2.9.3 Backup Alarm
The Back-up Alarm is a hard-wired link from each Detector installed on the system. This facility will
allow any Detector which is in a fault condition and sees an oil mist level of 1.6mg/I or greater to produce
the Common Alarm Relay in the Control Panel, the Backup Alarm will also override any Detector or
Detectors that are isolated.
Whilst any Detectors are in a Backup Alarm condition the Accept key is inoperative until the oil mist level
drops below 1.6mg/l.
It is possible for a healthy Detector to produce a backup alarm if the level of oil rises very rapidly.
To check the integrity of the Backup Alarm signal between the Control Panel and the Detector a Backup
Alarm Test should be performed.
1. From the Test Menu, Figure 62, select 5. Backup Alarm
