The 865 is suitable for use with 2 or 4-wire circuits. The module also includes a Trouble LED, Ground Fault LED, and a set of Normally Closed Trouble contacts to indicate off normal conditions. Additionally, the module includes a Bell Silence switch for use during testing or service. Connect a maximum 5 Amp, 12 or 24 VDC regulated, power limited power supply listed for Fire Protective Signals to the module to support alarm power requirements beyond the panel alarm output capacity. Compatibility • XT30/XT50 Series panels • XR150/XR550 Series panels What is Included? • One 865 NAC Module • One Model 308 10k Ohm Resistor with Leads • Hardware Pack 1 MOUNT THE MODULE The module can be mounted in a DMP enclosure using the standard 3‑hole mounting pattern. Refer to Figure 2 as needed during installation. 1. Hold the plastic standoffs against the inside of the enclosure side wall. 2. Insert the included Phillips head screws from the outside of the enclosure into the standoffs. Tighten the screws. 3. Carefully snap the module onto the standoffs. WIRE THE MODULE 2 Caution: Disconnect all power from the panel before wiring the module. Failure to do so may result in equipment damage or personal injury. For power connections, use 22 AWG or larger wire. Refer to Figure 3 and Figure 4 when wiring the module. 1. Connect module Terminal 1 to panel Terminal 7. 2. Connect module Terminal 2 to panel Terminal 10. 3. Connect module Terminal 3 to panel Terminal 5. 4. Wire power supply positive to module Terminal 4. 5. Wire power supply negative to module Terminal 5. 6. If powering the NACs from the control panel, connect a jumper between module Terminals 3 and 4 and between Terminals 2 and 5. For supervised circuits, ground fault is detected at 0 (zero) Ohms. 7. For Style W connections, wire module Terminals 6-11 as shown in Figure 3. Install the included 10k Ohm EOL resistor across Bell Output A + and Bell Output A –. 8. For Style X connections, wire module Terminals 6-11 as shown in Figure 4. Trouble contacts are connected to a zone on the panel to indicate NAC trouble or ground faults. The common relay is rated 30 VDC @ 1 Amp, resistive. 9. For Style W and Style X circuits, install a jumper on the Bell Ground Header. The jumper also disables the alarm bell output in the event of a ground fault on either side of the notification circuit.
