The alarm devices will automatically re-sound if a new alarm occurs. To
re-sound silenced alarm devices manually, press SILENCE/RESOUND
ALARM again.
5. Reset the alarm(s)
.
Press RESET to attempt to clear all alarms.
Refer to “Resetting Alarms” on page 2-6.
6. Wait
at least one minute to ensure all alarm conditions have cleared.
If an alarm reappears investigate further, and if a detector will still not
reset, if possible determine the cause, e.g., the detector is faulty, insect
infested, or excessively dirty, or there is lingering smoke from a minor fire
event. Note that manual call points (MCPs) that have been operated will
need to have the frangible element replaced before they can be reset. If
the source of alarm cannot be cleared, then disable the alarm (see next
step).
7. Disable the alarm(s). Press DISABLE to disable the alarms. This
will disable zones and/or points in alarm depending on the system
configuration. If alarms remain in the list after the Disable operation is
complete, press
RESET to clear the alarm list. The Disables indicator
will be lit. Re-enabling zones and points that have been disabled
requires use of keys outside the f.b.p. Refer to Chapter 3 for details.
8. Log the event. Enter the alarm details in the log book. Advise the
building owner or their representative.
When the first alarm condition is detected by the MX1 , it does the
following to indicate the presence of the alarm:

The red general Fire indicators light red and individual Zone Alarm
indicators (if fitted) flash red.

The buzzer pulses.

The Fire Brigade alarm routing output is activated, shown by the red
ALARM ROUTING ACTIVATED indicator.

The Alarm devices are activated, shown by the red ALARM DEVICES
ACTIVATED indicator.

Other outputs, e.g. smoke control, air-conditioning shutdown, door
holder releases, etc., may be activated to control the fire situation.
The LCD will show the first alarm on the top two lines and, if present,
subsequent alarms on the lower two lines.
