Audible/Visual Warning

When an intrusion is detected, the Alarm Sounder (Z171) will sound and visual indicators will flash. The output from the sounder is either pulsed or a continuous tone, depending on market legislation. If the output is pulsed, then its status will be synchronized with that of the visual indicators.

The lamps used for external visual indication are dependent upon market legislation, but will be either Hazards, or Side and Tail, or Dip and Tail.

Two different types of Alarm Sounders are available:
1. Normal Alarm Klaxon (Alarm Sounder (Z171))
2. Battery Backed Up Alarm Sounder (Z272)

The Battery Backed Up Alarm Sounder (Z272) is an alarm sounder which contains its own internal battery. When the ignition is on, the internal battery is charged via an ignition feed. If either the connector is removed or the wires to it are cut, then the sounder will sound for 4.5 minutes.

To disconnect the Battery Backed Up Alarm Sounder (Z272):
^ Turn Ignition On (Pos. II).
^ Turn Ignition Off.
^ Disconnect within 17 seconds.

To silence if triggered:
^ Connect.
^ Disarm Alarm.
^ Turn Ignition On (Pos. II).
