OR541U Aluminum Remote Station with In-Use Privacy L.E.D.
The OR541U Aluminum Remote Station provides for "CALL" capability and two-way, hands free communication to inside master stations. The OR541U features a built-in L.E.D. (located in the call button) to signal the remote that the master has established voice communication.

Designed for flush or surface mount applications, the unit provides natural, clear voice communication, simple push button operation, and hands free reply. The station is ideal for outdoor use, in home, office, plant, warehouse, retail applications. It is also a popular choice for emergency elevator cab intercom locations.

The operation of the station is simple and efficient. The caller, by pressing the "CALL" button, causes an audible/visual signal at the inside master station location(s). The identity of the calling station is shown on the master by an indicator light.

The OR541U Aluminum Remote Station is used with the SM400 Series intercom system, to provide a complete system with twoway communication and eavesdrop privacy
