Command Access MRC103EL 24V 626 – Frequently Asked Questions

1) Will the Command Access MRC105 retrofit chassis fit my existing Corbin Russwin 2000 Series mortise lock?
That is exactly what the MRC105 is built for. It is a retrofit chassis for Corbin Russwin 2000 Series mortise locks, so you reuse the existing mortise case pocket, trim and cylinder prep and swap the chassis to add electrified control. Storeroom function, so the outside lever is always locked until it is energized, and the inside lever always retracts the latch for egress.
2) Should I order the fail safe or the fail secure MRC105 chassis for my opening?
Both are orderable, and the choice is a life-safety and code call for the specific door. Fail secure keeps the outside lever locked when power drops, so the opening stays secure through an outage; that is the usual pick for storerooms, IT rooms and tenant suites. Fail safe releases the outside lever when power drops, which is what you want on doors tied into a fire alarm release or on a stair re-entry opening. The inside lever retracts the latch either way, so egress is never affected by the choice.
3) What voltage and current does the Command Access MRC105 mortise chassis draw, and will my existing power supply run it?
The chassis takes 12 or 24VAC/DC (+/- 10%) and pulls 8 watts, which works out to 700 mA at 12V and 350 mA at 24V. Size the supply off that per door and remember these are continuous duty solenoids, so on a fail safe door or an unlock-cycle application the current is drawn the whole time it is held, not just at the moment of release. A plug-in bridge rectifier comes with the lock, so an AC or a DC source both work without adding anything.
4) Which of these mortise options keeps the existing lock body in the door versus replacing the whole lockset?
Only the Command Access MRC105 is a chassis-level part: it is a retrofit chassis for the Corbin Russwin 2000 Series, supplied chassis only, so the existing mortise case and trim stay and the opening gains 12/24V electrified control. The comparables are complete locks -- the DynaLock EML-1 is an electrified mortise lock, the SDC 7600 is a motorized latch retraction mortise lockset, the SDC 7800 PRO is a solenoid controlled mortise lock, and the Schlage L9050BDC is a mortise entrance/office lock. For a property manager electrifying a handful of doors that already run Corbin Russwin 2000 Series hardware, the chassis route leaves the door prep and the trim alone; for openings with other hardware in them, one of the complete locksets is the path.
5) Is the Schlage L9050BDC a substitute for the Command Access MRC105?
No -- they solve different problems. The L9050BDC is a mechanical mortise entrance/office lock, single cylinder non-deadbolt function, Grade 1 heavy duty, for 1-3/4 inch doors, with a disposable SFIC core. There is no electrification in it. The MRC105 is an electrified chassis: 12 or 24VAC/DC operation at 8 watts with continuous duty solenoids, so an access control system can control the outside lever. The two also differ in function -- entrance/office on the Schlage versus storeroom on the MRC105, where the outside lever stays locked until power is switched. If the door is being wired to a reader or a release, the L9050BDC will not do it; if the door is staying mechanical, the electrified chassis is more hardware than the opening needs.
6) What should I use instead of the MRC105 if the opening needs latch retraction for a card reader release rather than lever control?
The SDC 7600 Series is the alternative for that opening. It is a Grade 1 motorized latch retraction mortise lockset with 24VDC control, so the latchbolt itself is drawn back on signal. The MRC105 works the other way: it is a fail secure storeroom chassis where switched power unlocks the outside lever and the lever then retracts the latchbolt, which means someone has to be at the door to turn it. Where the access control system needs to pull the latch on its own -- a remote release, an automatic operator sequence -- the motorized retraction of the 7600 is the function that does it. Note the 7600 is a complete lockset with a 1-3/4 inch door thickness, not a chassis dropped into existing Corbin Russwin 2000 Series hardware.
7) Do I need to specify handing when I order the MRC105 electrified mortise chassis?
No handing to specify. The MRC105 chassis is field reversible for left or right hand doors and no extra parts are needed to flip it, so one part number covers both swings. That is useful if you are ordering a batch across a building and do not want to survey every opening first.
8) Does the MRC105 come with a request-to-exit switch, or do I have to add it?
Request-to-exit is an option you select when ordering, not something included by default. Add it if your access control panel needs to see the inside lever being turned, which is the normal setup when the door is alarmed or monitored for forced and propped conditions. If the panel does not use REX on this opening, skip it.
9) Is the MRC105 heavy duty enough for a school or hospital corridor door?
Grade 1, heavy duty, commercial rated construction, which is the tier specified for high traffic institutional openings. Storeroom function suits the doors those facilities lock most often, classrooms held secure from the corridor side, med rooms, IT and mechanical spaces, where staff badge in from outside and anyone inside gets out on the lever.
10) Can the MRC105 be left energized all the time on a door I want held unlocked during business hours?
Yes, the solenoids are continuous duty and are built for continuously on applications, including fail safe holds and unlock cycles. Budget the power for it though: held at 12V that is 700 mA per door for the whole scheduled unlock window, 350 mA at 24V, so a multi-door schedule adds up fast on a shared supply.
11) What electrified mortise option holds up better on a door that gets the lever forced or wrenched?
The SDC Selectric 7800 PRO Series is the one built around that condition: it is a solenoid controlled mortise lock with a vandal resistant clutch, for 1-3/4 inch doors. The clutch is what absorbs force on the lever when the lock is in its secure state. The MRC105 is also solenoid driven and rated heavy-duty for commercial service with Grade 1 construction, but its answer to abuse is chassis strength rather than a clutch mechanism. On a stairwell, a service corridor, or a school entrance that sees the lever pulled hard, the 7800 addresses that directly. On a Corbin Russwin 2000 Series opening where the existing lock body and trim are staying, the MRC105 electrifies it without changing the lock case.
12) My access control panel only outputs 24VDC. Which electrified mortise locks work with that?
The MRC105 chassis covers it and gives you room either way: it runs on 12 or 24VAC/DC within plus or minus 10 percent, draws 8 watts, and ships with a plug-in bridge rectifier so the source can be AC or DC. Current draw is 700 mA at 12V and 350 mA at 24V, so the 24V side is the lighter load on the supply. The SDC 7600 Series is specified for 24VDC control, which suits a 24VDC-only panel but does not give a 12V fallback if the panel is later changed. The SDC 7800 PRO is solenoid controlled. Where a facility is standardizing supplies across a mix of openings, the dual-voltage MRC105 chassis lets the same part sit on 12V and 24V doors.
13) I need the door to unlock on a fire alarm signal. Does the MRC105 do that or do I need a different lock?
The MRC105 is offered in both fail-safe and fail-secure builds, so it can be ordered to unlock when power drops. Its solenoids are continuous duty, meant for continuously on applications including fail safe or unlock cycle operation, which is what a fail-safe door needs since it sits energized all day. Both options come in 12V and 24V. Among the alternatives, the DynaLock EML-1 is an electrified mortise lock in storeroom function, and the SDC 7800 PRO is solenoid controlled with a vandal resistant clutch. The choice comes down to whether the opening is a retrofit into Corbin Russwin 2000 Series hardware, where the MRC105 chassis keeps the existing lock body, or a full lock replacement.
14) Which mortise lock should I use if I want a small format interchangeable core so I can key it into my existing system?
The Schlage L9050BDC is the one that addresses keying directly: it is a single cylinder non-deadbolt entrance/office mortise lock supplied with a disposable SFIC, Grade 1 heavy duty in the L Series for 1-3/4 inch doors, so the disposable core comes out and your permanent small format core goes in. The Command Access MRC105 is a different kind of part -- a storeroom function electrified chassis for Corbin Russwin 2000 Series openings, sold as a chassis so the cylinder already in the door carries over rather than coming with the part. On a facility standardizing a keyway across doors, that distinction decides which one you order.
15) What finish does the Command Access MRC105 chassis come in?
626 satin chrome across every configuration, in both 12V and 24V and in both fail safe and fail secure. Since the chassis sits inside the mortise case, the finish that shows on the door is whatever Corbin Russwin trim and lever you keep, so a 626 chassis behind existing 626 or 630 trim will not change how the opening looks.
