Maintaining your system
The components of your security system are designed to be as maintenance-free as
possible. To make sure that your system is in working condition, do the following:
1. Test your system weekly.
2. Test your system after any alarm occurs (see the TESTING THE SYSTEM section).
Low Battery Conditions in Wireless Sensors
Each wireless sensor in your system has a 9-volt or 3-volt battery. The system detects low
battery conditions in wireless sensors, including smoke detectors, personal emergency
transmitter, and the portable wireless keypad, and displays a "LOW BAT" message on the
master keypad, which also beeps. (A low battery in a wireless keypad is detected as soon
as one of its keys is pressed, and the master keypad will display "00."). In addition, a
wireless smoke detector with a low battery also emits a "chirp" sound approximately once
every 20–30 seconds, identifying itself as the smoke detector with the weak battery.
NOTE: A low battery message means that battery replacement in the indicated sensor(s)
is due within 30 days. In the meantime, a sensor with a low battery is still operational.
Silencing Low Battery Warning Tones at the Keypad: Press the OFF key.
The low battery message display will remain on as a reminder. When you replace the
weak battery with a fresh one, the sensor will send a "good battery" signal to the control
when the sensor is activated (opening/closing of door, window, etc.). To clear the "LOW
BAT" display, enter your code + OFF.
When replacing batteries, use only those recommended by your installer.
Alkaline batteries provide a minimum of 1 year of operation, and in most units and applications, provide 2–4
years of service. 3-volt lithium batteries may provide from 4-7 years of operation. Actual battery life will
depend on the environment in which the sensor is used, the number of signals that the transmitter in the sensor
has had to send, and the specific type of sensor. Factors such as humidity, high or low temperatures, and large
swings in temperature may all lead to the reduction of actual battery life in an installation.
Changing the System Battery
In the event of an AC power loss, the system is
powered by a non-rechargeable, alkaline battery,

Slide out the battery drawer. Remove the old
battery and replace with a fresh battery. Carefully
slide the drawer back into the master keypad.
The "LOW BAT" display should clear
automatically within 4 hours.
