The fire detection control unit includes a comprehensive self-monitoring functional-
ity. When the control unit detects an error in the system (e.g. a detector is re-
moved), this is signaled as fault. Faults are normally transmitted to a receiving sta-
tion. Faults should always be remedied as quickly as possible.
The process with a fault depends on the set operating mode 'Manned' or 'Un-
manned' (see figure below).

Process in operating mode 'Unmanned'
The fault automatically activates the remote transmission for faults.
Process in operating mode 'Manned'
During V1 the staff may acknowledge the fault. The control unit will indicate the
fault until it has been remedied. When the fault is not acknowledged within V1, the
remote transmission function is activated.
Faults are possibly always immediately transmitted to the receiving station (see section 'Configura-
tion'.
