    will a smoke alarms can go off with heat. According to my view a smoke alarms just go off with smoke. so please share with me if you have any experienced about it? But I must suggest to all of you that we all should maintain the smoke alarms and must change the battery after a short time.

    I am not aware of a smoke detector responding to heat, but I have one that can detect my popcorn pan on the stove even when no smoke is visible! And lately, it occasionally goes off in the middle of the night for no reason I can detect.

    They will alarm from Heat and Cold temperature.

    It is more of a Battery Voltage thing, than the electronics itself.

    When the Battery gets weak, then heat and cold can affect the battery voltage, and in turn strange may happen within the detector.

    I have seen this happen with the detectors in my attic.

    It is best to use a Aux powered detector, because the Batteries are a pain to change when in a remote location.

    Read the manufacturers manual. They all recommend to NOT install near an HVAC supply or return. This may be more a function of moving dust, etc. But expect some nuisance alarms.

    With the heat wave we have been having, one of my smoke alarms is driving me crazy! I have changed the battery 2 times and decided the reason for the beep, beep, beep, beep is due to the heat in the house. I do not have whole house air and this smoke alarm sits on the second floor and we all know, heat rises, eh. But, at least I know it is working.

    maybe changing the battery a 3rd time will fix it:p. Was it Einstein that said the definition of an idiot is doing things over and over the same way expecting it to turn out differently? Just making a joke Cookie, not calling you one. :)


    Try installing a new detector in that location and see if the new one falses out

    You better not be calling me one or no foil hat for you, quirky is okay, LOL.... Now, honestly, Bob... :) Now, I did switch around the smoke alarms, seriously, testing this out, and it beeps in that location. It is above a stairwell, between a set of bedrooms. Maybe, it is the humidity? It has been 96F for days on end, outside temp. It hit 100 a few times here. I am waiting to see when this heat wave breaks if the alarm in that location, will stop beeping. I'm telling ya, hot as hell here.

    Ahh, I did a quick search and found this. On this, #10 could very well apply since, it has been very hot and very humid, and the location of this smoke alarm is between 3 rooms, one is the bath. Humidity might be the problem right now.

    I cannot be the only person whom this is happening to right now with this weather. :)

    You are not the only one. I have played musical chairs also.

    Many Detectors Detect the Absence of Oxygen, so CO2 or anything including Humidity can screw them up.

    Even a Fart can false a good one if the wind is not blowing. It speaks the truth.

    Buy good Batteries tho. Anything 3 for $5 or less are cheap ones.

    Well, mine are pretty sensitive. They are the top of the line, and when the battery gets low it talks, and I am not so sure I like that in the middle of the night lol. Kind of spooky. :) And, being I have to climb waaay up there, and hang above a a stairwell, I make... sure... I buy the top of the line batteries so, it doesn't have to be done too frequently. Even, when I had a plumber in here, and he was using a torch on the flange setting off the alarm, he wouldn't climb up there, he was very kind, he told me to "take care of that alarm!" LOL. Good thing I am not afraid of height. The good news is, it is much cooler today, in the low 70's and it stopped beeping. Much more comfortable a day.

    A couple of days ago on CBS and ABC news they had a segment or a spot about the high humidity and smoke alarms. I don't know if anyone else caught it, but, it just basically said, about the high humidity some of the country has been experiencing has caused a flood of calls to places like Honeywell, etc, about smoke alarms going off and troubleshooting. So, there ya go.

    We have a smoke alarm in an area where three bedroom and one bath all join up, so it's the end of a hall with 4 doors. Every time one of the kids showers the steam from the open bathroom door will set off the smoke alarm...go figure.
