Command Access MLRK1-MRK8 – Frequently Asked Questions

1) Will the Command Access MLRK1-MRK8 kit work on my Marks M8800 exit device?
That is exactly what the MLRK1-MRK8 is built for. It converts a mechanical Marks M8800 series device to motorized latch retraction, and the conversion keeps the device UL listed. It is a kit that goes into the existing device, not a new exit device, so the M8800 stays on the door.
2) What door widths does the MLRK1-MRK8 latch retraction kit fit?
36 inch and 48 inch doors. The one thing to check before ordering is filler plate: the device needs a minimum of 8.75 inches of filler plate for the kit to install properly. Measure the filler on the existing M8800 device, not the door, since that is the space the motor assembly occupies.
3) What voltage power supply do I need for a Command Access motorized latch retraction kit for Marks M8800?
24V, plus or minus 10 percent. The kit draws an average current peak of 900mA and holds at 215mA, so size the supply off the number of doors on it. There is built-in protection that shuts the system down above 28VDC, so an unregulated or over-spec supply will take the door offline rather than damage the motor.
4) How far can I run wire from the power supply to the MLRK1-MRK8 kit?
Up to 300 feet with 18ga wire. That is enough to put the power supply in a central IT or electrical room instead of above each opening, which is usually the difference between one supply for a corridor of doors and a transformer at every head.
5) Should I order the MLRK1-MRK8 with REX or the standard version?
Two versions are offered: standard, and with REX (request-to-exit). Order the REX version when the access control system needs to know the push pad was pushed, so it can shunt the door alarm or release a mag-locked pair on legitimate egress. If the panel does not need that signal, or you are picking up REX from another device on the opening, the standard kit is the one.
6) Can I use the MLRK1-MRK8 for electric dogging during business hours?
Yes, and it is rated continuous duty for it, so the door can sit dogged all day without cooking the motor. If someone pulls the push pad out of the dogged position, the kit auto re-engages rather than leaving the latch parked open.
7) What do I do if the latch does not fully retract after installing the Command Access kit on a Marks M8800?
Use the PTS electronic adjustment. It is a 5 second procedure that shifts latch position about 1/4 inch after the kit is already in the door, so a slightly off strike or a device that sits a hair proud does not mean pulling the assembly back out. The MM4S Smart Module also gives audible feedback for adjustment and power faults, which tells you whether you are chasing a mechanical position problem or a voltage problem.
8) The doors are heavy and the latch is binding. Is there a stronger setting on the MLRK1-MRK8?
There is a field-switchable High Torque mode for exactly that. It is a switch on the kit, not a different part number, so a stiff opening or a device under load can be handled at install without reordering. Normal current draw is a 900mA peak and 215mA hold.
9) Is a motorized latch retraction kit better than replacing the whole exit device with an electrified one?
A retraction kit like the MLRK1-MRK8 keeps the Marks M8800 device, the trim, and the door prep in place and electrifies what is already hung, so there is no re-prep and no rekeying of trim. Replacing the device means new hardware, new prep, and a new device on a door that was working. The kit route makes sense when the existing M8800 devices are sound and you are adding access control across a building; a full device swap makes sense when the mechanical devices are worn out anyway.
10) Is the Command Access MLRK1-MRK8 kit rated for commercial buildings like schools and hospitals?
It is a commercial-grade part, used in office buildings, schools, healthcare facilities, retail, industrial and warehouse space, multi-tenant residential, and government buildings. Combined with continuous duty electric dogging and a 300 foot wire run allowance, it suits facilities standardizing many openings on one central power supply.
