4.3.3 Alarm Indication

If an alarm occurs, the red ALM beacon will flash together with the alarm number, for example AL1. If more than one alarm is present each alarm number is flashed in turn. Any output (usually a relay) attached to an alarm will operate.

 

An alarm relay can be configured, using the ‘P’ codes P11 to P14, to be energised or de-energised in the alarm condition. It is normal to configure the relay to be de-energised in alarm so that an alarm is indicated if power to the controller fails.
