Command Access MRC135DEU 24V 626 – Frequently Asked Questions

1) Is the MRC135D a complete mortise lock or just the chassis?
Chassis only. The MRC135D is the electrified guts that drop into an existing Best 35 Series mortise lock case, not a full lockset. If you're starting from a bare door with no mortise lock in it, this isn't the part - you'd want a complete electrified mortise lockset such as the SDC 7800 PRO Series solenoid controlled mortise lock or the SDC 7600 Series with motorized latch retraction.
2) Do I order the MRC135D fail safe or fail secure?
Both are offered as ordering options, and the chassis is field-reversible between fail safe (EL) and fail secure (EU), so a wrong call on the order form is fixable on site. Fail safe unlocks the outside lever when power drops - that's what you use where the door has to release on a fire alarm or power loss. Fail secure keeps the outside lever locked without power, which is the usual choice for stairwell-side, storage and IT rooms where you don't want the door opening itself during an outage.
3) Can the MRC135D run on my 24V access control power supply?
Yes, and on 12V as well. The chassis takes 12 or 24VAC/DC within +/- 10 percent and includes a plug-in bridge rectifier, so an AC or DC supply both work. Current draw is 700 mA at 12V and 350 mA at 24V, 8 watts either way - worth doing the math on before you hang several of these off one supply. Voltage is an ordering option, so pick the one matching your panel.
4) I need electrified mortise locks but my existing hardware isn't Best - what are my options?
The MRC135D only retrofits Best 35 Series cases, so on other brands you're replacing the whole lock. Complete electrified mortise locksets worth looking at are the DynaLock EML Series in storeroom function, the SDC 7800 PRO Series with a vandal resistant clutch, and the SDC 7600 Series with motorized latch retraction, both SDC models listed for 1-3/4 inch doors.
5) Can I use the Command Access MRC135D on a mortise lock that is not a Best 35?
No. The MRC135D chassis is engineered as a retrofit specifically for Best 35 Series mortise locks, and the fit and function depend on that case. For an opening with a different mortise lock, a complete electrified lockset is the way to go: the DynaLock EML-1 covers storeroom function as an electrified mortise lock, and the SDC Selectric 7800 PRO Series is a solenoid controlled mortise lock for a 1-3/4 inch door. Both replace the lock rather than retrofitting into one.
6) What is the difference between the Command Access MRC135D and a complete electrified mortise lockset like the SDC 7800?
The MRC135D is a retrofit chassis, not a complete lock. It is built to drop into an existing Best 35 Series mortise lock and electrify it with 12 or 24VAC/DC storeroom operation, so the existing case, trim, and cylinder stay in the door. The SDC Selectric 7800 PRO Series is a full solenoid controlled mortise lock with a vandal resistant clutch, supplied as a complete lockset for a 1-3/4 inch door. If the Best 35 mortise case is already hung and in good condition, the retrofit chassis is the path that keeps the existing hardware; if the opening is new or the existing case is being replaced outright, a complete lockset such as the 7800 is the one to spec.
7) What is the closest electrified storeroom mortise lock to the Command Access MRC135D from another brand?
The DynaLock EML-1, from the EML Series, is an electrified mortise lock in storeroom function, the same function the MRC135D provides. The difference is scope: the MRC135D is a retrofit chassis engineered for Best 35 Series mortise locks with field-reversible fail safe or fail secure operation on 12 or 24VAC/DC, while the EML-1 is supplied as an electrified mortise lock in its own right. For a Best 35 opening being electrified in place, the MRC135D matches the existing case; for an opening being fitted with a new electrified mortise lock, the EML-1 covers the same storeroom function.
8) I need latch retraction for an access control release, not a lever release. Is the MRC135D the right part?
No. The MRC135D is a storeroom function chassis: the solenoid locks or unlocks the outside lever electrically while the inside lever stays free for egress, and the latch stays projected. The SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control, which physically retracts the latch on command for remote release and for holding an opening in a pulled-back state. Where the sequence of operation calls for latch retraction, the 7600 is the one to specify; where it calls for electric lever control, the MRC135D does that job on a Best 35 case.
9) Can this electrified mortise chassis stay energized all day for a scheduled unlock?
It can. The MRC135D uses continuous duty solenoids, so holding it energized for an unlock schedule or running it fail safe where it sits powered most of the time won't cook it. That matters on lobby and corridor doors that unlock for business hours.
10) What does storeroom function mean for egress on a door with the MRC135D?
Inside lever is always free. The outside lever is what gets locked or released electrically, so anyone inside can leave at any time regardless of what the access control system is doing or whether power is present. That's the arrangement code officials expect on an egress door.
11) Is the MRC135D heavy enough for a high-traffic commercial opening?
It's 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 office corridor doors. Among comparable electrified mortise products, the SDC 7600 Series and the Schlage L9050BDC are also Grade 1 if you need a full lockset rather than a retrofit chassis.
12) Can I standardize a building's Best 35 mortise locks on the MRC135D?
Yes, if the openings are storeroom function. One part number covers every Best 35 Series door you want to bring under access control, and because fail safe and fail secure are field-reversible, a single stocked configuration can serve both your egress-release doors and your locked-on-power-loss doors. Keep voltage consistent with whatever panels you already run.
13) Does the MRC135D change how the door is keyed or cylinder prepped?
No. It's the electrified chassis going into the existing Best 35 Series case, so the cylinder, keyway and keying on that lock carry over unchanged. What changes is that the outside lever now answers to your access control system as well as the key.
14) If the opening does not need to be electrified, what mortise lock replaces the Command Access MRC135D?
Nothing electrified is required for a mechanically locked opening. The Schlage L9050BDC is a Grade 1 heavy duty mortise lock in entrance/office function, single cylinder non-deadbolt, with a disposable SFIC core and a 1-3/4 inch door thickness, from the L Series. It is a purely mechanical lockset with no solenoid, no power supply, and no access control tie-in. The MRC135D only makes sense when the outside lever has to be controlled electrically at 12 or 24VAC/DC from an access control system; where the lock is keyed and operated by hand, the L9050BDC covers the opening without any of the wiring.
15) Is the Schlage L9050BDC a substitute for the Command Access MRC135D storeroom function?
They are different functions, so one does not stand in for the other. The MRC135D is storeroom function: the outside lever is locked and requires a key or an electric release, and it never stays unlocked by mechanical means. The Schlage L9050BDC is entrance/office function, single cylinder non-deadbolt, in the Grade 1 L Series. Entrance/office allows the outside lever to be set unlocked and left that way, which is why it does not meet a storeroom specification on a stock room, mechanical room, or any door that must self-relock behind every user.
16) The door is 1-3/4 inch and takes a lot of abuse. Which electrified mortise option holds up?
For a high-abuse opening the MRC135D is Grade 1 heavy-duty and runs continuous duty solenoids, so it tolerates being held unlocked for long periods without overheating, but it depends on the existing Best 35 mortise case and its trim to take the physical abuse. The SDC Selectric 7800 PRO Series is a solenoid controlled mortise lock with a vandal resistant clutch built into the lock itself and fits a 1-3/4 inch door, which puts the abuse resistance in the new hardware rather than in what is already hung. The SDC 7600 Series is Grade 1 as well and also fits 1-3/4 inch. Choose on whether the existing Best 35 case is being kept.
17) Our access control panel is 24VDC only. Which mortise lock options work on that supply?
The MRC135D takes either 12 or 24VAC/DC and is ordered as a 12V or 24V chassis, so a 24VDC panel is a direct match. The SDC 7600 Series motorized latch retraction lockset is specified with 24VDC control, so it also suits a 24V-only supply, though it retracts the latch rather than releasing the lever. Between the two, the deciding factor is the sequence of operation the panel is driving, not the supply voltage, since both accept 24V.
18) What finish does the MRC135D retrofit chassis come in?
626 satin chrome, across all four fail safe / fail secure and voltage combinations. Since it's a chassis living inside the lock case, the visible trim on the door stays whatever your existing Best 35 hardware is.
19) Do I have to decide fail safe or fail secure before ordering, the way I would with a complete electrified lockset?
The MRC135D chassis is field-reversible between fail safe (EL) and fail secure (EU), so the operation can be set on site to match the code requirement for the opening. The chassis is still ordered as a fail-safe or fail-secure configuration in 626 satin chrome at 12V or 24V. Compared with specifying a complete electrified lockset such as the DynaLock EML-1 storeroom electrified mortise lock or the SDC Selectric 7800 solenoid controlled mortise lock, the reversibility is what lets a stocking locksmith carry one chassis and settle the fire and egress question at the door.
