The Command Access Technologies Request-to-Exit (REX) Switch Retrofit Kit adds an electrical monitoring signal to compatible Adams Rite 8400, 8600 and 8800 Series commercial exit devices. Designed for field installation, this switch detects operation of the exit-device pushpad from the secured side of the opening and sends a signal to a connected access-control or security panel. It allows the door's normal mechanical egress action to be monitored without installing a separate wall-mounted request-to-exit button.

REX Signal Integration and Compatibility

The ARREXKIT-ED is intended to add an electrical request-to-exit event indication to approved Adams Rite 8400, 8600 and 8800 exit devices. It is a monitoring accessory rather than an electrification or latch-retraction kit; it does not independently retract the latch or unlock the door.

• Fit check: Identify the exact device series, internal mechanism and available switch mounting location. Follow the manufacturer’s current retrofit instructions rather than assuming all Adams Rite versions use identical switch locations.
• Contact integration: Map the specified switch terminals to the controller’s REX input and verify input type, contact state and any egress shunt timing.
• Verification: Test REX actuation during normal pushpad operation, switch reset on release and uninterrupted manual egress.

This ARREXKIT-ED model is intended for compatible mechanical or solenoid-operated Adams Rite exit devices. Motorized Adams Rite exit devices require a different Command Access REX kit, such as the ARREXKIT-M-ED, as specified in the manufacturer compatibility matrix.

Key Features and Benefits

• Dedicated Adams Rite compatibility: Designed for compatible Adams Rite 8400, 8600 and 8800 Series exit devices. Always identify the existing hardware and verify installation clearances before ordering.
• Request-to-exit monitoring: Detects interior pushpad operation and provides a control-panel signal to record an exit event or coordinate an approved access-control sequence.
• Field-installable retrofit: Adds a REX switch to supported existing exit devices, often without replacing the complete panic bar or adding a standalone door-side sensor.
• SPDT contact design: The single-pole, double-throw switch provides common, normally open and normally closed contacts for compatible panel input configurations.
• Simple three-wire connections: The manufacturer's installation sheet identifies green = common (C), blue = normally open (NO), and gray = normally closed (NC).
• Works with supported mechanical and solenoid exit devices: The Command Access application matrix approves this kit for mechanical and solenoid-operated Adams Rite devices, not its separately designated motorized versions.
• Low-voltage security interface: Supports monitored exiting as part of a properly designed security and access-control installation. The REX switch is a signal contact, not a standalone electrified lock, release controller or power supply.
• Commercial-use accessory: Useful for commercial doors, retail storefronts, offices, institutional facilities and other openings equipped with approved Adams Rite panic hardware.
• Manufacturer warranty: Command Access publishes a three-year limited warranty for its REX exit-device switch kit family; confirm current terms and installation requirements.

Technical Specifications

How the Request-to-Exit Switch Works

When an occupant presses the inside panic bar, the REX switch changes contact state. A connected controller can interpret the NO or NC contact transition as an authorized exit request or recorded exit event. This signal can be used by a suitably designed access-control system to coordinate unlocking or temporarily suppress a door-forced alarm while the door opens. The REX switch itself does not unlock the door, retract the latch, energize a solenoid or provide access-control logic.

Installation Overview

1. Confirm compatibility: Match the existing Adams Rite 8400, 8600 or 8800 device and determine whether it is mechanical, solenoid-operated or motorized. Do not substitute this model for the motorized REX kit.
2. Prepare the device: Follow the official Command Access instructions to remove the pushpad/cover and locate the manufacturer-designated switch mounting location.
3. Route the switch conductors: Fish the wires through the prescribed exit-device holes and route the wiring through an approved door power-transfer path to the monitoring equipment.
4. Mount the switch: Use the provided or manufacturer-specified self-tapping screws to position the REX assembly so it reliably changes state as the pushpad operates.
5. Terminate the contacts: Wire green to common, blue to normally open and gray to normally closed as required by the controller input. Verify rating and polarity requirements of the overall low-voltage control circuit.
6. Test before closing: Check continuity at the released and pressed pushpad positions. Verify the monitoring panel receives the appropriate exit event, then replace the device cover.
7. Verify the complete opening: Test free mechanical egress, proper latching, alarm coordination and any fire-rated-door or life-safety requirements.

Typical Applications

Security-monitored commercial storefront entrances, institutional exit doors, schools, office suites, healthcare administrative spaces and other access-controlled openings where a compatible Adams Rite exit device needs pushpad-based request-to-exit monitoring.

Package and Ordering Notes

Included: One factory-specified Command Access ARREXKIT-ED retrofit switch kit for supported Adams Rite exit devices. Manufacturer and distributor documents identify a switch assembly, mounting screws, wiring accessories, labeling and/or installation instructions; confirm current carton contents for the supplied revision.

Not included: Adams Rite exit device/panic bar, access controller, separate electrified latch-retraction system, wiring transfer, external power supply or motorized-device REX conversion kit. This is one field-installable monitoring switch accessory, not a complete exit-device system.
