Command Access MLRK1-COR Motorized Latch Retraction Kit for Corbin Russwin 4/5000 & Yale 7000 Series with Smart Module Technology

Professional Exit Device Electrification Solution

The Command Access MLRK1-COR Motorized Latch Retraction Kit provides a high-quality, cost-effective method of converting Corbin Russwin 4/5000 & Yale 7000 series exit devices to electrified motor-driven latch retraction systems. Operating on 24 to 28 VDC with low current draw (215mA standard hold, 250mA high torque hold), this kit features Patent Pending Push to Set (PTS) Technology for easy post-installation adjustment and supports wire runs up to 300' with 18ga wire. The system includes the innovative MM4S Smart Module with on-board diagnostics and audible feedback for enhanced troubleshooting capabilities.

Professional Features & Benefits

  • Device Cutdown Specifications: 36" devices require 4" cutdown from end cap, 48" devices require 10" cutdown from end cap for proper installation.
  • Extended Wire Run Capability: Supports up to 300' wire runs with 18ga wire, allowing centralized power supply placement for convenient installation.
  • Dual Torque Operation: Field switchable between standard torque (900mA peak, 215mA hold) and high torque mode (2A peak, 250mA hold) for demanding applications.
  • Smart Module Technology: MM4S Smart Module provides on-board diagnostics with audible feedback for adjustment and power issues, simplifying troubleshooting.
  • Patent Pending PTS Technology: Push to Set feature allows 5-second electronic adjustment with approximately 1/4" range for easy post-installation fine-tuning.
  • Complete Latch and Push Pad Retraction: Retracts both latches and push pad, allowing electronically dogged devices to remain in push/pull state for extended periods.
  • Continuous Duty Rating: Electric dogging rated for continuous operation with auto re-engage if push pad is pulled from dogged position.
  • Manufacturer Warranty: 3-year "no-hassle" warranty for added confidence and protection.

Command Access MLRK1-COR – Frequently Asked Questions

1) Will the Command Access MLRK1-COR motorized latch retraction kit work on my Corbin Russwin exit devices?
The MLRK1-COR is built for Corbin Russwin 4/5000 series and Yale 7000 series exit devices. It converts those devices to motor-driven electric latch retraction, retracting both the latch and the push pad. If your openings carry a different manufacturer's device, this is the wrong kit; Command Access builds the MLRK line model-specific, so match the kit to the device family already on the door.
2) What voltage and current does the MLRK1-COR latch retraction kit draw, and can I run it off a shared access control power supply?
Power it with 24 to 28 VDC. Standard torque mode pulls 900mA peak and 215mA hold; switch it to high torque and it pulls 2A peak, 250mA hold. Size the supply on peak, not hold, and remember every device on that supply may pull at once on a fire alarm release or a scheduled unlock. Wire runs up to 300 feet with 18ga are supported, so the supply can sit in a central closet rather than above the door.
3) Do I have to cut down the exit device to install a Command Access MLRK1 motor kit?
Yes, and the amount depends on device length. A 36 inch device takes a 4 inch cutdown from the end cap; a 48 inch device takes a 10 inch cutdown from the end cap. Plan for that before you pull the device off the door, because the cut is permanent and it has to be made to the correct dimension for the motor assembly to seat.
4) What is the difference between the standard MLRK1-COR and the REX version?
Two configurations are offered: standard, and with REX (request-to-exit). The REX version signals the access control system when someone pushes the pad from the inside, which is what shunts the door alarm and logs a legitimate egress. If your panel needs a REX input at that opening, order the REX version at the outset, since the signaling hardware is part of the kit rather than a field add-on.
5) Can I use motorized latch retraction for all-day electric dogging on a school or retail entrance?
That is what it is for. The kit is rated for continuous duty, so an electrically dogged device can sit in push/pull state for extended periods, such as building open hours. If someone pulls the push pad out of the dogged position, it auto re-engages rather than staying out of sync with the panel.
6) Why choose motorized latch retraction instead of an electric strike on an exit device opening?
An electric strike releases the door at the frame and leaves the exit device latched, so it does nothing for a pair of doors or for push/pull dogging. Motorized latch retraction works inside the device itself, pulling the latch and the push pad back so the opening is genuinely free-swinging for card access or scheduled unlock. On an existing Corbin Russwin 4/5000 or Yale 7000 device, the MLRK1-COR electrifies what is already hanging there instead of requiring frame work.
7) How do you adjust a Command Access MLRK1 kit after it is installed in the door?
Patent pending Push to Set does it electronically: hold for about 5 seconds and the motor resets its stroke, with roughly 1/4 inch of adjustment range. That covers the drift you get after the device is remounted or the door settles, without pulling the cover and mechanically re-shimming the assembly.
8) My motorized latch retraction kit is not retracting fully. How do I troubleshoot the MLRK1-COR?
The MM4S Smart Module included with the kit runs on-board diagnostics and gives audible feedback that separates an adjustment problem from a power problem, so you know whether to run Push to Set or go check voltage drop on the run. If it is a torque complaint on a heavy or high-traffic door, the module is field switchable to high torque mode, which raises the pull to 2A peak and 250mA hold.
9) Is the Command Access MLRK1-COR kit rated for commercial use, and where does it typically get installed?
Commercial rated, and the usual homes for it are schools, healthcare corridors, retail entrances, government buildings, and industrial facilities where an exit device has to unlock on a card read or a time schedule. It is a replacement part that electrifies an existing device, not a complete exit device, so the Corbin Russwin 4/5000 or Yale 7000 device has to already be on the door.
