Von Duprin 90005 – Frequently Asked Questions

1) What is a dog key used for on a Von Duprin exit device?
The Von Duprin 227 dog key is the hex wrench that operates the dogging mechanism on a mechanically dogged exit device. Insert it in the dogging hole on the device, turn it, and the push pad stays depressed with the latch held retracted, so the door pushes open freely without releasing the latch each time. Turn it back and the device latches normally again. It's the part that gets lost off the maintenance ring, which is why it's sold as a replacement part in a package of 2 or a package of 10.
2) Will the Von Duprin 227 dog key fit my 99 Series rim device?
Yes. The 227 dog key is the 5/32 inch key for Von Duprin 22, 33, 35, 98 and 99 Series exit devices, so a 99 rim device with mechanical dogging takes it. Same key across all five series, which is why one on the key ring covers a building running mixed Von Duprin hardware.
3) Can I dog a fire rated exit device with this key?
No. Fire rated exit devices do not have mechanical dogging, so there is no dogging hole for the 227 key to engage. Holding a fire door's latch retracted defeats the door. The 227 is for non-fire-rated Von Duprin 22, 33, 35, 98 and 99 Series devices, and the key itself carries no fire rating. If your opening is fire rated and you need free push-through during business hours, you need an electric latch retraction device, not a dog key.
4) I need to stop a pair of doors from latching during business hours - is a dog key the right part or do I need a mullion?
Those solve different problems. The 227 dog key is what holds the pushbar of a Von Duprin 22, 33, 35, 98 or 99 Series device depressed so the latch stays retracted and the door pushes free - that is the hours-of-operation function. A mullion is a vertical post that gives a pair of doors something to latch against in the first place: the Falcon 4023 is a steel mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are accessories for exit device mullions. If the doors already latch correctly and you only want them free-swinging on a schedule, the dog key is the part. If you are building or servicing the double door opening itself, that is mullion work.
5) Is a 5/32 hex allen wrench the same as a Von Duprin dog key?
The 227 is a 5/32 inch key, so the drive size matches a 5/32 hex wrench, but the 227 is formed as a dog key for the dogging hole rather than as a straight L-wrench. A generic allen key of the right size will turn the mechanism in a pinch; the 227 is the part Von Duprin specifies for the 22, 33, 35, 98 and 99 Series and it's what belongs in a service kit.
6) Do I need a dog key or a mullion for a pair of doors with exit devices?
They solve different problems. The 227 dog key holds a single device's latch retracted so the door free-swings, and it works on Von Duprin 22, 33, 35, 98 and 99 Series devices. A removable mullion is structural: it gives a pair of doors the vertical member a rim device latches into, so both leaves get rim hardware instead of vertical rod devices. If you're outfitting a pair, the Falcon 4023 steel mullion is the part for that, and the Falcon 525 aluminum mullion stabilizers go with mullion applications. A dog key does nothing for a pair that has no mullion.
7) My exit device won't latch after someone used the dog key. What do I do?
That's usually the device still dogged rather than a failure. On a mechanically dogged Von Duprin 22, 33, 35, 98 or 99 Series device, the push pad sits depressed and the latch stays retracted until the 227 key is turned back the other way in the dogging hole. Put the 5/32 key in and reverse it; the pad should release and the latch project. If the pad releases but the latch still doesn't catch, the problem is in the latch or strike, not the dogging.
8) Our exit device will not stay dogged - do we replace the key or a rod or latch component?
Start with the key. On Von Duprin 22, 33, 35, 98 and 99 Series devices the 227 is the 5/32 inch key that turns the dogging mechanism, and a rounded or worn key is the usual reason dogging will not hold. It comes in a package of 2, so a service van carries a spare. If the trouble is instead that the device is not latching or not retracting properly, that points at the latching train rather than the dogging key - the parts that address that are device specific, such as the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices on Falcon concealed vertical rod hardware, or the Accentra 7110/7120 exit device top latch replacement component on Accentra devices.
9) Does a dog key have anything to do with keying the exit device cylinder?
No, and the word key causes this mix-up regularly. The Von Duprin 227 is a 5/32 inch dogging key - a hex tool that holds the pushbar down, with no bitting, no keyway and no relation to any keying system. Cylinder work on rim exit hardware is a separate part: the Arrow 16RCR-27 is an SFIC rim housing in 6/7-pin for the Arrow 24/25 Series, which is the component that accepts an interchangeable core. If a locksmith is keying the opening, the dog key is not part of that scope; it is the maintenance tool for the dogging function.
10) We are standardizing exit hardware on a fire rated opening - does the dog key apply there?
The Von Duprin 227 dog key carries no fire rating, and fire rated exit devices are not dogged - the latch has to stay active. It is a commercial Grade 1 maintenance part for the dogging function on non-fire 22, 33, 35, 98 and 99 Series devices. Several of the other exit device service components a facility stocks are likewise non-fire rated, including the Accentra 7110/7120 and Accentra 7110F top latch replacement components. For a facility running both fire and non-fire openings, buy the dog keys against the non-fire door count, in packages of 2 or 10 depending on how many service kits you are building.
11) How many Von Duprin 227 dog keys should I order for a building?
Two order quantities are offered: a package of 2 and a package of 10. Two suits a single service truck or a small property where one key stays on the ring and one is the spare. The package of 10 is the one to buy when you're stocking a maintenance shop, issuing a key per technician, or standardizing across a campus where every device is Von Duprin 22, 33, 35, 98 or 99 Series and one key type covers all of them.
12) Is the Von Duprin 227 dog key rated for commercial use?
It's a Grade 1 commercial part, matching the Grade 1 exit devices it serves. Grade 1 is the heaviest ANSI/BHMA duty tier and the one written into most institutional and commercial specs, so the 227 is what to put on a spec-compliant maintenance program for schools, hospitals, and municipal buildings running Von Duprin 22, 33, 35, 98 or 99 Series hardware.
