Delayed alarm is automatically reset, see chapter “Alarm Reset”, page 58.
Note: The delayed alarm function for a conventional Zone Line Input e.g. 3361 Input 0
(Z), zone expansion board 4580 inputs is different. The “Delayed alarm” check box in the
Zone Line Input properties is called “AVF”, the general delayed alarm function will not be
used and is replaced by the alarm verification function.
14.6.2
Alarm Delay Facility (ADF)
The ADF is a new optional function added in the AS1670.1:2015. The function is similar to
the Alarm Acknowledgement Facility (AAF) without manual acknowledgement button (LAA
or AAM). Instead of the manual control, the function will be automatically control by a time
delay that can be set in the system properties.
In this specific application, the alarm activation type for an output unit (3379) must be set
(in EBLWin) to “DelayedAlarmZoneAddress” (or zone). In this case, when the alarm point
(only analogue smoke or multi detectors) activates an alarm, the output unit 3379 will
sound for the predetermined time delay period without signalling alarm to the FDCIE. If the
alarm point remains in alarm after the time delay elapsed, a general fire alarm in the FDCIE
will be generated. If the smoke cleared form the smoke detector before the end of the time
delay period, the alarm will automatically reset and the system remains in the normal
condition. The delay for this application can be selected in EBLWin system properties for
up to 255 seconds.
Application Example:
A typical application for the ADF would be a residential accommodation where false alarms
may cause a brigade call. A sounder base(s) 3379 is used as a local warning, it is mounted
inside the apartment and will activate upon receiving an alarm from a smoke detector
inside the unit and continues to operate for the time delay configured in the system
properties (0-255 sec). If the smoke has not been cleared from the smoke detector during
the time delay, the control panel will generate a general fire alarm. If the smoke clears up
within the delay time, the alarm will automatically reset, 3379 will be silenced and the
system restores to the normal condition.
Several control expressions are available to cover any possible configuration:
•
DelayedAlarmZoneAddress (Zone, Address), true when a certain zone / address
is in delayed alarm state.
•
DelayedAlarmZone (Zone), true when a certain zone or any detector in a certain
zone is in delayed alarm state.
•
GeneralDelayedAlarm, true when any zone or zone/address is in delayed alarm
state.
14.7
Alarm Acknowledgement Facility (AAF)
One or more Local Alarm Acknowledgement Unit (LAAU or discontinued AAM) can be
used in the system.
The LAAF is a function requires wall mounted Local Alarm Acknowledgement Unit (LAAU)
4445 or the Brooks discontinued Alarm Acknowledgement Module (AAM) 3340. The LAAU
is used in residential applications to provide the occupant with a local control facility to
control nuisance alarms within the occupancy e.g. cooking fumes, smoking, aerosol spray,
steams, etc. and prevent this nuisance alarm from generating general fire alarm within the
building. It provides the occupant inside the sole occupancy unit with a pre-determined
time to acknowledge a nuisance alarm and investigation time to clear the smoke from the
smoke chamber in the active unit.
A complete AAF requires an LAAU (AAM), one or more sounder base 3379 and up to 5
analogue smoke detectors (sensors). Each AAF unit configured as an AAF zone.
See FT128 Technical Manual chapter "Alarm Acknowledgement Facility (AAF)" for more
information.
