The Accentra ARSL SL8808FL (formerly Yale SL8800 Series) is the heavy-duty security version of the 8800 Classroom Lock Function mortise lockset, built for openings where heavy abuse or vandalism is a concern. It is certified to ANSI/BHMA A156.13 Series 1000, Operational Grade 1, and the SL8800 with its security escutcheon also meets Security Grade 1. It carries the Arcadia (ARSL) lever on the SL security escutcheon.

Built for openings that are opened and closed thousands of times a year, it uses a wrought steel, zinc dichromate plated case, 3/8" solid steel (heat treated) hubs and a 3/4" throw stainless steel anti-friction latchbolt. Supplied in 630 Satin Stainless Steel, the Arcadia lever is handed -- give the hand when ordering -- and it ships with the door prep and installation drawings for the trim shown.

The SL security escutcheon is what sets this lock apart: heavy duty escutcheon trim that is flat against the door to resist damage and vandalism; lever attached directly to escutcheon for added security; thrubolted security head screws offer added protection. The SL8800 is furnished in 630 Satin Stainless Steel only; levers are Nickel Plated to match Stainless Steel.

Function Details: Classroom Lock (ANSI/BHMA F05)

• Typical Application: For classroom, office, or utility room doors — the openings this function is written for.
• Outside Lever Works Until It Is Locked: Latchbolt retracted by knob/lever either side, except when outside knob/lever is locked by key — the outside lever retracts the latchbolt normally, and stops the moment the lock is set against it.
• Life-Safety Free Egress: Inside knob/lever always active — the inside lever is never locked, so a single motion always gets a person out.
• Key Entry While the Outside Stays Locked: Latchbolt can be retracted by key when outside knob/lever is locked — with the outside lever locked, the key withdraws the latchbolt for that one entry and leaves the outside lever locked behind it, so the room does not have to be unlocked to let someone in.
• Free Egress, Outside Unaffected: Operating inside knob/lever retracts latchbolt, but outside knob/lever remains locked — anyone inside leaves by turning the inside lever in a single motion, and doing so does not unlock the outside lever behind them.
• Anti-Shim Protection: Deadlocking latchbolt — a small plunger beside the latchbolt rides the strike when the door closes; with it depressed the latchbolt cannot be shimmed back with a card.

Key Performance Features

• ANSI/BHMA Grade 1 Certified: Independently tested to the highest operational and security grade the standard defines, for long service life in demanding commercial and institutional openings.
• 3-Hour Fire Rating: UL and cUL listed for use on fire-rated door assemblies, so the opening stays code compliant.
• Accessible Operation: The lever is operable without tight grasping, pinching or wrist twisting, which is what ADA 404.2.7 requires of an accessible opening.
• Handed Lever -- Specify the Hand: This lever design is made to a hand, so give the hand on the order; the lock body itself is field reversible.
• Anti-Friction Latchbolt: A stainless steel one-piece latch that closes quietly and resists the drag that wears a latch out on a high-traffic door.
• Heavy-Duty Hubs: Heat-treated solid steel through the point that takes every turn of the lever, which is where a lighter lock fails first.
• Mechanical Warranty: Backed for the long term against defects in the mechanical lock.
