Aiphone RY-AC/A External Signaling Relay, LEF

Ensure every visitor call is noticed with the Aiphone RY-AC/A external signaling relay. Designed for intercom and entry systems, this relay activates an external doorbell, buzzer or visual indicator the moment a door station call is received, improving response times for reception, security, and facilities teams. The RY-AC/A provides momentary activation that mirrors the door station call button, delivering consistent, predictable signaling for monitoring and visitor management. Built for easy wired integration, it is compatible with LEF, TD-H and IE-8MD intercom systems and comes in a compact ABS housing suited to commercial deployments. TAA and NDAA compliance make it a solid choice for government and enterprise security programs. Because the relay accepts externally supplied power and signaling devices, you can tailor installations to existing infrastructure and surveillance strategies. Add the Aiphone RY-AC/A to your access control or security monitoring setup to extend audible and visual alerts across facilities—order today to improve situational awareness and streamline visitor handling.
