INSTALLATION HINTS
Do not install where the detector is exposed to direct sunlight or
directly above strong sources of heat.
Make sure the detection area does not have obstructions
(curtains, screens, large pieces of furniture, plants, etc.) which
may block the pattern of coverage.
Avoid locating a unit in areas which contain objects likely to
produce a rapid change in temperature, such as central heating,
radiators or ducts (or heaters of any kind), air conditioners, open
flame, etc.
Install the detector at a height of approximately 7 feet (2.1m)
from floor. Do not mount on an unstable surface.
IMPORTANT: Avoid running alarm wiring close to telephone line
and alarm sounder wiring.
PROTECTION PATTERNS
Note: The protection patterns shown for wide angle and long
range mirrors can be modified to suit the needs of a particular
area by selective use of the masking strips supplied.

INSTALLATION
A. Changing from Wide Angle to Long Range Coverage:
1. Remove front cover by inserting a screwdriver blade in the
groove between cover and base (see Diagram 1), rotating
blade to override snap fit, and then lifting cover off.
2. Spread either or both plastic prongs holding the wide angle
(35 ft/10.6m) mirror and remove the mirror (Diagram 2).
3. Insert one side of the narrow angle (70 ft/21.3m) mirror
under a prong and snap the other side under the other
prong. Make sure that the mirror sides are squarely in
their corner rests and are held securely under the prongs.
Note: Mirror surface should be free of dirt, foreign matter
and fingerprints. Use a clean dry soft cloth to wipe mirror
surfaces, if required.
B. Normal Wall Mounting:
Note: For ANPI approved installations, you cannot use
the mounting plate.
INSTALLATION INSTRUCTIONS
1. Remove the front cover as shown in Diagram 1.
2. Mount the wall plate to a firm vertical surface (flat on wall
or in corner). Position the plate so that field wiring is
centered in the rectangular slot at the top of the plate.
See Diagram 3 and Detail A.
wide-angle or long
3. Feed wiring through top access hole of detector (past foam
draft protector) but do not connect to terminal block yet.
4. Attach unit to wall plate by engaging all four hooks on the
plate into slots on the rear of the base and by pressing
downward (see Diagram 3). (Puncture the label on the
back of the base before installing.)
Note 1: The PIR is locked to the wall plate by a spring tab that
engages a square opening in the housing base (see Diagram 3).
The PIR can only be removed by cover removal, depression of
the tab from the inside with a small-blade screwdriver and then
sliding the PIR upward.
Note 2: If the PIR is to be mounted on a flat wall without its
mounting plate, install a 3mm screw into the wall at the planned
center (side-to-side) of the PIR, 1 inch (25mm) below the
planned top of the PIR. Leave 1/8" (3mm) clearance between the
screw head and the wall. Hook the PIR on the wall screw,
puncturing the label, and insert two screws into the mounting
areas on both sides of the mirror.
C. Inverted Mounting:
If small pets have access to the area protected by the detector,
this section pertains.
• The detector may be installed approximately 3 ft to 3- 1 / 2 ft (1m)
from the floor, provided furniture or other objects do not
obscure the pattern of protection.
• The detector and wall plate must be mounted inverted (the PIR
window at the top) with the wall p!ate tilted forward
(downward). Two self-adhesive rubber spacers have been
provided to aid in tilting the wall plate.
• It must be noted that although this procedure adjusts the PIR
zones so that small animals will not be detected, a crawling
intruder will ALSO go undetected.
1. The spacers are to be used with the wall plate only when
the wide angle mirror is in use.
Mounting flat on a wall:
Assemble the two spacers, one above the other, and affix the
combination to the rear of the plate, directly in line with the
single mounting hole located at the end of the plate opposite
to the wire entry access cutout.
Corner mounting:
Affix one of the spaces to the rear surface of each of the two
corner mount tabs on the wall plate, on the end opposite to
the wire entry access cutout.
2. Follow "Normal Mounting" steps 2, 3 and 4 described
previously, but orient the wall plate so that the wire entry
access cutout in the wall plate is positioned at the bottom.
3. When the detector is mounted in an inverted position, that
portion of the detector mirror which normally provides a
downward beam of protection will now provide a beam that
points upward. This will apply to both mirrors (long range
and wide angle). If possible, install the detector so that this
now upward-pointing beam is not directed at ceiling areas
that include heating or air conditioning ducts and vents or
lighting fixtures. If these IR sources cannot be avoided, the
upward-pointing segments of each mirror should be
masked to avoid the possibility of false alarms, as indicated
in the diagrams herein.
a. Remove the mirror from the detector, referring to a
previous page for information on mirror removal.
b. Mask the appropriate portion of each mirror as shown
in the diagrams below, using masking strips supplied.
WIDE AREA
Be sure to cover only the area shown.

c. Replace the mirror, making sure it is securely in
position before installing the cover.

D. Optional Ceiling Mounting:
The versatility of this passive infrared motion detector permits
optional ceiling mounting, using the Long-Range ("Curtain")
mirror. This will provide a 15-20 ft (4.5-6m) forward-looking
"curtain" pattern as illustrated in Diagram 4.
The mounting procedure is the same as that for "Normal Wall
Mounting" except that the unit is ceiling mounted with the
window facing toward the detection area.
E. Mirror Masking:
The masking strips that have been supplied are designed for
application in one or more mirror segments to produce a
protection pattern that suits the particular requirements of the
protected area.

shown.
WIRING CONNECTIONS
Bring both polling loop wires through the wire access hole near
the terminal block and connect to screw terminals (see Diagram
5). OBSERVE POLARITY!
Pulse Count Option:
Each detector includes Pulse Count circuitry that provides
stability in adverse environments to minimize false alarms This
circuitry is active when the switch #7 on the circuit board is set

Simply peel off the appropriate pressure-
from areas where you anticipate

to the PULSE COUNT position (see Diagram 5). The detector will
then normally signal an alarm within 3 to 4 steps, since the
processing logic requires more complex motion than just a
momentary event.
For long-range applications where the detector is used to protect
narrow corridors, or where single protective zones are directed
through doorways or room openings, the pulse count option must
be disabled (see Diagram 5) to provide an instant alarm
response.
SELECTING AN ID NUMBER
Make all identification number selections by arranging the
switches on the circuit board. The ID number is equal to the sum
of the switch values in the "OFF" position. Each switch has a
different value and should be set according to Table 1.
TEST PROCEDURES
IMPORTANT: Two-minute warm-up is required after applying
power. Testing should be conducted with the protected area
cleared of all people. Disarm the protective system's control
during the test procedure to prevent reporting of unwanted
alarms.
Walk-Test:
Place PULSE COUNT SW #7 to instant response, left, position.
Place WALK-TEST SWITCH #8 to walk-test, left, position (see
Diagram 5). Replace front cover and walk through protective
zones, observing that the detector's LED lights whenever motion
is detected.
The LED will only be active and should only be used during walk-
test procedures. When walk-test is completed the walk-test
switch #8 must be set to the right position (DISABLED).
The panel may be able to control the walk-test function remotely. In
order for panel to do this, walk-test switch #8 must be set to the
right position (DISABLED).
Notes: In the instant response mode, the LED stays lit for
approximately 1 to 2 seconds after detecting motion. In
the event that switch #7 is placed in the pulse count, right,
position, the LED will illuminate for up to approximately 4
seconds when the detector verifies intrusion.
Make certain to test the unit in the mode it will be used.
For example, if pulse count is to be used, then the PIR
should be walk-tested with switch 7 set to pulse count,
right, position.
The absolute range of all Passive IR units is subject to variation
because of different types of clothing, backgrounds and ambient
temperature. For this reason, ensure that the most likely intruder
routes are well within the PlR's protective zones and that walk-
testing is carried out along the routes.
MAINTAINING PROPER OPERATION
In order to maintain the detector in proper working condition, it is
important that the following be observed by the user.
1. Power should be provided at all times. The unit's
control/communicator should have standby power
available for at least 4 hours of operation during
emergencies.
2. Units should never be re-aimed or relocated without the
advice or assistance of the alarm service company.
3. The physical surroundings of the protected area
should not be changed. If furniture or stock is moved, or
air conditioning or additional heating is installed, the
system may have to be readjusted by the alarm service
company.
4. Walk-tests should be conducted frequently (at least
weekly) to confirm continued proper coverage by each
detector.
TO THE INSTALLER
Regular maintenance and inspection (at least annually) by the
installer and frequent testing by the user are vital to continuous
satisfactory operation of any alarm system.
The installer should assume the responsibility of developing and
offering a regular maintenance program to the user, as well as
acquainting the user with the proper operation and limitations of
the alarm system and its component parts. Recommendations
must be included for a specific program of frequent testing (at
least weekly) to ensure the system's operation at all times.
