Project List Available
The BTR-800 wireless intercom system is the ultimate in full duplex, high fidelity communications.The BTR-800 system consists of the base station, and up to 4 beltpacks, all operating in full duplex mode. The BTR-800 system includes the base station and up to four beltpacks, all operating in full duplex mode. The BTR-800 can generate two channels of audio, giving operators the option of two channels of audio communication with the base station managing the beltpacks. The BTR-800 is designed to operate both alone and in conjunction with intercom systems such as those developed by RTS TW (2-wire), AudioCom, ClearCom, RTS matrixes or other 4-wire intercom equipment.
