Product summary
The NX-148E-RF Touchpad with Receiver combines touchpad
and receiver capabilities into a single device for use with all
NetworX control panels except CF (commercial fire) panels.
Note: When using this touchpad with an NX-8E, NX-8V2, NX-6V2,
or NX-4V2 and downloading via modem, make sure the
control panel version is equal to or greater than the
following versions:
• NX-8E 17.00

Installation guidelines
Use the following installation guidelines:
• Mount transmitters as close as possible to the touchpad. For
best results, we recommend the distance between the trans-
mitter and the touchpad be less than 100 ft. (30.5 m).
• Mount the touchpads in an environmentally controlled area
with a temperature range from 32 to 120°F (0° to 49°C).
• When mounting the touchpad, allow at least 3 in. (7.6 cm)
below the touchpad for the swing-down door (Figure 1).
