DynaLock EML-2 Series, EML Series Electrified Mortise Lock Institutional Function

Yes. The EML Series is built to retrofit the Schlage L9000 Series, so it drops into the same mortise pocket and door prep you already have. That is the usual path when a facility standardized on L9000 locks and now needs an opening put on access control without cutting a new door.

Institutional function means both levers are locked at the same time, so neither side gives free entry or free egress by lever. A key retracts the latchbolt from either side. When power is applied, both levers will retract the latchbolt. That is the function used on detention, psychiatric, secure storage, and utility openings where you do not want anyone passing without a key or a released credential. If you need free egress from the inside, this is the wrong function.

Both modes are field-selectable on the EML Series, so the lock itself is not a one-way decision at the order form. Fail-safe (EL) unlocks on power loss, which is what you want on stair re-entry and any opening the fire alarm has to release. Fail-secure (EU) stays locked on power loss, which is what you want on a storeroom, IT room, or narcotics closet that must not open when the building drops power. Lock mode is also an order option, so pick the mode the opening runs in day to day and know the other is available in the field.

No. Handing is field-reversible on the EML Series, so one lock covers left and right hand openings. If you are buying several for a floor and are not certain of every swing, that removes the risk of a wrong-hand delivery.

The EML runs on 12-24 VAC or VDC input. In institutional function the draw is 700mA at 12 VDC or 350mA at 24 VDC. Size the supply off those figures and multiply by the number of locks on the circuit, plus the transfer hinge or door loop losses. Running the system at 24 volts halves the current per lock, which is why most multi-door jobs are specified at 24.

Three switch options are orderable on the EML: a door position switch, a latchbolt monitor, and request to exit. Door position tells the panel whether the door is closed, the latchbolt monitor tells it whether the door is actually secured (a door can be closed and not latched), and REX signals a legitimate lever pull so the alarm does not trip. On an institutional opening most integrators take latchbolt monitor plus door position, since knowing the leaf is shut is not the same as knowing it is locked. If a lock is already installed without REX, there is a request to exit monitor switch field upgrade kit for mortise locks that adds it without replacing the lockset.

No, that is a storeroom function opening, not institutional. Institutional function locks both levers at once, so the inside lever will not let someone out without a key or applied power. For locked outside lever with the inside lever always free, look at a storeroom function lock: the SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset, the Command Access LPM190-M-EU-CH is a 24V motorized mortise lock with electric unlock and optional REX in storeroom function, and the Command Access ML1080LB is a heavy-duty storeroom function mortise chassis. Getting this wrong on an egress path is a code problem, not just a comfort one.

The Schlage L9050BDC is a mechanical Grade 1 mortise entrance/office lock for 1-3/4 inch doors, with a disposable SFIC and no deadbolt. It has no electrical control at all: it is key and lever only. The EML is the electrified path on the same door prep, since it is built to retrofit the Schlage L9000 Series and takes 12-24 VAC/VDC from an access control panel. So if a few openings on a floor need to go on card access and the rest stay mechanical, you can swap in the EML at those doors and leave the L Series everywhere else with the prep unchanged.

The closest peer for an institutional-function electrified mortise application is the Command Access ML04EU electrified mortise lock chassis, which Command Access lists with the Asylum/Institution/Utility function in its ML05 Series and rates heavy-duty. Both are electrified mortise locks built for the institutional function, where the levers are controlled electrically and the latchbolt is retracted by key. The DynaLock EML Series difference is that fail-safe (EL) and fail-secure (EU) locking mode is field-selectable on the same lock and handing is field-reversible, while the Command Access part is catalogued as the EU variant. If you are stocking for a facility where the door's power-fail behavior may change, the field-selectable EML is the one that covers both modes.

No. The Schlage L9050BDC is a mortise entrance/office lock, single cylinder non-deadbolt function with a disposable SFIC, in the Schlage L Series, Grade 1 heavy duty for 1-3/4 inch doors. It is a mechanical lock - there is no electrical control of the levers. The DynaLock EML is an electrified mortise lock operating on 12/24 VDC with electrically locked (fail-safe) or electrically unlocked (fail-secure) operation. The connection between them runs the other way: the EML Series is designed to retrofit the Schlage L9000 Series, so an opening currently carrying an L9050BDC takes an EML when that door needs to come onto access control.

The DynaLock EML Series is ordered with the monitoring built in: door position switch, latchbolt monitor, and request to exit are each yes or no options on the lock, and a request to exit monitor switch field upgrade kit for mortise is available if the signal is added later. Among the alternatives, the Command Access LPM190-M-EU-CH is a 24V motorized mortise lock listing optional REX. If the panel needs door position and latch status as well as REX from a single mortise lock, specify those switches on the EML at the time of order rather than adding hardware to the frame.

Check the lock before the panel. The DynaLock EML Series accepts 12/24 VDC and draws 700mA at 12 VDC or 350mA at 24 VDC, so it lands on either supply. Several of the alternatives are 24V parts: the Command Access LPM110ECH is listed with 24VDC operation, the LPM190-M-EU-CH is a 24V motorized mortise lock, and the SDC 7600 Series uses 24VDC control. On a facility standardized at 12 volts, the dual-voltage EML avoids adding a supply at the door.

Yes. A request to exit monitor switch field upgrade kit for mortise locks is available as an option, so an EML already hung in an opening can have REX added rather than pulled and replaced. Useful when a building gets tied into a new access control head end after the doors were done.

Four plated finishes are offered: 605 bright brass (US3), 613 dark bronze (US10B), 625 bright chrome (US26), and 626 satin chrome (US26D). 626 satin chrome is the standard commercial finish and the one most institutional buildings are already standardized on, so if you are matching existing lever trim in a school or hospital corridor that is almost always the match. For a brass or bronze scheme, 605 and 613 cover it.

No. Standard bent lever trim is included with the EML Series, so the lockset arrives complete for the door. What you still have to source is the cylinder and keying, since institutional function relies on key retraction from either side, plus the power transfer (electric hinge or door loop) to get 12-24 volts into the leaf.

The EML is a solenoid-type electrified mortise lock: power controls whether the levers are coupled to the latch, and the latch itself is retracted by the lever or the key. A motorized latch retraction lockset instead pulls the latchbolt back electrically from the panel, so the door can be held free-swinging or released remotely without anyone touching the lever. The SDC 7600 Series is a Grade 1 motorized latch retraction mortise lockset with 24VDC control, and Command Access offers the LPM110ECH heavy-duty electrified latch retraction mortise chassis at 24VDC. Pick latch retraction when you need the panel to physically open the latch, for example an automatic operator or a lobby door on a schedule. Pick the EML when you need controlled lever access with key override.

Commercial. The EML Series is ANSI/BHMA Grade 1, which is the highest of the three BHMA grades and the one specified for institutional and heavy commercial openings. That matters on a corridor or classroom door in a school or hospital, where a Grade 2 lock will not hold up to the cycle count.

Storeroom function is a different lock, not a setting on an institutional one. On the institutional function the outside and inside levers are both controlled electrically together and the latchbolt is retracted by key from either side, which is what a facility uses when the inside must be held under control as well. For a straight storeroom opening, the Command Access ML1080LB is a heavy-duty storeroom function mortise lock chassis in the ML1 Series, and the Command Access LPM190-M-EU-CH is listed with storeroom function in the LPM19X Series with electric unlock and optional REX. Order the institutional EML only when the inside lever needs to be secured electrically too.

For an opening where the levers take deliberate abuse, the SDC Selectric 7800 PRO Series is a solenoid controlled mortise lock with a vandal resistant clutch, listed for 1-3/4 inch doors, and the clutch is the feature that absorbs force applied to the trim. The DynaLock EML Series is also solenoid controlled and comes with standard bent lever trim, and it is the one to specify when the requirement is a UL Listed Grade 1 lock for a labeled fire door rated up to 3 hours with field-selectable fail-safe or fail-secure mode. Match the choice to whether trim abuse or fire-door listing and mode flexibility is driving the spec.

That depends on what is already in the door. The Command Access ML04EU and ML1080LB are catalogued as mortise lock chassis, as is the LPM110ECH electrified latch retraction mortise lock chassis with 24VDC operation in the LPM18X Series - a chassis goes into an existing mortise pocket where the trim and cylinder are being reused. The DynaLock EML Series is a complete lockset that includes standard bent lever trim and is designed to retrofit the Schlage L9000 Series prep. If the existing Schlage trim is staying on the door, a chassis is the shorter path; if the whole lock is being replaced, the EML arrives with its trim.
