Fire Safety
A fire detection installation is ready for operation when the fire control panel is
supplied with energy and no other operation condition is indicated.
As soon as an event occurs in the ↑ 'Station' which deviates from operational
readiness, this event is indicated and the 'Station' changes to the condition
corresponding to the type of event.
'Station' may be in several conditions simultaneously:
● 'ALARM' (fire detection condition)
● 'FAULT' (fault message condition)
● 'ISOLATION' (isolation condition)
● 'DETECTOR TEST' (test status)
● ↑ Normal operation (operational readiness)
Indication of the operating condition
● The operating condition is indicated on the ↑ PMI:
– Visually and acoustically by LEDs, buzzers and on the display.
The fire detection installation has the following operation modes:
● ↑ Normal operation
– 'Manned operation'
– 'Unmanned operation'
● Test
● 'Isolation'
– ' --Renovation mode'
In ↑ normal operation 'ALARMS' are evaluated and processed in accordance with
the 'Manned operation' or 'Unmanned operation' operation mode.
↑ Normal operation is described in the following:
● The detectors are set to normal sensitivity level, in accordance with the
relevant ↑ parameter set.
● The fire detection installation is ready to receive danger messages ('ALARMS')
and fault messages.
● The 'System On' LED lights up.
In normal operation, the fire detection installation may be in the 'Manned operation'
or 'Unmanned operation' operation mode. In the 'Manned operation' operation
mode, the 'Premises manned' LED is on.
'Manned operation'
In the 'Manned operation' operation mode, events can be processed via ↑ 'AVC' or
↑ 'IC'.
The remote transmission of an 'ALARM' may be delayed, for example, and an
operator may verify 'ALARMS' or 'Faults' that have occurred.
'Unmanned operation'
In the 'Unmanned operation' operation mode, events are directly handled in
accordance with the configuration, without taking into account the 'AVC' or 'IC'.
This means e.g. that remote transmission of an 'ALARM' is effected without delay.
Global alarming is activated immediately.
