Accentra AUCN 8834FL All Purpose Mortise Lockset – Grade 1 Security

Function Info: Latchbolt retracted by key outside, knob/lever inside. No knob/lever outside. Latchbolt can be held in retracted position by inside thumbturn cylinder. Deadlocking latchbolt. NOT UL listed. Not available with E3 or E4 escutcheons.
The Accentra AUCN 8834FL (formerly Yale 8800 Series) is a heavy-duty All Purpose Lock Function mortise lockset built for commercial and institutional openings. It is certified to ANSI/BHMA A156.13 Series 1000, Grade 1 -- the highest operational and security grade the standard defines -- and carries the Augusta (AUCN) lever on the Camden 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 626 Satin Chrome, it is field reversible and ships with the door prep and installation drawings for the trim shown.
Function Details: All Purpose Lock
- Key Outside, Lever Inside: Latchbolt retracted by key outside, knob/lever inside — entry from outside is by key; the inside lever works the latch without one, so nobody is ever held in.
- Cylinder Outside, No Lever: No knob/lever outside — nothing to grip on the outside face -- the key alone works the latch from there, and the trim you order is the inside trim.
- Latchbolt can be held in retracted position by inside thumbturn cylinder
- 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.
- Not UL Listed -- Not for a Fire Door: NOT UL listed — this function carries no UL fire listing, so it cannot go on a labelled fire opening; that door needs a listed function instead.
- Not Offered on Every Escutcheon: Not available with E3 or E4 escutcheons — the factory does not build this function with those two plates, so the trim has to be chosen from the ones it is offered in.
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.
- 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.
- Field Reversible: Furnished right hand and re-handed in the field, so one lock suits either door swing without a return.
- 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.
