5.6.7 Distribute the alarm message
Distributing the default alarm message is similar to

Alarm message
button instead of the

message button (see figure 5.19).
5.7 Fault state
5.7.1 Introduction
If a supervised function fails, the voice alarm controller
enters the fault state and:
•
Starts a beeper. The beeper is switched off when the
fault is acknowledged (see section 5.7.2).
• Closes the Fault Status NO output contact. This
status output contact is opened again when the fault
is reset (see section 5.7.3).
• Lights a fault indicator on the front panel that
indicates the source of the fault (see section 5.7.4).
The indicator is switched off when the fault is reset
(see section 5.7.3).
5.7.2 Acknowledge the fault state
The beeper can be switched off by acknowledging the
fault state with the
Fault Ack button (see figure 5.20).
The following buttons also acknowledge the fault state
and stop the beeper:
•
Alert button
•
Alarm
button
• PTT button of the emergency microphone
5.7.3 Reset the fault state
Reset the fault state by pushing the Fault Reset button
(see figure 5.21). In order to reset the fault state, it first
must be acknowledged (see section 5.7.2). When the
Fault Reset
button is pushed, the fault indicators are
switched off and the status of the system is checked.
•
If the fault is not resolved, the fault indicators are
switched on again. The beeper remains off. It is only
switched on if a new fault occurs or if the resolved
fault occurs again.
• If the fault is resolved, the fault indicators remain off.
