Von Duprin 040191 Chexit Wiring Assembly

The Von Duprin 040191 is the Chexit wiring assembly, the wiring harness that connects the electronic components of a Von Duprin Chexit delayed-egress exit device. It's a genuine Von Duprin OEM part for the current-style Chexit system, specifically the version ordered after August 17, 2015, and it works across the 98/99, XP98/99, and 33A/35A series Chexit devices. When a Chexit unit needs its wiring harness replaced during service, or you're converting or repairing a device, this is the assembly that ties the controller, switches, and locking components together so the delayed-egress sequence operates as designed.

What Chexit is and what this wiring assembly does

Chexit is Von Duprin's delayed-egress system, built into the exit device itself. On a delayed-egress door, pushing the touchbar doesn't release the door immediately. Instead, it starts a timed delay (typically 15 seconds) with an alarm, then releases, which lets a facility control unauthorized exits while still meeting life-safety egress codes. That's why Chexit shows up in behavioral health, memory care, maternity wards, and retail loss-prevention, anywhere you need to slow an exit to prevent elopement, abduction, or theft without trapping anyone.

The 040191 wiring assembly is the harness that carries power and signal between the Chexit electronics. Without a correct, intact harness, the delayed-egress sequence can't function reliably. Because Chexit is life-safety hardware governed by code, using the genuine Von Duprin assembly rather than a substitute keeps the device operating the way it was listed and tested.

The 8/17/2015 date split, why it matters

This is the single most important thing to confirm before ordering, because Von Duprin changed the Chexit wiring style. The 040191 is for Chexit devices ordered after August 17, 2015. Units built before that date use a different harness, so ordering by the date your device was made (not just the series) is how you avoid getting a harness that won't connect. If you don't know your device's vintage, check the device label or the original order paperwork, and when in doubt, confirm before you buy. This one detail is where most wrong-part orders on Chexit harnesses happen.

For wiring diagrams and the installation sequence, the Von Duprin Chexit documentation and the 98/99 Series parts and wiring materials are the authoritative source, and we can point you to the right diagram and manual for your device so the harness is connected correctly.

Why order the genuine Von Duprin Chexit part

Delayed-egress hardware sits at the intersection of security and life safety, and it has to perform exactly to code in an emergency. The 040191 is the authentic Von Duprin harness designed for the current Chexit system, so it integrates cleanly and keeps the device's listing intact. Repairing a Chexit unit with the correct harness, rather than replacing the entire device or improvising a substitute, is both the compliant and the cost-effective path.

One thing to confirm before ordering: match the 040191 to a post-8/17/2015 Chexit device in a compatible series. If your unit predates that, or you're unsure, check first so the harness connects right the first time.
