How do I tell which of several smoke alarms is chirping?
Listen for the chirp and use the alarm's test or hush identification feature; replace batteries or units as specified, keeping all alarms active.
Why this approach makes sense
Identify when the sound happens and isolate one possible source at a time. Pipe, motor and building noises can travel well beyond their point of origin.
Before you try it
Do not dismantle electrical or pressurised systems to diagnose an intermittent noise; record the pattern before seeking repairs.
