To silence the Fire Brigade Panel buzzer, press the
SILENCE BUZZER
key (at the
MX1
panel or at the Remote FBP). The buzzer will be
Silenced. No other output or indication on the fire alarm panel will
change.
On a fire alarm the alarm devices (occupant warning system) will
generally be activated
– indicated by the red ALARM DEVICES
ACTIVATED LED on. Once the alarm is investigated and the building
occupants are permitted to re-enter the building, the alarm devices can
be silenced by pressing the
SILENCE/RESOUND ALARM
key. However,
if it is necessary to re-sound the alarm devices then press the
SILENCE/RESOUND ALARM
key again. This key will toggle the alarm
devices on and off while an alarm is present.
The Alarm Devices will automatically re-sound on a new alarm.
Note the Alarm Devices need to be silenced before the
RESET
or
DISABLE
keys can be used.
On a networked system the
MX1
may be configured to allow you to
silence/resound alarms on remote panels. Refer to Silencing Remote
Alarm Devices in Chapter 9.
Generally the alarm state latches with the
MX1
so that each alarm can be
viewed later when fire-fighting personnel arrive at the fire panel.
When the alarms have been investigated and are no longer required they
can be reset.
The condition that caused each alarm must be cleared before the zone
can be reset to the normal state (for example, smoke cleared from smoke
detectors, manual call point element restored to normal, latched
detectors or MCP in the field have been disabled).
If the LCD is showing the alarm list, i.e., the first alarm on the top 2 lines
and any subsequent alarm on the next two lines, pressing
RESET
will
reset all zones in the alarm list.
The display shows “Resetting Alarms…”,
and as each alarm is successfully reset, its entry in the list will disappear.
When the last zone is cleared, the alarm list display is cancelled.
Press
F1
for the first alarm or scroll the display with
NEXT
until the
required zone alarm is shown on the last 2 lines of the display. Then
press
F3
to select that zone.
