Command Access MLRK1-CAL77 – Frequently Asked Questions

1) Will the Command Access MLRK1-CAL77 kit fit my Cal-Royal 7700 exit devices?
The MLRK1-CAL77 is built specifically for Cal-Royal 77 and PD26 series devices, and it covers both the 36 inch device (with a 3.75 inch cutdown) and the 48 inch device. If your openings are running Cal-Royal 77 or PD26 push pads, this is the kit that electrifies them. Anything from another exit device manufacturer needs a different Command Access kit, since the retraction hardware mounts to the Cal-Royal activating bracket.
2) What power supply do I need for a motorized latch retraction kit on a Cal-Royal 7700?
Size the supply for 22 to 28 VDC. In standard mode the MLRK1-CAL77 draws 190mA holding and 900mA peak. If you field-switch the MM4S module to high torque mode, budget 250mA hold and 2A peak per device, which is what matters when you are putting several doors on one supply. Wire runs up to 300 feet with 2-18ga wire are supported, so the supply can sit in a central closet rather than above each opening.
3) Does electrifying a Cal-Royal exit device with a retraction kit void its UL listing?
No. The MLRK1-CAL77 retrofit is built so the existing UL listings on the original exit device stay intact after installation. That is the difference between a kit like this and a shop-built modification, and it is the point an AHJ will ask about on a fire-rated opening.
4) Should I buy the standard MLRK1-CAL77 or the REX version?
Two build options ship: standard, and one with REX (request-to-exit). Take the REX version when the access control system needs to know the push pad was used, to shunt an alarm or release a mag on egress. If the door is only being pulled in by a card reader or a scheduled unlock and nothing downstream cares about mechanical egress, the standard kit is enough.
5) Can I use a motorized latch retraction kit for electric dogging during business hours?
Yes, electric dogging is one of the functions. The MLRK1-CAL77 is continuous duty rated so it can hold the latch retracted all day, and it auto re-engages if someone pulls the push pad out of the dogged position. That gets you a scheduled push-pull opening in the morning and a secured latch at close without anyone walking the building with a dogging key.
6) How much of the door and frame has to be cut to install a Cal-Royal latch retraction kit?
Very little. The unit secures to the back activating bracket with two screws, and only one hole is needed for the wire raceway. There is no chassis swap and no new device to hang, which is why this route is usually taken instead of buying a factory electric-latch-retraction exit device and re-prepping the opening.
7) How do you adjust a Command Access MM4S latch retraction module after it is installed?
The MM4S Smart Module uses PTS, Push to Set: a 5-second electronic adjustment that sets latch position without taking the device apart. It also runs on-board diagnostics with audible feedback, so an adjustment problem or a power problem announces itself instead of being chased with a meter. On a callback that is the difference between a five minute trip and pulling the cover off.
8) Is a motorized latch retraction kit the right choice, or should I replace the exit device outright?
Converting is the cheaper path when the mechanical device is sound. The MLRK1-CAL77 turns an existing mechanical Cal-Royal 77 or PD26 into an electrified latch pullback device, mounting to hardware already on the door and keeping the original UL listings. Replace the device instead when it is worn out, when the opening is not a Cal-Royal 77 or PD26, or when the device length is something other than the 36 inch or 48 inch sizes this kit is built for.
9) Is the MLRK1-CAL77 kit rated for commercial traffic like schools and hospitals?
It is a commercial-duty product, and the retraction motor is continuous duty rated for held-open dogging. Typical placements are school and healthcare entries, retail, government buildings and multi-tenant properties, where the exit device has to stay under access control all day and still free-egress mechanically.
