Von Duprin 50228 – Frequently Asked Questions

1) Will the Von Duprin 050228 Chexit PCB kit work on my Chexit device if it was installed after 2015?
No. The 050228 PCB kit is the 15-second release board for Chexit units ordered before 8/17/2015. Later Chexit devices use a different board, so check the order date on the device before buying this one. If the opening went in after that cutoff, this is the wrong service part.
2) Which Von Duprin exit devices does the 050228 Chexit board fit?
It fits Chexit delayed egress hardware built on the Von Duprin 33, 35, 98 and 99 Series exit devices. That covers both the older 33/35 bodies and the current 98/99 rim, surface vertical rod and mortise chassis carrying the Chexit option. It is not a board for a non-Chexit device, there has to be a Chexit delayed egress system already on the door.
3) My delayed egress door alarms but never releases after the delay. Is replacing the Chexit circuit board the fix?
That is the failure the 050228 board addresses. Chexit sounds its local alarm, runs the timed delay, then releases the exit device latch. When the alarm and the delay work but the release does not, the electronic control on the board is the part that has stopped doing its job, and this kit restores that 15-second release function on 33/35/98/99 Series Chexit hardware. Confirm the device was ordered before 8/17/2015 first, since that is the generation this board serves.
4) Can I use this Chexit PCB kit on a fire rated exit door?
The 050228 Chexit PCB kit is not fire rated. Delayed egress is generally not permitted on fire rated openings anyway, since a fire door assembly has to release immediately. For a fire opening you want a fire exit device and its listed service parts, not delayed egress control.
5) Will an Accentra 7110/7120 exit device top latch replacement work in place of a Von Duprin 050228 Chexit PCB kit?
No. Those are two different classes of part. The Accentra 60-7010-0049-999 is a top latch replacement component for Accentra 7110 and 7120 exit devices, so it is a mechanical latching part for an Accentra device. The Von Duprin 050228 is a printed circuit board kit that restores the 15-second delayed egress release electronics in a Chexit system on Von Duprin 33, 35, 98 and 99 Series devices. A dead or damaged latch is a mechanical repair; a Chexit device that will not time out, alarm or release on the delay is a board-level repair. Diagnose which symptom you have before ordering, because neither part addresses the other's failure.
6) Is the Von Duprin 050228 a genuine Von Duprin part or an aftermarket board?
Genuine Von Duprin. The 050228 is the manufacturer's own replacement PCB kit for Chexit, built to Von Duprin's Grade 1 commercial standard. For a life safety device that controls egress, a factory board keeps the system as originally supplied rather than introducing an unlisted substitute into the circuit.
7) Will this Chexit board give me delayed egress on a pair of doors, or do I need a mullion?
The board only restores the delayed egress function on the device it is installed in, it does nothing about how a pair latches. On a pair with rim devices you still need a mullion, and each leaf that has to hold on delayed egress needs its own Chexit device and its own board. ZenSupply carries the Falcon 4023 steel mullion for double door exit device applications and the Falcon 525 aluminum mullion stabilizers if the pair is being sorted out at the same time.
8) My concealed vertical rod exit device with delayed egress is not latching at the top - is the Chexit PCB kit the fix?
Probably not. A top rod that does not throw or hold is a rod and latch issue: for Falcon concealed vertical rod devices, the equivalent service part is the Falcon 610061 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC exit devices. The Von Duprin 050228 Chexit PCB kit addresses the electronic side instead - the 15-second delayed egress release function on Von Duprin 33, 35, 98 and 99 Series devices. Match the part to the symptom: mechanical top latching gets a rod, a delay that will not run or release gets the board.
9) I need a part for a fire-rated delayed egress opening - is the Von Duprin 050228 or the Accentra 7110F latch the fire-rated option?
Neither carries a fire rating. The Von Duprin 050228 Chexit PCB kit is listed with a fire rating of No, and the Accentra 7110F top latch replacement component, 60-7010-0050-999, is also listed with a fire rating of No. If the opening is a labeled fire door, confirm the rating against the complete device assembly and its label rather than against either replacement component, since a service part is evaluated as part of the listed device it goes into.
10) My double doors with delayed egress hardware need a part - do I want the Chexit PCB kit or a mullion?
They solve unrelated problems. 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 mullion installations; both are structural pieces that give a pair of doors a latching point down the center of the opening. The Von Duprin 050228 is the Chexit printed circuit board kit that drives 15-second delayed egress release on 33, 35, 98 and 99 Series devices. Order the mullion when the opening itself needs the center post; order the 050228 when the delayed egress electronics on an installed Chexit device need to be restored.
11) Do I need a locksmith to install a Chexit replacement circuit board, or can building maintenance do it?
This is a service part for a technician. The 050228 board sits inside the Chexit device chassis and carries the delayed egress control and the alarm and release timing, so the device has to come off the door and the low voltage connections have to be made back correctly. Facilities staff who already service the 98/99 Series can do it; if nobody on site has opened a Chexit device before, put it on a hardware technician. Getting a delayed egress release wired wrong leaves an exit that will not release.
12) How many options do I have to specify when ordering the Von Duprin 050228 Chexit kit?
None. The 050228 is a single part number with no finish, hand or size to choose, because it is internal electronics. What you do have to get right before ordering is the generation: this is the 15-second release board for Chexit units ordered before 8/17/2015 on 33/35/98/99 Series devices.
13) Is a Grade 1 rating on the Von Duprin 050228 the same thing as a Grade 1 rating on a Falcon deadlatch part?
The Von Duprin 050228 Chexit PCB kit is rated Grade 1 and specified for commercial use. Among the comparable exit device service parts, the Falcon T Series 2-3/8 inch square corner deadlatch replacement part, FAL-23981160, is a T Series component and the Arrow 16RCR-27 is a 6/7-pin SFIC rim housing in the 24/25 Series. Those are cylinder and latch components serving a different function in the opening, so the useful comparison for a specifier is function first: the 050228 is the delayed egress control board, not a latch or a cylinder housing.
