BEST 45HWCADEU626 – Frequently Asked Questions

1) Does the BEST 45HW electrified mortise lock stay locked or unlocked when the power fails?
It stays locked. The 45HW EU function is electrically unlocked, which means power is what releases the outside lever, so a power loss leaves the opening secure. That is the right choice for storerooms, IT rooms, and exterior perimeter doors where you never want the door to free up in an outage. If your opening is on an egress or fire alarm interface that has to release on power loss, you need the EL (electrically locked, fail safe) version of the same series instead.
2) Will a BEST 45HW mortise lock drop into my existing mortise pocket and strike?
The 45HW uses a 2-3/4 inch backset, which is the standard commercial mortise backset, so it lines up with a standard ANSI mortise prep. The latchbolt throws 3/4 inch and the deadbolt throws 1 inch, so an existing ANSI strike with a deadbolt cutout will take it. What is different from a mechanical swap is the door: an electrified lock needs a wire path, so the door and frame need an electric hinge or power transfer and a raceway to the mortise pocket. If the existing door has no power path, that is the work, not the lock body.
3) Does the BEST 45HW electrified mortise lock come with a cylinder or core?
No core is included. The lock is prepped for BEST small format interchangeable core (SFIC) and ships less core, so you order the core separately and key it to whatever system the building already runs. For a property manager or locksmith standardizing a facility, that is the point: the same SFIC core family drops into these locks and into the rest of the BEST hardware on site. It is a single cylinder keyed function, so the key operates from one side.
4) What do I have to specify when ordering a BEST 45HW fail secure mortise lock?
Three things get chosen on the order. Finish, which is 626 Satin Chrome. Lock type, which is the electronically unlocked fail secure function. And the package option: None for the plain lock, RQE if you need a request-to-exit signal back to the access control panel, or IDH for integrated door hardware. Take RQE if the panel has to know the inside lever was turned, for example to shunt an alarm or log a legitimate egress. Add the SFIC core to the order separately.
5) Is the BEST 45HW electrified mortise lock UL listed and approved for use in California?
Yes on both. The 45HW is UL listed under GYQS for electrically-controlled single point locks or latches, and it is approved by the California State Fire Marshal under section 13144.1 of the California Health and Safety Code, CSFM listing number 4136-1175:101. It also carries a New York City Board of Standards and Appeals approval under calendar number 49-88-SA. Those are the three listings a spec writer or an institutional buyer usually has to show on a submittal.
6) 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 has no keypad, no card reader, and no battery, it takes 12 or 24 volt power from a panel and unlocks when the access control system tells it to. All credential reading, scheduling, and audit lives in that panel. A standalone lock puts the reader and the decision at the door instead: the Schlage CO-100 is a keypad standalone mortise lock, the TownSteel FME-2000 is an RFID mortise lockset, and the Dormakaba E-Plex 2066 is a pushbutton keyless mortise lock. Choose the 45HW when the building already has an access control head end and you want the door on it. Choose a standalone when there is no panel and running wire to the door is not worth it.
7) What is a comparable wired electrified mortise lock to the BEST 45HW from another brand?
Two close ones. The Schlage L9092EU with 03A lever is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, for 1-3/4 inch doors. The Command Access ML190 is a motorized mortise lock with field selectable EL/EU operation on 24VDC, storeroom function, heavy duty. The Command Access unit is the one to look at if you have not settled fail safe versus fail secure yet, since it is switchable in the field; the BEST 45HW EU and the Schlage EU are ordered as fail secure. The BEST is the pick when the site is already on BEST SFIC keying, since it is prepped for that core.
8) What is the closest equivalent to a BEST 45HW fail secure electrified mortise lock from another manufacturer?
The Schlage L9092EU in the 03A trim configuration is the nearest match. It is a heavy duty mortise lock with an electric lock/unlock outside lever, keyed outside, request to exit, and 12/24VDC operation, which lines up with the BEST 45HW EU function running 12V or 24V AC/DC and with the RQE request to exit package option. The Schlage carries a 1-3/4 inch door thickness. The BEST 45HW uses a 2-3/4 inch backset and an SFIC prep less core cylinder, so a facility already keyed to BEST small format interchangeable cores keeps that keying with the 45HW.
9) Which electrified mortise lock can be set to either fail safe or fail secure in the field?
The Command Access ML190 series motorized mortise lock is field selectable between EL and EU operation and runs on 24VDC, in a heavy duty storeroom function. The BEST 45HW is ordered as a specific function instead: EU functions are electrically unlocked fail secure and EL functions are electrically locked fail safe, so the failure mode is fixed at the time of order. If the door's fail mode may change after installation, the field selectable ML190 covers both states from one part number.
10) Is a keypad mortise lock a substitute for a fail secure electrified mortise lock on an access controlled door?
They are not interchangeable. Credential-at-the-door locks such as the Dormakaba E-Plex E5086 Grade 1 electronic pushbutton/card mortise lock, the Schlage CO-100 standalone electronic mortise lock in privacy function, and the TownSteel FME-2000 Grade 1 classroom mortise lockset with RFID make the access decision at the lock itself. The BEST 45HW carries no reader; it is electrically unlocked in the EU fail secure function by a signal from an access control panel at 12V or 24V AC/DC. If the design calls for a central panel, card readers, and door position monitoring, the 45HW is the lock that takes that signal; if the door is meant to run on its own credential list, a standalone is the right family.
11) Do I need the RQE option on an electrified mortise lock, or is a separate request-to-exit device fine?
RQE built into the 45HW lock body senses the inside lever and reports it to the panel, so free egress is always mechanical and the panel still gets a clean signal. Order it if the door is alarmed or monitored and you want the egress logged or the door contact shunted without adding a ceiling motion sensor or a push-to-exit button. If the access control side only needs to unlock the outside lever remotely and nothing is monitoring the door, the plain package (None) is enough.
12) Is there an electrified mortise lock finish suitable for a hospital or clinic?
The 45HW is offered with antimicrobial finishes, 626AM Satin Chrome and 630AM Satin Stainless Steel, which is what healthcare facilities specify on patient corridor and clinical room doors. The lock is a commercial-duty unit with a cold rolled steel case, zinc dichromate plating, and stainless steel deadbolt and latchbolt.
13) Do I have to order a BEST 45HW electrified mortise lock left hand or right hand?
The latchbolt is reversible and it reverses without opening the case, so one lock covers either handing and you set it in the field. That matters for a service truck or a facility parts crib: you stock one unit instead of two. The latchbolt is oil impregnated.
14) I only need a keyed storeroom mortise lock with no electronics. What should I buy instead of the 45HW?
Skip the electrification and the power supply entirely. The Accentra 8805FL is a Grade 1 storeroom mortise lock with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, listed for 1-3/4 inch doors. Both give you the same always-locked outside lever behavior as an EU lock sitting unpowered, without a panel, wire, or transfer hinge. Only go electrified when the door genuinely has to be released remotely or put on a credential system.
15) If the opening does not need remote release, what mechanical mortise lock covers the same door?
For a keyed opening with no access control tie-in, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors. The BEST 45HW is the electrified path: it is keyed, single cylinder, and adds 12V or 24V electrical unlocking through an access control system, which none of those three do.
16) Will a mortise deadbolt work in place of an electrified mortise lock?
A deadbolt-only body does not latch the door, so it does not replace a latching lockset. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, the Kaba Ilco 185 series is a no-handing mortise deadbolt, and 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. The BEST 45HW carries both a 1 inch stainless steel deadbolt throw and a 3/4 inch latchbolt throw on a 2-3/4 inch backset, so the door latches on close and the deadbolt is part of the same case.
17) What is the difference between the BEST 45HW and a mobile or RFID mortise lock for a multi-tenant building?
The Schlage LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with a push button and LED covering privacy, office and apartment functions on 1-3/4 inch doors with a 3 hour fire rating, and the Dormakaba Saffire LX-I-M002 is a BHMA Grade 2 electronic RFID mortise lockset with BLE mobile access. Both put the credential at the door for tenant-issued phone or card access. The BEST 45HW is wired to the building's access control system, is UL listed for GYQS electrically-controlled singlepoint locks and CSFM approved, and takes an SFIC less core cylinder so mechanical master keying stays with the building's own core system.
18) For a healthcare corridor, what mortise lock options are there besides the BEST 45HW?
The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel, ligature resistant and ADA compliant, and the TownSteel MRX-A-01 and MRX-L-01 are Grade 1 heavy duty ligature resistant passage mortise locksets for 1-3/4 inch doors in arch trim and lever trim respectively. Those are passage function with no credential control. The BEST 45HW is the controlled-access option for the same environment, offered in 626AM satin chrome and 630AM satin stainless steel antimicrobial finishes.
19) Is the Temperature Control Module a separate purchase on a BEST W-series mortise lock?
No. All W-series locks require a TCM, and both the module and its connector ship standard with every 45HW order. Nothing extra to add to the requisition, and no reason to pull a TCM off another door.
20) Where can I get the wiring diagram and installation instructions for the BEST 45HW mortise lock?
BEST publishes 45H/47H installation instructions and a 40H Series heavy duty mortise lock catalog, both linked in the product documentation on the 45HW. Pull the installation sheet before you cut the door: it carries the mortise pocket dimensions and the wiring diagram you need to land the 12 or 24 volt feed and the TCM correctly.
21) What is a simpler mortise lock for a door that only needs to latch, with no keying and no power?
For a non-keyed opening the Schlage PM010 is a Grade 1 passage latch mortise lock for 1-3/4 inch doors, the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock that is field reversible and fire rated, and the Hager 3810S is a 3800 series Grade 1 passage mortise lock with rose on a 2-3/4 inch backset for doors 1-3/4 to 2-1/2 inches. All three share the mortise pocket approach without wiring or a cylinder. The BEST 45HW is keyed and electronic and needs a 12V or 24V supply at the door.
22) Is a mortise thumbturn or dummy trim the same part as an electrified mortise lock?
No. The Sargent 130KB and 130W are standard duty mortise thumbturns, the 130W with a round backplate, and the Schlage L0170 is a Grade 1 non-keyed half dummy lever trim for 1-3/4 inch doors. Those are trim and turn pieces that mount to a lock, not lock bodies that latch a door. The BEST 45HW is a complete mortise lock case with a 3/4 inch latchbolt, a 1 inch deadbolt, and 12V or 24V electrical unlocking.
23) What mortise lock handles a dormitory or corridor opening with a deadbolt if I do not need electrification?
The Sargent 7925 is a heavy duty Grade 1 dormitory exit function mortise lock in the 7900 series with rose trim and a single cylinder deadbolt. The BEST 45HW is also single cylinder keyed with a 1 inch deadbolt throw on a 2-3/4 inch backset, but its release comes from the access control system in the electrically unlocked fail secure function rather than from the door hardware alone.
24) Can a tubular or narrow stile electronic mortise latch replace a heavy commercial electrified mortise lock?
They serve different doors. The Codelocks CL2255 is a medium duty electronic tubular mortise latch in the CL2000 series, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock built for wide stile. The BEST 45HW is a commercial lock with a cold rolled steel case, zinc dichromate plating, and a stainless steel deadbolt and latchbolt on a 2-3/4 inch backset, wired for 12V or 24V access control release, so it is not a drop-in for a narrow stile or medium duty opening and those are not drop-ins for its prep.
