Command Access ML453DEL 3H 626 24V – Frequently Asked Questions

1) Is the Command Access ML453D a complete lockset or just the chassis?
The ML453D is an electrified Best 45H series mortise lock chassis. Trim is a separate ordering choice, with 3H, 14H and 15H lever trim available, and the finish is 626 satin chrome. Plan on specifying the cylinder and any strike separately, since what you are buying is the electrified chassis and the trim you select with it.
2) Can I retrofit a Best 45H mortise lock with the ML453D without changing the door prep?
Yes. The ML453D is built on the Best 45H series mortise platform, so it drops into an existing 45H pocket and prep. You are swapping a mechanical chassis for an electrified one, so the new work is pulling power to the door, not routing the mortise.
3) Should I order the ML453D fail safe or fail secure?
Both configurations are offered. Fail safe is electrically locked, so it unlocks when power drops, which is what you want on an egress or stair-side opening tied to fire alarm release. Fail secure is electrically unlocked, staying locked on power loss, which suits exterior and storeroom-type openings where you do not want the door free when the system goes down. The solenoids are continuous duty, so fail safe units can sit energized all day without cooking.
4) What power supply do I need to run the ML453D electrified mortise lock?
It runs 12V or 24V AC/DC within plus or minus 10 percent, and voltage is field selectable with a plug-in bridge rectifier included. Draw is 700 mA at 12V or 350 mA at 24V, 8 watts total. Size your supply for that per door, and remember fail safe openings hold current continuously, so multiply the draw by the number of doors on the circuit.
5) Does the ML453D retract the deadbolt electrically, or only the latch?
The 453D is the entry with deadbolt function: the outside lever controls both the latchbolt and the deadbolt, so a valid access credential retracts both and the door opens in one motion. That is the difference from plain entry/office chassis that carry a latchbolt only.
6) What is the difference between the Command Access ML453D and the Schlage L9050BDC for an entrance/office door?
Both serve entrance/office openings, but the ML453D is an electrified chassis with 12V or 24V AC/DC continuous duty solenoids for remote keyless access and egress control, offered fail safe or fail secure. The Schlage L9050BDC is a mechanical single cylinder non-deadbolt function mortise entrance/office lock, Grade 1, heavy duty, for 1-3/4 inch doors, with a disposable SFIC cylinder. Choose the ML453D when the opening is tied into access control, the L9050BDC when it is key-operated only.
7) I need an electrified mortise lock for a storeroom opening, not entry with deadbolt. What should I use instead of the Command Access ML453D?
The ML453D is built for entry with deadbolt function, retracting both the latchbolt and the deadbolt under outside lever control. For a storeroom opening, the DynaLock EML-1 is an electrified mortise lock supplied in storeroom function. Both are electrified mortise chassis, so the difference is which function the opening calls for.
8) My access control spec calls for motorized latch retraction on a mortise lock. Does the ML453D meet that?
No. The ML453D uses continuous duty solenoids, rated for continuously on applications including fail safe unlock cycles, at 700 mA on 12V or 350 mA on 24V. If the drawing specifically calls for motorized latch retraction, the SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control for 1-3/4 inch doors.
9) Which switch option should I add to an electrified mortise lock for an access control system?
Three monitoring options are offered, and you pick one: REX request to exit signals the panel that someone turned the inside lever so the door does not alarm, LBM latchbolt monitor confirms the latch is actually thrown, and DPS door position tells you whether the door is closed. There is also a None option if the panel already gets its inputs from a separate door contact or the trim.
10) What are the alternatives to the ML453D if I need a motor-driven or storeroom-function electrified mortise lock?
A few other electrified mortise locksets cover different needs. The SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control for 1-3/4 inch doors, which is the choice when you want motor retraction rather than a solenoid. The SDC Selectric 7800 PRO is solenoid controlled with a vandal resistant clutch, also 1-3/4 inch. If the opening calls for storeroom function instead of entry with deadbolt, the DynaLock EML-1 is a storeroom function electrified mortise lock.
11) Can I use the Schlage L9050BDC as a drop-in replacement for a Command Access ML453D?
No. The two are not interchangeable functionally. The ML453D is an electrified chassis wired to 12V or 24V AC/DC with fail safe or fail secure solenoid operation and optional REX, LBM, or DPS switch monitoring for the access control system. The L9050BDC is a mechanical mortise entrance/office lock in a single cylinder non-deadbolt function. Swapping in the L9050BDC leaves the opening with no electrical control and no deadbolt.
12) Which electrified mortise locks carry a Grade 1 rating if my institutional spec requires it?
Among comparable electrified mortise locksets, the SDC 7600 Series is listed as Grade 1, as is the Schlage L9050BDC mortise entrance/office lock. The Command Access ML453D is specified as a heavy-duty commercial electrified mortise chassis on the Best 45H platform. If your submittal must show a Grade 1 line item, the SDC 7600 is the electrified option in that group.
13) I only have 24VDC available at the door. Which mortise lock fits that?
The Command Access ML453D is field-selectable for 12V or 24V AC/DC at plus or minus 10 percent with a plug-in bridge rectifier, drawing 350 mA on 24V, so it runs on a 24VDC supply. The SDC 7600 Series is a 24VDC control motorized latch retraction lockset. Both suit a 24V power supply; the ML453D also accepts 12V if the panel changes later.
14) Will the ML453D hold up on a high-traffic school or hospital entrance?
It is rated commercial heavy-duty, and the solenoids are continuous duty, built for openings that sit energized all day, including fail safe unlock cycles. Command Access lists it for commercial buildings, schools, healthcare entry points, government buildings, industrial sites, multi-tenant residential and retail.
15) I need to match the rest of my building's hardware. What finish does the ML453D come in?
One finish across the range: 626 satin chrome. That is the standard institutional finish, so it lines up with most existing commercial lever trim and exit hardware in a school or office building. If the building is standardized on a bronze or brass finish, this chassis will not match visually.
