Command Access MRC101EL 24V 626 – Frequently Asked Questions

1) What existing lock does the Command Access MRC104 retrofit chassis go into?
The MRC104 is a retrofit chassis built for Corbin Russwin 2000 Series mortise locks. You keep the existing mortise case location, trim and door prep, and swap in the electrified chassis to add electronic control. It is a chassis only, so the lock's trim, cylinder and other components stay with the door.
2) What does institutional function mean on an electrified mortise lock?
Institutional function means both levers are locked at the same time and both are released together electronically. There is no free egress lever on the inside when the lock is secure, which is why it shows up on detention-style, psychiatric and controlled-corridor openings. If you need the inside lever always free for egress, this is the wrong function and you want a storeroom or classroom function chassis instead.
3) Can I get the MRC104 chassis fail safe instead of fail secure?
Both are orderable. The MRC104 comes in fail-safe and fail-secure versions, each in 12V and 24V. Fail secure keeps the levers locked when power drops, which suits stairwells and secured storage. Fail safe releases the levers on power loss, which is what you use where the opening has to free up on a fire alarm or power failure. Pick the one that matches your access control sequence, because it is set by the chassis you order, not by a field switch.
4) What voltage and current draw should I size the power supply for?
The chassis runs on 12 or 24VAC/DC within plus or minus 10 percent. Draw is 700 mA at 12V or 350 mA at 24V, 8 watts total either way. A plug-in bridge rectifier ships with the lock, so you can feed it from an AC or a DC supply. If you are ganging several openings off one supply, 24V halves the per-door current and keeps the wire run easier.
5) What is the difference between the Command Access MRC104 and buying a complete electrified mortise lockset?
The Command Access MRC104 is a chassis-only retrofit part - it drops into an existing Corbin Russwin 2000 Series mortise lock so you reuse the case trim, levers and cylinder already on the door. A complete lockset such as the SDC Selectric 7800 PRO Series, a solenoid controlled mortise lock with a vandal resistant clutch, or the SDC 7600 Series Grade 1 motorized latch retraction lockset, ships as the whole lock and is the route when there is no compatible Corbin Russwin body in the door or the existing lock is worn out. Both SDC locksets are specified for 1-3/4 inch doors.
6) I need an electrified mortise lock for a Corbin Russwin 2000 Series door but I want both levers to release at once - what are my options?
The Command Access MRC104 is the chassis built for that requirement: it is a retrofit chassis for Corbin Russwin 2000 Series applications with institutional function, meaning the outside and inside levers are unlocked simultaneously by the electronic signal. Among the alternatives, the DynaLock EML-1 is a storeroom function electrified mortise lock, which controls the outside lever only and leaves the inside lever always free for egress. If your access control sequence needs both levers switched together, the MRC104 institutional function is the one that does it; if you only need the outside trim controlled, the EML-1 storeroom function is the simpler behavior.
7) My panic-hardware-free opening needs the latch pulled back on a signal, not just the lever unlocked. Is the MRC104 the right part?
No. The Command Access MRC104 is a solenoid-driven chassis that electronically unlocks the levers - the latchbolt stays projected and the door is opened by turning the lever. If you need the latch physically retracted on command, for example to release a door for an automatic operator, look at the SDC 7600 Series, which is a Grade 1 motorized latch retraction mortise lockset controlled at 24VDC. Latch retraction and lever unlocking are different functions, so confirm which one your access control sequence calls for before ordering.
8) Can the MRC104 be left energized continuously without burning out?
Yes. The chassis uses continuous duty solenoids rated for continuously on applications, so fail safe openings that sit powered all day, or doors held unlocked for long scheduled periods, will not overheat it.
9) Do I have to order the MRC104 handed?
No. Handing is field reversible on the MRC104 chassis, so one part covers left and right hand openings. That is useful if you are stocking spares for a building with doors swinging both ways.
10) Is the MRC104 heavy enough for a school or hospital corridor?
It is a Grade 1, heavy-duty commercial chassis, which is the top ANSI/BHMA durability tier for mortise locks and the level normally specified for schools, healthcare and government corridors. It is not a residential product.
11) What is the difference between this institutional function chassis and a storeroom function electrified mortise lock?
Institutional locks both levers together and releases both electronically, so the inside lever is controlled too. Storeroom function, like the DynaLock EML-1, keeps the inside lever free at all times and only controls the outside. Corridor and office doors that need free egress take storeroom; controlled openings where you must stop movement in both directions take institutional.
12) The opening does not need to be tied to an access control system - is there a straightforward mortise lock I should use instead of the MRC104?
Yes. The Command Access MRC104 is an electrified chassis that requires 12 or 24VAC/DC power and a controller to do anything. For an opening with no electronics, the Schlage L9050BDC is a mechanical Grade 1 heavy duty mortise entrance/office lock, single cylinder non-deadbolt function with a disposable SFIC core, for 1-3/4 inch doors. It gives you the same heavy duty mortise format without wiring, power supply or transfer hinge work.
13) My system only supplies 24VDC. Which electrified mortise options work on that?
The Command Access MRC104 chassis is dual voltage and runs on 12 or 24VAC/DC (+/- 10%), drawing 700 mA at 12V or 350 mA at 24V, and it ships with a plug-in bridge rectifier so either AC or DC power works; 12V and 24V variants are offered in 626 satin chrome. If you are specifying a complete lockset instead, the SDC 7600 Series is a 24VDC motorized latch retraction mortise lockset. The MRC104 is the more flexible choice if the power supply on the job may change.
14) We get abuse on this door - levers get yanked. Does the MRC104 address that?
The Command Access MRC104 is a heavy-duty Grade 1 commercial chassis with continuous duty solenoids, which addresses electrical duty cycle and general commercial wear rather than trim abuse specifically. If forced lever torque is the failure mode you are seeing, the SDC Selectric 7800 PRO Series is a solenoid controlled mortise lock built with a vandal resistant clutch, which is designed to let the lever turn free of the internal mechanism when locked. Note that the 7800 is a complete lockset for 1-3/4 inch doors, not a Corbin Russwin retrofit chassis like the MRC104.
15) For a school corridor standardization, should I spec the MRC104 chassis or the DynaLock EML-1?
It depends on the doors you already own and the lock behavior you want. The Command Access MRC104 is a Grade 1 retrofit chassis that converts existing Corbin Russwin 2000 Series mortise locks to electrified operation with institutional function - both levers switched together - and is field-reversible for handing, so one part number covers left and right hand openings. The DynaLock EML-1 is an electrified mortise lock with storeroom function, where the inside lever stays free. If your corridor doors already carry Corbin Russwin 2000 Series bodies, the MRC104 keeps the existing trim and cylinders in service across the fleet.
16) What finish does the MRC104 chassis come in?
626 satin chrome is the finish offered, across both voltages and both fail-safe and fail-secure builds. Since this is a chassis retrofit and the visible trim stays on the door, the existing lever and rose finish is what the opening will continue to show.
