Distribute the alarm message
Distributing the default alarm message is similar to distributing the default alert message (see
section Distribute the alert message, page 94). Push the Alarm message button instead of the
Alert message button. The alarm message can also be distributed by pushing the Alarm
Message button on the fireman’s panel.

Fault State
If a supervised function fails, the system enters the fault state and:
– Starts a beeper. The beeper is switched off when the fault is acknowledged (see section
Acknowledge the fault state, page 96).
– Closes the Fault Status NO output contacts. These status output contact is opened again
when the fault is reset (see section Reset the fault state, page 97).
– Lights a fault indicator on the front panels that indicates the source of the fault (see Fault
indicators, page 98). The indicator is switched off when the fault is reset (see section
Reset the fault state, page 97).
Acknowledge the fault state
The beeper can be switched off by acknowledging the fault state with the Fault Ack button on
the front of the voice alarm controller or the remote controls. The fault state can also be
acknowledged by pushing the Fault Acknowledge button on the fireman’s panel.
