3.0 Setting Up PT2000 Controller
3.1Installing SIM Card for GPRS Cell Phone Module
The unit is shipped from the factory without any SIM card. User must install a valid SIM
card acquired from the local cell phone provider. This procedure is performed only
once upon receiving the brand new unit from the Pem-Tech. SIM Card does not need
to be removed from the controller when the system is not in use for extended period
of time.
Before installing the SIM card be sure that the power is completely removed. Also
extra care need to be taken when opening the back cover of the screen display. Avoid
opening the unit in dusty environment and avoid any static damage to the unit.
Following is the step by step procedure to install the SIM Card.
Remove Power from the unit if currently ON
Disconnect the power, USB Extension
Cable and RJ45 cable from the bottom of
the PLC Display screen. Remove the
screws (5 each) in order to remove the
back cover.
Lift to cover gently to avoid any damage
to the flex cables inside the unit.
Unplug power and Data Cables
Remove Screws to loosen the cover

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.
