RY402 3-Remote In-Use Adapter (SM400 Series)
The RY402 is an adapter used to provide monitoring (listening) in-use L.E.D. capabilities on up to three (3) remotes in an SM40X intercom system. These monitoring L.E.D.'s are required to comply with Federal and Local 'privacy' laws, by letting people know when they are being 'monitored' or 'listened to', with a remote L.E.D. It is also used in elevator emergency intercom, and other A.D.A. applications, to let a call know their call for help has been acknowledged, even if they are hearing-impaired.

The RY402 is typically used with our model IR141PIR143P, OR54SS and OR541U remote stations, with built-in privacy L.E.D, on the SM40X series intercom system. One (1) RY402 is required for each three (3) or less of these 'privacy' L.E.D. remotes.

Connections to the unit are made via a pigtail wiring harness connector, which is supplied. The connector is color-coded, with wiring designations on the unit's case.
