REPLACING A WIRELESS TRANSMITTER’S SENSOR BATTERIES

If any of the console’s zone indicators flash slowly, the wireless sensor trans- mitter or motion detector for that zone has not reported in during the last 4 hours. This is most likely caused by a dead battery in the wireless sensor transmitter or motion detector.

Replace the wireless sensor transmit- ter or motion detector’s battery, and then follow these steps to confirm that the console still recognizes it.

1.Set INSTALL/RUN 1/RUN 2 on the console to RUN 2.

2.Press TEST on the sensor or motion detector.

If the console chimes, it recognizes the sensor or motion detector.

If you do not hear a chime when you press TEST:

1.Set INSTALL/RUN 1/RUN 2 on the console to INSTALL.

2.Press TEST. The wireless sensor transmitter transmits a code to the console, and the console chimes to confirm it accepted the code.

The wireless sensor transmitter nor- mally is assigned to the same zone number as before you replaced the battery. However, if you replaced the

battery in the wireless sensor transmit- ter when its zone light was not flashing (low battery indicator), the wireless sensor transmitter is assigned to the next available zone.

To avoid this, remove the sensor’s old battery and wait at least 4 hours before installing the new one. This ensures that the sensor is assigned to its origi- nal zone number.

INTERCOM SYSTEMS

Intercom systems which send voice signals over existing electrical wiring might interfere with the ability to control modules from your security system when the intercom is in use.

If the intercom system has its own sep- arate wiring, it does not cause a prob- lem.
