Command Access ML45DEU-CH-24V-REX – Frequently Asked Questions

1) What happens to the Command Access ML45DEU-CH when power drops?
It stays locked. The ML45DEU-CH is a fail secure unit, so losing 24V power leaves the outside lever locked. Key override from the outside still works, and the inside lever is always free for egress, so a power loss never traps anyone. If your opening needs the outside lever to unlock on power loss (a stair re-entry door, for example), fail secure is the wrong choice.
2) Does the ML45DEU-CH include a request to exit signal, or do I need a separate REX device?
REX is built into the lock body, so you do not need a separate motion sensor or REX bar at the opening. Turning the inside lever generates the exit signal back to the access control panel, which is what you want for shunting a door contact alarm. Latchbolt Monitor and Door Position Switch are offered as additional monitoring options if the panel also needs latch and door status.
3) Is the ML45DEU-CH a complete lockset, or just the lock body?
Lock body only. The ML45DEU-CH is the electrified mortise lock chassis. Levers, roses or escutcheons, and the cylinder are ordered separately, so budget the trim and the keying into the job. If you want a lockset that arrives with trim on it, the Schlage L9050BDC mortise entrance/office lock is sold as a complete Grade 1 unit, though it is a mechanical entrance function rather than an electrified storeroom.
4) I need an electrified storeroom mortise lock but my system runs 12V. Is this the right part?
No. The ML45DEU-CH is a 24V unit, and running it on 12V will not pull the solenoid reliably. Specify the 12V version of the ML45 series instead, or size a 24V supply for the opening. The DynaLock EML Series is another electrified mortise lock in storeroom function if you are shopping the function rather than the voltage.
5) What is the closest equivalent to the Command Access ML45DEU-CH electrified mortise lock body from another manufacturer?
The DynaLock EML-1 is the nearest straight equivalent. Both are electrified mortise locks in storeroom function: the ML45DEU-CH is an electrified mortise lock body with storeroom function, and the DynaLock EML-1 is an EML Series electrified mortise lock also listed in storeroom function. The difference to confirm before swapping is the electrical side, since the ML45DEU-CH is specified at 24V and fail secure with a Request to Exit configuration, and the DynaLock should be ordered to match the voltage and fail mode your access control panel is wired for.
6) I need a Grade 1 electrified mortise lock for a 1-3/4 inch door - what should I look at instead of the Command Access ML45DEU-CH?
The SDC 7600 Series is the one to price. It is a Grade 1 motorized latch retraction mortise lockset with 24VDC control, rated for a 1-3/4 inch door thickness. It runs on the same 24V class of control power as the Command Access ML45DEU-CH, which is a 24V fail secure electrified mortise lock body, but the SDC 7600 retracts the latch with a motor rather than a solenoid-released lever, so the panel output and timing requirements differ.
7) Can I use a Schlage L9050BDC in place of the Command Access ML45DEU-CH?
No - they are not interchangeable functionally. The Schlage L9050BDC is a mechanical Grade 1 mortise entrance/office lock, single cylinder non-deadbolt, heavy duty, for a 1-3/4 inch door. It has no electrification, so it cannot be released from an access control panel. The Command Access ML45DEU-CH is an electronic 24V fail secure lock body with a Request to Exit output, which is what ties the opening into a card reader or intercom system. Use the L9050BDC only where the door is keyed and not controlled electrically.
8) What does storeroom function mean on this electrified mortise lock?
Outside lever is electronically controlled and stays locked until the access control system energizes the solenoid; a key in the outside cylinder always overrides. The inside lever is free at all times, so egress is never dependent on power or on the panel. That combination is why storeroom is the usual pick for card-reader doors on healthcare, school, and multi-tenant openings.
9) Is the ML45DEU-CH solenoid rated to stay energized all day?
Yes. It uses continuous duty solenoids intended for continuously on applications, which matters if your access control scheme energizes the lock for long unlock windows or scheduled open periods rather than short momentary releases. Intermittent duty hardware run that way overheats; this one is built for it, at 8 watts steady.
10) How does the Command Access ML45 compare to an SDC motorized latch retraction mortise lock?
Two different mechanisms. The ML45DEU-CH is solenoid controlled and unlocks the outside lever. The SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control, meaning it pulls the latchbolt back, which is what you use when the door has to swing free under an automatic operator. The SDC 7800 PRO is solenoid controlled like the Command Access unit but adds a vandal resistant clutch on the lever. Both SDC series are listed for 1-3/4 inch doors.
11) Can the fail secure setting on the ML45DEU-CH be changed in the field?
The fail mode is field configurable on this unit, so the installer sets it at the opening rather than ordering a separate part number. It ships and is catalogued as fail secure, which is the mode you want on stockrooms, IT closets, and tenant suite doors where the door must stay locked through a power interruption.
12) The opening gets abused - is there an electrified mortise lock built for vandalism instead of the Command Access ML45DEU-CH?
Look at the SDC Selectric 7800 PRO Series, a solenoid controlled mortise lock with a vandal resistant clutch, fitted to 1-3/4 inch doors. Like the Command Access ML45DEU-CH it is solenoid controlled rather than motor driven, so the panel wiring concept is similar; the clutch is what lets the outside lever spin free under force rather than transmit the abuse into the lock case. The ML45DEU-CH is specified as heavy-duty commercial in storeroom function without a clutched lever.
13) My access control panel only puts out 24VDC - which mortise locks match that besides the Command Access ML45DEU-CH?
The Command Access ML45DEU-CH is specified at 24V, and among the comparable electrified mortise locks the SDC 7600 Series is the one that states 24VDC control directly in its description. Note the difference in what the 24V does: on the ML45DEU-CH it drives a solenoid in a fail secure lock body with Request to Exit, while on the SDC 7600 it drives motorized latch retraction, which typically draws an inrush your supply and panel output need to be sized for.
14) What is the difference between the Command Access ML45DEU-CH and the SDC 7800 for a storeroom door?
Both are solenoid controlled mortise locks. The Command Access ML45DEU-CH is configured for storeroom function at 24V, fail secure, with Request to Exit built in, so the outside lever stays electrically locked with key override while the inside lever always releases. The SDC Selectric 7800 PRO Series is a solenoid controlled mortise lock whose distinguishing feature is a vandal resistant clutch, and it is dimensioned for 1-3/4 inch doors. Choose on whether the opening needs the REX signal back to the panel or the clutched outside lever.
15) Is this lock heavy enough for a high traffic commercial opening?
It is built as heavy duty commercial hardware, not residential grade, and the application list runs to hospitals, schools, government buildings, and multi-tenant residential. For a facility standardizing across many openings, the ML45 series covers the electrified storeroom doors; pair it with the monitoring options (latchbolt monitor, door position switch) where the panel needs to see door and latch status.
