IR140 Series Indoor Remote Stations
The IR140 Series Indoor Remote Stations combine modern styling with ease of operation to provide natural, clear voice communication. Advanced circuitry allows for simple push button operation and hands-free reply. The stations are ideal for use in office, home, plant, warehouse, retail business, and similar applications.

The operation of the stations is simple and efficient. The caller, by pressing a 'Call' button, causes an audible and visual signal at the master location. The identity of the calling station is shown on the master by an L.E.D. indicator light.

The IR140 Series Indoor Remote Stations may be used with the SM400 Series master stations to provide a complete system with two-way communication, select-able privacy and paging, as well as background music.
