PDQ 639026 – Frequently Asked Questions
1) What does the PDQ 639026 MLR kit do, and which exit devices does it fit?
PDQ 639026 is the Motorized Latch Retraction (MLR) kit, a conversion part that electrically retracts and holds back the latch on an installed PDQ exit device. It is a genuine PDQ part for the 6300 Series wide stile and 6400 Series narrow stile exit devices, so an existing device can be upgraded in place rather than replaced.
2) Can I add motorized latch retraction to a PDQ exit device that is already installed on the door?
Yes. The 639026 MLR kit is a factory conversion kit, meant to be added to an installed PDQ 6300 or 6400 Series device so you keep the existing chassis, push bar and door prep. PDQ's parts range is built around that approach, with conversion kits for cylinder dogging and alarms alongside this one.
3) Will the 639026 kit work on a rim device, or only on vertical rod and mortise exit devices?
The PDQ 6300 and 6400 Series parts program that 639026 belongs to covers rim, surface vertical rod, concealed vertical rod and mortise configurations. Order it against your specific device model and configuration, since MLR retracts the latch at the chassis.
4) What is the difference between the PDQ MLR kit and a cylinder dogging conversion kit?
Two different ways to hold a latch retracted. MLR (part 639026) uses a motor, so the latch retracts on an electrical signal and can be tied to an access control system or a scheduled unlock. Cylinder dogging, offered as a separate PDQ conversion kit, is mechanical: a key dogs the push bar down by hand. PDQ also lists signal switches among its 6300/6400 parts if you need position or request status back from the device.
5) Is PDQ 639026 an aftermarket part or a genuine PDQ component?
Genuine PDQ, part number 639026, sold as a factory replacement and conversion part for the 6300 and 6400 Series. That matters on panic hardware, since substituting non-factory internals on a panic or fire rated device can void the device's listing.
