22 Power supply

22.1Concept

The power supply for the FC700A fire detection system consists of:

Converter	(mains voltage -> system voltage 29,6V)
Battery charging unit	(by means of E3C011)
Batteries (lead)	(capacity as required)

22.2Special functions

–Automatic battery load test

–Battery charging characteristic can be programmed according to make

22.3Application

–Determine required battery capacity individually -> see chapter 23

–Max. 27Ah per battery charging unit (> 27Ah = auxiliary power supply)

–Parallel operation of several battery charging units possible

–Battery lead without EMI-protection (battery cannot be mounted separately)
