The BTR-240 system operates in the licence-free 2.4GHz frequency band and delivers full-duplex operation for up to 8 beltpacks with an almost unlimited number of half-duplex beltpacks. The system offers two separate audio channels allowing users to communicate on either or both channels. Talk and listen and listen-only modes are selectable on individual or both channels.
The BTR-240 wireless intercom system is suitable for stand-alone operation or can be directly interfaced to wired systems including RTS, Tecpro and Clearcom.
TR-240 beltpacks can be configured in one of three operating modes: wireless, wired or master wireless. In wireless (normal) mode, beltpacks communicate to each other using the base station as a relay. In wired mode, beltpacks turn off their wireless ability and communicate via an Ethernet cable or through a building's existing Ethernet infrastructure. In master wireless mode, a beltpack itself acts as a mobile access point to provide wireless coverage for other beltpacks to communicate without an actual BTR-240 base station.
Beltpacks incorporate removable, rechargeable Li-Ion batteries which offer up to 8 hours continuous use and can be re-charged within the beltpack or externally using the CHG-240 4-way battery charger.
