Accentra NTM623-NR Grade 1 nexTouch Generation 3 Mortise Lock with Capacitive Touchscreen Keypad, No Deadbolt With Cylinder Override

Take control of facility access with the Accentra NTM623-NR Grade 1 nexTouch Generation 3 Mortise Lock. Engineered for high-traffic environments like multi-family properties, corporate offices, retail spaces, and common areas, this heavy-duty electronic mortise lock brings true standalone access management right to the door.

The NTM623-NR features a modern capacitive touchscreen keypad that wakes up instantly when touched, replacing traditional keys with unique multi-digit PIN codes. As a "No Deadbolt, With Cylinder Override" (Function 623) variant, this lock secures the door via a robust 3/4" deadlocking latchbolt—making it perfect for high-velocity entryways, management offices, or restrooms where automatic latching is required without manual deadbolt tracking. For total peace of mind, the lock is built with a mechanical key cylinder override, ensuring facility managers always have manual physical key access if required.

Designed for future-proof deployments, the lock functions flawlessly out of the box as a standalone unit supporting up to 100 localized user codes, but can be seamlessly upgraded down the road to network-based platforms (such as Data-on-Card or Zigbee/Z-Wave architectures) using plug-and-play modular radio cards.

Product Features

  • Grade 1 Certified Security: ANSI/BHMA A156.13 Series 1000 Grade 1 certified to withstand heavy commercial use, continuous abuse, and rigorous environments.

  • Capacitive Touchscreen Keypad: A sleek, durable glass touchscreen prevents physical button wear and avoids revealing code patterns to onlookers.

  • Automatic Guarded Deadlatching: Built without a manual deadbolt, the guarded latchbolt projects automatically when the door closes, preventing "shimming" and ensuring immediate security.

  • Mechanical Cylinder Override: Includes a conventional mechanical cylinder override prep, allowing emergency master key or secondary key entry.

  • Modular, Scalable Tech: Features an updateable design platform allowing standalone doors to be later converted into system-integrated openings.

  • Never-Locked-Out Power Protocols: Powered by 4 AA alkaline batteries with a low-battery alert indicator and an external 9V battery terminal jump-point at the bottom of the keypad to power the screen if the primary batteries die.

  • Three-Hour Fire Rated: UL/cUL listed for application on 3-hour fire doors, preserving crucial emergency compartment integrity.

Accentra AUR-NTM623-NR 626 – Frequently Asked Questions

1) Will the Accentra NTM623 nexTouch keypad mortise lock fit a 2-inch thick door?
Yes. The NTM623-NR is built for doors from 1-3/4 inches (44mm) up to 2-1/4 inches (57mm), so a 2 inch leaf is inside the range with no spacer kit or special order. That upper end matters on heavier commercial and multi-family entry doors where a standard 1-3/4 inch only lock will not close up against the trim.
2) Do I have to order the Accentra NTM623 handed, or is it field reversible?
Handing is not an order decision here. The nexTouch NTM623 uses a non-handed chassis that reverses in the field, so one part number covers left and right hand openings. For a property manager stocking spares across a building, that means one lock on the shelf instead of two.
3) Will the Accentra NTM623 latch into the mortise prep and strike already in my door?
It is cut for the standard commercial mortise prep with a 2-3/4 inch (70mm) backset and throws a 3/4 inch (19mm) deadlocking latchbolt, which is the normal ANSI mortise geometry, so an existing 2-3/4 inch backset mortise pocket and ANSI strike will take it. Check the lip projection on your old strike against the new latch, and remember the door needs to be within 1-3/4 to 2-1/4 inches thick.
4) What is the difference between the NTM623 and a nexTouch function with a deadbolt?
Function 623 is the no-deadbolt, cylinder-override configuration. Security comes entirely from the 3/4 inch guarded deadlatch that projects and deadlocks the moment the door closes, so nobody has to remember to throw anything behind them. Pick it for corridors, management offices, retail back-of-house and restrooms where the door has to secure itself on every swing. If you need a resident or occupant to positively lock and hold a room from inside, a deadbolt function is the one to spec instead.
5) Can I still get into the door with a key if the batteries die on the Accentra nexTouch NTM623?
Two ways in. The lock carries a mechanical cylinder override prep, so a conventional key cylinder gives you physical master or emergency key entry regardless of power. There is also an external 9-volt terminal at the bottom of the touchscreen: touch a 9V battery to the contacts and the keypad wakes long enough to enter a code. Primary power is 4 AA alkalines with a low-battery warning, and those are included.
6) Is the Accentra nexTouch NTM623 approved for a 3-hour fire door, and is it ADA compliant?
Fire rated, UL/cUL listed for 3-hour fire door openings, and ADA compliant to A117.1. It is also ANSI/BHMA A156.13 Series 1000 Grade 1, the heavy commercial mortise grade. That combination is what a facility or institutional spec normally calls for on a rated stair or corridor door.
7) What else could I use instead of the Accentra nexTouch if my doors are thinner than 1-3/4 inch?
The NTM623 will not work below 1-3/4 inches. Alarm Lock's Trilogy electronic mortise locks cover 1-5/8 to 1-7/8 inch doors, which includes the DL2700CR and DL3500CR in classroom function and the DL4500 deadbolt. For an aluminum storefront door with an Adams Rite deadlatch prep, the Alarm Lock DL1300NW Networx wireless keypad lock is the one built for that prep.
8) What is the closest equivalent to the Accentra NTM623-NR if I need a Grade 1 electronic mortise lock with a keypad and a mechanical key override?
The Schlage CO-100-MS-40-KP is a standalone electronic mortise lock with a keypad reader, heavy duty, Grade 1, for 1-3/4 inch doors, and the BEST 45HZ EZ Series is an electronic keypad mortise lock with key override function. The Accentra NTM623-NR is a Grade 1 nexTouch mortise lock with a capacitive touchscreen keypad and function 623, no deadbolt with cylinder override, and it takes a 2-3/4 inch backset on doors 1-3/4 inch to 2-1/4 inch. The Schlage CO-100 is catalogued as privacy function, so the keyed-override entry behavior of the 623 function is the point to confirm against your opening.
9) My doors are 1-5/8 inch thick. What electronic mortise lock fits instead of the Accentra NTM623-NR?
The Accentra NTM623-NR is built for doors 1-3/4 inch to 2-1/4 inch thick, so a 1-5/8 inch door falls below its range. The Alarm Lock Trilogy DL2700CR and DL3500CR are Grade 1 electronic mortise locks rated for doors 1-5/8 inch to 1-7/8 inch, as is the DL4500 Series electronic mortise deadbolt. The DL2700CR and DL3500CR are classroom function; the DL4500 is a deadbolt function with 2,000 user codes, against the 100 standalone codes the NTM623-NR holds.
10) I need a deadbolt on the door. What takes the place of the Accentra NTM623-NR, which has none?
The NTM623-NR is function 623, no deadbolt with cylinder override, securing the opening with a 3/4 inch deadlocking latchbolt only. For an electronic opening that throws a deadbolt, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with a privacy keypad, and the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a mobile-enabled deadbolt and a 125kHz proximity reader, 3 hour fire rated. Mechanically, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, the same backset the NTM623-NR uses.
11) Can I run the Accentra NTM623-NR on an access control panel, or do I need a wired lock?
The NTM623-NR is a standalone battery lock on 4 AA cells with a 9V external jump terminal, upgradeable later through plug-and-play radio cards. If the opening has to be controlled by a panel today, the BEST 45HW Series is a heavy duty wired electromechanical mortise lock running 12V or 24V, the Command Access ML190 Series is a heavy duty motorized storeroom mortise lock with field selectable EL/EU operation at 24VDC, and the Schlage L9092EU 03A is a heavy duty electric lock/unlock outside lever mortise lock with request to exit, 12/24VDC, for 1-3/4 inch doors.
12) For a classroom door, is the Accentra NTM623-NR the right function or should I pick something else?
The NTM623-NR is function 623, no deadbolt with cylinder override, with a guarded latchbolt that projects automatically when the door closes. It has no classroom lockdown function. For classroom openings, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with ANSI strike and steel escutcheon, and the TownSteel FME-4000 Series is an electronic intruder classroom mortise lockset with RFID.
13) I need a fire rated electronic mortise lock. Which options carry a fire rating alongside the Accentra NTM623-NR?
The NTM623-NR is UL/cUL listed for 3 hour fire doors and ANSI/BHMA A156.13 Grade 1. Among electronic mortise peers, the Schlage LEMD-GRW carries a 3 hour fire rating at Grade 1 in the ENGAGE Series, and the Schlage LEBMB-ADD is 3 hour fire rated at Grade 2 for 1-3/4 inch doors with a push button and LED. Mechanically, the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with a fire rating.
14) Will the Accentra NTM623-NR work on an aluminum storefront door with an Adams Rite deadlatch?
The NTM623-NR is a heavy duty mortise lock with sectional trim, a 2-3/4 inch backset, and a 3/4 inch deadlocking latchbolt for doors 1-3/4 inch to 2-1/4 inch thick, which is a hollow metal or wood door prep rather than a narrow aluminum stile. For storefront, the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock is built with a keypad for Adams Rite deadlatches, and the Dormakaba E-Plex 2066 is a wide stile electronic pushbutton keyless mortise lock. The Kaba Ilco BR Series is a glass door bottom rail lock.
15) What cylinder do I need to order with the Accentra NTM623 to key it into my master system?
The override takes a conventional mortise cylinder, supplied standard in the PARA keyway, and less-cylinder versions exist if your locksmith is keying it into an existing system. If the building is already mastered on a different keyway, order it less cylinder and drop in a conventional mortise cylinder cut to your system.
16) How many user codes does the Accentra nexTouch NTM623 hold, and can I connect it to an access control system later?
Standalone out of the box, holding up to 100 PIN codes programmed at the door, no software or wiring needed. The platform is modular: plug-in radio cards convert the same lock to Data-on-Card or Zigbee/Z-Wave network operation later without replacing the lock body or re-prepping the door. If you need well past 100 users at day one, an Alarm Lock Trilogy DL3500CR runs 300 codes and a DL4500 deadbolt runs 2,000.
17) What are the alternatives to an Accentra nexTouch keypad mortise lock for a standalone electronic opening?
Several Grade 1 standalone electronic mortise locks sit alongside it. The Schlage CO-100 keypad mortise lock is Grade 1 heavy duty in privacy function for 1-3/4 inch doors. Dormakaba's E-Plex E5086 is Grade 1 and adds card reading to the pushbutton, while the E-Plex 2066 is pushbutton keyless. If you want RFID credentials rather than PINs, the TownSteel FME-2000 is a Grade 1 heavy duty RFID mortise lockset in classroom function for 1-3/4 inch doors. The nexTouch is the one with a capacitive touchscreen and a 1-3/4 to 2-1/4 inch thickness range.
18) What should I use instead of the Accentra NTM623-NR if I want credentials on a card or phone rather than a PIN?
The NTM623-NR reads a capacitive touchscreen keypad and holds 100 user codes standalone, with modular radio cards to convert it to a networked opening later. If you want a card or phone credential at the door from the start, the TownSteel FME-2000 Series is a Grade 1 heavy duty classroom mortise lockset with RFID 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.
19) Is a mechanical Grade 1 mortise lockset a simpler alternative to the Accentra NTM623-NR for a storeroom or office door?
Yes, if you do not need PIN codes at the door. The NTM623-NR manages up to 100 user codes on a touchscreen and runs on batteries. A keyed mechanical equivalent for the same door type includes the Cal-Royal NM8080, a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, and the Cal-Royal NM8050, a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch. The Sargent 7925 is a heavy duty Grade 1 corridor/dormitory mortise lock with rose trim and a single cylinder deadbolt.
20) How does the Accentra NTM623-NR compare with the Dormakaba E-Plex pushbutton mortise locks?
Both are standalone keyless mortise locks. The NTM623-NR uses a capacitive touchscreen keypad and stores 100 codes, on 4 AA batteries with a 9V emergency jump contact. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock built for wide stile doors, the E-Plex E5086 is a Grade 1 back to back entry/egress pushbutton and card mortise lock, and the PowerPlex P2066 is a mortise lock in the PowerPlex 2000 Series. A mechanical pushbutton pad differs from a touchscreen in that the buttons themselves wear over time.
21) Which mortise products look like substitutes for the Accentra NTM623-NR but will not secure the door?
Several mortise items in the same size class do not latch a keyed opening. The Schlage PM010 and Falcon MA101 are Grade 1 passage mortise locks, non-keyed, which never lock. The Hager 3810E and 3810S are Grade 1 passage mortise locks on a 2-3/4 inch backset, the same backset the NTM623-NR uses, but passage function all the same. The Schlage L0170 is half dummy trim, Grade 1 non-keyed, and the Emtek 3102 Memphis and 3106 Manhattan mortise entrance locksets are dummy function. The Sargent 130KB is a mortise thumbturn, a trim piece rather than a lock.
22) Is there a lighter duty keypad mortise option than the Accentra NTM623-NR for a low traffic interior door?
The Codelocks CL2255 is an electronic tubular mortise latch in the CL2000 Series at medium duty, in a brushed steel finish. The Accentra NTM623-NR is a heavy mortise chassis certified to ANSI/BHMA A156.13 Series 1000 Grade 1 for heavy commercial traffic, with a mechanical cylinder override and a field reversible non-handed chassis. Pick by the traffic the opening actually sees and whether you need key override at that door.
23) For a behavioral health or anti-ligature opening, what replaces the Accentra NTM623-NR?
The NTM623-NR has a projecting touchscreen keypad and lever trim, which is not an anti-ligature profile. The TownSteel MRX-A-01 is a Grade 1 heavy duty ligature resistant arch trim mortise lockset in satin stainless steel, passage function for 1-3/4 inch doors, and the MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset in stainless steel. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant in satin stainless steel.
24) If I only need to replace the mortise lock body behind existing trim, is the Accentra NTM623-NR the wrong part?
Yes. The NTM623-NR is a complete electronic mortise lock with a capacitive touchscreen keypad, battery power and sectional trim, not a bare body. For a lock body alone, the BEST 45HCAC is a heavy duty mortise lock body with public entrance function and field reversible operation, the BEST 45HCAINL is a heavy duty mortise lockbody with intruder function, and 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, against the 2-3/4 inch backset the Accentra uses.
25) What finishes does the Accentra NTM623 nexTouch mortise lock come in?
Four: 605 bright brass, 613E dark oxidized satin bronze, 626 satin chrome, and BSP black suede powder coat. On a building where the other openings are already 626 satin chrome, that is the one that matches without a finish variance; BSP is the choice where the door hardware package is specified black.
26) Is a touchscreen keypad better than pushbuttons on a high-traffic entry door?
On a door seeing constant use, the capacitive glass face has no moving buttons to wear out and no worn keycaps to give away which digits are in the code. Mechanical pushbutton locks like the Dormakaba E-Plex 2066 or the Schlage LE Series push button trim are proven but do show wear patterns over time. If the opening is exterior and exposed, note that Alarm Lock's DL2700CR is the weatherproof-built option in the set.
27) Does the Accentra NTM623 use sectional trim or a full escutcheon?
Sectional trim on a heavy-duty mortise chassis. That matters if you are matching the look of adjacent openings: escutcheon-trim mortise locks such as the Hager 3810E or the Marks LA318GJ present a full plate instead, so mixing the two on the same corridor will read as a mismatch even when the finish is identical.
