APPLICATIONS
The CX-12 PLUS Interface Relay is ideal for control and integration of automatic doors utilizing electro-mechanical
locks (including electric strikes and magnetic locks) in any commercial, institutional and multi-unit residential
application. Operating modes support bi-directional sequencing of two vestibule doors, basic restroom control, both
secured and unsecured, a maintained output for fire alarm integration, and a telephone entry panel input that
simplifies wiring, and eliminates the need for an isolating relay.
