BEST 45HWCADEL626 – Frequently Asked Questions

1) Will the BEST 45HW electrified mortise lock stay locked or unlock when the power drops?
It locks. The 45HW in the EL (electrically locked) configuration is fail safe, meaning it is locked while energized and releases when power is removed. If you need the opposite behavior, a door that stays secure on a power loss, you want an EU function instead, which is electrically unlocked and fail secure. Get this decision right before ordering because it is not a field-changeable setting on this lock.
2) Will a BEST 45HW mortise lock fit a 1-3/4 inch door with a 2-3/4 inch backset prep?
Yes. The 45HW uses a 2-3/4 inch backset and is built for standard 1-3/4 inch thick commercial doors. If the existing prep on your opening is a 2-3/8 inch backset, which is common on residential and light interior doors, this lock will not drop in. Measure from the door edge to the center of the knob or lever hole to confirm which one you have.
3) Will the BEST 45HW latch into the strike and deadbolt keeper already in my frame?
The 45HW throws a 3/4 inch latchbolt and a 1 inch deadbolt, both stainless steel. That is the standard ANSI mortise lock throw pair, so an existing ANSI strike cut for a mortise lock with a deadbolt pocket will normally take it. If your current frame only has a latch strike with no deadbolt pocket, you will need to add that cutout or change the strike, since this is a single cylinder lock with a working deadbolt.
4) Does the BEST 45HW electrified mortise lock come with a core, or do I have to order one?
It ships prepped for a small format interchangeable core, less core. You supply and key the SFIC yourself, which is the whole point on a BEST system, since it lets you key the opening into a master system you already run and pull the core later without taking the lock apart. Budget for a 6 or 7 pin SFIC in your keyway on top of the lock.
5) Is the BEST 45HW electrified mortise lock approved for use on a fire or life safety opening?
It is UL listed under GYQS for electrically controlled single point locks and latches, and it carries California State Fire Marshal approval under section 13144.1 of the California Health and Safety Code, CSFM listing number 4136-1175:101. It is also accepted by the New York City Board of Standards and Appeals under calendar number 49-88-SA. Those three cover most of what an AHJ in a hospital, school, or municipal building will ask you to produce.
6) What is the closest equivalent to the BEST 45HW electrified mortise lock if I need field-selectable fail safe or fail secure instead of fail safe only?
The Command Access ML190 series motorized mortise lock is the closest heavy-duty peer with that capability - it is listed with field selectable EL/EU operation and 24VDC power, so one part number covers both electrically locked and electrically unlocked behavior and the choice is made at install. The BEST 45HW ships in the fail safe (electrically locked) configuration with 24V AC/DC operation at 0.45 amps, so the EL/EU decision is made at the time of order rather than in the field. Both are mortise-prep locks intended for commercial openings, so the door prep conversation is the same; the difference is where the function gets set.
7) How does the Schlage L9092EU compare to the BEST 45HW for an access-controlled corridor door?
The Schlage 03A electric lock/unlock outside lever mortise lock is a keyed-outside corridor function unit with request to exit (RX) signalling and 12/24VDC operation, fitted to 1-3/4 inch doors, heavy duty. The BEST 45HW runs on 24V AC/DC at 0.45 amps in fail safe (electrically locked) form and is prepped for a small format interchangeable core less core, with a 2-3/4 inch backset. The practical split: the Schlage carries the RX switch for door position and egress reporting back to the panel, while the BEST 45HW is specified around the SFIC keying program and accepts either AC or DC input. Pick on whether the panel needs an RX contact from the lock itself and on which core family the building is already keyed to.
8) If there is no way to run power to the door, what mortise lock should be used instead of the BEST 45HW?
A standalone electronic mortise lock is the substitute when wiring the frame is not practical. The Alarm Lock DL3500CR Trilogy is a Grade 1 classroom-function electronic mortise lock holding 300 user codes for 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in privacy function for 1-3/4 inch doors. The BEST 45HW is not battery operated - it is a wired unit requiring 24V AC/DC at 0.45 amps and a Temperature Control Module, which is what makes remote lock and unlock from an access control panel possible. Standalone units trade that central control for credential management at the door.
9) What is the difference between the BEST 45HW and a credential-reading mortise lock like the TownSteel FME-2000 or Schlage LEMD?
The BEST 45HW has no reader in it. It is a wired electrified mortise lock, fail safe at 24V AC/DC and 0.45 amps, that takes its lock and unlock command from a separate switch, relay, or access control system. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID technology built in for 1-3/4 inch doors, and the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. Those carry the credential reader at the door; the 45HW expects the reader and decision to live in the system it is wired to.
10) Do I need a temperature control module with a BEST 45HW wired mortise lock?
Yes, and it is included. Every W-series wired lock requires a TCM, and BEST supplies the TCM and its connector standard with each order, so there is nothing extra to specify on the purchase order. The module holds the coil operation stable across temperature swings, which matters on exterior and unconditioned openings.
11) Do I have to specify handing when ordering a BEST 45HW mortise lock?
The latchbolt is reversible in the field and flips without opening the case, so a change of hand on site does not mean a new lock. The faceplate is stainless and self-adjusts to the door bevel as you install it. Handing still matters for the trim you hang on it, so confirm the lever or knob side before you order the trim package.
12) Can I control a BEST 45HW mortise lock from an access control panel or a remote switch?
That is what it is built for. The 45HW takes its lock and unlock command from a dry contact or relay output, so it drops onto an access control system, an automatic control system, an individual switch, or a switch lock at a desk. It has no reader, keypad, or credential handling of its own, so the panel makes every decision and the lock just follows the 24V output.
13) What is the difference between a wired electrified mortise lock like the BEST 45HW and a standalone electronic mortise lock?
The 45HW is a wired lock. It needs 24V run to the door through a hinge transfer and a panel or switch to command it, and it gives you central control, real time lock and unlock, and one place to cut access. A standalone unit like the TownSteel FME-2000 Series or the Alarm Lock DL3500CR carries its own keypad or RFID reader and needs no wiring, which is cheaper to install but means programming each door individually. Pick the wired lock when the opening is already on an access control system or has to unlock on a fire alarm or a lobby release.
14) Which mortise lock replaces the BEST 45HW when the opening does not need electric control at all?
A mechanical Grade 1 mortise lockset covers the same door prep without any power run. The Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, which keeps a small format core keying program intact - the BEST 45HW is supplied with an SFIC prep less core. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 series with an Arcadia lever, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 series for 1-3/4 inch doors. All three hold the door mechanically only; the 45HW is the electrified option at 24V AC/DC.
15) Is a Trilogy DL4500 electronic mortise deadbolt an alternative to the BEST 45HW electrified mortise lock?
They solve different openings. The Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad for 1-5/8 to 1-7/8 inch doors - deadbolt function, meaning it throws a bolt and has no latching lockset behavior. The BEST 45HW is a keyed single cylinder electrified mortise lock with a 1 inch deadbolt throw and a 3/4 inch latchbolt throw, and it is controlled remotely through switches, relays, or an access control system at 24V AC/DC. If the requirement is central lock and unlock of a latched door from a panel, the deadbolt is not a substitute.
16) Can a Baldwin 6310 mortise lock body be used in place of the BEST 45HW?
No - the backsets do not match. The Baldwin 6310 entry/storeroom mortise lock body is a 2-1/2 inch backset unit for doors 1-3/8 inch and over, and the lever by lever 6310190RRLS is the same 2-1/2 inch backset in a right hand reverse configuration. The BEST 45HW uses a 2-3/4 inch backset, so the mortise pocket and cross bore locations differ and one will not drop into the other's prep. The Baldwin units are also mechanical, while the 45HW is an electrified lock operating at 24V AC/DC.
17) For a classroom opening, is the BEST 45HW or a classroom-function mortise lock the right specification?
It depends on whether the door is on the access control system. A classroom function mortise lock like the Cal-Royal NM8070, a Grade 1 classroom lockset with auxiliary deadlatch for 1-3/4 inch doors, or the Marks USA LA318GJ Grade 1 classroom security indicator mortise lockset with ANSI strike and steel escutcheon, secures the door by key at the door. The BEST 45HW in fail safe form unlocks when power is removed, which is how a building-wide lockdown or release is driven from a central panel at 24V AC/DC. Facilities that want the door to release on a power loss, or to be commanded from a console, specify the electrified unit; those that want the teacher to control the door at the opening specify the mechanical classroom function.
18) Is a Sargent 130KB mortise thumbturn or a 4874 mortise deadbolt a substitute for the BEST 45HW?
Neither one is. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 series and the 130W is a standard duty thumbturn with round backplate in the 7800 series - those are trim pieces that turn a lock, not lock bodies. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset in the 4870 series, which throws a bolt but has no latch and no electrical control. The BEST 45HW is a complete electrified mortise lock body with a 1 inch deadbolt throw, a 3/4 inch latchbolt throw, and 24V AC/DC operation. Ordering a thumbturn or a deadbolt against a 45HW line item leaves the opening without the electrified lock it was specified for.
19) For a dormitory or corridor door that needs an exit function and a deadbolt, what mortise lock is used instead of the BEST 45HW?
The Sargent 7925 is the mechanical answer - a Grade 1 heavy duty dormitory exit function mortise lock in the 7900 series with rose trim and a single cylinder deadbolt. Exit function means the inside always retracts both bolts on a single motion for egress, controlled at the door. The BEST 45HW is a single cylinder keyed electrified lock whose locked state is held by 24V AC/DC power and released when power drops, since it is the fail safe configuration. Specify the 7925 when the deadbolt is thrown by the occupant, and the 45HW when the corridor side must be commanded from an access control system.
20) What electronic mortise lock should be used instead of the BEST 45HW on an anti-ligature or behavioral health opening?
The TownSteel MRX series covers that opening mechanically - the MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel for 1-3/4 inch doors, and the MRX-A-01 is the passage function version with satin stainless ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel. The BEST 45HW is specified for its electrical control - 24V AC/DC fail safe operation tied to an access control system - and carries standard lever or knob trim rather than ligature resistant trim. On a room where the trim profile is the governing requirement, the MRX or 5PDN is the correct call.
21) I need to match the 626 satin chrome hardware already on my other doors. Does the BEST 45HW come in that finish?
Satin chrome, BHMA 626, is the finish this electrified mortise lock is built in, so it will sit alongside existing 626 levers, closers, and exit devices without a visual mismatch. The Schlage L9092EU electrified mortise lock is also carried in 626 if you are standardizing a building on that finish across brands.
22) Is the BEST 45HW mortise lock heavy duty enough for a school or hospital corridor?
The case is cold rolled steel with zinc dichromate plating, and both the deadbolt and the latchbolt are stainless steel, rated for continuous duty on the electrical side. It is a commercial specification lock, not a light duty or residential one, and BEST builds it to the same mechanical standard as their non electrified mortise locks. That is the construction you want on high traffic institutional corridors.
23) Does the Dormakaba PowerPlex P2066 do the same job as the BEST 45HW without running wire?
The Dormakaba PowerPlex P2066 series is a mortise lock in the PowerPlex 2000 family, and the E-Plex 2066 is an electronic pushbutton keyless mortise lock in the E-Plex 2000 series built for wide stile applications. Both put the credential and the power at the door. The BEST 45HW is a wired unit - it is not battery operated and requires 24V AC/DC at 0.45 amps plus the Temperature Control Module supplied with each order. The 45HW is the choice when the lock must answer to an access control system or relay; the Dormakaba units are the choice when the opening is standalone.
24) What is the simplest mortise lock to use on a door that does not need to lock at all, where the BEST 45HW would be overkill?
A passage mortise lock. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, the Hager 3810S is a Grade 1 passage mortise lock with rose on a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock, fire rated and field reversible. Any of these uses a mortise pocket without electrical rough-in or a keyed cylinder. The BEST 45HW is a keyed, single cylinder electrified lock with an SFIC prep, so it carries both the key system and the wiring that a passage opening does not need. Note the Hager 3810S shares the 2-3/4 inch backset with the 45HW.
