3.2 Installing External Cell Modem Antenna
A small panel mount antenna (provided with the Controller) is to be installed on top of
the unit Enclosure. Run the antenna cable thru the mounting hole on top of the
enclosure. Connect the antenna cable onto the SMA Male connector behind the touch
screen display. Secure the antenna on the enclosure. See the drawing below for
mounting. Also Refer Figure 2 to connect the SMA connector of the Antenna cable to
the back of the PLC Control Display.
3.3 Installing Antenna for Wireless Communication
An Omni Directional antenna must be used for PT2000H Series controller to
communicate with the remote wireless detectors. Antenna should be installed at an
elevated height for better line of sight. It is essential that proper coax cable must be
used to connect the Antenna to the controller. The antenna and coax cable are
typically supplied as a set to match the dBi gain of the antenna with the signal loss in
the cable. A surge suppressor is installed inside the controller. All the field ground
wires must be grounded properly to ground all the surges and avoid damage to the
Wireless RF Module.
Refer to Figure 2 for connection details.
