SILENCING ALARM, SUPERVISORY AND
TROUBLE EVENTS
The two Indicating Circuits at the Main Control Panel and
Remote Hazard Units provide Audio-Visual warnings of the
various Alarm conditions that may occur on the System.
All units are also provided a Buzzer to indicate the opera-
tion of Supervisory and Trouble events.
2-6.1
Silencing Alarms
As described in Paragraph 1-4.4.4, the two Indicating Cir-
cuits can be programmed to operate independently and
generate a variety of tones depending on the Alarm condi-
tion. Since both circuits can also be programmed to oper-
ate either in Silenceable or Non-Silenceable mode, their
silencing also follows the same logic:
To silence an Alarm from anywhere in the System, press
the SIGNAL SILENCE button on the MCP. The LCD dis-
play will show the status of the MCP and will prompt the
user to select the unit (i.e. MCP or RHU) to be silenced.
Use the up/down cursor keys to scroll through all the units
to the one required:

Also since one circuit is still active, the System will remain
in an 'un-silenced' condition i.e., the 'Silenced LED' will not
be illuminated and the buzzer will still be steady.
2-6.2
Silencing a Supervisory or Trouble Event
The sequence for silencing Supervisory and Trouble events
is very similar except that the signal circuits are not acti-
vated during a Supervisory or Trouble condition.
If an RHU has both active troubles and alarms that have
not been silenced both will be "silenced" by the one opera-
tion of the "silence" sequence of that RHU.
2-6.3
Non-Silenceable Event
Waterflow activations cannot be silenced. These alarms
latch the indicating outputs and buzzer in the steady state
mode.
2-6.4
Resound
Once a Supervisory or Trouble is silenced, it will sound again
if the condition continues to exist after 24 hours. Further-
more, the buzzer sounds follow the same rules for global
and local mode: the Main Control Panel is configured for
global mode and annunciates all alarms anywhere in the
system. A Remote Hazard Unit configured for local mode
annunciates only alarms originating in its own hazard.

LED INDICATORS
The LED (low-current light emiting diodes) indicators on
the front of the unit can be easily observed by the user to
provide further signal of an alarm, supervisory or trouble
condition in the system. There is also a POWER ON indi-
cator to indicate AC power and a SIGNAL SILENCED indi-
cator to indicate that all alarm and trouble messages in the
unit were acknowledged with the SIGNAL SILENCE but-
ton.
If the Main Control Panel and Remote Hazard Unit are set
for global mode, the indicators display global conditions.
Otherwise, the indicators display local conditions (setting
global and local mode is described in Paragraph 2-3).
