Schlage B660P 626 OS-OCC IS-LOC – Frequently Asked Questions

1) What backset does the Schlage B660 deadbolt need bored in the door?
2-3/4 inches fixed on the standard build, which is the deeper of the two common bored backsets. Schlage fixes it deliberately, since a non-adjustable backset gives the lock less to tamper with, though an adjustable version is offered. If your doors are already bored at 2-3/8 inches, you need the adjustable latch (12-296) rather than the fixed one.
2) What does the OS-OCC/IS-LOC indicator on a Schlage B660 actually show on each side of the door?
Two indicators, one per side, reading different things. The outside window shows occupancy so someone in the corridor knows the room is in use without trying the handle. The inside window shows the lock state so the occupant can confirm the bolt is actually thrown. It is a single cylinder deadbolt, thumbturn inside and key cylinder outside, so throwing the turn is what changes both readings.
3) What has to be specified when ordering a Schlage B660 besides the finish?
Three things. Cylinder format, choosing between the 6-pin conventional C keyway cylinder, an FSIC housing less core, or an SFIC prep less core. Keying, either keyed different (the standard) or keyed alike when a run of locks should share one key. And keyway, C or S123. The less-core options ship without a core, so an SFIC or FSIC order needs cores supplied from your own system. Conventional cylinder builds come with two cut nickel silver keys per lock.
4) Is the Schlage B660 deadbolt still Grade 1 if I order it with interchangeable cores?
No, and this is the trap on the order form. The A156.5 Grade 1 certification applies with the conventional cylinder. Specify FSIC and the assembly certifies Grade 2; specify SFIC and it certifies Grade 3. If your spec sheet calls for Grade 1 hardware, the conventional cylinder is the only build that meets it, even though the bolt and case are the same across all three.
5) Is there a Grade 2 indicator deadbolt that works on a 1-3/8 inch door, since the Schlage B660 starts at a thicker door?
The Schlage B660 is built for commercial doors and its conventional and FSIC cylinder versions cover 1-5/8 inch to 2 inch, with SFIC covering 1-3/4 inch to 2 inch. For a 1-3/8 inch leaf, the Accentra D292 is a Grade 2 cylindrical indicator deadbolt with thumbturn, rated for doors 1-3/8 inch to 1-3/4 inch, and the Arrow E50 is a Grade 2 exit deadlock with a Vacant/Occupied indicator outside covering the same 1-3/8 inch to 1-3/4 inch range. The Arrow E50 is non-keyed, so choose the Accentra D292 if the outside still needs a key.
6) What is the difference between a Schlage B660 indicator deadbolt and the Falcon D271?
Both are indicator deadbolts, but they lock differently. The Schlage B660 is a Grade 1 heavy duty keyed deadbolt, cylinder outside and thumbturn inside, so an authorized key gets in from the corridor. The Falcon D271 is a Grade 2 medium duty deadbolt with an occupancy indicator and a one-sided function with the thumbturn inside, meaning there is no key override from outside. On a single-occupancy restroom or a lactation room where staff must be able to get in during an emergency, the keyed B660 is the one that answers that; where the room only needs to signal occupied, the D271 covers it with a simpler part.
7) What is the closest Grade 1 alternative to a Schlage B660 indicator deadbolt if the opening needs a lever rather than a bolt?
The Schlage B660 is a Grade 1 keyed single cylinder deadbolt with a cylinder outside and thumbturn inside, carrying occupancy indicators on both faces. When the opening calls for a latching lever instead of a deadbolt, the Corbin Russwin CLX3320 NVSL is a Grade 1 privacy/bed/bath visual status lever lock from the CLX3300 Series, fire rated, for doors 1-3/4 inch to 2 inch thick. The B660 secures with a bolt and a key outside; the CLX3320 latches and locks by privacy button with the status window in the lever trim, so it suits a restroom or exam room where nobody carries a key.
8) Can an Emtek 8383 privacy bolt be used in place of a Schlage B660 indicator deadbolt?
No. The Emtek 8383 Wilshire is a thumbturn privacy bolt on double rosettes with an indicator, intended to be installed alongside a brass passage set, and its function is privacy/bed/bath. The Schlage B660 is a Grade 1 keyed single cylinder deadbolt with a cylinder outside, so it accepts a key and works as a standalone lock on a commercial opening. The Emtek 8483 Watford, 8583 Square and 8683 Disk are the same privacy bolt in different rosette styles. Choose an Emtek bolt for residential-style privacy where a matching passage set carries the latching, and the B660 where the door needs keyed control.
9) Which indicator deadbolt should be used on a fire rated opening instead of a Schlage B660?
The Schlage B660 is UL 10C listed and 3-hour fire rated as an auxiliary lock on A label single doors up to 4 feet by 8 feet, and UL 10B listed for neutral pressure doors, so on most rated single leaves it is already the answer. Where a Grade 2 fire rated indicator deadbolt is acceptable, the Hager 3216 is a thumbturn x occupancy indicator deadbolt with a 1 inch throw, fire rated, for 1-3/4 inch doors, and the Corbin Russwin CLX3320 NVSL is a fire rated Grade 1 option if the opening takes a lever lock rather than a bolt.
10) For a public restroom that needs both a latch and an occupancy indicator, what should be ordered instead of a Schlage B660 deadbolt?
The Schlage B660 is a deadbolt only, so a restroom door using it still needs a separate latching device to keep the door closed. The Falcon H2171 is a Grade 2 public restroom interconnected lock with an occupancy indicator and a single cylinder deadbolt in one device, storeroom/public restroom function, so the latch and the bolt install together. The Accentra AUYPL02 from the YPL Series is another single-device route, a Grade 1 privacy cylindrical lock with a visual status indicator, where a privacy button rather than a keyed cylinder controls the door.
11) Which indicator deadbolt should I use on a public restroom, a keyed one or a non-keyed privacy bolt?
Depends on whether staff need key override. The B660 is keyed outside, so a janitor or manager can unlock the room from the corridor, which is why it suits restrooms and single occupancy rooms in commercial buildings. If nobody needs to key in, the Arrow E50 is a non-keyed Grade 2 exit deadlock with a vacant/occupied indicator outside and covers 1-3/8 to 1-3/4 inch doors. For a room where the deadbolt should ride with the latchset rather than stand alone, the Falcon H2171 is a Grade 2 interconnected public restroom lock with an occupancy indicator and a single cylinder deadbolt.
12) What is the Grade 2 alternative to the Schlage B660 indicator deadbolt?
Two close ones. The Hager 3216 is a Grade 2 thumbturn by occupancy indicator deadbolt with the same 1 inch throw, fire rated, but built for 1-3/4 inch doors only. The Accentra D292 is a Grade 2 cylindrical indicator deadbolt covering 1-3/8 to 1-3/4 inch doors, which is the one to look at for older interior doors thinner than the B660's 1-5/8 inch floor. Cal-Royal's IND84 is the Grade 3 option on the same function. All three are lighter duty than the B660, which is a heavy duty commercial lock.
13) I need an occupancy indicator but the room already has a lever, not a deadbolt. What do I use?
An indicator lever rather than a bolt. The Corbin Russwin CLX3320 NVSL is a Grade 1 extra heavy duty privacy lever with a visual status indicator, fire rated, for 1-3/4 to 2 inch doors. The Accentra AUYPL02 in the YPL Series is another Grade 1 privacy cylindrical lock with a visual status indicator. The B660 is a deadbolt and bores separately from your existing latchset, so it adds a second hole in the door rather than replacing the lever.
14) Will the Schlage B660 key into the same system as the rest of my Schlage hardware?
Yes, if you order the matching keyway. The standard build takes a 6-pin conventional brass cylinder on the C keyway, and S123 is offered as the alternative. Factory master keying is available, and the B Series accepts all three cylinder formats, conventional, FSIC and SFIC, so it can be brought into an existing interchangeable core system. The trim also suites with nearly all Schlage and Von Duprin products for a consistent look across a building.
15) How does the Schlage B660 anchor into a wood frame so it survives a kick-in?
The strike side is where the work happens. A metal dust box reinforcer anchors into the frame with three 3 inch screws, which reach past the jamb into the stud rather than stopping in the trim. On the door side, the bolt is sintered steel with a hardened steel anti-saw pin, hardened ball bearings guard the mounting bolts against drilling, and a removable security shield blocks an ice-pick attack through the door. The free spinning trim collar resists a wrench or pry bar.
16) Is the Schlage B660 thumbturn ADA compliant, and is it Buy American compliant for a government job?
Both. The thumbturn design is ADA compliant, so it operates without tight grasping or twisting of the wrist, and the product is BAA compliant for federally funded work. It is a commercial, heavy duty lock rather than a residential one, which is generally what those specifications call for.
17) What is a lighter duty indicator deadbolt than the Schlage B660 for a low traffic interior door?
The Schlage B660 is a Grade 1 heavy duty deadbolt for commercial use. Stepping down, the Cal-Royal IND84 is a Grade 3 indicator deadbolt with a thumbturn x indicator function, and the Hager 3216 is a Grade 2 thumbturn x occupancy indicator deadbolt with a 1 inch throw for 1-3/4 inch doors. Neither is keyed on the outside the way the B660's single cylinder is, so use them where the room only needs to show occupied and no key override is required.
18) Is the Cal-Royal IND90-G2 a substitute for a Schlage B660 indicator deadbolt?
It covers a similar opening but not the same function. The Cal-Royal IND90-G2 is a Grade 1 indicator deadbolt with an ADA thumbturn and a thumbturn x indicator function. The Schlage B660 is a Grade 1 deadbolt with a cylinder outside and a thumbturn inside, and its thumbturn design is ADA compliant as well. The deciding difference is the outside face: the B660 takes a key there and accepts conventional, FSIC or SFIC cylinders, while the IND90-G2 shows an indicator. Match the B660 where the facility keys the room into an existing master system.
19) How far does the Schlage B660 trim ring stick out from the door face?
7/8 inch, in solid brass or bronze, with a broadly angled profile. That shallow projection matters where a door swings tight to a wall or where the deadbolt sits above a closer arm or a pull. Eleven finishes are offered, from 605 bright brass and 626 satin chrome through 622 matte black and 643E aged bronze, including a 626AM satin chrome antimicrobial for healthcare openings.
