2. Enter the security code then press test key.
3. Listen. The external sounder should sound for 2 seconds and then turn off. If the sounder does not sound, call
for service immediately.
4. Open each protected door and window in turn and listen for three beeps from the keypad. Identification of each
faulted protection point should appear on the display. The display will clear when the door or window is closed.
Walk in front of any interior motion detectors (if used) and listen for three beeps. The identification of the
detector should appear on the display when it is activated. The display will clear when no motion is detected.
Note that if wireless motion detectors are used, there is a 3-minute delay between activations. This is to
conserve battery life.
To test all smoke detectors, follow the manufacturer's instructions. The identification of each detector should
appear on the display when each is activated. If a problem is experienced with any protection point (no
confirming sounds, no display), call for service immediately.
When all protection points have been checked and are intact (closed), there should be no zone identification
numbers displayed on the keypad. When testing is completed, exit the TEST mode by continuing with step 5.
5. Enter your security code and press the OFF key. If the test mode is inadvertently left active, it automatically
turns off after 4 hours.
Other System Information
Common Zone Operation
Your system may have been set up to use a common zone, which is an area shared by users of both partitions, such as a
foyer or lobby. If so, please note the following:
The common zone will sound and report alarms only when both partitions are armed. If only one partition is
armed, the system ignores faults on the common zone.
Either partition may arm its system if the common zone is faulted, but once armed, the other partition will not
be able to arm unless the common zone is first bypassed or the fault is corrected.
Faults on the common zone are displayed on keypads in both partitions.
Either partition can clear and restore the common zone after an alarm.
Maintaining Your System
Replacing Batteries in Wireless Sensors
Note: 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 wired
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. 3-volt lithium batteries provide up to 4 or more 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 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.
