O.K.... Every once in awhile I get these call backs
for Residential interconnected 120 V. battery back-up
Smoke Detectors. Its bad enough with Arc faults and
Ground Faults so I always try to include several
Manuals so the Customer and Builder are aware of Reset
buttons and what proper procedures need to be taken.
If I have 10 or 12 Interconnected Smoke Detectors and
"Phantom Nuisance" False Alarms...whats the best way to
find out which one is the offending Alarm ?
Sometimes these things will work correctly and then at
2 in the morning one will mysteriously trip ?

Is there quick way to narrow this down ? thanks
