RUI Remote Interface Board | EExER Delayed Egress Systems | Key Cylinder Input | LED & Horn Control | 84-800 / 85-800

The Detex 105083 EExER Remote Interface Circuit Board Kit is a genuine replacement RUI circuit board designed for compatible Detex delayed-egress and electric latch-retraction systems.

Installed inside the Detex Remote Interface Unit, the 105083 provides the electrical interface for the keyswitch, status LEDs, horn, and controller connection used with compatible EExER systems.

This replacement board is commonly used with Detex 84-800 and 85-800 Series controller installations and is ideal for repairing a damaged or malfunctioning remote keyswitch/interface assembly without replacing the complete control station.

Remote Interface Functions

The Detex 105083 provides connections for several functions within the Remote Interface Unit.

Supported Connections

• Green LED Control

• Red LED Control

• Key Cylinder Input

• Horn Negative

• Horn Positive

• Ground

These connections allow the remote interface to provide visual and audible system status while giving authorized personnel keyswitch control of the delayed-egress system.

Key Cylinder / Dummy Cylinder Selection

The 105083 board includes an S2 selector / shunt setting that allows the Remote Interface Unit to be configured according to the installation.

Key Cylinder Application

Set S2 to ON when the remote interface uses a functioning key cylinder.

Dummy Cylinder Application

Set S2 to OFF when a dummy cylinder is used and keyswitch operation is not required.

Always verify the existing installation before changing the board configuration.

EExER System Application

The Detex EExER system combines:

• Delayed egress

• Electric latch retraction

• Remote system control

• Audible alarm functions

• Status indication

• Fire-alarm integration through the associated controller

The 105083 Remote Interface Board serves as the interface between the remote control station and the associated Detex controller/power supply.

Compatible Applications

Designed for compatible Detex systems including:

• 84-800 Single-Door EExER Systems

• 85-800 Two-Door / Pair EExER Systems

• Detex Remote Interface Units

• Key-operated delayed-egress control stations

Always verify the existing board part number and system configuration before ordering.

Replacement Applications

The Detex 105083 is ideal when servicing a remote interface experiencing issues such as:

• Keyswitch not controlling the system

• Status LEDs not operating correctly

• Remote horn not functioning

• Damaged circuit board

• Corroded or damaged terminals

• Intermittent remote-interface operation

• Failed EExER remote control station

Proper troubleshooting should be performed before replacing the circuit board.

Important EAX-2500 Note

The 105083 is an EExER Remote Interface circuit board, not the standard replacement alarm board used inside a standalone EAX-2500 exit alarm.

The EExER remote interface uses a keyswitch-style control assembly with several components also associated with Detex remote alarm/control hardware, which can lead to it being described as an EAX-2500-style keyswitch interface.

Verify part number 105083 on the existing board before ordering.

Installation Note

The Detex Remote Interface enclosure must be properly grounded according to the installation instructions.

Installation and service should be performed by qualified personnel familiar with:

• Delayed-egress hardware

• Electrified exit devices

• Access-control wiring

• Commercial life-safety systems

Power should be disconnected before servicing the Remote Interface Unit or associated controller.
