Command Access MLRK1-DOR – Frequently Asked Questions

1) Does adding a motorized latch retraction kit to a Dorma exit device void the UL listing?
No. The MLRK1-DOR is designed to convert a mechanical Dorma 9000 device to electrified latch pullback while maintaining the device's UL listing, which is the whole point of using a purpose-built retraction kit rather than a shop-fabricated solenoid. For an institutional or healthcare facility that has to keep listed hardware on a rated opening, that matters more than the cost difference.
2) What power supply do I need for a Command Access MLRK1-DOR latch retraction kit?
24VDC, and size the supply for inrush, not hold. In standard mode the kit draws 900mA peak and settles to 215mA hold current. Switched to high torque mode in the field it pulls 2A peak and 250mA hold. Spec the supply off the peak figure for every device on the circuit, then the hold current tells you what it actually sits at once the latches are retracted, which is what matters on a device dogged open all day.
3) When would I switch the MLRK1-DOR to high torque mode?
High torque mode is the field-switchable setting for openings where the device needs more force to pull the latches, typically stiffer or heavier hardware and doors under load. It raises the draw from 900mA peak / 215mA hold to 2A peak / 250mA hold, so if you set devices to high torque you have to account for that on the power supply budget. The switch is on the kit, so you can start in standard mode and change it on site if retraction is sluggish.
4) Can a motorized latch retraction kit be used for all-day electric dogging on a Dorma 9000?
Yes, the MLRK1-DOR is rated for continuous duty electric dogging, so it can hold the latches retracted through business hours without duty-cycle limits. It also auto re-engages if someone pulls the push pad while the device is dogged, so the opening does not sit unsecured after a pull. That is the behaviour you want on a retail or office entry that runs free-access during the day and secures on a schedule.
5) How do I adjust the latch position after installing a Command Access latch retraction kit?
The kit uses PTS electronic adjustment: a 5-second routine done after the kit is in the device, giving roughly 1/4 inch of latch positioning range. So you do not have to pull the device back off the door to dial in retraction, which is what turns a return trip into a five-minute fix when the latch is not clearing the strike cleanly.
6) Is the MLRK1-DOR a whole new exit device or just the retraction hardware?
It is a replacement-parts kit, not an exit device. You buy it to electrify a Dorma 9000 Series device you already have on the door, so the existing device, trim and door prep stay in place. If the opening has no 9000 Series device on it yet, this kit is not what completes the job.
7) How do I troubleshoot a motorized latch retraction kit that isn't retracting?
The MLRK1-DOR carries an MM4S Smart Module with on-board diagnostics and audible feedback, so the kit itself signals adjustment problems and power problems rather than leaving you to meter the run blind. Given the 300 foot limit on 18ga wire and the 2A peak draw in high torque mode, undersized supply and voltage drop on a long run are the two things to check first when a device is slow or intermittent.
8) What wiring comes with the Command Access MLRK1-DOR kit?
The kit ships with a 6 inch Molex pigtail at the device end plus a 6 foot power lead to get you to the transfer point. You still supply the run back to the 24VDC supply and the power transfer device (hinge or door loop), which are not part of the kit.
