Hi, Tim,

Thank you to you and everyone else for your answers and guidance.

I have no idea if my 3 detectors are wired together. When the one in
the kitchen sounds (if I broil, it always does), I have no idea if the
others are also sounding. Is there any way to tell this? Over the
years, we have found many areas where the builder and his workers cut
corners. I would not be surprised if this is yet another of those
areas.

Hello Myrna,

All 3 should be replaced bacause of their age. As with all electronic
devices, smoke alarms degrade over time, and the failure rate increases
over time. Most manufacturers indicate that smoke alarms should be
replaced every ten years.



Best regards,

Tim
