Command Access MRC135WELCH 24V 626 – Frequently Asked Questions

1) Will the Command Access MRC135W fit my existing Best 35 Series mortise lock?
That is exactly what it is built for. The MRC135W is a retrofit chassis engineered for Best 35 Series mortise locks, so you reuse the existing lock case trim and cylinders and swap in an electrified chassis instead of replacing the whole lockset and re-prepping the door.
2) Can I order the MRC135W fail safe or fail secure, and can it be changed in the field?
Both are offered as ordering options, fail safe (EL) and fail secure (EU), and the configuration is field reversible along with handing. Fail safe unlocks on power loss, which is what most egress and fire-alarm-released openings call for; fail secure stays locked when power drops, which is the usual choice for security rooms.
3) What voltage and current does the MRC135W chassis draw, and will my power supply handle it?
It runs on 12 or 24VAC/DC within plus or minus 10 percent, with a plug-in bridge rectifier so you can feed it AC or DC. Draw is 700 mA at 12V or 350 mA at 24V, 8 watts total. Size the supply for that per opening, and note that 24V halves the current, which helps on long runs and multi-door supplies. Both 12V and 24V versions are ordered separately, so pick the one matching your panel.
4) What is the difference between the institutional function of the MRC135W and a storeroom function electrified mortise lock?
The Command Access MRC135W is institutional function: outside and inside levers are simultaneously locked or unlocked electronically, and the latchbolt is retracted by key from either side. A storeroom function electrified mortise lock such as the DynaLock EML-1 keeps the inside lever free for egress at all times and controls only the outside lever. Choose institutional where both sides must be controlled electrically, such as detention-style or secured patient areas, and storeroom where the inside must always release.
5) If the Best 35 Series lock body is being replaced entirely rather than retrofitted, what complete electrified mortise lockset can go in instead?
The Command Access MRC135W is a chassis-only retrofit that goes inside an existing Best 35 Series mortise lock. When the whole lock body is coming out, a complete electrified mortise lockset is the path: the SDC 7800 Series Selectric PRO is a solenoid controlled mortise lock with a vandal resistant clutch for 1-3/4 inch doors, and the SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset running on 24VDC. Both arrive as full locksets rather than an internal chassis, so the existing Best lock body is not reused.
6) Can this lock be left energized all the time without burning out?
Yes. The MRC135W uses continuous duty solenoids, rated for continuously on applications including fail safe operation and long unlock periods, such as a corridor door held unlocked through school hours.
7) What are the alternatives if my existing lock is not a Best 35 Series?
The MRC135W only retrofits Best 35 Series cases. For other openings, ZenSupply carries the DynaLock EML Series electrified mortise lock in storeroom function, the SDC 7600 Series Grade 1 motorized latch retraction mortise lockset for 1-3/4 inch doors, and the Schlage L9050BDC mortise entrance/office lock with disposable SFIC, also Grade 1 for 1-3/4 inch doors, where a mechanical lock will do.
8) Is this chassis rated for high traffic institutional use?
It is a Grade 1, heavy duty, commercial rated chassis, which is the level specified for hospitals, schools, government buildings and other high-cycle openings.
9) Does the MRC135W need to be ordered handed?
No. Handing is field reversible on the chassis, so one part covers left and right hand openings. What you do have to specify when ordering is voltage, 12V or 24V, and fail safe or fail secure.
10) Does a Schlage L9050BDC work as a substitute for the MRC135W?
No. The Schlage L9050BDC is a mechanical Grade 1 heavy duty mortise entrance/office lock for 1-3/4 inch doors with a single cylinder non-deadbolt function and disposable SFIC core; it has no electrical control. The Command Access MRC135W is an electrified chassis running on 12 or 24VAC/DC with fail safe or fail secure operation. The L9050BDC suits an opening that only needs mechanical key control, not one tied into access control.
11) For a door on a card reader that needs high-cycle latch retraction rather than lever control, what should be specified instead of the MRC135W?
The Command Access MRC135W controls the levers electronically and relies on continuous duty solenoids at 700 mA at 12V or 350 mA at 24V. Where the design calls for the latchbolt itself to be pulled back electrically, the SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset operating on 24VDC control for 1-3/4 inch doors. Motorized latch retraction moves the latch; the MRC135W leaves the latch mechanical and switches the lever control.
12) Which option holds up better against abuse in a school or correctional corridor, the MRC135W or the SDC 7800?
Both address abuse in different ways. The Command Access MRC135W is a Grade 1 heavy-duty chassis with continuous duty solenoids intended for institutional openings, and it reuses the existing Best 35 Series lock body and trim. The SDC Selectric 7800 PRO is a complete solenoid controlled mortise lock built with a vandal resistant clutch on 1-3/4 inch doors, so force on the lever is absorbed by the clutch. The MRC135W keeps the existing Best hardware in place; the 7800 replaces it.
13) What finish does the MRC135W come in?
626 satin chrome is the finish offered across all four fail safe/fail secure and voltage combinations. Since it is an internal chassis with the original Best trim staying on the door, the visible finish on the opening is whatever trim you already have.
14) Can the DynaLock EML-1 be used where a 12V supply is already run to the door?
The Command Access MRC135W runs on 12 or 24VAC/DC with a plug-in bridge rectifier, so an existing 12V supply feeds it directly, and it is offered in both 12V and 24V builds in fail safe and fail secure. The DynaLock EML-1 is an EML Series storeroom function electrified mortise lock; confirm its voltage against the supply already at the opening before substituting, since the function also differs from the institutional control of the MRC135W.
