ND44 - HOSPITAL PRIVACY LOCK

Push-button locking. Unlocked from outside by turning emergency turn-button. Turning inside lever or closing door releases button. Inside lever is always free for immediate egress.

 

Schlage ND SERIES OVERVIEW

The Schlage ND Series offers a full breadth of commercial lock options with a suited combination of mechanical, electrified and electronic options. This overview covers common characteristics for the mechanical and electrified lock information.

Beyond grade 1 performance is the hallmark of the mechanical and electrified locks. ND Series locks are tested to withstand 3,100 in-lb. of abusive lever torque - more than 2 1/2 times the Grade 1 standard requirement. Offset lever pull testing up to 1,600 lbs. assures you of the lock's superb resistance against pry bar attacks. More than strong, ND Series is built to last and shows nearly zero droop or wobble after 16 million cycles.

All ND Series locks including electronic and ligature-resistant trim use the common cylindrical ANSI 161 door preparation making them easily interchangeable. They are ideal for all new construction and retrofit applications.

 

ND Series Mechanical Lock

The ND mechanical lock, along with being Schlage’s best selling mechanical lock, is the foundation for both the wired electrified and NDE wireless electronic lock. Not only did Schlage invent the cylindrical lock, but we continue to make it better with capabilities such as:

  • Unparalleled strength - the lock prevents access even when subjected to torque loads up to 3,100 in-lbs (2.6x BHMA1), withstands pry bar attacks of 1,600 lbs (8x BHMA requirements1), and withstands 100 hammer blows (20x BHMA requirements1, 2)
  • Exceptional durability - cycle tested to over 16M cycles (16x BHMA requirements1) with near zero droop or wobble - without the use of set screws or O-rings
  • Improved feel - improved strength and durability are more than numbers, you can actually feel it in the lock
  • Improved installation - installation is even easier than before (and withoutany set screws or O-rings)

 

FEATURES & BENEFITS

Security

  • Significantly exceeds ANSI/BHMA Grade 1 requirements
  • No access with minimum 3,100 in-lb. abusive lever torque, the equivalent of over 690 lbs. applied to the end of a 4-1/2" lever, 2.6 times over the BHMA requirement*
  • No access with minimum 1,600 lbs. offset lever pull for protection against pry bar attacks, 8 times over the BHMA requirement*
  • 5 points of engagement provide nearly zero droop and wobble after 16 million cycles, 16 times over the BHMA requirement*, without the use of set screws or o-rings
  • High security locking when used with Primus XP UL 437 listed cylinders

Function availability and convenience

  • 24 mechanical/4 electrified functions (custom functions available)
  • Multiple key systems available: open, patented and restricted
  • Four electrified functions auto-detect 12/24V DC operation and, with maximum current draws of 0.4 amps and 0.1 amps holding current eliminate heated levers
  • Indicator roses for classroom applications
  • Three spring cage sets support all Schlage plus eight competitive cylinder formats

Aesthetics

  • Nine lever and four rose designs
  • Ten available finishes
  • Perfectly suited to Schlage ALX Series grade 2 locks

Schlage ND44S RHO 626 RH OS-OCC – Frequently Asked Questions

1) How does the Schlage ND44 hospital privacy lock get opened from the outside in an emergency?
The ND44 locks with a push button on the inside, and from the corridor side it opens by turning the emergency turn-button on the outside rose. No key, no tool. The button also releases when someone turns the inside lever or when the door closes, so it can't be left latched by accident. The inside lever is always free, so anyone in the room walks out in one motion regardless of what the button is doing. That combination is why this function goes on patient rooms, exam rooms and staff toilets where staff need to get in fast but egress can never be blocked.
2) What does the VACANT / OCCUPIED indicator on the Schlage ND44 show, and which side is it on?
The indicator sits on the outside rose and reads VACANT or OCCUPIED, driven by the push button. Someone in the corridor can tell whether the room is in use without knocking or trying the lever. That is the whole point of specifying an indicator version over a plain hospital privacy lock in a clinic, a single-occupancy restroom or a lactation room, where the traffic outside the door is constant and a wrong entry is a real problem.
3) Will a Schlage ND44 drop into the door prep I already have from another ND Series lock?
Yes. Every ND Series lock, including the electronic and ligature-resistant trims, uses the common cylindrical ANSI 161 door preparation, so an ND44 goes into an existing ND prep without redrilling. That makes it a straight function swap when a room changes use, say a plain privacy ND40 room becoming a treatment room that needs the indicator and the outside emergency release. The standard latch is a 2-3/4 inch backset spring latch with a square corner 1-1/8 x 2-1/4 inch face, so check that the existing latch bore matches that backset before ordering.
4) Do I have to specify a hand for the Schlage ND44 indicator lock?
The ND44 chassis itself is non-handed, but the indicator version is ordered left hand or right hand because the indicator window and lettering have to read correctly on the outside of the door. Determine the hand from the outside of the opening, standing on the corridor side, before ordering. If you are stocking spares for a floor with doors swinging both ways, you need both hands on the shelf, not one part that covers everything.
5) Should I use a cylindrical indicator lockset like the ND44 or an indicator deadbolt on a restroom door?
Two different jobs. The ND44 is a single cylindrical lever lock: latch, lever, locking and the VACANT/OCCUPIED indicator all in one ANSI 161 bore, and the inside lever always retracts the latch for egress. An indicator deadbolt, such as the Hager 3216 thumbturn by occupancy indicator with a 1 inch throw, or the Arrow E50 exit deadlock with vacant/occupied outside, is a second device added above a passage set, so the occupant has to throw the bolt and then also turn the lever to get out. For a single-occupancy public restroom where you want one motion in and one motion out, the cylindrical lock is the cleaner answer. Where the door already has a working passage set and you just need to add occupancy indication, the deadbolt route costs you less door work.
6) What is the closest Grade 1 equivalent to the Schlage ND44 hospital privacy indicator lock from another manufacturer?
The Corbin Russwin CLX3320 NVSL is the nearest peer. It is an extra heavy duty Grade 1 visual status lever lock with a privacy/bed/bath function in the CLX3300 Series, and it carries a fire rating. The Schlage ND44 is likewise a Grade 1 cylindrical lever lock with hospital privacy function and an exterior VACANT/OCCUPIED indicator. The functional difference to check before you swap: the ND44 is unlocked from outside by turning an emergency turn-button, which is what makes it a hospital privacy lock rather than a plain privacy lock. The Accentra AUYPL02 in the YPL Series is the other Grade 1 lever peer with a visual status indicator, listed with a privacy/bed/bath function. The Corbin Russwin lists a door thickness range of 1-3/4 inch to 2 inch, so confirm your door falls in it.
7) Is an indicator deadbolt like the Cal-Royal IND90-G2 or Hager 3216 a substitute for a Schlage ND44?
No, and this is the most common mis-order in the indicator category. The ND44 is a cylindrical lever lockset with a latch and lever trim, non-keyed, with hospital privacy function. The Cal-Royal IND90-G2 and the Hager 3216 are indicator deadbolts with a thumbturn x indicator function, and the Hager throws a 1 inch bolt. A deadbolt has no latch and no handle, so it does not operate the door; it is installed above a separate passage set. If the opening currently has a single bored lockset and you order a deadbolt, you get no latching and no lever. Order the deadbolt only when you are adding indicator status to an opening that already has a working passage or entry set.
8) What indicator lock should I use on a single-occupancy public restroom instead of a hospital privacy lockset?
The Falcon H2171 is built for that opening. It is a public restroom interconnected lock with an occupancy indicator and a single cylinder deadbolt, Grade 2, in the H2 Series, with a storeroom/public restroom function. An interconnected lock retracts the latch and the deadbolt together with one motion of the inside lever, which is how a single-user restroom meets egress with a thrown bolt. The Schlage ND44 is a non-keyed cylindrical hospital privacy lock, where push-button locking is released by turning the inside lever or closing the door, and outside entry is by emergency turn-button. Choose the ND44 for patient rooms and behavioral or care settings where staff need immediate outside release; choose the H2171 where a keyed deadbolt and restroom occupancy status are wanted.
9) Is the Schlage ND44 tough enough for a high traffic public restroom or a school?
Heavy duty commercial, and the numbers are well past the Grade 1 minimum. The lock holds against 3,100 in-lb of abusive lever torque, 2.6 times the BHMA requirement, and 1,600 lbs of offset lever pull, 8 times the requirement, which is the pry bar case. Cycle life is 16 million with near zero lever droop and no set screws or O-rings holding it together. On a restroom door that gets hung on and yanked all day, that is the difference between a lever that sags in a year and one that does not.
10) Which lever style and finish do I order to match the Schlage ND44 to the rest of my building?
Nine lever designs are offered: Athens, Boardwalk, Broadway, Latitude, Longitude, Omega, Rhodes, Sparta and Tubular. Finishes run to ten: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial and 643E aged bronze. If you already have ND or ALX locks on the other doors, order the same lever and finish code and the indicator door will not stand out. 626AM is the one to ask about for patient rooms and food service, and if the levers have to meet California Fire Code, stay with Rhodes, Sparta, Tubular, Omega, Longitude or Boardwalk, which have a 1/2 inch or less return to door.
11) Do I need a key or cylinder with the Schlage ND44 hospital privacy lock?
No cylinder, no key, nothing to key into your system. The ND44 is a non-keyed function. Outside access is by the emergency turn-button only, so there is no keyway to match to the building's master system and no cylinder to buy separately. If you need staff to open the room with a key instead of a turn-button, this is the wrong function and you should be looking at a keyed ND Series lock.
12) Can the Schlage ND44 be dogged or held unlocked, and can it lock someone in?
No, and that is deliberate. The push button releases the moment the inside lever is turned or the door is closed, so the room cannot be left in a locked state after the occupant leaves and no one can be locked in. The inside lever is always free for immediate egress, which is what keeps it legal on a patient room or a restroom under egress code. If you want a lock that stays locked until someone deliberately unlocks it, this is not the function.
13) Is there a lighter duty indicator option than the Schlage ND44 for a low-traffic door?
Yes, if the opening only needs occupancy status and not a Grade 1 lever lockset. The Falcon D271 is a Grade 2 medium duty deadbolt with an occupancy indicator and a thumbturn inside, in the D200 Series. The Cal-Royal IND84 is a Grade 3 indicator deadbolt with a thumbturn x indicator function. The Arrow E50 is a Grade 2 non-keyed exit deadlock with a VACANT/OCCUPIED indicator outside, fitting doors 1-3/8 inch to 1-3/4 inch. All three are deadbolts, so the door still needs its own latching hardware. The Schlage ND44 is Grade 1 heavy duty and carries both the latching and the indicator in one chassis.
14) Can an Emtek thumbturn privacy bolt be used in place of a Schlage ND44 on a commercial door?
They solve different problems. The Emtek 8383 Wilshire, 8483 Watford, 8583 Square, and 8683 Disk are thumbturn privacy bolts with double rosettes and an indicator, and each is specified for use with a brass passage set, so a separate passage handle set is required to latch the door. Their function is privacy/bed/bath. The Schlage ND44 is a commercial Grade 1 heavy duty cylindrical lever lock in zinc and steel that latches and indicates in one unit, and it meets hospital privacy function with an emergency turn-button for outside release. The Emtek bolts are the choice where a decorative thumbturn is being paired with an existing passage set; the ND44 is the choice where a single commercial-duty lockset must do the whole job.
15) For a healthcare facility standardizing on one indicator lock, which options carry Grade 1?
Three carry Grade 1: the Schlage ND44, the Accentra AUYPL02 in the YPL Series, and the Corbin Russwin CLX3320 NVSL in the CLX3300 Series. The Accentra and Corbin Russwin are both privacy/bed/bath function lever locks with visual status indicators. The Schlage ND44 is hospital privacy function, where the outside is released by an emergency turn-button and the inside lever is always free for immediate egress, and it is non-handed with a 13-248 spring latch on a 2-3/4 inch backset. Where a facility wants indicator status on a door that already has its lockset, the Cal-Royal IND90-G2 indicator deadbolt with an ADA thumbturn is also Grade 1. Match the function first, then the grade.
16) I need an indicator on a 1-3/8 inch door - will a Schlage ND44 peer fit?
Among the indicator products, the Arrow E50 exit deadlock and the Accentra D292 cylindrical deadbolt both list a door thickness range of 1-3/8 inch to 1-3/4 inch, so both cover a 1-3/8 inch door. The Arrow E50 is a Grade 2 non-keyed unit with a VACANT/OCCUPIED indicator outside; the Accentra D292 is a Grade 2 deadbolt in the D Series with a thumbturn x indicator function. The Corbin Russwin CLX3320 NVSL lever lock starts at 1-3/4 inch, so it does not cover a thinner door. Note that both fitting options are deadbolts, so a 1-3/8 inch door still needs its own latching set alongside.
17) Which indicator lock options are fire rated for a labeled opening?
The Corbin Russwin CLX3320 NVSL Grade 1 visual status lever lock and the Hager 3216 Grade 2 thumbturn x occupancy indicator deadbolt are both listed as fire rated. The Schlage ND44 is UL/cUL listed for 3-hour A label single fire doors up to 4 feet by 10 feet, and for 8 foot by 8 foot pair doors at 3 hours or 8 foot by 10 foot pairs at 90 minutes with the 3/4 inch latch option, and it meets ADA requirements. On a labeled opening, confirm the leaf size against those limits before choosing between the lever lock and a deadbolt-plus-passage-set approach.
18) What is the Schlage ND44 made of and will it hold up in a wet or wiped-down room?
Chassis and trim are zinc and steel. For a room getting wiped with disinfectant daily, the finish choice matters more than the substrate: 626AM satin chrome antimicrobial is the one specified for patient rooms and food handling areas, and 626 satin chrome is the standard commercial default that hides handling. Bright brass 605 and bright chrome 625 will show every fingerprint in that setting.
19) Is the Cal-Royal IND84 the same thing as the IND90-G2?
No. Both are Cal-Royal indicator deadbolts with a thumbturn x indicator function, but they sit at different performance levels: the IND84 is Grade 3, and the IND90-G2 is Grade 1 and comes with an ADA thumbturn. If a facility spec calls out an accessible thumbturn or a Grade 1 requirement, the IND84 will not satisfy it. Neither is a replacement for a Schlage ND44, which is a Grade 1 cylindrical lever lockset rather than a deadbolt.
