PDQ 649001V – Frequently Asked Questions

1) What exactly is the PDQ 649001-V part?
It's a head chassis for a surface vertical rod exit device, narrow stile version, sold as a genuine PDQ replacement part. The head chassis is the mechanism at the top of the device that drives the vertical rod up to the top latch, so this is what you order when the operating mechanism has failed rather than the rods, push bar or latches.
2) Is the PDQ 649001-V head chassis for panic or fire rated doors?
PDQ lists the 649001-V as suitable for panic or fire applications, so the same head chassis covers both on narrow stile surface vertical rod devices. On a fire door assembly, the device must have no dogging, so confirm the rest of the device is in its fire configuration when you reassemble.
3) My PDQ device won't latch at the top of the door anymore. Is the head chassis the part I need?
Possibly, but check the rod and latch first. On a surface vertical rod device the head chassis drives the top rod; if the chassis is worn or broken, the top latch stops retracting and the door drags or won't release. If the rod connector or the top latchbolt is the failure instead, PDQ sells those separately along with rods, strikes and shims within the 6300 and 6400 replacement range.
4) Can I add cylinder dogging or an alarm to an existing PDQ exit device instead of replacing it?
Yes. PDQ offers conversion kits for cylinder dogging and for alarm functions on installed 6300 and 6400 Series devices, so you can upgrade in place. Those are separate kits from the 649001-V head chassis, which is a mechanical replacement part and does not include dogging or alarm hardware. Keep in mind dogging is not permitted on a fire rated door.
5) Is a surface vertical rod device the right choice for a pair of doors without a mullion?
Yes, that's the usual reason to pick one. A surface vertical rod device latches at the head and at the threshold on each leaf, so a pair of doors is secured without a center mullion. A rim device, by contrast, latches into a strike on the frame or mullion and needs a mullion on a pair. The 649001-V is the narrow stile head chassis for the surface vertical rod configuration.
6) I manage a building with several PDQ exit devices. Will one 649001-V work across all of them?
Only on the narrow stile surface vertical rod units. Across a mixed fleet you'll likely have rim, surface vertical rod, concealed vertical rod and mortise configurations, and each takes its own head chassis. Walk the openings, note the series (6300 wide stile or 6400 narrow stile) and the device type on each, then order the matching chassis per opening rather than stocking one part for all.
