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.

2. Test the system after any alarm occurs (see

TESTING THE

SYSTEM

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 2Ð4 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:ÊÊUse only batteries recommended by your installer

as replacement.
