surface to discharge static electricity.

2. At the mounting location, use the mounting plate to mark

the location for the antenna and mounting holes (Figure

2).

3. Drill 15/64 in. holes at the marked antenna hole locations.

WARNING: Make sure the mounting location is free of

electrical wires. Contact with electrical wires while drilling the

antenna openings could result in serious injury or death.

4. Mount the mounting plate to the wall with the screws

provided. Use wall anchors if needed.

5. Remove power (if applied) from the control panel.

WARNING: To avoid possible equipment damage or personal

injury, remove power from the control panel before making any

wiring connections to the module.

6. Use 22-gauge or larger wire to connect the data, common,

and positive terminals on the touchpad (Figure 3) to the

data, common, and power terminals on the control panel.

See Table 1 for wiring guidelines.

Transmitter programming

This section describes how to program the wireless

transmitters used with the touchpad.

Programming guidelines

Use the following programming guidelines:

• NX-4 and NX-6 control panels can have receivers added

with zones that overlap those contained in the control

panel. No hardwire expanders can be used.

• NX-8 control panels can have expansion zones (hardwire

or wireless) set the same as those contained in the control

panel. To do this, you must disable the onboard control

panel zones in panel location 37, segment 5, option 3. All

zone expansion modules must not overlap any blocks of 8

zones.

• All other control panels can have wireless zones added to

any zone. If a hardwire input (on either the control panel or

hardwire expander) is also present on the same zone as

an enabled wireless zone, the wireless transmitter takes

priority.

Program settings

When programming wireless transmitters into the touchpad,

there are various options and partitions you can set for each

transmitter. These settings appear in segments of each

programming location.

Use Table 11 to record zone assignments and settings. Be

sure to circle the module type in the location column to help

identify where each zone resides.
