Removing the PIR Circuit Board
5.
Remove the PIR circuit board battery (located on
opposite side of components) and install a new one,
observing polarity (marked on the circuit board).
6.
Re-install the PIR circuit board into the sensor plastic.
7.
Re-install the transmitter circuit board onto the PIR
circuit board.
8.
Install a new battery in the transmitter circuit board,
observing polarity (marked in battery bucket).
After replacing batteries, wait at least 3 minutes before
activating the walk test mode.

Lithium Battery Disposal
Lithium batteries that are no longer usable are considered
hazardous waste. Be sure to properly dispose of the old
batteries. Contact your local city government for hazardous
waste disposal laws.
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.
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.
