April 2000

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

Use this motion sensor to protect locations where door/win-
dow 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.

 PIR 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.

This wireless motion sensor includes the following features:

❑

35 feet by 40 feet coverage area

❑

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

❑

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

❑

Supervisory signal transmitted every 64 minutes to the 
control panel

❑

Sensor low battery reports (trouble) to the control panel

❑

Field-selectable sensitivity options (standard setting 
required for pet applications)

This PIR was designed for use in the presence of pets hav-
ing a combined weight of up to 40 pounds.  The following 
installation guidelines must be met to provide this false 
alarm immunity.

1.

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

2.

The required mounting height is 7 1/2 feet.

3.

Position the sensor to protect an area where an intruder 
would be most likely to walk across the detection pat-
tern (see Figure 1).

4.

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

5.

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

6.

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

7.

Do not aim the sensor at windows, fireplaces, air condi-
tioners, area heaters, forced air heating vents, or place 
it in direct sunlight.

8.

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

9.

Mount the sensor permanently on a flat wall or in a cor-
ner.  Do not set it on a shelf.

10. Windows should be closed in any area which has an 

armed motion sensor.

11. The pet must not be allowed to climb on objects such as 

furniture, boxes, etc. within the field of coverage.  See 
Figures 2 and 3 to determine the sensor’s field of cov-
erage.

12. Room temperature must be kept at 60º F or higher.

13. The sensitivity switch must be set to Standard.
