LOCATING THE DETECTOR & SELECTING A LE NS

First, choose the type of coverage which will be best for the
particular area you need to protect.

Standard Wide-Angle Lens

Corner mounting with this lens is preferred as it provides the
best overall coverage. Choose a corner where the path of an
intruder will most likely cross beams, as opposed to walking
towards or away from them. This lens is intentionally made with
an 85 degree angle of view, to help prevent curtains on windows
from being in detection zones.
Sources of heat, such as radiators and space heaters, do not
usually pose a problem as long as hot air from them does not

blow directly

head radiant heaters, these produce very high levels of infrared
energy and can heat the unit at some distance. Mount the unit
as far from these as possible. Do not mount the unit where the
sun can shine directly on it. Mount it away from the direction of
sunlight.

locate the

detector as
high as possible (7 ft. minimum) and avoid placement that
would allow the pets to get within 6 ft. of the detector. It may be
necessary to mask a zone with the supplied material if a stair­case is close to the detector and directly in a zone. It is also
possible to adjust beams laterally by sliding the lens and re­tainer horizontally within its stops.

Pet-Alley Lens (LENS817)

For larger pets use a Pet-Alley Lens (LENS817). This lens pro­vides the same pattern and coverage as the standard Wide­Angle lens, but there are no lower zones. This creates an un­protected “Pet Alley” in which a larger pet can freely move

about. The

removing the screw in the center of the board.

Note:

the screw
is attached to the circuit board and will not separate when
removed. Third, determine the wire entry points on the housing.
The housing provides four possible wire entry points, two for
surface wiring and two for hidden wiring. Determine which entry
is most convenient and punch out or remove the thin plastic
section. Fourth, mount the housing to the wall. There are three
mounting options to choose from depending on the desired
location: flat wall mounting, corner mounting or using the swivel
bracket (SVL2) for ceiling and wall mounting where it is advanta­geous to tilt or aim the unit along a wall.

Note:

using two units on
swivel brackets mounted side by side it is possible to cover
almost 180 degrees when mounted on a flat wall. If using the
swivel bracket refer to the instructions with the bracket. For wall
or corner mounting simply hold the case in the desired location
and using the supplied screws push through the appropriate thin
wall mounting screw holes and attach the unit with two or four
screws.

Note:

Do not over tighten the screws as this can distort
the case and compromise the air seal of the unit, because not all
walls are flat and all corners are square. Reinstall the circuit
board and proceed to wire the detector.

WIRING & TERMINAL DESCRIPTIONS

Refer to the wiring diagram and terminal descriptions, connect
the appropriate wire to the corresponding terminal. When you
have finished wiring the terminals seal the opening around the
wire entry hole and any other unused holes with the supplied
sealer.

CONFIGURING THE PIR1680

Low Temperature Alarm for Heating System Monitoring (a
Patented Feature

The PIR1680 has the ability to activate a Low Temperature
Output in the case of the ambient temperature falling below
40°F.

This feature functions exactly the same as if you had

purchased a separate temperature switch

ture, connect a jumper across pins LT and wire the Trouble
Output (terminal 5) into the positive terminal of a zone pro­grammed for 24 Hour protection. This output signal will remain
active for as long as the temperature remains below 40°F, when
the temperature rises several degrees above this the output will
reset .

High Temperature Alarm for Cooling System Monitoring (a
Patented Feature)

The PIR1680 has the ability to activate a High Temperature
Output in the case of the ambient temperature rises above 90°F.

This feature functions exactly the same as if you had purchased
a separate temperature switch

a jumper across pins HT and wire the Trouble Output (terminal

5) into the positive terminal of a zone programmed for 24 Hour
protection. This output signal will remain active for as long as the
temperature remains above 90°F,when the temperature falls
several degrees below this the output will reset .

Note:

If the unit is in a high or low temperature condition, the

LED will glow dimly instead of being completely turned off , this

can be used to test the units temperature monitoring feature. If
it is desired to test the temperature monitoring feature, it will be
necessary to either trip the unit or wait several minutes for the
unit to measure the temperature, because the room temperature
is measured every 10 minutes or each time an alarm is tripped.
You will need freeze spray or a freezer to test low temperature or
to test high temperature a hairdryer will do. Heat or cool the
temperature sensor (refer to Circuit Board Detail), then trip the
unit, assuming it hasn’t done that already and let it settle and
observe the LED for a dim glow.

Self Test/Trouble Output

The PIR1680 will periodically test its circuitry to insure it is
operating in the manner for which it was designed. Self Test
failure will be indicated by the rapid blinking of the LED (do not
confuse it with the unit's warm up period, in which it will also
blink for approximately 60 seconds). To send a trouble output to
the control panel on self test failure, install a jumper connector
across pins ST and wire the Trouble Output (terminal 5) into the
positive terminal of a zone programmed for 24 Hour protection.

Note:

This output is a 1 second momentary activation. This
makes it it possible to differentiate a temperature condition from
a self test failure on the same zone. A temperature signal will not
immediately be followed by a restore signal (the temperature
must rise several degrees first). However, because the selftest
failure activation is momentary the zone will report an open
followed by a restoral.

Appropriate panel programming is re-

quired.

LED Disable Jumper

To prevent the walk test LED from turning on, remove the
jumper from the pins labeled LED DISABLE. Removing this
jumper will not affect the flashing of the LED on self test failure
or the dim glow during a high/low temperature condition.

Sensitivity Setting (SEN Jumper)

The unit is shipped with no jumper in this position. This is the
normal sensitivity mode and is recommended for most installa­tions whose coverage area does not exceed 30’ x 35’. Cov erage
out to 50’ x 50’ is possible in this mode, but the intruder will have
to cover a larger distance before detection. To have faster catch
performance this jumper must be installed.

Note:

Advanced
signal processing will be defeated in this high sensitivity mode.
DO NOT INSTALL THIS JUMPER IF PETS OR RODENTS ARE
PRESENT. If LENS818 (Barrier Lens) or LENS840 (Long Range
Lens) is used, it is recommended that the SEN jumper be
installed.

Vertical Aiming

(refer to lens coverage pattern)
The height scale that is on the board is intended to make v ertical
aiming quick and easy. If the board is set to the same number as
the height the unit is mounted at, the unit will be aimed for
maximum coverage. However, if the unit is used for less then the
maximum range, move the board up (towards 12 ft.) and walk
test the unit.

Note:

If the wall upon which the unit is mounted is not vertical,
move the board up or down and walk test the unit. If using the
Long range or Barrier Lens, set the board to 12 feet on the
height scale as a starting point as aiming accuracy for long
range lenses can greatly affect performance.

Horizontal Aiming

(refer to lens coverage pattern)
The lens may be moved left to right within its holder to help avoid
problem areas. However, the most effective solution for a possi­ble problem area is to block the zone, by applying a piece

of lens foil (supplied) to the inside segment of the lens repre­senting that zone.

Installations with Pets

The PIR1680 will provide good immunity to small pets in most
applications. The pet or pets should be small (less than 20 lbs.).
Several small cats are acceptable. If you have three or more
large ones, we recommend that the NAPCO C200AP dual
technology sensor be used. Mount the unit as high as possible.
If the unit is above a chair or other piece of furniture that the pet
may climb onto, mask the look down beam. Make certain the
sensitivity (SEN) jumper is off (normal sensitivity). If a stair case
is in the field of view and closer than 20 ft. from the unit, it may
be necessary to mask that beam.

REPLACING THE LENS

The lens is mounted behind a Lens Support insert that fits inside
the front cover. To install one of the accessory lenses, proceed

as follows

1. Carefully lift the lens cover
from the housing.

2. While pushing the lens in at
the top, with fingers straddling
the LED jewel, press down at
the top of the Lens Support as
shown until the support clears
the three top retainers. Be care­ful not to dislodge the look
down-lens window.

:

2. Push the Lens Support up until it clears the three bottom
retainers and remove the assembly.

3. Slide out the lens.

4. Install the replacement lens with the grooved side in and the
with the lens not in the up side down position. All lenses are
marked with with the word top stamped on the border, this may
be difficult to see, so as a rule put the taller lens segments up.

5. Install the retainer assembly into the front cover. Slip the Lens
Support behind the lower retainers, then push in at the top until
the Lens Support snaps into place.

COMPLETING THE INSTALLATION

Allow at least three minutes for the unit to stabilize after apply­ing power, during this time the unit will perform its own self diag­nostics and set a baseline detection level. The LED will flash
rapidly for approximately 1 minute and not function until the unit
is ready. If the unit was installed after being kept in a hot or cold
vehicle allow the unit to operate with its cover in place for about
15 minutes. This will insure that the unit has measured the
proper room temperature. Walk test the unit to insure the de­sired coverage, making any board height adjustments that may
be necessary.

Note:

One common cause of short range is hav­ing the lens in up side down, always check this! During walk
test, the unit will go into a zone finding mode for 15 seconds
after each trip. This will cause the LED to light each time a
beam is entered. To view the normal detection pattern remain
motionless for at least 15 seconds between walk tests.
