Von Duprin 41166 – Frequently Asked Questions

1) Which Von Duprin exit devices does the 041166 QELX baseplate conversion kit work with?
The 041166 QELX baseplate conversion kit is built for Von Duprin AX exit devices in the 33A/35A and 98/99 Series. If the device on your door is one of those families, the kit swaps the baseplate assembly over to Quiet Electronic Latch Retraction without replacing the whole device. It is not a fit for non-AX devices or other Von Duprin series.
2) I have an older Von Duprin solenoid EL latch retraction device that is loud. Can I convert it to QELX instead of buying a new exit device?
That is exactly what this kit is for. Von Duprin recommends the EL conversion when you are upgrading an existing solenoid-driven latch retraction system, and the 041166 baseplate kit does it in the field on a compatible AX device. Your existing rail, trim and door prep stay put, which is the point of a field conversion: less downtime and no re-prep of the door.
3) Is the Von Duprin 041166 a drop-in for a 3 foot AX device only, or will it fit a 4 foot opening?
Width matters here. The 041166 is configured for AX 3 foot devices. For a 4 foot AX device you need the 041169 kit instead, which also carries Allegion Connect. Ordering the 3 foot kit for a 4 foot rail leaves you short.
4) What is the difference between the 041166 and the 041169 QELX kit?
Both are QELX field conversion kits for AX exit devices. The 041166 is configured for AX 3 foot devices with standard wiring, which Von Duprin recommends when upgrading from existing solenoid-driven latch retraction. The 041169 covers AX 4 foot devices and adds Allegion Connect capability for integrated access control applications. Match the kit to the device width first, then to whether the opening needs the Connect option.
5) Can a Falcon exit device part be used to add quiet electric latch retraction to a Von Duprin AX device?
No. The Von Duprin 041166 is a QELX baseplate conversion kit that converts solenoid-driven latch retraction to Quiet Electronic Latch Retraction on AX devices, and it is built for the 33A/35A and 98/99 Series exit devices. The Falcon parts in the same family are mechanical components for Falcon hardware: the Falcon 610061 is a 24 Series Monarch concealed vertical top rod for F-25-C and F-25-CWDC devices, and the Falcon 23981160 is a 2-3/8 inch square corner deadlatch replacement part for the T Series. None of them carry an electrified latch retraction function or fit Von Duprin chassis. For an electric latch retraction upgrade on a Von Duprin AX device, the 041166 baseplate kit is the correct part.
6) How much wiring comes with the Von Duprin 041166 conversion kit?
It ships with 3 foot standard wiring, sized for typical door and frame wiring runs. That covers a normal run from the device out through the hinge-side transfer to the frame. Long runs back to a power supply are handled by the building wiring downstream of that connection, not by the kit itself.
7) Why would a hospital or school choose QELX over standard electric latch retraction on an exit device?
Noise. Standard solenoid-driven latch retraction makes an audible clack every time it fires, which is a problem in patient areas, classrooms and testing rooms. QELX cuts that operational noise, and the 041166 baseplate kit is the way to get an already-installed AX device there. Healthcare and educational facilities are the two applications Von Duprin calls out for it.
8) My exit device latching is failing - do I need the Von Duprin 041166 or a latch replacement part?
Those solve different problems. The Von Duprin 041166 is a conversion kit that changes how the latch is retracted electrically, upgrading solenoid-driven latch retraction to Quiet Electronic Latch Retraction on AX devices; it does not replace the latch itself. If the mechanical latch is worn, the equivalent repair on other platforms is a latch component such as the Accentra 7110/7120 exit device top latch replacement component or, for fire-rated devices, the Accentra 7110F top latch replacement. Diagnose whether the fault is mechanical latching or the retraction motor before ordering, because the 041166 addresses only the retraction side.
9) For a pair of doors with electric latch retraction, does the 041166 kit cover the mullion as well?
No. The Von Duprin 041166 QELX baseplate conversion kit handles the latch retraction upgrade on the exit device itself for 33A/35A and 98/99 Series AX hardware. A double-door opening still needs its own mullion hardware, which is ordered separately - for example the Falcon 4023 steel mullion is a mullion for double door exit device applications, and the Falcon 525 aluminum mullion stabilizers are exit device accessories for that role. Plan the mullion as a separate line item from the conversion kit.
10) I need a mullion or a replacement rod for a pair of exit doors, not a latch retraction kit. What should I be looking at?
The 041166 is an electrified latch retraction conversion and does nothing for mechanical hardware. For a pair of doors with rim devices you would want a mullion such as the Falcon 4023 steel mullion, with Falcon 525 aluminum mullion stabilizers if you need them. For a concealed vertical rod replacement on a Falcon 24 Series Monarch device, the 610061 top rod covers F-25-C and F-25-CWDC devices.
11) If I want keyed access control instead of electric latch retraction, is the 041166 the right kit?
No. The Von Duprin 041166 is a QELX baseplate conversion kit whose function is electronic latch retraction on AX exit devices - it is the powered dogging and remote release path, not a cylinder change. For mechanical keyed control through a rim device you are looking at a rim cylinder housing instead, such as the Arrow 16RCR-27 SFIC rim housing for 6 or 7-pin cores in the 24/25 Series. The two can coexist on one opening but they are separate orders addressing separate functions.
