Command Access MLRK1-DRX – Frequently Asked Questions

1) Will the Command Access MLRK1-DRX motorized latch retraction kit work on my Dorex exit devices?
The MLRK1-DRX is built specifically for Dorex 9500 series exit devices. It converts a mechanical 9500 to electrified latch pullback. If your openings carry a different brand or a different Dorex series, this is the wrong kit, Command Access builds device-specific MLRK kits and the one matched to your exact device is what you need.
2) How far can I run wire from the power supply to a Command Access MLRK1 latch retraction kit?
Up to 300 feet with 18ga wire. That is what lets you put the power supply in a central electrical room or closet instead of near each opening. The kit itself ships with an 8-foot cable and a Quick Connect at the MM4S module, so the field splice happens at the end of your home run, not inside the device.
3) Can the MLRK1-DRX kit be cut down for a 36 inch or 48 inch door?
Yes, the kit supports cutdown for 36 inch and 48 inch doors all the way to the pushpad. That matters because a 9500 device sized to a narrower opening still gets a full-length retraction assembly, and you trim it in the field rather than ordering a length-specific part.
4) Does the Command Access MLRK1-DRX give me electric dogging as well as latch retraction?
Both. The kit adds electric dogging rated for continuous duty, so you can hold the latch retracted through business hours without a duty-cycle limit. If someone pulls the push pad while it is dogged, the device auto re-engages, which means a door left in classroom-hours mode relocks on the first manual pull instead of staying open.
5) Can I electrify existing Dorex 9500 exit devices instead of replacing them?
That is exactly what the MLRK1-DRX does. It is a retrofit kit that converts a mechanical Dorex 9500 to electrified latch pullback, so the device, the door prep, and the strike stay as they are. For a property manager standardizing a building, that means the openings keep matching visually and only the electrical work is new.
6) How do I adjust latch pullback on the MLRK1 kit after the device is already installed on the door?
Push to Start (PTS) technology handles it: a 5-second electronic adjustment with roughly 1/4 inch of range, done after installation. No pulling the device off the door to shim or re-set the mechanical stroke. The MM4S smart module also gives audible diagnostic feedback for adjustment and power problems, so a bad adjustment or a sagging supply tells you what it is instead of just failing to retract.
7) What is the difference between standard and high torque mode on a Command Access motorized latch retraction kit?
It is a field-switchable setting on the kit, not two different part numbers. Standard mode draws 900mA peak and 215mA hold. High torque mode draws 2A peak and 250mA hold, and it is what you switch to when the device needs more force to pull the latch, typically a heavier or tighter opening. Set it in the field after you see how the door behaves, but budget power for high torque if there is any chance you will need it.
8) Is motorized latch retraction better than a solenoid kit for a Dorex 9500 on an access control opening?
Motorized retraction is the choice where the device cycles frequently or has to stay retracted, which is why the MLRK1-DRX is rated continuous duty for dogging. Solenoid pullback is a momentary function and is not intended to be held. If your Dorex 9500 openings are tied to card readers with scheduled unlock periods, or to a fire alarm interface that holds latches retracted, motorized is the one that survives the duty.
9) What else do I need to order besides the MLRK1-DRX kit to finish an electrified exit device opening?
The kit brings the motor assembly, the MM4S module, and an 8-foot cable with Quick Connect. What it does not bring is the 24 to 28 VDC power supply sized for your peak draw, the home run wire (18ga gets you 300 feet), and whatever transfers power from frame to door, a door loop or an electric hinge. Your access control relay or fire alarm interface is separate as well.
10) Is the MLRK1-DRX rated for commercial use in schools, hospitals, and government buildings?
It is a commercial-duty kit, and the application list runs to educational facilities, healthcare institutions, government and municipal buildings, offices, retail, industrial and warehouse, and multi-tenant residential. The continuous duty electric dogging is the part that matters in those facilities, since scheduled unlock during occupied hours is the normal mode of operation.
