Alarm concept

24 Alarm concept

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

24.1Cerberus Alarm Concept (CAC)

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

24.2Principle of the Cerberus alarm concept

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"
