Concept
The power supply for the CS1140 fire detection system consists of:
Converter
Battery charging unit
Batteries (lead)
Special functions
automatic battery load test
Battery charging characteristic can be programmed according to make
Application
Determine required battery capacity individually Õ
Protection of mains lead only in special cases Õ
max. 42Ah per battery charging unit ( > 42Ah = auxiliary power supply)
Parallel operation of several battery charging units possible
Battery lead without EMI-protection (battery cannot be mounted separately)
Õ Battery charging unit is integrated in the E3X10. master module
CC11
Õ Battery charging module E3C011 required
