Installation
1. Determine the optimal location of the FPX and
antenna for RF communications.
2. Mount the FPX using the provided screws.
You can also use double-sided tape or VELCRO
fasteners.
3. Set the Channel and Network ID switches to
their appropriate settings.
4. Connect the communication port of the field panel
to the FPX (cable length limit is 4000 ft.).
5. Connect 24 Vac power.
6. Connect the antenna. Be sure the antenna is
securely connected to the FPX.
For a remote mount antenna, do the following:
a. Locate the liquid tight fitting so that the
antenna extension cable does not incur
excessive pull force. At the desired enclosure
location, punch a 1/2" knockout and use the
locknut to secure the body of the liquid tight
fitting into the knockout.
b. Route the antenna through the body of the
liquid tight fitting (Figure 4). Hand-tighten the
liquid tight fitting nut to secure the antenna in
place.
Make certain the liquid tight fitting nut
tightens on the antenna base, not the
antenna itself, so the antenna can be
articulated.
c. Connect the antenna wire securely to the FPX.
7. Position the antenna in a vertical orientation (up
or down).
The installation is complete.
