To prevent the unnecessary turn out of the fire department for minor incidents a SPECIAL Alarm Concept was developed.
It involves operating personnel in the alarming sequence and relies on two operating states:
n“unmanned” mode Ü while the operating personnel is not present on the premises.
n“manned” mode Ü while the operating personnel is present on the premises.
“unmanned” mode
When the system operates in “unmanned” mode, the fire brigade is called immediately when an alarm signal is issued.
“manned” mode
When the system operates in “manned” mode, manual call points and automatic detectors trig- ger different actions in the event of an alarm:
