Had some BRK 120v detectors in my house for 10yrs. Had two units that went
bad in that they would go into full alarm in the middle of the night. Since
detectors are rated for 10yrs I replaced all six with First Alert SA9120BCN.
Now my new problem is the detectors randomly sound at various times of the
day. Just one blast from single units. I've done some reading on line and
have found that this is not an alarm but sensitivity to electric company sub
station switching. Going to calll First Alert tomorrow but in short these
units need to come down, they are annoying and scaring my child.
What's a good replacement 120volt with dc backup? I want to again link them
all using existing 3 wire system. I was looking at the Kidde PI2000. This
is a pain in the you know what.
I have Kidde alarms. However I also get false alarms from time to
time. One night the alarm went off. Ran around looking for smoke and
fire. Zip nothing. I then looked for an indicator to see which alarm
when off. On one with the flashing led, I noticed a spider scurrying
It may be that all along your alarms were fine. Do you have high
humidity, dust, or bugs. These can cause false alarms. If the alarm is
seemingly random, and stops after a bit, I would say it may be bugs
These are new detectors that replaced units 10+ years old. They go into
"latching" mode which is not Alarm. The offending unit sounds once and led
begins blinking. First Alert customer service says its an electrical
problem but I never had the problem with the old units. I've read these new
units are sensitive to electic company substation switching which may
interrupt the power for a millisecond but its enough to Latch the unit.
I told them my young child is not all too happy, on the verge of being
frightened. I started a call history so they said they'll make good. I
need to report reoccurrence (great). Then call them back and see where to
go from there.
Also have BRK First Alert Model 7010B have 6 of them that are 3 years old.
Have had multiple false alarms over the years but now with a new child
the false alarms are unbearable, however infrequent they are. Last night
had to take one off the ceiling because it would not stop alarming. Now
its replacement time.
Any suggestions on which photo detector brand or models don't have false
