Maintaining Your System
Taking Care 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. (See
TESTING THE SYSTEM
and
FIRE ALARM
SYSTEM
sections).
2. Test the system after any alarm occurs.
Replacing Batteries in Wireless Sensors
Wireless sensors
may not have
been used in your
security system
Each wireless sensor in your system has a 9-volt or 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 keypad will display
00
.)
Alkaline batteries provide a minimum of 1 year of operation, and in most units and
applications, provide 2–4 years of service. 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
displayed on the keypad.
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.
NOTE:
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 is still fully operational.
IMPORTANT:
Use only batteries recommended by your installer as replacement.
