4 Station Door Entry Kit - Surface
Alpha Audio Door Entry
The Alpha range is our standard but extremely successful range of audio door entry systems that has now been extended to provide equipment in kit form for up to 32 flats, with surface or flush door panels, with or without a tradesmans facility. All Alpha range systems can be run either AC or DC and are therefore ideal for battery back up, interfacing with other equipment or extending with additional telephone handsets, extension sounders, flashing strobe lights, multi-entrance switching units, Alpha-LS apartment stations etc.
The standard Alpha audio door entry system (common speech) operates on 4 common wires plus one individual ringing wire per flat with Alpha-PS audio door entry systems (private speech), needed 6 common wires and one individual ringing wire per flat.
