Detex Logic Controller – 102879-3

Door Controller PWA | EE/ER Control Board | OEM Replacement Component

Restore the control functions of compatible Detex electrified door equipment with the Detex 102879-3 Logic Controller / Door Controller PWA.

Detex identifies the 102879-3 as the internal Door Controller PWA used within compatible Series 800 control equipment, including the Detex 84-800 EExER controller/power supply.

This replacement circuit board manages door-control functions within the system and is intended for professional repair of an existing compatible Detex controller rather than use as a complete standalone power supply.

• Factory designation: Door Controller PWA

• Also cataloged as an EE/ER Controller PWA

• Used in compatible Detex Series 800 control systems

• Factory-documented in the Detex 84-800

• Internal logic/control replacement board

• Designed for electrified commercial door systems

• Ideal for controller repair and service

84-800 Compatibility

Detex's factory 84-800 wiring diagram specifically identifies:

Door Controller PWA – P/N 102879-3

The 84-800 is designed for a single-door EExER application combining:

• Delayed Egress

• Electric Latch Retraction

• Automatic Door Operator Interface

• Fire Alarm Integration

• Electrified Exit Device Control

Within that system, the 102879-3 serves as one of the internal control boards.

EE / ER Control Application

The 102879-3 is also commercially identified as:

PWA EE/ER Controller

This reflects its use in Detex electrified systems involving functions such as delayed egress and electric latch retraction.

Not a Complete Controller

The 102879-3 is an internal circuit board only.

It does not include:

• Series 800 enclosure

• Transformer

• Power supply board

• Delayed-egress board

• Remote Indicating Unit

• Terminal strips

• Wiring harnesses

• Battery backup

• Complete 84-800 controller assembly

If a complete control system is required, select the appropriate Detex controller/power supply for the application.

Common Applications

• Detex 84-800 Controller Repair

• EExER Systems

• Delayed Egress

• Electric Latch Retraction

• Automatic Door Integration

• Electrified Exit Devices

Important

Before ordering, verify the part number printed on the existing circuit board and the model of the Detex controller being serviced.

The closely related 85-800 uses a different Door Controller PWA, part 102879-4, so the 102879-3 should not automatically be substituted into an 85-800 system.

Electrical service should be performed with the controller properly de-energized and by qualified personnel familiar with Detex electrified exit hardware.
