Restore a compatible Detex V40 Value Series weatherized rim exit device with a matching factory 104287 EX-W request-to-exit fillerplate subassembly. The 104287-2 fits the specified 36-inch configuration, while 104287-4 fits the specified 48-inch configuration. Both are designed for EX-W weatherized pushpad request-to-exit monitoring with LD less dogging, as documented in the original product descriptions.
Order by installed factory device length and function. The 36-inch and 48-inch replacement fillerplates differ physically and are not complete exit devices. Confirm compatible V40 weatherized hardware, correct switch and wiring connection, mounting points and seals before substituting either model.
Factory Variants

Ordering and Installation Notes
- Read the full V40 exit-device SKU and compare the old fillerplate part number and mounted pushpad length.
- Confirm the EX-W switch, LD less-dogging preparation, electrical connections, appropriate cable path and weather seals.
- Follow manufacturer replacement instructions and protect the egress device and any connected alarm/access-control components during service.
- Test positive latching, free emergency exit, monitored EX-W signal and water-resistant assembly features where applicable.
Factory Package and Accessories
One selected Detex factory assembly identified by its complete SKU. Exact hardware, locking cylinders/keys, wiring, power accessories and installation materials vary by configuration; match current Detex package details rather than assuming every option is included. The following original detailed descriptions are preserved for each source model.

Additional Product Specifications and Ordering Guidance
Service-Part Compatibility and Replacement Steps
Detex service parts fit specific Value Series or Advantex subassemblies. A narrow-stile center case, electrical fillerplate or weatherized replacement differs from a complete exit device and may not fit another device merely because it has the same nominal length.
Factory item on this listing: DTX104287-2.
Product Selection and Installation Checklist
- Read the complete host device and original service-part number, including suffix and hardware series.
- Check factory length, pushpad and fillerplate mounting, dogging mechanism, alarm/EX switch and weatherized seals.
- Compare the manufacturer parts-breakdown drawing and any revision-specific connectors, springs and retaining screws before service.
- Determine what subcomponents, trim or wiring are sold separately to complete the repair.
Acceptance and Service Verification
After installation test latch/strike alignment, pushpad travel, correct sensing/dogging operation and unrestricted manual egress.
Factory Package and Related Components
One specific Detex replacement component or kit, not the full exit device or a complete electrical controller. Consult the original model specifications below when matching the factory SKU to an existing opening.
For facility managers, building engineers, and maintenance technicians, identifying the correct subassembly helps simplify purchasing and repair planning. Keep this part on hand for compatible devices across your facility.
- Targeted repairs: Replace the required fillerplate subassembly while retaining serviceable surrounding hardware.
- 36-inch door application: Select the assembly specified for your existing device’s nominal door width.
- Configuration-specific replacement: Designed for the EXxW, less-dogging setup.
- Clear inventory identification: Part number 104287-2 helps maintenance teams organize spares and work orders.

Additional Product Specifications and Ordering Guidance
Replacement-Part Identification and Mechanical Fit
Detex replacement covers, fillerplates, center-case assemblies and related service components often share an outward appearance while differing in device series, length, strike preparation, weatherization and alarm/dogging functions. Use the factory parts breakdown to match the existing installation.
Product SKU: DTX104287-4.
Hardware Schedule and Ordering Checklist
- Read the part number on the installed assembly and determine the exact Detex Value Series or Advantex host device.
- Confirm the specified 36/48-inch factory length, wide/narrow stile, component mounting and required end-cap or center-case design.
- Where an alarm or EX/EE function is present, compare switches, circuit connections and weatherized seals; a plain mechanical filler may be incompatible.
- Check whether the replacement includes retaining screws, spring parts, keys, a cylinder or other subcomponents; order missing accessories separately.
- Weatherized factory hardware needs the manufacturer-approved seals, protected cable path and correctly rated remote electronics. Standard accessories may not share the weather rating.
Installation and Acceptance Checks
Test mechanical pushpad travel, correct latch/strike engagement, required dogging and alarm/monitoring functions, and unobstructed emergency egress after service.
Factory Package Scope
One replacement component or factory subassembly as identified by the exact SKU, rather than the complete exit device or its outside trim. Preserve and review the original detailed specifications below for the particular Detex model.
When the pushpad is depressed, the EX-W switch changes contact state, allowing the device to signal a compatible access-control panel, alarm, remote strobe, monitoring system, or separate delayed-egress controller.
The 104287-4 is specifically the 4-foot / 48" Less Dogging (LD) configuration.

EX-W Weatherized Request-to-Exit
The EX-W option provides a weatherized switch that electronically monitors the exit-device pushpad.
When the pushpad is operated, the switch can provide a signal to compatible equipment such as:
-
Access-control panels
-
Security systems
-
Alarm systems
-
Remote horns
-
Remote strobe lights
-
Monitoring stations
-
Separate delayed-egress controllers
The weatherized construction makes EX-W particularly useful on exterior gates and doors exposed to moisture.
SPDT / Form C Switch
The EX-W switch provides SPDT / Form C contacts:
Yellow: Normally Open
Brown: Common
Green: Normally Closed
This allows the installer to configure either a Normally Open or Normally Closed signaling circuit depending on the connected control system.
Important EX-W vs. EXV-W Distinction
The EX-W is designed primarily as a low-current signaling / Request-to-Exit switch.
If the application requires the exit device switch to directly shunt power to an electromagnetic lock, Detex specifies the separate EXV-W high-current weatherized switch.
48" / 4' Configuration
Detex identifies:
104287-2 – EX-W fillerplate, 3' / 36", LD
104287-4 – EX-W fillerplate, 4' / 48", LD
This listing is specifically for the 104287-4 48" version.
Less Dogging – LD
The 104287-4 is an LD / Less Dogging configuration.
It does not include a standard mechanical hex- or cylinder-dogging function.
Verify the existing exit device configuration before replacing the fillerplate.
Weatherized Applications
Ideal for compatible Detex hardware installed on:
-
Exterior commercial doors
-
Security gates
-
Garden-center exits
-
Warehouse exterior doors
-
Loading areas
-
Industrial facilities
-
Outdoor secured openings
-
Perimeter gates
-
Other wet or weather-exposed applications
