Aiphone GT-RY External Signaling/Option Relay

Improve entryway response and system integration with the Aiphone GT-RY External Signaling/Option Relay. Designed for Aiphone GT stations, this external relay provides a normally open dry-contact closure on tenant call-in, enabling instant activation of external lights, alarms, door release mechanisms or other auxiliary devices. The GT-RY’s zinc die-cast housing and compact dimensions (2.2" W x 0.9" D x 1.4" H) make it a durable, space-efficient addition to intercom and access control installations.

For security integrators and facility managers, the GT-RY enhances surveillance and monitoring workflows by automating visual and audible signaling at the entrance—reducing response times and improving situational awareness. Its simple wiring and compatibility with the GT series minimize installation time and complexity, while NDAA compliance supports government and enterprise procurement.

Add the Aiphone GT-RY relay to your intercom or access control system to extend functionality—whether triggering entrance lighting, integrating with alarm systems, or coordinating with monitoring stations. Order the GT-RY to strengthen your site’s security and streamline entry management.
