Command Access MLRK1-AREX – Frequently Asked Questions

1) Will the Command Access MLRK1-AREX motorized latch retraction kit fit an Adams Rite EX series exit device I already have installed?
That's exactly what the MLRK1-AREX is built for. It's a field-installable motorized latch retraction kit for Adams Rite EX series exit devices, sized to fit inside all Adams Rite EX devices with no clearance issues thanks to the custom ball screw assembly and stepper motor package. It covers 36 inch and 48 inch EX devices, and it can be cut down to pushpad level for shorter openings. It will not go into any other manufacturer's device.
2) What voltage and current does a motorized latch retraction kit for Adams Rite EX devices need from the power supply?
The MLRK1-AREX runs on 22 to 28 VDC. In standard mode it draws 1.3A peak and 170mA hold. There's a field-switchable High Torque mode that raises that to 2A peak and 250mA hold for openings that need more pulling force, so size the supply for the mode you plan to run. Budget your amperage per leaf when you're feeding several doors off one supply.
3) How far can I run wire from the power supply to a Command Access MLRK1 latch retraction kit?
Up to 300 feet with 2-conductor 18ga wire. That's what lets you put the power supply in an electrical or IT room instead of above each opening, which is usually the difference between one central supply and a transformer over every door. The MM4 module lands with an 8 foot cable and a Molex quick connect for the power supply lead.
4) Do I need the REX version of the MLRK1-AREX, or the standard one?
Two versions are ordered: standard, and with REX (request-to-exit). Take the REX version when the access control system needs to know the pushpad was pressed, to shunt an alarm or release a door held by the system on egress. If the panel doesn't monitor egress at this opening, the standard kit is all you need. REX is built into the kit at the factory, so it's an order-time decision, not something added later.
5) Is the MLRK1-AREX a whole new exit device or just the electrification kit?
It's the kit only, a replacement/retrofit assembly that goes inside an Adams Rite EX exit device you already have or are buying separately. You're getting the ball screw assembly, stepper motor, MM4 module and cable, not a device, not trim, and not a power supply. Plan on a 22 to 28 VDC supply and the wire run as separate line items.
6) Can motorized latch retraction be used for scheduled electric dogging on a school or office entrance?
Yes. The MLRK1-AREX includes a continuous duty rated electric dogging function, so you can hold the latch retracted through business hours on a timer or access control schedule without duty-cycle worry. It also auto re-engages if the push pad is pulled from the dogged position, so a tugged door doesn't leave the opening in a half state.
7) How do I adjust a Command Access MLRK1 kit after it's installed if the latch isn't fully retracting?
There's a PTS (Push to Set) routine: a 5 second electronic adjustment with roughly 1/4 inch of range, so minor travel errors get dialed out without pulling the device off the door. The MM4 smart module also gives audible feedback on adjustment and power problems, so the beep tells you whether you're chasing travel or chasing voltage at the end of a long wire run.
8) Can I put a motorized latch retraction kit on a 42 inch Adams Rite EX device, or does it only come in fixed lengths?
The MLRK1-AREX is supplied for 36 inch and 48 inch Adams Rite EX devices and can be cut down to pushpad level, so an in-between opening is handled by cutting the longer kit rather than ordering a special length. Match the kit to the device size you're starting from and trim from there.
9) Is this latch retraction kit rated for commercial traffic in a hospital or campus building?
It's a commercial-duty product, and the electric dogging is continuous duty rated, which is what matters on an entrance that stays unlocked all day. The MM4 module's on-board diagnostics give you a local indication when power or adjustment drifts, useful when the opening is one of many across a campus and nobody is watching it daily.
