Transformers and AC Power Connection
The AC connection should be completed by a licensed electrician.
Never share the Fire Alarm Control Panel circuit with any other equipment.
The XR150FC/XR550FC panel comes supplied with a 16 Vac 56 VA transformer. The 16 Vac transformer must be wired
to a dedicated unswitched 120 Vac 60 Hz circuit with at least .87A available.
Always ground the panel before applying power to any devices!
Use 18 AWG or larger for all power
connections. The panel must be properly grounded before connecting any devices or applying power. Proper
grounding protects against Electrostatic Discharge (ESD) that can damage system components.
The 16 VAC
transformer must be
wired to a dedicated
unswitched 120 VAC
60 Hz circuit with at
least .87A available
