AB731 and AB731-F Tamper-Resistant Remote Stations
Model AB731-F Shown

These PRO700 remote stations are compact, dust resistant, and feature robust construction. The stations are made in stainless steel with a 2.0 mm thick front-plate. The construction insures optimal protection of the push-button, microphone and loudspeaker. The stations are ideally suited for applications in correctional institutions, prisons, police stations, parking garages, subway stations, and other hi-abuse locations.

The AB731-F is for flush mounting and comes with a light duty backbox for EMC protection. When an optional backbox is needed for concrete mounting, the model BBF731 must be ordered.

The station has an internal loudspeaker with a 3 Watt amplifier. An optional external speaker can easily be connected. The stations are equipped with a call button for establishing connection with extension number 13. The same call button may optionally be used for door bell function.
