AA705 Heavy Industrial Master Station

The AA705 Heavy Industrial Master Station is a surface mount, splash-proof model, designed for humid, dirty and outdoor conditions and areas where extreme noise occurs. The station is equipped with noise cancelling microphone. The AA705 consists of an Orange Makrolon plastic (surface) housing and a membrane film keyboard.

The station has an internal 3 Watt amplifier and the speaker volume is adjustable with switches located inside the station, for four (4) levels. The unit requires connection of an external loudspeaker (model 306-45, model 1845 or equivalent), and is prepared for connection of an external speaker. As an optional feature, a 10 Watt power amplifier FC740 may be used with this station. The FC740 also allows you to use the loudspeaker both as loudspeaker and microphone if required, (talk-back). An optional model no. GD571 add-on handset is also available.

The AA705 offers a remote control output which can be used to drive external call indicators (lamp/buzzer) or for general remote control facility activated by the calling subscriber.
