Fault state

28. 1

Introduction

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 28.2).
• Closes the Fault Status NO output contacts. These
status output contact is opened again when the fault
is reset (see section 28.3).
• Lights a fault indicator on the front panels that
indicates the source of the fault (see section 28.4).
The indicator is switched off when the fault is reset
(see section 28.3).

28.2 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 (see figure
28.1). The fault state can also be acknowledged by
pushing the Fault Acknowledge button on the fireman's
panel.

28.3 Reset the fault state

Reset the fault state by pushing the Fault Reset button
on the front of the voice alarm controller or the remote
controls (see figure 28.2). The fault state can also be
reset by pushing the Fault Reset button on the fireman's
panel. In order to reset the fault state, it first must be
acknowledged (see section 28.2). 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.

28.4 Fault indicators

The voice alarm controller, voice alarm router and
remote controls have two types of fault indicators:
system fault indicators (see figure 28.3) and loudspeaker
line fault indicators (see figure 28.4). The system fault
indicators provide information about failing system
functions that are supervised (see table 28.1). If a system
fault is persistent, contact your dealer.
