Fire Fighter's Telephones (FFT-7/FFT-7S)
Overview A Fire Fighter's Telephone provides the Voice Alarm System with fire-fighter control of
paging, and two-way communications in an emergency situation. Connect the FFT-7 to
an Audio Message Generator (AMG-1) or Audio Tone Generator (ATG-2). Up to seven
telephones can converse at the same time. Fire Fighter's Telephones come in two
models:
FFT-7 – provides full capability including paging.
FFT-7S – provides same features as the FFT-7, without paging capabilities.
