Command Access MLRK1-VD – Frequently Asked Questions

1) Will the Command Access MLRK1-VD fit my Von Duprin exit device?
The MLRK1-VD motorized latch retraction kit is built for Von Duprin 33/35 and 98/99 series exit devices, including their vertical rod configurations. If your device is a Von Duprin rim, mortise, or vertical rod unit in one of those two families, this is the kit. Anything outside 33/35 or 98/99 (another Von Duprin family, or another brand's device) is not what this kit is cut for.
2) What voltage and current does the MLRK1-VD motorized latch retraction kit need from my power supply?
Size the supply for 24 to 28 VDC, with a 900 mA peak draw at motor pull and 215 mA holding. The peak is brief inrush at retraction; the hold is what the circuit carries while the latch is held back. If you're running several openings off one supply, budget the peak per door, not the hold.
3) How far can I run wire from the power supply to a Command Access MLRK1-VD?
Up to 300 feet on 2-conductor 18 AWG. That distance is what lets you put the power supply and the access control panel in an electrical or IT room rather than in a cabinet above the door. The kit ships with a 6 inch Quick Molex connection and a 6 inch power lead at the device end, so the field splice happens right at the door.
4) Does adding a motorized latch retraction kit to a Von Duprin device void the fire or panic label?
The MLRK1-VD is built to preserve the fire and panic listings of the Von Duprin 33/35 or 98/99 device it goes into. That is the whole point of a listed retrofit kit versus a shop modification: the device keeps its label after the conversion.
5) Can I use the MLRK1-VD for electric dogging instead of just remote release?
Yes, and the dogging is continuous duty rated, so it can sit held open through a full business day without a duty cycle limit. It also re-engages on its own if someone pulls the push pad out of the dogged position, which is the failure that leaves a door unlatched overnight on lesser kits. Typical use is a schedule from the access control panel: dogged during hours, latched after.
6) Is the MLRK1-VD a whole new exit device or does it go into the one already on my door?
It's a retrofit kit, not a device. The MLRK1-VD installs into the Von Duprin 33/35 or 98/99 exit device already hung on the opening and converts it to electrified latch retraction. You keep the existing rail, push pad, trim, and rod hardware. For a property manager, that means the doors keep matching each other after the access control goes in.
7) How do I adjust the latch retraction timing after the kit is installed?
Push-to-Set handles it. One button, about a 2 second electronic set, and roughly 1/4 inch of adjustment range on the latch pull. You do it after the device is hung and closed, not on the bench, so the setting reflects the real door and frame. No shimming, no re-linking the drive.
8) What is the MM5 module in the Command Access MLRK1-VD and what does it do for troubleshooting?
MM5 is the smart module that drives the motor. It carries on-board diagnostics and audible feedback, so a tech at the door gets a signal telling them what state the kit is in rather than pulling a meter on the drive. Programming runs through a simplified sequence at the module. For an integrator maintaining a fleet of openings, that feedback is what keeps a service call to one trip.
9) Is the MLRK1-VD kit rated for commercial traffic or is it a light-duty product?
Commercial rated, and the electric dogging is continuous duty. It's specified into office buildings, schools, hospitals, retail, industrial plants, multi-tenant residential, and government facilities, which is the traffic profile a Von Duprin 33/35 or 98/99 opening already sees.
