Detex 104395-2L Transformer Board

S&R Power Supply PWA | Replacement Board for 84-800 & 85-800 Controllers

Restore the power-supply section of a compatible Detex Series 800 controller with the Detex 104395-2L S&R Power Supply PWA.

Designed for use in the Detex 84-800 and 85-800 Logic / Power Supply Controllers, this factory replacement board is part of the system that provides regulated 24VDC power for compatible delayed-egress and electric latch-retraction exit hardware.

Detex factory wiring diagrams identify part 104395-2L specifically as the S&R Power Supply PWA.

Key Features

• Genuine Detex replacement component

• Part Number: 104395-2L

• Factory designation: S&R Power Supply PWA

• Used in the Detex 84-800

• Used in the Detex 85-800

• Part of the regulated 24VDC power-supply system

• Designed for Series 800 controller repair

• Supports compatible electrified exit-device systems

• Ideal for replacing a failed or damaged original board

• Professional service component for commercial door systems

84-800 Compatibility

The Detex 84-800 is a single-door controller and power supply designed for integrated delayed egress with electric latch retraction (EExER) applications.

Detex identifies the 104395-2L S&R Power Supply PWA directly in the 84-800 factory wiring diagram.

The 84-800 provides:

• Single-door operation

• Regulated and filtered 24VDC power

• Delayed-egress interface

• Electric latch-retraction control

• Fire-alarm input

• Automatic-door operator signaling capability

85-800 Compatibility

The 85-800 is designed for two-door delayed-egress and latch-retraction applications.

Its factory power section uses both:

• 104395-2L

• 104395-2R

The 104395-2L is therefore one of the power-supply boards used inside the 85-800 enclosure.

Series 800 Application

Detex designed the 84-800 and 85-800 systems specifically for integrated EExER delayed-egress with latch-retraction exit-device applications.

The controllers convert incoming 120VAC power into regulated and filtered 24VDC for compatible Detex electrified hardware.

Common Applications

• Detex 84-800 Controllers

• Detex 85-800 Controllers

• Advantex Electrified Exit Devices

• Delayed Egress Systems

• Electric Latch Retraction

• EExER Exit Devices

• Automatic Door Integration

• Commercial Exit Hardware

• Access-Controlled Egress Doors

• Series 800 Controller Repair

Important

The 104395-2L is an internal electrical service component, and Detex specifies that connections and adjustments to the 84-800 and 85-800 must be performed with the power supply de-energized and the main power switch turned off.

Before ordering, verify:

• Existing controller model

• Existing board part number

• 84-800 versus 85-800 configuration

• Location of the failed board

• Wiring and harness connections

• Condition of the remaining controller components

For an 85-800, do not substitute the 104395-2L for the corresponding 104395-2R board without confirming the required position and Detex wiring configuration.
