That would be difficult, the smoke detectors aren't numbered, so even knowing there were faulty ones in the batch, which was not discovered until years later, how could they identify where the faulty ones were. Yes they do keep record of who has been fitted with alarms, but to revisit all those would be impossible. They respond very quickly to reports of smoke alarm faults.
