The Z-704 4-zone indicator lamp provides light annunciation at the junction of hallways or corridors, indicating the area in which there is an unanswered call. Up to four zone lights can be included in a system. The zone indicator lamp displays up to four white lamps when any call in a zone has been placed, allowing the staff to quickly assess where their attention is needed. The lamp will go off when there are no more unanswered calls in the associated area. The zone indicator lamp can be mounted onto a standard 5-gang box on a wall, or directly onto a ceiling, whichever is most visible. The unit comes with label numbers 1 to 4 for easy zone identification. Wiring to the zone indicator lamp is 5 conductors from the central control unit.
