The 8200 functions people get wrong

The common Sargent 8200 functions, storeroom, office and classroom, are easy to pick. The next group is where orders go sideways: the 8224 room door, the 8225 dormitory, the 8267 institutional privacy and the 8289 holdback. They look the same from across the hall. They behave nothing alike, and two of them carry a deadbolt. All four share the 8200 platform: a heavy-duty cast stainless steel chassis, ANSI/BHMA Grade 1, a standard conventional mortise cylinder included, and a 10-year limited warranty, per the catalog.

8224: hotel guest, with deadbolt

8224-LNL-26D is listed under the name Room Door with Lever Trim and Deadbolt, and the function text calls it Hotel Guest. The key detail: the guest key overrides the deadbolt, and emergency and construction master keys are available. In a hotel or any building that rents rooms, that matters. A guest throws the deadbolt for the night, and staff with the right key can still get in during an emergency.

This is a deadbolt-equipped lock designed around who holds which key. Before you order, decide the master key plan, because the function only pays off if the keying fits it. A construction master that opens every room during a renovation and then stops working at turnover is the kind of thing this function was built for.

8225: dormitory or exit, with deadbolt

8225-LNL-26D is the Dormitory function with a deadbolt. The outside lever is locked by the inside thumbturn and unlocked by key from outside. The inside lever is always free. So the occupant controls the lock from inside, and the key opens it from the corridor.

That sounds like the hotel lock, and it is close. The difference is in the story the catalog tells: the 8224 is built around a guest key that overrides the bolt, and the 8225 around the occupant turning the thumbturn. If you have an access policy for a residence hall, read both descriptions against it, because the choice is a policy choice more than a hardware one. The catalog also notes that the 8200 drops into the same prep as an older Sargent mortise lock, with the same backset and strike, which saves door work on a retrofit.

8267: institutional privacy

8267-LNL-26D is the Institution function. Both levers are locked and unlocked by key only. There is no thumbturn and no push-button. Nobody can lock this door from inside by hand, and the inside is not free: the key operates both sides.

That is exactly what a secure unit wants. A room where an occupant should not be able to lock staff out, or where staff need control of both sides, gets this lock. It is the wrong lock for an ordinary office, and it is the wrong lock for any door where someone inside has to leave without a key. Do not put it on a path of egress that your building code treats as free exit. Check with the authority having jurisdiction first.

8289: holdback

8289-LNL-26D is listed as the Holdback mortise lock. The catalog page for this part does not describe the lever behavior in detail, so I will describe what a holdback function does in general. It lets the latchbolt be held retracted so the door can stand without latching. It is the answer for a lobby or entrance door that is propped open during business hours and secured at night. Confirm with us that the 8289 is the right function for your opening before you order.

Side by side

Function	Deadbolt	Inside control	Typical door
8224 hotel guest	Yes	Guest key overrides the bolt	Guest rooms
8225 dormitory	Yes	Thumbturn locks outside lever	Residence hall rooms
8267 institution	No	None, key only both sides	Secure units and controlled rooms
8289 holdback	Not stated	Not stated on this page	Doors held open by day

Before you order

Write down the key plan first. For the 8224 and 8225, that means who carries the guest or master key and what happens when one is lost. For the 8267, it means who is allowed to open the room at all. Then confirm the lever trim and finish with the rest of the building. The part numbers here end in LNL and a finish code, 26D for satin chrome, and the catalog lists a less-cylinder version of each part if you key to your own system.

Mistakes I see

• Using an institutional privacy lock where staff and occupants both need egress. No inside thumbturn means nobody locks it from inside, and egress rules still apply.
• Ordering a dormitory lock without a master key plan. Staff then carry fifty keys.
• Assuming "room door" means a simple privacy lock. It is a hotel guest function with a deadbolt.
• Skipping the cylinder question. One is included. Systems with their own cores need the less-cylinder version.
• Guessing on holdback. Ask before you order.

Common questions

What does the Sargent 8224 do that the 8225 does not?

The 8224 is listed as a hotel guest function where the guest key overrides the deadbolt. The 8225 is a dormitory function where the inside thumbturn locks the outside lever.

Can the Sargent 8267 be locked from inside?

Not by hand. Both levers work by key only, with no thumbturn or push-button.

Do these locks include a cylinder?

Yes, a standard conventional mortise cylinder. A less-cylinder variant exists.

What grade are they?

ANSI/BHMA Grade 1 per the catalog.
