Silent Alarm
Any fire alarm signal will be indicated at the panel without any delay,
and this is the Silent Alarm level. An output may be configured to be
activated at this level, as an example to trigger a coded message
through a voice alarm system or an output to make on site technical
personnel aware of the situation.
The delay timer T1 will be started and a countdown timer will be
shown in the display. For a Delayed detection zone the operator
may now initiate a prolonged T2 period.
Small Alarm
In the case of a Delayed Dependency detection zone there is an
automatic transfer from the initial T1 delay period to the prolonged
T2 delay period. When this transfer occurs the level will be
increased to Small Alarm. Looking at a shopping centre this level
may be used for another voice alarm message making the
employees start the preparations for an evacuation. The display will
show the T2 countdown.
(Small alarm level is also shown for Delayed and Dependency
zones, but should not be used as an activation criteria for outputs.)
Large Alarm
The table below shows that this level is the last one (or only) for all
types of detection zones. There are different ways of getting to this
level, either elapsed timers (T1 and/or T2), a second alarm signal or
a panel operation. If not configured otherwise, all outputs will be
activated at this level, fire brigade (FARE), sounders (FAD) and any
other outputs (FPE).
