AA703 Industrial Master Station

The AA703 is a surface mounted splash-proof master station designed for humid, dirty and outdoor conditions. It has a flame and chip-resistant casing of durable Bayblend plastic. The front can be removed to allow easy access during installation and service.

The station has an internal 3 Watt amplifier and the speaker volume is adjustable with switches located inside the station, for four levels of volume. In addition to the built-in loudspeaker, the unit is prepared for connection of an external speaker. As an optional feature, a 10 Watt power amplifier (model 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), for higher-power applications.

The AA703 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. The AA703 meets stringent Ingress Protection Standard number IP64. An optional model no. GD571 add-on handset is also available.
