedure in this manual. If the alignment procedure is successful repeat the test procedure.
If the detector still fails the test it should be returned for
repair.
Note: For the BEAM200SA, the external power supply must be
connected for the test switch to work.
Maintenance
NOTE: Before cleaning the detector, notify the proper
authorities that the smoke detector system is undergoing
maintenance, and therefore the system will be temporarily out of service. Disable the zone or system undergoing
maintenance to prevent unwanted alarms.
1. Carefully clean the outer housing lens face. A damp soft
cloth with a mild soap may be used. Avoid products with
solvents or ammonia.
2. Carefully clean the reflector. A damp soft cloth with a
mild soap may be used. Avoid products with solvents or
ammonia.
3. Notify the proper authorities that the system is back on
line.
Painting
The outer aesthetic ring may be painted using a spray or
brush type paint of appropriate type. See specification section of this manual for paint types.
If the detector fails this test several steps should be taken
to determine if the detector is faulty or simply needs to be
re-adjusted before returning the unit. These steps include:
1. Verify all wiring connections and appropriate power is
applied to the detector.
2. Verify that the optical line of sight is free from obstructions
and reflective objects.
