Maintenance

2.

Exit the panel’s programming mode.

3.

Return the PIR to its mounting plate.

At least once a year, the range and coverage should be veri-
fied for proper operation. The end user should be instructed 
to put the sensor in walk test mode and walk through the far 
end of the coverage pattern to verify proper detection.

When battery replacement is necessary, observe proper 
polarity (as shown in the battery compartment) when 
installing the new battery, or the sensor may be damaged. 
Be sure to note that as you look at the battery compartment, 
on the left side the positive side is down and on the right 
side the positive end is up. When the battery is replaced, 
wait at least 3 minutes after installing the battery before 
activating the walk test mode. See Figure 7 for battery loca-
tions.

Final testing should be done to verify radio signal integrity 
and confirm control panel programming and response. The 
actual transmitter range can be determined by performing a 
sensor test as follows:

1.

After the sensor has been mounted, remove it from its 
mounting plate and activate the tamper switch to start 
the walk test mode.

2.

Replace the sensor in its mounting plate.

3.

Place the control panel in test mode. Move across the 
detection pattern until the sensor’s LED turns on. 
STOP your motion.

4.

Listen for the appropriate system response. If the sys-
tem does not respond, proceed to Troubleshooting.

Use the following guidelines if the system does not respond 
correctly when the sensor is activated. 

❑

Check programming and re-program sensor into panel 
if necessary.

❑

Move the sensor to another location and test for correct 
response.

1.

Test the sensor a few inches from the original position.

2.

Increase the distance from the original position and 
retest until an acceptable location is found.

3.

Mount the sensor in the new location.

4.

If no location is acceptable, test the sensor as described 
below:

❑   Test a known good sensor at the same location.
❑   If the system does not respond, avoid mounting a 

sensor at that location.

❑   If the replacement sensor functions, return the 

problem sensor for repair or replacement.
