Adding a receiver makes these control panels compatible with NX wireless transmitters. Only three wire connections are required for power and communication to the control panel. Internal mounting For internal mounting, mount the receiver inside the control panel enclosure. Use the following installation guidelines: • Leave at least 10 in. (25 cm) above the control panel for the receiver’s antennas. • Avoid areas that expose the receiver to moisture. • Avoid areas with excessive metal or electrical wiring, including furnaces and utility rooms. To mount the receiver, do the following: 1. Remove the appropriate knockouts on the top of the control panel enclosure for the antenna shrouds. 2. Assemble the antenna shrouds and fit the black O-rings to the bottom of each shroud. 3. Insert the shrouds into the knockout holes (Figure 1). Figure 1. Installing the antenna shrouds 4. Use the mounting screw provided to loosely install the edge guide standoff in the lower mounting hole in the appropriate space to the left of the control panel (Figure 2). Do not tighten the mounting screw down at this time. Figure 2. Installing the edge guide standoff 5. Slide the printed circuit board into the antennae shroud slots, after inserting wires into antennae shrouds (Figure 3). Figure 3. Anntennae shrouds WWAARNING: To avoid possible equipment damage or personal injury, remove power from the control panel before making any wiring connections to the receiver.

Align the bottom of the circuit board in the edge guide standoff and twist the standoff into place (Figure 4). Tighten the mounting screw (Figure 2). Figure 4. Installing the circuit board Antenna shroud Enclosure Circuit board Edge guide standoff External mounting This installation uses enclosure model NX-569 (600-1029-03). The module comes as a kit that is assembled in the field. Use the following installation guidelines: • Allow at least 10 in. (25 cm) of clearance above the enclosure for the antennas. • Use the wire length guidelines in Table 1. Table 1. Wire lengths Wire gauge (shielded or unshielded) Maximum wire length between module and panel 22 AWG (0.65 mm) 250 feet (76 m) 18 AWG (1.02 mm) 500 feet (152 m) • Install the module in its own plastic enclosure. It should not be installed inside the panel’s enclosure. • Avoid mounting locations that expose the module to moisture. • Avoid areas with excessive metal or electrical wiring including furnace and utility rooms. If unavoidable, mount on or near metal with the antenna extending above the metallic surfaces as shown in Figure 5. Figure 5. Mounting on or near metal Metal Metal Tools and supplies needed To complete the installation, you will need the following tools and supplies: • Screwdrivers; • Drill with bits; • Mounting screws and anchors (included); and • 3-conductor, 22-gauge (0.65 mm) or larger, stranded wire. Mounting The module can be mounted on any interior wall (protected from the elements). To mount the module, do the following: 1. Remove the module back plate from the packaging. 2. Hold the base against the mounting surface and mark the two mounting holes and the wire access hole as shown in Figure 6. Remember to leave at least 10 in. (25 cm) above the back plate for the antennas. Note: The wire access hole is molded into the plastic so that you can access the wire, yet keep it hidden from the back plate. Figure 6. Back plate Antenna shroud locations Mounting hole Mounting hole Wire access 3. Drill holes and insert the appropriate anchors (included). 4. Run a 3-conductor, 22 or 18 gauge (0.65 or 1.02 mm) stranded wire cable from the module wire access hole location to the panel (Fig...
