3.17 Alarm Handling - A Typical Situation
The handling of a fire situation will typically contain the following
phases:
One or more detection zones are issuing Prealarm signals
(Accept).
One or more of these detection zones will go into Fire Alarm,
activating Fire Alarm Devices (FAD) and Fire Protection Equipment
(FPE).
When the operator has investigated the cause of the alarm, the
activated Fire Alarm Devices (FAD) may be deactivated when the
situation is under control (Silence Alarms).
If the deactivation of the Fire Alarm Devices (FAD) shows to be
erroneous, the Fire Alarm Devices (FAD) may be resounded
(Resound).
After silencing the Fire Alarm Devices (FAD), the system may be
reset. Reset will delete all indications of the fire situation and, if
physically possible, deactivate the Fire Protection Equipment
(FPE) (Reset).
The reset operation includes alarm disabling of all those points
within the operation zone of the operating panel still signalling Fire
Alarm (must be confirmed by the operator). Alarm disabling may
later be cancelled and the points made to retransmit their alarm
level (Reactivate).
