MAINTAINING YOUR SYSTEM
of Your System
The components of your security system are designed to be as free of maintenance as
possible. However, there are some things you can do to make sure that your system is in
reliable working condition.
1. Test your system weekly.
2. Test the system after any alarm occurs (see
TESTING THE SYSTEM
Replacing Batteries in
Wireless sensors may
not have been used in
your security system
Each wireless sensor in your system has a 9-volt or a 3-volt battery. The system detects a
low battery in any wireless sensor, including smoke detectors, the optional personal
emergency transmitter, and the optional portable wireless keypad. A low battery in a
portable wireless keypad is detected as soon as one of its keys is pressed, and the wired
keypad will display 64.
Alkaline batteries provide a minimum of 1 year of operation, and in most units and
applications, provide 2–4 years of service (4–7 years in units using 3-volt lithium batteries).
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 or large swings in temperature, may all
lead to the reduction of actual battery life in an installation.
If you have a low battery in a wireless sensor, a low battery message is dis-
played on the keypads.
In addition, a battery-operated smoke detector with a low battery also emits a single "chirp"
sound once approximately every 20-30 seconds, identifying itself as the smoke detector
with the weak battery. If you do not replace a smoke detector's low battery, the smoke
detector may sound continuously, as if there were a fire alarm.
The low battery message comes on as a warning that battery replacement in
indicated sensor(s) is due within 30 days. In the meantime, the sensor(s) causing the low
battery indication are still fully operational.
Important: Use only batteries recommended by your installer as replacement.
