Restore proper control and status functions to a Detex EExER delayed-egress with electric latch-retraction system with the Detex 105083 Remote Interface Unit (RUI) Circuit Board Kit.

This genuine Detex replacement circuit board installs in the 103823-X Remote Interface Unit used with compatible Detex Series 800 EExER control systems. The board provides connections for the key-cylinder input, red and green status LEDs, horn, and system ground.

Ideal for repairing an existing remote interface without replacing the complete controller or remote-interface assembly.

Important Compatibility Note

Detex 105083 is not the standard replacement circuit board for the EAX-2500 exit alarm.

The Detex EAX-2500 uses a different circuit board assembly. Always verify the existing controller, remote-interface assembly, and part number before ordering.

This listing is for the 105083 circuit board kit only. Remote-interface enclosure, cover, cylinder, cam assembly, controller, cabling, and other components are not included unless specifically stated.
