Corbin Russwin 704F479 – Frequently Asked Questions

1) Will the Corbin Russwin 704F479 PC board work on my ED4000 exit device?
Yes. The 704F479 delayed egress PC board is built for Corbin Russwin ED4000 and ED5000 Series exit devices, in the SA 36 inch BOCA configuration. If your device is one of those two series and is a delayed egress model, this is the board that runs the timed release function. It will not do anything on a non-delayed-egress device, since there is no delay circuit in those to replace.
2) What delay times can I order the 704F479 delayed egress board in?
Two delay settings are offered, 15 and 30. Pick the one that matches what the opening is supposed to hold for before release, because the board you order determines it. Facilities standardizing across several openings should order the same delay value on each so the doors behave identically.
3) My delayed egress exit device stopped releasing on time. Do I need to replace the whole device?
Not necessarily. The delay timing on Corbin Russwin ED4000 and ED5000 delayed egress devices is governed by the PC board, and the 704F479 is that board sold on its own. Swapping the board restores the timed-release control without pulling and re-prepping the whole exit device, which is the usual route for maintenance teams keeping an opening in service.
4) Is the 704F479 a genuine Corbin Russwin part or an aftermarket board?
It is an OEM Corbin Russwin component, not a third-party equivalent. For a delayed egress opening that has to release on a defined timing, that matters: the board is the electronic heart of the function, and an OEM part keeps the device operating the way the original assembly was specified.
5) I have an ED5000 rim device without the SA 36 inch BOCA setup. Is the 704F479 still the right board?
The 704F479 is specified for the SA 36 inch BOCA configuration on ED4000 and ED5000 devices. Delayed egress boards in these series are configuration-specific, so check the configuration stamped on your existing device or board before ordering. If it is a different configuration, you need the board matched to that one rather than this part number.
6) Is this delayed egress board suitable for a commercial building or is it a residential part?
Strictly commercial. The 704F479 is a commercial-grade exit device part, and it turns up in offices, healthcare facilities, schools, retail, government buildings, warehouses and multi-tenant residential properties running commercial exit hardware. Anywhere an ED4000 or ED5000 delayed egress device is installed, this is the service part for the electronics.
