Automatic Fire Alarm Warden Station (AFAWS-Series) telephones are
compatible with the FFT-7 and FFT-7S master telephone stations. The
series has a handset with a push-to-talk switch, a hearing aid-compatible

connected to the master telephone station. Up to seven handsets
(including the master handset) may be operated simultaneously. AFAWS
