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"
