Maintenance
Test the sensor at least once a year to verify proper range and
coverage. Instruct the end user to put the sensor in walk test
mode and walk through the end of the coverage pattern to verify
proper detection.
Battery replacement
When you replace the batteries, observe proper polarity (as
shown in the battery compartment) to avoid damage to the
sensor.
CAUTION:
Replace only with two AA 1.5 V alkaline
batteries. Dispose of used batteries
according to the manufacturer's
instructions and local government
authorities.
To replace the batteries, do the following:
1.
Remove the sensor from the mounting plate and slide the
cover off the sensor to reveal the battery compartment.
2.
Remove the batteries and replace with the new ones. Be
sure to observe polarity. As you look at the battery compart-
ment, on the left side the positive end is down and on the
right side the positive end is up (Figure 4 on page 2).
3.
Wait at least three minutes after installing the batteries
before you activate walk test mode.
Troubleshooting
If the system doesn't respond correctly when the sensor is acti-
vated, follow these guidelines:
• Check sensor programming (refer to the panel's program-
ming instructions) and reprogram the sensor if necessary.
• Move the sensor to another location and test for correct
response.
To relocate the sensor, do the following:
1.
Test the sensor a few inches from the original position.
2.
Increase the distance and retest until you find an acceptable
location.
3.
Mount the sensor in the new location.
If no location is acceptable, do the following:
1.
Test a known good sensor at the same location.
2.
If the system does not respond, avoid mounting a sensor at
that location.
3.
If the replacement sensor functions, return the problem
sensor for repair.
