SAW PIR and Pet Immune Motions Sensors with

1.5 V Lithium Batteries Installation Instructions

Product summary

A motion sensor (passive-infrared or PIR) detects movement
within a specific area by sensing the infrared energy emitted
from a body as it moves across the sensor’s field of view.
When this motion is detected, the sensor transmits an alarm
signal to the control panel.

Figure 1: SAW PIR and Pet Immune Motion Sensors

Use these motion sensors to protect locations where
door/window sensors are impractical or not needed. For
example, use a motion sensor to protect large areas or open
floor plans. Motion sensors also provide backup protection for
door/window sensors.

The Pet Immune SAW PIR (60-807-02-95R) utilizes advanced
signal processing, a new custom designed lens, and a new
custom designed sensing element. The combination of these
improvements provides false alarm immunity for pets with a
combined weight of up to 40 pounds while still providing
superior human catch performance.

Note: Use only AA 1.5 Volt Lithium Iron Disulfide batteries
(part # 60-931) with this product. Do not substitute any other
brand/type of batteries.

These wireless motion sensors include the following features:

• Cover-activated tamper (optional wall-activated tamper is
included).

• Supervisory signals transmitted every 64 minutes to the
control panel.

• Sensor low battery reports (trouble) to the control panel.

• Field-selectable sensitivity options (60-639-02-95R).

Installation guidelines

Use the following guidelines for installing motion sensors.

• If possible, locate sensors within 100 ft. of the panel. While
a transmitter may have a range of 500 ft. or more out in
the open, the environment at the installation site can have
a significant effect on transmitter range. Sometimes a
change in sensor location can help overcome adverse
wireless conditions.

• The recommended mounting height is 7 1/2 ft., but the
sensor can be mounted from 5 to 8 ft. high in the corner of
the area you want to protect. See the animal alley lens
guidelines for mounting the optional animal alley lens (60­639-02-95R only). Higher mounting provides better range
(up to 35 ft.), and lower mounting provides better
protection close to the motion sensor (see Figure 3 on

e 2 and Figure 4 on page 2). The optional swivel

pag
mount (part #60-737) can be used for difficult mounting
locations with the SAW PIR (60-639-02-95R) only.

• Position the sensor to protect an area where an intruder
would be most likely to walk across the detection pattern
(see Figure 2 on page 2).

• 35 by 40 ft. coverage area.

• Masking kit provided to block portions of the coverage
area (60-639-02-95R).

• Three minute transmitter lockout time after an alarm that
helps extend battery life.

• Mount the motion sensor on a rigid surface which is free
from vibrations.

• The pet must not be allowed to climb on objects such as
furniture, boxes, etc. within the field of coverage. See
Figure 3 below to determine the sensor’s field of coverage.

• Mount the sensor permanently on a flat wall or in a corner.
Do not set it on a shelf.

• Windows should be closed in any area which has an
armed motion sensor.

• A pet will trigger a (60-639-02-95R) motion sensor. See
animal alley lens guidelines to use a motion sensor when
pets are present, or use the Pet Immune PIR (60-807-02­95R).

• Mount the motion sensor on an insulated, outside wall
facing in.

• The sensor (60-807-01-95R) must be incline-mounted on
a wall surface or incline mounted in a corner at a mounting
height of 7.5 ft. (see Figure 4 below).

The sensitivity switch must be set to Standard (60-807-01-

•
95R).

• Room temperature must be kept between 60 and 120°F.

• Position the sensor so it faces a solid reference point, like
a wall.

• Do not aim the sensor at windows, fireplaces, air
conditioners, area heaters, forced air heating vents, or
place it in direct sunlight. Sudden changes in temperature
may trigger a false alarm from these devices.

• Do not mount the sensor near duct work or other large
metallic surfaces which may affect the RF signals (see RF
Testing). Actual acceptable transmitter range should be
verified for each installation.
