Siemens FP2005-A1 Auxiliary Power Supply (150W,B)

FP2005-A1 is a 150 W power supply kit that provides auxiliary power in tiered installations. It converts mains voltage to system voltage, monitors mains and battery status, and reports faults when problems occur. The B variant is preferred in buildings where multiple supply layers are used in series. It maintains siren and strobe line voltages at acceptable levels over long cable runs.
