Drukuj stronęIf evacuation is necessary, it can be signalled by pressing the Sirens On key on the operating
panel or by activating one of the alarm pushbuttons (which are distributed throughout the
building).
If the operating panel is not operated within this time (T2), the alarm devices will be activated
automatically. The alarm devices will remain activated for the siren operating time, T3. See time
diagram b: operator presses Buzzer Stop, Inspection Walk starts, the operator does not come
back in time and the alarm devices are activated automatically.
If evacuation is not necessary but the alarms that are already on the operating panel need to
remain there (optical indications), press the Buzzer Stop key again. See time diagram c:
operator presses Buzzer Stop, Inspection Walk starts, the operator comes back in time. The
alarm devices will not be activated and all messages that were on the operating panel will stay
there. The fire alarm control panel will be in monitoring mode, however. If a new alarm condition
occurs, the control panel will activate all alarm devices immediately.
If evacuation is found not to be necessary because the cause of the alarm is known but has
gone away in the meantime, the Reset key on the operating panel can be pressed. The control
panel will return to its normal state. If an alarm pushbutton is pressed again or a fire detector
remains in an alarm state, the control panel will return to the alarm state within a few seconds.
Note: if 0 minutes 0 seconds is entered for:
- T1: there is no Operator Response Time. All alarm devices will always be activated
immediately in this case. If that is what is actually wanted, it is better to place the control panel in
the night scheme.
- T2: there is no Inspection Walk Time. If in the case of an alarm the Buzzer Stop key on the
operating panel is pressed within the Operator Response Time, the Inspection Walk Time will
NOT be started. This means that the alarm devices will no longer be activated automatically as a
result of an alarm condition. The fire alarm control panel will be in monitoring mode, however. If
a new alarm condition occurs, the control panel will activate all alarm devices immediately.
- T3: the alarm devices will not be switched off automatically. All alarm devices will then continue
to operate until they are stopped from the operating panel.
Times T1 and T2 can be set to a maximum of 9 minutes.
In order to comply with EN54-2 Item 7.11.d it is necessary to install at least one pushbutton that
can activate the alarm devices without delay, even if delays are active at the time.
