The HCU-317 RTS Intrinsically Safe Beltpack from Telex is a part of a security intercom system. The HCU-317 and its additional required system components (sold separately) can be connected to all RTS party-line stations which have been the industry standard of advanced professional party-line communication systems. The HCU-317 beltpack is designed to be intrinsically safe, which means that the beltpack can be used for communicating in areas that are at high risk for explosion such as aviation fuel tank cleaning areas, oil platforms, industrial, or chemical areas. The HCU-317 beltpack offers full duplex operation mode for communication.
The HCU-317 beltpack has to be connected to a WB-5 wall box via a CA-NG50 cable, and requires the PH-200-HCU headset which is equipped with a special intrinsically safe connector (WB-5, CA-NG50 and PH-200-HCU all sold separately).
