Command Access ML170EUCH-24V – Frequently Asked Questions

1) Will the Command Access ML170EUCH work with the Schlage L Series levers and escutcheons already on my doors?
Yes. The ML170EUCH is a chassis-only electrified mortise lock built to retrofit any Schlage L Series compatible trim, so you keep the existing levers, roses and escutcheons and swap only the lock body inside the mortise pocket. Because it is sold as a chassis, plan on reusing your trim and cylinder rather than expecting a complete lockset in the box.
2) What happens to the ML170EUCH when the power drops out?
It locks. The ML170EUCH is the fail secure (EU) configuration, so the outside lever is unlocked electronically only while power is applied. Cut the power and the outside lever goes back to locked. Inside egress is free at all times, which is what keeps it usable on a classroom or corridor door. If you need the opposite behavior (unlocked on power loss for an egress path), you want the EL fail safe version instead.
3) What voltage and current does this electrified mortise lock need from my access control power supply?
24VAC or 24VDC, drawing 350 mA at 8 watts. A plug-in bridge rectifier is supplied with the lock, so either an AC or a DC source works. Size the supply for the full 350 mA per lock and note the solenoid is continuous duty, so it can sit energized indefinitely on unlock-cycle or continuously-on schedules without cooking.
4) Is the Schlage L9050BDC an equivalent to the Command Access ML170EUCH?
No. The Schlage L9050BDC is a mechanical Grade 1 heavy duty mortise entrance/office lock, single cylinder non-deadbolt function with a disposable SFIC, for 1-3/4 inch doors. The Command Access ML170EUCH is an electrified classroom chassis that requires 24V power to release the outside lever. The connection between them is trim: the ML170EUCH chassis retrofits Schlage L series compatible trim, so an existing L series opening can be converted to electrified access control while keeping the lever trim.
5) What is the difference between the Command Access ML170EUCH and the DynaLock EML-1 electrified mortise lock?
Both are electrified mortise locks, but they are built for different door functions. The Command Access ML170EUCH is a classroom function chassis with fail secure operation, meaning the outside lever is released electronically when power is applied while inside egress stays free. The DynaLock EML-1 in the EML series is a storeroom function electrified mortise lock, where the outside lever is normally fixed and entry is by key or electronic release. Choose by which function the opening calls for on the door schedule.
6) If I need latch retraction rather than lever control on an electrified mortise lock, what should I use instead of the ML170EUCH?
The Command Access ML170EUCH controls the outside lever electronically - the latch itself is not withdrawn electrically. If the application requires the latch to be pulled back under power, the SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control for doors 1-3/4 inch thick. Both operate on 24V, so a 24V supply sized for the chosen unit serves either approach.
7) Do I have to order a handing for the ML170EUCH, or can I reverse it on the job?
Handing is field reversible on this chassis, so one part number covers left and right hand openings and you can reconfigure later if a door swing changes. The EL/EU electrical configuration is the choice that matters on the order form: ML170EUCH is the EU fail secure build.
8) Is this a true classroom function lock, and where does it fit in a school?
Yes, the ML170EUCH is a classroom function chassis, electrified for remote control of the outside lever. The outside lever is released electronically when power is applied while the inside lever always retracts the latch for free egress, so it suits classroom doors, healthcare patient and treatment rooms, government and corporate interior openings, and multi-tenant residential access points tied into a credential reader or lockdown system.
9) Is the ML170EUCH heavy enough for a high traffic commercial door?
It is a Grade 1 heavy-duty commercial chassis, not a light-duty or residential lock, and the solenoid is a continuous duty type rather than an intermittent one. That combination is what lets it sit in a school corridor or hospital wing where the door cycles all day and the lock may be held energized for long stretches.
10) I need a whole electrified mortise lockset, not just a chassis. What else could I buy?
The ML170EUCH is a chassis for existing Schlage L Series trim. If you are starting from bare doors, the SDC Selectric 7800 PRO Series is a solenoid controlled mortise lock with a vandal resistant clutch, and the SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control, both listed for 1-3/4 inch doors. The DynaLock EML Series covers electrified mortise in storeroom function if classroom operation is not what you need.
11) Can I standardize a whole building on this lock if some doors need to unlock on power loss?
Not on one part number. The ML170EUCH is the fail secure EU build only, which stays locked outside without power. Doors that must release on a fire alarm or power failure need the fail safe EL configuration of the same ML1 chassis. You can still standardize on the ML1 series and the same 24V supply across the building, specifying EU or EL per opening.
12) What electrified mortise lock offers a vandal resistant lever instead of the ML170EUCH?
The SDC Selectric 7800 PRO Series is a solenoid controlled mortise lock with a vandal resistant clutch, built for 1-3/4 inch doors. The Command Access ML170EUCH is also solenoid driven, using continuous duty solenoids for continuously on applications, and is supplied as a chassis for Schlage L series compatible trim. Pick the 7800 PRO where abusive lever torque is the concern and the ML170EUCH where you are retrofitting existing L series trim.
13) For a classroom door that must stay locked when power fails, is the ML170EUCH the right choice or do I need a different lock?
The Command Access ML170EUCH is the fail secure configuration - with power removed the outside lever stays locked, which is the usual requirement for classroom security. Among comparable mortise locks, the DynaLock EML-1 is a storeroom function unit, keeping the outside lever fixed as its normal state, and the mechanical Schlage L9050BDC entrance/office lock has no electrical release at all. The ML170EUCH is field reversible for handing and offered in EL/EU configurations if the project later calls for fail safe behavior.
