8. ALARM MANAGEMENT
When an Alarm is triggered, action is taken on devices, where this option is provided for, and the LED, remote
relay and relevant screens are all activated at the same time.
To view the alarm triggered, simply press the Alarm key - you can then use the UP/DOWN keys to scroll
through the list and view other alarms that might have been triggered. To reset Alarms in the log, you must
call up the alarm screens and press the ALARM key again.
An alarm history is always available where the 150 last alarms are stored. It is possible to reset this history
via the maintenance menu. When the clock board is present, the hour and date of appearance of each alarm
are also stored.
