recommended the alarm buzzer be left on to remind operators that the
alarm must be reset otherwise the fire brigade will be called.
Investigate the zone and area where the point in alarm is located.
If no source of fire can be detected, or the cause is identified and does
not require fire brigade attendance, reset the alarm by pressing
RESET
and then
OK
(see page 2-6). The alarm will be reset and the AIF timers
cleared. If the cause of the alarm is still present, the zone will go into
alarm again.
If the alarm is not acknowledged, or is not reset by the end of the
programmed investigation time (default 5 minutes) or another alarm
occurs, then the AIF delay is cancelled and the alarm(s) are treated as
ordinary alarms.
Note that pressing
DISABLE
from this display will not allow the alarm to
be disabled.
In some situations where nuisance smoke alarms are likely, the Alarm
Acknowledgement Facility (or Alarm Delay Facility) may be used to allow
the occupant to acknowledge (AAF only) the alarm locally and then have
time to clear the smoke before the alarm is fully recognised and is
signalled to the fire brigade, etc.
By default, these alarms are not indicated on the
MX1
until the alarm is
fully recognised. In some situations, where suitably trained operators are
handling alarms on the
MX1
, the initial smoke detector alarm can be
indicated on the FBP display. In this case the initial alarm is shown as a
standard alarm, except that the Alarm Type is shown as AAF (or ADF)
and the Fire Indicator, Alarm Devices and Alarm Routing are not
activated. If the alarm is cleared by the occupant before the fire brigade
is signalled, the alarm is automatically cleared from the
MX1
.
If the alarm becomes fully recognised, the initial alarm indication is
replaced with a new alarm event and treated as usual.
Other alarm types, such as sprinkler systems, pump run status, etc.
may be connected to the
MX1
and displayed in a number of ways.
For example, sprinkler alarms may be annunciated as for any other alarm
in the system, i.e., shown in the Alarm List and activate Alarm Routing
and Alarm Devices. As such, these alarms may be viewed in the same
way as any other alarm, but resetting of the alarm may not be successful
until the sprinkler water flow has been stopped.
