AB708 1-Call Surface Remote Station

The AB708 remote station is similar in design to the AA702 Master Station, but without display and keypad. It is designed for indoor conditions and is suitable as a door station.

The station is equipped with a call button activating the door bell function to all stations programmed as receivers of this function. Stations receiving the distinctive door bell chime pattern can reply to the door call by dialling "5". A normal two way connection is then established.

Removing a jumper in the station allows dialling to subscriber no.13 only. The surface mounted station can easily be converted to a flush mounted model by using the clipon front plate BF636 and the BBF602 flush backbox.
