Fire Safety
Should an event ('Pre-ALARM', 'ALARM') arise, the operating personnel may
acknowledge presence within the time t1. After acknowledgement, the investigation
time t2 starts. If presence is not acknowledged within the given time t1, ↑ global
alarming is activated.
During the investigation time t2 the operating personnel may examine the indicated
source of alarm and check the cause of the 'ALARM':
Or is it a real fire (emergency)?
Is it a smoldering waste-paper basket (minor incident)?
Has the ↑ site detected a deceptive phenomenon (false alarm)?
In the event of a major incident (emergency), the nearest 'Manual call points' or
<Alarm delay off> must be pressed. ''Immediate global alarming'' is then triggered.
In the case of a ↑ minor incident or ↑ false alarm the operator may reset the
'ALARM' and cancel alarming.
If the 'ALARM' is not reset within the given time t2, 'Immediate global alarming' is
activated.
Alarm verification proceeds as follows:
An alarm event activates ↑ local alarming and starts the time t1 for attendance
check.
Operating personnel acknowledge 'ALARM' on the operating terminal prior to
the expiry of t1. Acknowledging normally silences local alarming (configurable
feature).
If there is no acknowledgment, ↑ global alarming is activated after the expiry of t1.
After acknowledgement, the investigation time t2 starts. During time t2
operating personnel investigate the fire location.
In the case of a minor incident the operator resets the 'ALARM' at the
nearest operating terminal. The alarming process stops, and no ↑ global
alarming is activated.
In the event of a fire, the nearest 'Manual call points' or <Alarm delay off>
must be pressed. 'Immediate global alarming' is triggered.
If there is no reset, 'Immediate global alarming' is also activated after the expiry of
t2.
