*SpOrd* Aiphone RY External Signal Relay

The AI-RY-ES is a relay used to activate an external signaling device when the door station calls in. It can be used for call extension on the JP, JO, JK, JF, KB, AX, NIM, DB, and IE systems (excluding IE-8MD). The relay connects to the chime output of the master station in place of the AI-IER-2. The AI-RY-ES relay will share power with the master station.
