JOW2D Dual Door Adaptor for JO Series - AIPHONE

The Aiphone JOW2D is an adaptor for the JO Series video intercom system that allows two video door stations to be used, with or without door release function (without this unit the JO1MD/W only accommodates a single door station). The adaptor has inputs for two JO Series video door stations and separate contact outputs for door release for each of those door stations. When a door call is answered on an inside station, the person at the JO-1MDW, JO-1MD, or JO-1FD, can push the door release button to only activate the electric lock at the door the call was placed from. (Note: If one door station is in use, the call button on the other door station will not activate a call.)
JOW2D can be added to existing systems with only a single door station to expand to a second external door station.
