The JOW-2D is an adaptor for the JO Series video intercom system that will allow two video door stations to be on the system. The adaptor has inputs for two JO video door stations and outputs to control door release for each of those door stations. When either door station calls in, that image will be displayed on the inside station(s). The person inside answers the call, and when pushing the door release button, only the associated door release mechanism will trigger. If one door station is in use, the call button on the other door station will not activate a call-in.
