4-Wire Surface Mount Apartment Intercom Station

IR-204E is a popular 4–wire version of the IR-203E. IR-204E can be mounted to a single gang ‘gem’ box, or surface mounted directly to the finished wall using wall plugs. Additional functions include multi-entrance operation with the PK502B, AC or DC door operation selectable by terminal connection with selectable delayed action door release set at the dip switch, post office door lock release and a tone signal to call remote stations. A steady or warble tone can be used to identify calling from the main entrance panel and a call button located at the suite entrance. Braille legends, in addition to English language and icon symbols make this station easy to operate by all.

System Operation: The visitor, by pressing the appropriate button on the entrance panel, causes an electronic tone signal to be heard at the ‘IR’ (Inside Remote) station. The resident responds by pushing the TALK button while speaking to the caller, the LISTEN button while waiting for a reply, and the DOOR button to allow entry to the building.
