Tecpro beltpacks are tough, lightweight, remote intercom stations which are typically hung from the belt but can be used freestanding or mounted on a suitable surface. They offer full-duplex operation and have been designed for portable use where care may not always taken by the user. Series 2 beltpacks retain the robustness and simplicity of previous Tecpro designs while extending their performance to meet current operational requirements. They are compatible with earlier designs of Tecpro equipment. Six versions are available, for communication on either single or dual circuits.
