TESTING AND MAINTENANCE

Bell Test

Entering this command will sound the siren and turn ON all the keypad lights for 2 seconds. To perform a

bell test, enter [ ][4] on the keypad.

Weekly Testing

It is recommended that you test your system weekly.

1 Disarm the system and ensure that the "Ready" light is ON.

2 Perform a Bell Test by entering [ ][4]. The bell or siren will sound for 2 seconds and all of the lights

on the keypad will come ON.

3 Activate each sensor on your system in turn. For example, open protected doors and windows, and

walk in areas protected by motion detectors. Each Zone Light should come ON when each zone is

activated. Each Zone Light will be shut OFF when the zone is restored to normal (when the door or

window is shut, or when motion stops in areas protected by motion detectors).

4 If they are programmed for operation, press the [F], [A], and [P] keys in turn. The [F] key will sound the

bell or siren in a pulsed mode. Enter an Access Code to silence the alarm. The [A] key is a silent

alarm; the [P] key may be programmed as silent or audible. If an alarm sounds, enter an Access Code

to silence the alarm.

5 Should the system fail to operate properly, call your alarm dealer for service.

Maintenance

With normal use, your system requires a minimum of maintenance. The following points should be

observed:

1 Do not wash the keypad with a wet cloth, and do not use household cleaners, such as glass cleaners,

on the keypad. Light dusting with a cloth slightly dampened with plain water should remove normal

accumulations of dust.

2 For other system devices such as passive infrared, ultrasonic or microwave motion detectors,

glassbreak detectors and so on, consult the manufacturer's literature for testing, cleaning and

maintenance instructions.

3 It is recommended that the back-up battery be replaced every three years. Contact your installing

company for information on replacing the battery.
