Summary
Summary
A motion sensor (passive-infrared or PIR) detects movement by sensing the infrared energy
emitted from a body as it moves across its field of view. When this motion is detected, the sensor
transmits an alarm signal.
emitted from a body as it moves across its field of view. When this motion is detected, the sensor
transmits an alarm signal.
Install motion sensors to protect areas 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 can
also provide backup protection in areas where door/window sensors exist.

This wireless motion sensor includes the following features:
•
Field-selectable coverage area; 33 or 50 feet
•
Field-selectable sensitivity modes; 2-pulse or 4-pulse
•
135-second transmitter lockout time after an alarm that helps extend battery life
•
Cover-activated tamper
•
Supervisory signal transmitted every 64 minutes to the control panel
•
Sensor low battery reports (trouble) to the control panel
Included with the sensor is a thin cardboard undercrawl mask and snap-in plastic masks
(installed at the factory). Self-adhesive masking strips are also included.

Installation
•
If possible, locate sensors within 100 feet of the panel. While a transmitter may have an
open-air range of 500 feet or more, the installation site can have a significant effect on trans-
mitter range. Changing the sensor location may help overcome adverse wireless conditions.

•
Mount the sensor permanently on a flat wall or in a corner. Do not set it on a shelf.
•
For installations without pets, the required mounting height is 7 1/2 feet.
•
Mount the motion sensor on an insulated, outside wall facing in.
•
Mount the motion sensor on a rigid surface which is free from vibrations.
•
Position the sensor so it faces a solid reference point, like a wall.
•
Do not aim the sensor at windows, fireplaces, air conditioners, heaters/heating vents, or place
it in direct sunlight.

•
Position the sensor to protect an area where intruders are most likely to walk across the
detection pattern (see Figure 1).
