BEST 45HW7DEU3J630 – Frequently Asked Questions

1) What happens to the BEST 45HW electrified mortise lock when the power goes out?
It stays locked. The 45HW EU configuration is electrically unlocked, which means power is what retracts the outside lever control, so a power loss leaves the opening secure. That makes it the wrong choice for a door that has to free up on a fire alarm or power drop. For that behavior you want an EL (electrically locked, fail safe) function instead, which the 45HW family also offers.
2) Do I have to order a Temperature Control Module separately for a BEST W-series mortise lock?
No. Every W-series BEST lock requires a TCM to run, and the TCM plus its connector ship standard with each order of the 45HW. Nothing extra to add to the purchase order for that piece.
3) Will the BEST 45HW mortise lock fit a 1-3/4 inch door, and what about thicker doors?
Standard build is for 1-3/4 inch doors, which is the usual commercial thickness. Thick door options are available up to 5 inches, so an oversized or clad door can be accommodated, but that has to be specified at time of order rather than adjusted in the field.
4) Will the BEST 45HW mortise lock work with my existing ANSI mortise pocket and strike?
It uses a 2-3/4 inch backset, the standard commercial mortise backset, with a 1 inch stainless steel deadbolt throw and a 3/4 inch latchbolt throw. If the pocket you are replacing into is a standard 2-3/4 inch backset mortise prep with a strike cut for a 1 inch deadbolt, the bolts will engage. What you do have to add is a wire path, since this is an electrified lock and the existing prep on a mechanical lock will not have an electric hinge or door loop.
5) Is the BEST 45HW electrified mortise lock approved for use in California and New York?
Yes on both counts. It is UL listed under GYQS for electrically controlled single point locks and latches, approved by the California State Fire Marshal under section 13144.1 of the Health and Safety Code (CSFM listing No. 4136-1175:101), and accepted by the New York City Board of Standards and Appeals under calendar number 49-88-SA. Check the CSFM listing for the allowable values and conditions of use that apply to your opening.
6) What is the closest equivalent to the BEST 45HW electrified mortise lock from another manufacturer?
The Schlage L9092EU electric lock/unlock mortise lock with the 03A lever trim is the nearest peer. Like the BEST 45HW fail secure unit, it is a heavy duty mortise lock built for electrified access control and runs on 12/24VDC, and it is keyed from the outside. The Schlage is specified as a corridor function for 1-3/4 inch doors and adds a request-to-exit (RX) switch, which the 45HW description does not cover. The BEST 45HW uses a 2-3/4 inch backset with a 1 inch deadbolt throw and ships with the Temperature Control Module required by all W-series locks.
7) I need to switch between fail safe and fail secure in the field. Is there a mortise lock that does both?
The Command Access ML190 series motorized mortise lock is field selectable between EL (fail safe) and EU (fail secure) operation and runs on 24VDC, catalogued as a storeroom function heavy-duty lock. The BEST 45HW electrified mortise lock is ordered in a fixed configuration - the EU version is electrically unlocked, fail secure - so the operating mode is chosen at the time of order rather than set at the door.
8) We do not have power or wiring at the door. What mortise lock can we use instead of the BEST 45HW?
The BEST 45HW needs a wired power supply - 12 volts AC/DC at 0.60 amps or 24 volts AC/DC at 0.45 amps - so it is not an option on an unwired opening. Standalone keypad mortise locks avoid that: the Alarm Lock DL3500CR Trilogy is a Grade 1 classroom-function mortise lock with 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 Dormakaba PowerPlex P2066 is another keypad mortise option in the 2000 series.
9) Can I use a credential reader mortise lock instead of the wired BEST 45HW for card access?
Yes, if you want the credential read at the door rather than at a separate reader wired back to a panel. The TownSteel FME-2000 is a Grade 1 mortise lockset with RFID technology in classroom function for 1-3/4 inch doors, the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2, and the Schlage LEMD-GRW is a Grade 1 ENGAGE wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The BEST 45HW takes no credential itself - it is an electrically unlocked lock body that a separate access control system releases at 12 or 24 volts.
10) Our doors are thicker than 1-3/4 inches. Which electronic mortise locks will fit?
The BEST 45HW is standard for 1-3/4 inch doors with thick door options available up to 5 inch thickness, which is the widest range among the electrified mortise options. The Alarm Lock Trilogy DL2700CR and DL3500CR are both limited to 1-5/8 to 1-7/8 inch doors, and the Schlage CO-100 standalone keypad mortise lock and the TownSteel FME-4000 electronic classroom mortise lock are specified for 1-3/4 inch doors.
11) Does handing matter when ordering a BEST 45HW mortise lock?
The latchbolt is oil impregnated and reverses without opening the case, so the latch side can be flipped on site for either hand. The escutcheon trim and lever orientation still need to match the opening, so confirm the door swing when you order.
12) What is the difference between an electrified mortise lock like the BEST 45HW and a standalone electronic mortise lock with a keypad?
The 45HW is a wired lock with no credential reader of its own. It has to be tied to a power supply and an access control panel, which unlocks it remotely at 12 or 24 volts. A standalone unit such as the Alarm Lock DL3500CR Trilogy carries its own keypad and stores user codes at the door, and the Dormakaba E-Plex 2066 works the same way with pushbutton entry. Choose the 45HW when the opening is part of a managed access control system and you want central control and monitoring; choose a standalone when you need controlled entry on a door with no wiring to it.
13) What is a comparable fail secure electrified mortise lock if the BEST 45HW does not suit my opening?
Two close alternatives. The Schlage L9092EU with 03A trim is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation, on 1-3/4 inch doors. The Command Access ML190 Series is a motorized mortise lock with field selectable EL or EU operation at 24VDC, which is worth a look if you are not certain yet whether the opening needs fail safe or fail secure, since it can be set either way rather than committed at order time like the 45HW EU.
14) Is the BEST 45HW mortise lock keyed, and can I put it on my existing key system?
Yes, it is a keyed mortise lock. BEST mortise hardware is built around the removable interchangeable core, so an existing BEST keyway core drops in and the door joins the master key system already in the building. Specify the core and keying with the order.
15) If the opening does not need remote release, what is a simpler mortise lock than the BEST 45HW?
Where a mechanical key lock will do, a straight Grade 1 mortise lockset is the simpler route. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 series, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors. None of these carry the 45HW's electrified fail secure operation or its Temperature Control Module, so they cannot be released from an access control panel.
16) We need an electrified mortise lock with the same 2-3/4 inch backset. What else matches?
The BEST 45HW uses a 2-3/4 inch backset. Among mortise peers on that same backset, the Hager 3800 series covers 3810E passage with escutcheon, 3810S passage with rose, 3840S privacy and 3850E office with lever and escutcheon, and the Sargent 4874 is a double cylinder mortise deadbolt at 2-3/4 inch backset. Those are mechanical, so if the 2-3/4 inch prep must also carry remote release, the electrified match is the Schlage L9092EU mortise lock at 12/24VDC for 1-3/4 inch doors.
17) What should I order instead of the BEST 45HW for an aluminum storefront or narrow stile door?
The 45HW is a wide-body electrified mortise lock body for 1-3/4 inch doors and is not a narrow stile product. For aluminum openings, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is built with a keypad for Adams Rite deadlatches, and the Kaba Ilco BR series is a glass door bottom rail lock. The Dormakaba E-Plex 2066 electronic pushbutton keyless mortise lock is specified as wide stile.
18) Is the Schlage LEBMB-ADD a drop-in alternative to the BEST 45HW electrified mortise lock?
They solve different problems. 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 it carries its own credential handling at the door. The BEST 45HW is a wired fail secure lock body that a central access control system releases at 12 or 24 volts AC/DC, UL listed for GYQS electrically-controlled singlepoint locks with California State Fire Marshal approval.
19) What is the difference between the BEST 45HW electrified mortise lock and the Accentra nexTouch NTM623-NR?
The Accentra NTM623-NR is a Grade 1 nexTouch Generation 3 mortise lock with a capacitive touchscreen keypad, no deadbolt, and cylinder override - users enter a code at the lock. The BEST 45HW has no keypad; it is keyed, electronically operated from a wired supply at 12 or 24 volts, and includes a stainless steel deadbolt with a 1 inch throw alongside a 3/4 inch latchbolt.
20) What trim and finish does the BEST 45HW fail secure lock come with?
It comes with the J wrought escutcheon with a 3 lever design, in 630 satin stainless steel. Satin stainless is the common spec in healthcare, education, and government work, so it will sit alongside most existing commercial trim without standing out.
21) How durable is the BEST 45HW lock case for a high traffic commercial door?
The case is 0.095 cold rolled steel with zinc dichromate plating for corrosion resistance, and the deadbolt and latchbolt are both solid stainless steel. It is rated for continuous duty electrical operation, which is what you want on a door cycling all day under an access control system rather than an intermittent duty unit.
22) Is the Sargent 130KB or 130W a substitute for the BEST 45HW mortise lock?
No. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 series and the 130W is a mortise thumbturn with a round backplate in the 7800 series - both are trim pieces that retract a bolt from the inside, not lock bodies. The BEST 45HW is a complete electrified mortise lock with a 2-3/4 inch backset, a 1 inch stainless deadbolt throw and a 3/4 inch latchbolt throw, supplied with a J wrought escutcheon trim.
