Honeywell Esser 2 Series User Manual

Extinguishing Control Computer 8010 - Series 2
94 FB 798352 / 11.07
17.3 Power supply unit board and relay board
The combined power supply unit and relay board provides the entire voltage supply as well as the switching
outputs for control and status functions of the Extinguishing Control Computer. An increased current
requirement e.g. as a result of longer cable lengths, must be compensated for if necessary by an external
voltage supply via a separate power supply unit.
Constantly monitored conditions:
• Mains failure
• Battery charge
• Battery charging, current limited
• Earth fault identification (insulation)
