B744 cabin crew rest Smoke detector.
Can someone who knows the system please tell me how the smoke detector in the rear crew rest area is reset? it affects the Recirc fans and a reset allows for the fans to be put back on line. I have looked at the panel and there is no Reset button, it only has Test switches (two A and B switches and a light test switch). I assume that testing the individual circuits will achieve the reset but would like to be sure before I go ahead and try it.
The engineers on the routes I fly don't have a clue about the system and there is nothing in the various manuals. Frustrating.
