little tiny spiders crawl in mine sometimes. But twice within a day or
two? probably not likely.

Smoke from candle or incense?

Fumes from air fresheners or other chemicals (hair/body spray...)?

Dust from air vent?

Steam from the shower?

According to a neighbor, their one hardwired alarm, on the ceilling of
the second floor hall, was falsing so they took it out to get it
repaired or replaced.

While it was out, the analog clock in the stove, on the first place,
set fire to the kitchen.

This story was 2 to 4 months from start to finish. I'ts hard to
imagine it going on for 4 years.

P&M

happening that should set it off. I was thinking of tracing the
existing wire, i guess it runs to the next

the wire seems an even less likely culprit. If the wire were at fault,
removing the bedroom detector would still leave the others falsing.
