Replacing A Wireless Sensor Transmitter's Batteries; Intercom Systems - Radio Shack 49-2551A Owner's Manual

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

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
console to
INSTALL
2. Press . The wireless sensor
TEST
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
38
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
on the 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.
