Schlage B660P 626 OS-OCC – Frequently Asked Questions

1) What does the OS-OCC option on a Schlage B660 actually show, and which side is it on?
The indicator reads VACANT / OCCUPIED and sits on the OUTSIDE face of the door, so someone in the corridor can see whether the room is in use before trying the handle. Inside, the occupant throws the bolt with a thumbturn; outside there is a keyed cylinder for staff override. That combination, thumbturn inside by cylinder outside, is the B660 function.
2) Is the Schlage B660 indicator deadbolt Grade 1, and does that change with the cylinder I pick?
Grade matters here and it tracks the cylinder. With a conventional cylinder the B660 is ANSI/BHMA A156.5 Grade 1 certified. Order it FSIC and the certification is Grade 2; SFIC drops it to Grade 3. If your spec sheet says Grade 1 deadbolt, you need the P6 conventional cylinder, not one of the less-core interchangeable options.
3) Can I use a Schlage B660 occupancy indicator deadbolt on a fire rated door?
The B Series deadbolts are UL 10C listed and 3-hour fire rated as auxiliary locks, for A label single doors up to 4 feet by 8 feet. They also carry a UL 10B listing for neutral pressure doors. Auxiliary is the operative word: this is a deadbolt used alongside the primary latching hardware on the opening, not in place of it.
4) What do I have to specify when ordering a Schlage B660-OS-OCC, and what shows up in the box?
Three choices decide the order. Cylinder: P6 6-pin conventional in the C keyway, J for FSIC less core, or B for SFIC less core (the less-core options ship without a core, so you supply it from your own system). Finish: eleven of them, 605 bright brass, 606 satin brass, 609 antique 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. Keying: keyed different is standard, keyed alike if you want one key across several locks, or none when you have picked a less-cylinder option. Keyway is C standard or S123. A conventional-cylinder lock ships with two nickel silver cut keys, and the metal dust box reinforcer with three 3 inch screws is part of the package.
5) Will a Schlage B660 drop into the existing deadbolt prep and strike on my door?
Check three numbers against what is in the door. Bolt housing diameter is 1 inch, so it needs a 1 inch cross bore. The faceplate is 1-1/8 by 2-1/4 inches with square corners and the strike is 1-1/8 by 2-3/4 inches, also square corner. Backset is 2-3/4 inches fixed on the standard build, though Schlage offers adjustable 2-3/8 or 2-3/4 inch and other fixed backsets. If the existing prep has radius corners, ANSI strikes, or a 2-3/8 inch backset, order the matching option rather than chiseling the jamb.
6) Can I key a Schlage B660 into the master key system already running in my building?
Yes, in several ways. The B660 accepts all three cylinder formats, conventional, FSIC and SFIC, so if your facility already runs interchangeable cores you order the J or B less-core version and drop your own core in. Sticking with conventional gets you a 6-pin solid brass cylinder in the C keyway as standard, with S123 also available, and factory master keying can be set up at order. Order several keyed alike if a maintenance crew should carry one key for the whole run.
7) The door is 1-3/8 inch thick. What indicator deadbolt fits when the Schlage B660 does not?
The Schlage B660 door range starts at 1-5/8 inch with a Conventional or FSIC cylinder and 1-3/4 inch with SFIC, so a 1-3/8 inch door falls below it. Two indicator deadbolts in the comparable set reach that thickness: the Accentra D292, a Grade 2 cylindrical deadbolt with thumbturn and indicator function rated 1-3/8 inch to 1-3/4 inch, and the Arrow E50, a Grade 2 non-keyed exit deadlock with an outside VACANT/OCCUPIED indicator, also 1-3/8 inch to 1-3/4 inch. The D292 keeps the keyed side; the E50 is thumbturn x indicator only.
8) What is the closest Grade 1 alternative to the Schlage B660-OS-OCC occupancy indicator deadbolt?
Within the indicator deadbolt group, the Cal-Royal IND90-G2 is the closest peer on grade and function: it is a Grade 1 indicator deadbolt with a thumbturn x indicator function and an ADA thumbturn. The difference that matters is the outside face. The Schlage B660-OS-OCC is a keyed single cylinder deadbolt, cylinder x thumbturn, so the outside gets a key override alongside the VACANT/OCCUPIED indicator. The Cal-Royal is thumbturn x indicator, with no key on the outside. If the opening needs staff key access, the B660-OS-OCC is the one that carries it.
9) Is there a simpler indicator deadbolt for a single-occupancy restroom that does not need a key on the outside?
Yes. The Arrow E50 is a Grade 2 exit deadlock with a VACANT/OCCUPIED indicator on the outside and a non-keyed function, thumbturn x indicator, for doors 1-3/8 inch to 1-3/4 inch thick. The Cal-Royal IND84 is a Grade 3 indicator deadbolt with the same thumbturn x indicator arrangement. Both give the occupant the same throw-the-bolt, read-the-indicator behavior as the Schlage B660-OS-OCC without a cylinder to key or a keyway to pick in a master system. Choose the B660-OS-OCC when the outside needs a keyed single cylinder for staff entry.
10) What should I use instead if the opening needs a latch and a lever, not just a deadbolt?
The Schlage B660-OS-OCC is a deadbolt only, with a lock function of deadbolt and no latching lever, so an opening that needs a lever plus indicator needs a different device. The Corbin Russwin CLX3320 NVSL is a Grade 1 extra heavy duty privacy/bedroom/bathroom visual status lever lock with an indicator, fire rated, for doors 1-3/4 inch to 2 inch. The Accentra AUYPL02 YPL Series is a Grade 1 privacy cylindrical lock with a visual status indicator. For a restroom that needs both a latching lock and a deadbolt from one device, the Falcon H2171 is a Grade 2 public restroom interconnected lock with occupancy indicator and a single cylinder deadbolt.
11) Which indicator deadbolt carries a fire rating for a labeled opening?
The Schlage B660 is UL 10C listed and 3-hour fire rated as an auxiliary lock for A label single doors up to 4 feet by 8 feet, and UL 10B listed for neutral pressure doors. Among the peers, the Hager 3216 is a Grade 2 thumbturn x occupancy indicator deadbolt with a 1 inch throw for 1-3/4 inch doors and carries a fire rating, and the Corbin Russwin CLX3320 NVSL lever lock is fire rated as well. If the drawing calls for Grade 1 on a labeled door, the B660 is the Grade 1 member of that group.
12) Which occupancy indicator deadbolt accepts an interchangeable core?
The Schlage B660-OS-OCC is offered with an SFIC less core preparation, an FSIC less core preparation, and a 6-pin Conventional cylinder in the C keyway, so a facility already stocking small format or full size cores can key it into the existing system. Among the indicator deadbolt peers, the Cal-Royal IND90-G2, Cal-Royal IND84, Accentra D292, Arrow E50 and Hager 3216 are thumbturn x indicator devices rather than interchangeable core keyed deadbolts. Note that Schlage certifies Grade 1 with the Conventional cylinder, while FSIC is Grade 2 and SFIC is Grade 3.
13) Should I use an indicator deadbolt or an indicator privacy lever for a single-occupancy restroom?
Two different approaches. An indicator deadbolt like the B660 is an auxiliary bolt: it throws a separate bolt above the existing latch and shows VACANT or OCCUPIED outside, and staff get in with a key. An indicator privacy lever such as the Corbin Russwin CLX3320 NVSL puts the status display and the privacy function into the lockset itself, one piece of hardware instead of two, and the Accentra AUYPL02 YPL Series is a Grade 1 privacy cylindrical with visual status indicator in the same vein. Choose the deadbolt when the door already has serviceable latching hardware you are keeping, or when you want a keyed override on a bolt that resists forcing. Choose the lever lock when you are replacing the whole lockset and want one hole and one operation.
14) What is the difference between the Schlage B660 indicator deadbolt and a Grade 2 indicator deadbolt like the Hager 3216 or Accentra D292?
Grade and door range separate them. The B660 with a conventional cylinder is ANSI/BHMA A156.5 Grade 1, heavy duty, and covers 1-5/8 to 2 inch doors with conventional or FSIC cylinders. The Hager 3216 is a Grade 2 thumbturn by occupancy indicator deadbolt with a 1 inch throw, listed for 1-3/4 inch doors and fire rated. The Accentra D292 is a Grade 2 thumbturn by indicator deadbolt covering 1-3/8 to 1-3/4 inch doors. If your opening is thicker than 1-3/4 inches, the Schlage is the one with the range for it.
15) I need an occupancy indicator deadbolt but I do not want it keyed. What should I look at instead of the B660?
The B660 is a keyed single cylinder unit, so if you do not want a key on the outside it is the wrong function. Within the same Schlage family the B680 door bolt is thumbturn by no exterior trim, keyless. Across brands, the Arrow E50 is a Grade 2 exit deadlock with a VACANT/OCCUPIED indicator outside and no key at all, and the Falcon D271 is a Grade 2 one-sided deadbolt with occupancy indicator, medium duty.
16) How secure is the Schlage B660 bolt against forced entry and drilling?
The bolt is solid sintered steel with a hardened steel anti-saw pin insert, thicker than most Grade 1 deadbolt bolts, throwing 1 inch. Hardened steel ball bearings shield the mounting bolts from drilling. The cylinder collar spins free and is broadly angled to defeat wrenching and prying, and a removable security shield blocks ice-pick attack through the door. In a wood frame, the metal dust box with three 3 inch screws reaches past the jamb into the framing, which is what stops a kick-in. The fixed 2-3/4 inch backset also resists tampering compared with the adjustable version.
17) Will a Schlage B660 deadbolt match the other Schlage hardware and exit devices already in my building?
Suiting is one of the reasons to stay in the B Series. The B600 deadbolts suite with nearly all Schlage and Von Duprin products, and the trim ring is a 7/8 inch solid brass or bronze piece in a shallow, broadly angled profile, so it sits close to the door face instead of standing proud next to your lever trim. Eleven finishes cover the usual commercial standards, 626 satin chrome and 613 oil rubbed bronze among them, and 626AM is the antimicrobial satin chrome if you are specifying for healthcare.
18) Does the Schlage B660 qualify for a Buy American Act federal or government job?
BAA compliance is stated for the B Series deadbolts, which is what a government or federally funded project needs on the submittal. The thumbturn design is also ADA compliant, so the inside operation meets accessibility requirements without a separate specification.
19) Is the Schlage B660 with indicator suitable for a high-traffic public restroom, or is that a different lock?
Heavy duty and Grade 1 with a conventional cylinder, so the B660 stands up to public traffic, but it is an auxiliary deadbolt: the door still needs its own latching hardware and the user has to throw the bolt deliberately. If you want the occupancy indication and the latching in one device, the Falcon H2171 is a public restroom interconnected lock with occupancy indicator and a single cylinder deadbolt, Grade 2. Use the B660 where the existing lockset stays and you are adding secure, keyed-override privacy to it.
20) Do Emtek indicator privacy bolts work as a substitute for a Schlage B660-OS-OCC?
They solve a different opening. The Emtek 8383 Wilshire, 8483 Watford, 8583 Square and 8683 Disk are thumbturn privacy bolts with double rosettes and an indicator, intended for use with a Brass Passage Set, and their function is privacy/bed/bath. There is no key on the outside and they depend on a companion passage set for the latching. The Schlage B660-OS-OCC is a commercial, heavy duty, Grade 1 keyed single cylinder deadbolt with a cylinder outside and thumbturn inside, and it operates on its own. Where the specification calls for a keyed commercial deadbolt, the Emtek bolts are not an equivalent.
21) I am standardizing occupancy indicator deadbolts across a facility. How do the grades line up?
Across the indicator deadbolts, the Schlage B660 is Grade 1 and heavy duty, ANSI/BHMA E0151, with a cylinder x thumbturn function. The Cal-Royal IND90-G2 is also Grade 1, thumbturn x indicator. At Grade 2 sit the Accentra D292 thumbturn x indicator, the Arrow E50 thumbturn x indicator, the Hager 3216 thumbturn x occupancy indicator, and the Falcon D271, a medium duty one-sided deadbolt with occupancy indicator. The Cal-Royal IND84 is Grade 3. Facilities that write a Grade 1 heavy duty standard and want a keyed outside face land on the B660; back-of-house doors that only need the indicator can drop to the Grade 2 or Grade 3 members.
22) What is the difference between the Falcon D271 and the Schlage B660-OS-OCC?
The Falcon D271 is a Grade 2 medium duty deadbolt with an occupancy indicator and a one-sided function, thumbturn inside. The Schlage B660-OS-OCC is Grade 1, heavy duty, and a keyed single cylinder deadbolt with a cylinder on the outside and a thumbturn inside, supplied with two keys. Both put the occupancy indication on the outside face; only the B660-OS-OCC gives maintenance or security staff a key override from the corridor side, and its cylinder is a 6-pin Conventional cylinder in the C keyway.
