2.5.2 Power Supply Module & Transformer (FCI-PSM)
The Power Supply Module & Transformer (FCI-PSM) is equipped with a built-in battery charger that can
charge batteries up to 17-AH capacity. The remote-amplifier cabinet can house two 17-AH batteries. Primary AC
power is monitored by the FCI-PSM. The AC loss relay contacts change state and the “AC ON” LED
extinguishes upon loss of AC power or brown-out. Switch S1 is used to select immediate or 6 hour delay
of AC loss relay transfer.
The Model FVXFMR is used for 120 VAC input, while the Model FVXFMR 220 is used for 240 VAC input.
