Von Duprin 050254-00 – Frequently Asked Questions

1) What Von Duprin exit devices does the 05025 LX switch assembly fit?
The 05025 LX switch assembly is built for three Von Duprin platforms: the 2227 Vertical Rod Exit Device, the 33A/35A Series Rim Exit Device, and the 98/99 Series Rim Exit Device. If the device on your door is one of those three, this is the switch that goes back in it. Anything outside that list, don't order this part.
2) Von Duprin 05025 LX switch comes in 36 inch and 48 inch, which one do I order?
Order the length that matches the device it is going into. The 05025 LX switch assembly is offered in 36 inch and 48 inch, and that figure tracks the exit device size, not the door itself. Pull the device off the door or check the original order paperwork before you commit, because the two are not interchangeable in the field.
3) What does the LX switch actually do on a Von Duprin exit device?
LX is the latch monitoring switch. It reports the state of the device electrically, which is what feeds your access control or life safety panel the signal that the door has been operated. When that signal drops out and the mechanical device still works fine, the switch assembly is usually what failed. The 05025 is the replacement for that switching function on the 2227, 33A/35A, and 98/99 devices.
4) My Von Duprin 99 rim device stopped signaling the access control panel, do I need a whole new exit device?
Not necessarily. On a 98/99 Series rim device, the LX switching is a serviceable assembly, so a failed monitor signal with a mechanically sound device is a switch replacement, not a device replacement. The 05025 goes in as the service part. Same story on a 33A/35A rim device or a 2227 vertical rod.
5) Can I use the 05025 LX switch on a Von Duprin concealed vertical rod or mortise exit device?
No. The 05025 covers the 2227 surface vertical rod plus the 33A/35A and 98/99 rim devices. A concealed vertical rod device or a mortise exit device takes a different switch assembly for its series, so match the part to the exact device family stamped on the chassis before ordering.
6) Is the Von Duprin 05025 a genuine OEM part or an aftermarket switch?
Genuine Von Duprin, part number 299-19, sourced from the manufacturer and built to their spec for the 2227, 33A/35A, and 98/99 devices. On an electrified exit device tied into life safety, that matters more than on a piece of trim, because a switch that seats slightly differently changes when the signal makes and breaks.
7) I'm standardizing exit device parts across a building with mixed Von Duprin 99 and 2227 devices, can one switch assembly cover both?
Yes, on the switch itself. The 05025 LX assembly serves the 2227 vertical rod and the 98/99 rim device, along with 33A/35A rim, so a facility running a mix of those platforms stocks one switch part rather than three. What you still have to track per door is length, since the assembly comes in 36 inch and 48 inch.
8) Is the 05025 the whole electrified kit or just the switch?
Just the LX switch assembly. It is the switching component only, not the device chassis, not the rail, not the trim or power transfer. If your repair also needs a hinge transfer or a power supply to get voltage to the door, those are separate items.
