DMP Electronics XR2500F AC Connection, Transformers and AC Power Connection, VAC Transformer

Introduction

AC Connection

3.1Transformers 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 XR2500F comes supplied with a 16 VAC 56 VA transformer. The 16 VAC transformer white leads and black leads must be connected to an unswitched 120 VAC 60 Hz power source with at least .87A available. Observe wire colors and connect the transformer wires:

The Black transformer wires to the Black 120 VAC wire The White transformer wires to the White 120 VAC wire The Green/Yellow ground wire to the electrical ground

Always ground the panel before applying power to any devices! Use 18 AWG or larger for all power connections. The XR2500F must be properly grounded before connecting any devices or applying power to the panel. Proper grounding protects against Electrostatic Discharge (ESD) that can damage system components.

3.216 VAC Transformer

The 16 VAC 56 VA transformer supplies power to the XR2500F panel and is factory pre-wired. See Figure 3: Transformers and AC Power Connection. Also refer to Figure 11: XR2500F Panel Wiring Diagram.

3.3Earth Ground (GND)

The XR2500F terminal 4 must be connected to earth ground using 14 AWG or larger wire to provide proper transient suppression. DMP recommends connecting to a cold water pipe, building ground, or ground rod only. Do not connect to an electrical ground or conduit, sprinkler or gas pipes, or to a telephone company ground.
