Just wondered if it would have been affected by the unusual heat upstairs ???

They are smoke alarms, not heat detectors, inside is a tiny chamber which reacts when any smoke or vapour is detected, some of those on sale a few years back had faulty lithium batterys in them.
Ring Accy Fire station & they will fit you a new one free of charge.
