I was at a house the other day checking out a problem. Whenever ther iron was plugged in the smoke detectors would beep. The beeping would start slowly then increase in frequency almost to the point that it seemed as though they were in alarm. Any thoughts?
My experience suggests that some smoke detectors are sensitive to EMI. I've seen two seperate incidences where restoration of power to a house would cause battery operated smoke detectors to activate. In one case they simply chirped, and in another they went into full alarm.
Is the iron old and possibly faulty, could be generating a lot more noise than it should be...?
Odd... The only thing I can think of, is at all smoke locations, check the connection. Make sure the interconnect lead and neutral lead of each device is not crossed at the connection point in the box.
Are the smokes on the same circuit as where the iron is being plugged in? Voltage drop at a bad connection, I'd assume, would cause the smokes to dip below operating voltage... I'd assume the "beep" was to alert that the smokes were "without" power... I had a night service call where a homeowner couldn't get one of the interconnected smokes to shut up! Nothing had happened to instagate its behavior.... I got there, disconnected it... still going!, yanked the battery,... now it's chirping... I left it outside while I did paperwork for the customer & installed a new smoke... 20mins later I go out & it's still chirping every 3-5 secs.... I ended up parking my van on it to shut it up! The customer swore her house had not been built upon any type of cemetary or Indian burial ground!
