RY014B Specialty Relay

The Alpha Communications® RY014B specialty relays are used to provide a 'Form C' relay contact, from the tone signal generated by the IA543 or PK543A amplifier (or equivalent). The RY014B can be connected to a standard IR204E (or equivalent) apartment intercom station, and when the station is called from the lobby the RY014B provides a 'Form C' contact. This enables the user to connect an auxiliary signaling device, such as a strobe, loud bell, etc., off of the apartment station, when the lobby or entrance places a call.

As long as a the tone signal source is present, the RY014B will engage, providing a normally-open and a normally-closed set of contacts, with a shared 'common' screw terminal. The circuitry on the RY014B is designed to detect even the tiny current created by the IA543 or PK543A tone oscillator.

The RY014B relays are very compact, and are designed to easily mount right behind and inside the apartment station(s).

Wiring connections are positive screw terminal type.
