System Overview
Model PT750 Series Wireless Annunciator is designed to communicate with the Fixed Gas
Control panel on the main Rig and the Wireless Control Panel on the Rig Camp. The line of
sight distance is 2 Km using dipole antenna.
The color touch screen display provides continuous gas readings for all the detectors
connected to the (fixed) main control panel and the wireless controller. Up to 16 detectors
can be displayed on a standard unit with 4.5” display screen. A larger screen display is used
for more than 16 channels.
PT750 requires RS-485 data transmitters to be installed on both Fixed and Wireless control
panel. No hardware configuration is required. Once RS485 data transmitters are installed on
the gas control panels, simply connect the AC power to the unit, follow a simple configuration
of the channels as outlined in the next section and the unit should be fully operational.
Installation
PT750 Annunciator is a wall-mount fiberglass unit. Annunciator must be installed indoor.
Simply mount the unit to the wall. If the line of sight is not clear to the RS-485 transmitter on
the fixed control panel or the wireless controller then external antenna at an appropriate
height must be installed. Connect the external antenna and the annunciator using a low loss
coax cable.
