9.1 General
The fire detection installation requires only little maintenance work. It has a high
degree of self monitoring, such as
 detectors monitored on presence, lines on wire break and short circuit
 call points monitored on broken glass, lines on wire break and short circuit
 control lines monitored on wire break and short circuit
 battery monitored on presence and capacity
 permanent system checking by watchdog function
 programmed user functions are stored in FLASH-memory
