BEST 45HW7DEU15H626 – Frequently Asked Questions

1) Will the BEST 45HW electrified mortise lock stay locked if the building loses power?
Yes. The 45HW in the EU (electrically unlocked) configuration is fail secure, so the outside lever stays locked when power drops and the door remains secured. Power is only applied to release it. If your application needs the opposite behavior, free egress side unlocked on power loss, that is the EL (electrically locked, fail safe) configuration, not this one. Fail secure is the usual choice where the opening has to stay secure during an outage and mechanical key override covers entry.
2) What backset does the BEST 45HW mortise lock use, and will it latch into my existing strike?
The 45HW is a 2-3/4 inch backset mortise lock with a 3/4 inch latchbolt throw. A standard commercial mortise prep in a hollow metal or wood door is cut at 2-3/4 inches, so the lever centers land where they already are on most existing openings. The 3/4 inch throw engages a standard ANSI mortise strike. If the door is currently carrying a cylindrical lock, the pocket has to be routed for a mortise case, that is not a drop-in swap.
3) Which BEST 45HW package option do I order if I need request-to-exit and door position monitoring?
Four package choices on the 45HW. None is the plain electrified lock with no monitoring. RQE adds request to exit signalling when the inside lever is turned. RQEDS adds request to exit plus door status. IDH is integrated door hardware with both RQE and door status. If your access control head end wants to know the door is actually closed as well as when someone exited from the inside, order RQEDS or IDH; RQE alone tells you nothing about door position.
4) Is there a mortise lock that does the same job as the BEST 45HW without running wire to the door?
Several standalone electronic mortise locks cover the opening without a wired power supply. The Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes and classroom function for doors 1-5/8 to 1-7/8 inches thick, and the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader on a 1-3/4 inch door. The BEST 45HW is a wired lock, not battery operated, and depends on 12 or 24 volt AC or DC power at the frame plus an access control head end. Standalone keypad locks trade that central control and real-time lock/unlock for a credential list held at the door.
5) Will a card reader mortise lock replace a wired BEST 45HW on an access controlled door?
Not on the same wiring scheme. The TownSteel FME-2000 is a Grade 1 mortise lockset with RFID technology, heavy duty, for 1-3/4 inch doors, and the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. Those read the credential at the door itself. The BEST 45HW takes its unlock signal over 12 or 24 volt wiring from the panel, with the reader mounted separately on the wall, and it is supplied with a temperature control module and connector as part of every order. Swapping to a reader-in-the-lock product moves the credential decision out of the panel and changes how the opening is commissioned.
6) Do I have to buy a temperature control module separately for a BEST W-series electrified lock?
No. Every W-series lock requires a Temperature Control Module, and the TCM plus its connector ship standard with each order. Nothing extra to specify or source. That is worth knowing on a bid: the module is a required part of the assembly, not an accessory line item.
7) Is the BEST 45HW electrified mortise lock approved for use in California and New York City?
Yes on both. It is UL listed under GYQS for electrically controlled single point locks and latches, carries California State Fire Marshal approval under section 13144.1 of the Health and Safety Code (CSFM listing 4136-1175:101), and is approved by the New York City Board of Standards and Appeals under calendar number 49-88-SA. Those three cover most institutional submittal requirements for an electrified opening.
8) Do I need to specify handing when ordering a BEST 45HW mortise lock?
The latchbolt on the 45HW reverses in the field without opening the lock case, so one lock covers either hand and you are not stuck if the door swings the other way than the drawing said. The lever and rose trim still install per the hand of the door, but the case itself does not have to be ordered handed.
9) What is the difference between a wired electrified mortise lock like the BEST 45HW and a standalone battery keypad mortise lock?
The 45HW is a hardwired, non battery lock that takes its command from your access control system, an individual switch, a switch lock, or a relay. There is no keypad and no onboard user database. If the opening has no wiring and you want codes managed at the door instead, a standalone unit is the other route: the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes and classroom function, and the Dormakaba E-Plex 2066 is a pushbutton keyless mortise lock. Wired gives you real time control and audit at the head end; standalone saves the wire pull.
10) What else could I use instead of a BEST 45HW if I need a fail secure electrified mortise lock with request to exit?
Two close alternatives from other brands. The Schlage L9092EU with 03A lever trim is a keyed outside electric lock/unlock mortise lock with request to exit, 12/24VDC, heavy duty, for 1-3/4 inch doors. The Command Access ML190 is a motorized mortise lock with field selectable EL/EU operation on 24VDC, heavy duty storeroom function, which is useful when you are not certain at order time whether the opening will end up fail safe or fail secure. The 45HW is fixed in the fail secure EU configuration.
11) What should I use instead of the BEST 45HW if the door does not need to be electrified at all?
For a keyed opening with no power at the frame, 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 for 1-3/4 inch doors. Both hold the door locked from the outside and are opened by key, with no wiring, power supply, or temperature control module involved. The BEST 45HW carries the electrified hardware because it is meant to be unlocked remotely through switches, relays, or an access control system; if that remote control is not part of the scope, a mechanical storeroom body does the same physical job.
12) Can I use a Schlage PM010 or a Falcon MA101 in place of a BEST 45HW electrified mortise lock?
No. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation. Passage function means the lever always retracts the latch from both sides, so there is nothing to secure or to release remotely. The BEST 45HW is keyed and electrically unlocked, so it holds the outside lever rigid until the access control system energizes it. A passage body fits the same mortise pocket but gives up the entire security function.
13) What is the difference between the BEST 45HW and a mortise deadbolt like the Sargent 4874?
The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, and the Kaba Ilco 185 series is a mortise deadbolt with no handing. Those are bolt-only bodies, thrown and retracted by key, with no lever and no latch. The BEST 45HW carries both a stainless steel deadbolt and a 3/4 inch throw reversible latchbolt in one case, shares the 2-3/4 inch backset, and adds the electrified control that releases the outside lever. A deadbolt alone will not let anyone through the door on an access control release.
14) Would a Baldwin 6310 mortise lock work as a substitute for the BEST 45HW?
It fits a different kind of door. The Baldwin 6310 is an entry/storeroom knob by knob mortise lock body on a 2-1/2 inch backset for doors 1-3/8 inch and over, and the 6301LS is a lever by lever entry/apartment body on the same 2-1/2 inch backset. The BEST 45HW uses a 2-3/4 inch backset, so the mortise pocket and cross bore locations are not the same, and it is a commercial electrified unit rather than a mechanical residential-style entry body. Substituting one for the other means re-prepping the door.
15) For a behavioral health or patient room, is the BEST 45HW the right electrified mortise lock?
Those rooms are usually specified with anti-ligature trim. The TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless ligature resistant arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant in satin stainless steel. The BEST 45HW uses a 15 lever with an H flat rose and is offered in 626AM satin chrome and 630AM satin stainless antimicrobial finishes for healthcare, which suits a controlled corridor or med room rather than a patient-side opening.
16) Is a Codelocks CL2255 an alternative to the BEST 45HW for a commercial door?
They are built to different duty levels. The Codelocks CL2255 is an electronic tubular mortise latch in brushed steel, rated medium duty. The BEST 45HW is a commercial unit with a cold rolled steel case, zinc dichromate plating, stainless steel bolt components, and a continuous duty electrical rating, UL listed for GYQS electrically-controlled single point locks with CSFM and New York City approvals. On a high traffic or code-reviewed opening those listings are what the specification is checking for.
17) Does the BEST 45HW electrified mortise lock come in an antimicrobial finish for a hospital?
Two orderable finishes, 626 satin chrome and 630 satin stainless steel, and BEST offers those in antimicrobial variants as 626AM and 630AM for healthcare openings. 630 satin stainless is the usual pick in patient care corridors and food service areas where the finish takes constant cleaning.
18) Can the BEST 45HW be keyed into an existing masterkey system?
It is a keyed mortise lock, so it accepts a cylinder for mechanical override and can be brought into a keying system. BEST locks conventionally take the small format interchangeable core, which is what makes rekeying a fleet of doors a core swap rather than a service call at each opening. Confirm the core format your building already runs before you commit the order.
19) Is the BEST 45HW mortise lock heavy enough for a high traffic commercial corridor?
Built for commercial duty: the case is cold rolled steel with zinc dichromate plating, and both the deadbolt and latchbolt are stainless steel. The latch runs oil impregnated for smooth throw over long cycle counts, and the electrical side is rated continuous duty rather than intermittent, which matters on an opening that sits energized all day. It is a commercial specification lock, not a residential one.
20) What trim comes on the BEST 45HW 15 lever version?
The 15 lever paired with the H rose, a 2-3/4 inch flat round rose. That is the trim across every orderable combination, in 626 satin chrome or 630 satin stainless. If you are matching a floor of doors that already run a flat rose, this profile lines up; an escutcheon plate opening is a different trim style and will leave the old plate footprint exposed.
21) I ordered a BEST 45HW and got sent a Falcon MESC600DT and a Schlage L0170 - are those the same thing?
They are not locks. The Falcon MESC600DT is dummy escutcheon lever trim for M9900 series exit devices with a fire rating, and the Schlage L0170 is half dummy trim, a Grade 1 mortise non-keyed lever lock for 1-3/4 inch doors. Dummy trim is a fixed pull with no latch behind it. The BEST 45HW is a complete electrified mortise lock body with a keyed cylinder, a 3/4 inch throw latchbolt, and a deadbolt. Dummy trim is what you order for the inactive leaf of a pair, not for the opening being controlled.
