The power supply is located directly behind and below the main board. The ratings are:
Figure 18 Main Power Supply Connections
Electrical Input rating 120 VAC, 60Hz, 1.73A / 240VAC, 50Hz, 0.864A
Battery fuse on Main module 10A, slow blow micro fuse (not replaceable)
Caution: The main AC branch circuit connection for the Fire Alarm Control Unit must
provide a dedicated continuous power without any disconnect devices. Use
#12 AWG wire with 600-volt insulation and proper over-current circuit
protection that complies with the local codes. Refer to 16.0 Appendix C:
Specifications on page 62 for specifications.
Note: Ensure that the AC supply is disconnected before wiring the power to the panel.
Wire the AC power to the AC wiring terminals as shown in Figure 18 using the
proper wire gauge. Fire alarm systems must be installed in compliance with local
codes and standards and with the Authority Having Jurisdiction (AHJ)
Note: The FX-350 panel is capable of being wired for 120 VAC or 240 VAC 50/60 Hz
as shown above. A good ground connection to the “Ground" terminal is
essential to electrical safety, ensure proper operation, and specified noise
immunity.
