The Command Access Technologies Request-to-Exit (REX) Switch Retrofit Kit provides a dedicated field-installable monitoring accessory for compatible Precision 2000 Series commercial exit devices. When the exit-device pushpad is operated, the switch sends a dry-contact signal to a compatible access-control or security panel, helping the system recognize an authorized exit event. Designed for existing mechanical and select solenoid-equipped Precision 2000 devices, the PREREXKIT-ED allows an appropriately specified opening to gain monitored exit functionality without replacing the entire panic device.

Monitoring Function and Retrofit Verification

The PREREXKIT-ED provides a discrete REX status signal for the compatible Precision 2000 Series exit-device mechanisms named in the manufacturer instructions. It does not motorize the exit bar or replace required mechanical panic or fire-exit functionality.

• Device survey: Verify the exact Precision 2000 model, mechanical versus electrically operated configuration, pushpad travel and compatibility notes.
• Controller planning: Use the manufacturer’s electrical contact rating and terminal diagram to connect REX monitoring; REX signaling is not the same as a latchbolt monitor or door-position switch.
• Commissioning: Confirm correct contact transition, reset and controller event interpretation throughout normal inside-exit operation.

Features and Benefits

• Precision 2000 compatibility: Manufacturer's REX retrofit kit specifically for the Precision 2000 Series exit-device platform. Confirm the exact installed model, device function and hardware revision before purchasing.
• Mechanical and solenoid device support: The Command Access compatibility chart identifies PREREXKIT-ED for supported mechanical and solenoid exit devices, not for motorized exit-device conversions. Do not substitute it for an unrelated MLRK motorized REX configuration.
• Pushpad-based request-to-exit: Detects mechanical panic-bar movement from the egress side and supplies an electrical contact transition that a connected controller can use for exit-event recognition.
• SPDT monitoring contact: A single-pole, double-throw (SPDT) switch offers a common terminal and normally-open/normally-closed contact paths for the required monitoring circuit.
• Low-voltage dry-contact interface: The manufacturer switch-kit family is published with a 0.5 A at 24V AC/DC contact rating and 22-gauge wire leads. Check current factory instructions and the supplied switch label before connecting.
• Field-installable design: Enables qualified technicians to add monitoring to an existing compatible exit device using manufacturer-specified internal mounting points and wire routing.
• Access-control integration: Useful for triggering an exit-request input, logging egress activity or coordinating a properly designed door alarm function without changing the physical means of egress.
• Maintains mechanical free egress: Proper installation leaves the normal pushpad and latch operation intact; the switch is a monitoring accessory and does not power the latch or control the door lock.
• Commercial facility application: Designed for appropriately specified schools, offices, government facilities, institutional buildings, healthcare administrative areas and commercial buildings equipped with Precision exit hardware.
• Three-year manufacturer warranty: The published Command Access exit-device switch kit family includes a three-year limited warranty; current terms and approved installation requirements apply.

Technical Specifications

What Does the REX Kit Do?

In a properly configured access-control opening, a request-to-exit switch informs the access controller that a person has pressed the exit-device pushpad to leave the secured area. The panel may use that input to recognize or log an exit event and to apply its programmed door-alarm behavior. The switch does not release an electric lock, retract the latch, energize a solenoid or replace the controller. Its only role is to provide the appropriate switch signal from a compatible Precision device.

Precision 2000 Compatibility Notes

PREREXKIT-ED is the manufacturer-designated field-installable REX switch for the Precision 2000 Series. It is shown as compatible with mechanical and solenoid-operated configurations in Command Access documentation, while motorized applications are excluded from this switch-kit entry. Verify the actual Precision model and the available switch mounting and internal space before ordering. This Precision kit is distinct from the Adams Rite ARREXKIT-ED, Von Duprin VDREXKIT-ED and other hardware-specific REX kits.

Installation Guidelines

1. Verify device identification: Confirm an approved Precision 2000 Series mechanical or solenoid-equipped exit device and check that the selected kit matches the manufacturer's latest compatibility matrix.
2. Review the factory instructions: Locate the specified switch installation position, pushpad contact point, mounting hardware and wire routing for this Precision model. Do not use a different manufacturer's drilling template.
3. Preserve normal exit function: Install the switch without restricting pushpad travel, latch engagement, trim operation, dogging or emergency egress.
4. Connect the monitoring conductors: Terminate common, normally-open or normally-closed contacts as required by the security system. Confirm conductor colors using the specific PREREXKIT-ED kit instructions, not an unrelated REX kit.
5. Check contact ratings: Do not route lock power or an unsuitable load through the REX switch. Match the panel input and low-voltage wiring to the manufacturer's electrical limitations.
6. Test all operating modes: Verify that the switch changes state when the pushpad is pressed, the controller detects the intended exit signal, the door relatches normally and emergency egress remains available.
7. Confirm compliance: Check applicable fire-door listings, egress, accessibility, and local access-control requirements before returning the opening to service.

Commercial Applications

Precision 2000 exit devices serving controlled-access commercial corridors, institutional entrances, school and university buildings, public facilities, office suites, and other security-monitored exits requiring a pushpad-based request-to-exit signal.
