The alarm concept must be worked out individually for each system
The important thing is to pass on the alarm message quickly to the appropriate
group of recipients
The requirements vary between
'Discreet alerting' of the reconnaissance squad, e.g. via staff paging system
–
'Alarm / evacuation' for people familiar with the location
–
'Alarm / evacuation' for people unfamiliar with the location
–
'Area evacuation', e.g. building storey
–
The Cerberus alarm concept prevents the unnecessary turnout of the fire de-
partment for minor incidents
The CAC is based on an alarm organization involving the presence or absence
of personnel:
Presence of operating personnel or "Day"
–
Absence of operating personnel or "Night"
–
The response of the operating personnel is monitored by two independent time
circuits (V1 and V2) monitored
The CAC is an integrated part of the FC700A control unit. The required parame-
ters can be entered via the user functions
During the "Day" operating mode, if an alarm is activated its source is located
–
and the decision is taken "Emergency" or "Minor incident"
During "Night" operating mode, all signals immediately generate a "Remote
–
alarm"
The activation of a manual call point always immediately generates a "Remote
–
alarm"
