carbon monoxide detector reads 7 image
OWL
Every about five minutes a loud quick beep hurt my ears,I think I once heard that it might be the fire alarms low on battery can it be this? I heard it in many other houses too.like my Grampa's House and friend's houses.What can this be?It's driving me NUTS!

READ EVERY WORD FIRST, ALL OF THEM, PLEASE!!!!
Well that's an easy one, I am assuming you are young since you reference Grandpa. Note the beep has to be from something electronic Possible sources: Burglar Alarm company backup battery to the main system is weak, the remotely located wireless window/door sensors have batteries that when dead make the Alarm console beep.
A smoke detector is likely. I have some that mount directly to the wall and some to a bracket that is mounted and you turn the "front" of the detector CCW or CW to remove from the bracket. You need to know if the smoke/fire alarm is a battery unit (CLUE: IF YOU CAN TAKE IT OFF WHERE ITS MOUNTED AND IF IT HAS NO WIRE INTO THE WALL/CEILING ITS BATTERY, NOW TURN IT OVER TO THE "WALL SIDE", MAYBE THERE IS A VISIBLE 9V BATTERY COMPARMENT SPOT RIGHT IN FRONT OF YOU), if not it might be a open the cover unit, so, open the cover by looking, AND THEN LOOKING AGAIN, you might have to pry a "tab" or unscrew a screw before opening, when you see the 9v battery you will be half done, (if YOU DON'T ABSOLUTELY KNOW WHAT A 9V BATTERY LOOKS LIKE STOP SEE TEST BUTTON BELOW). PLEASE don't mess with the "120" volt smoke detector, call the company if it's the "beeper" [all non battery smoke detectors may not be "120" volt but they may be 12-24 volt AC or DC so they still might be dangerous] (I say that more for those who might nitpick me).
If it really beeps every five minutes it wont hurt to pull the 9volt battery and wait 7 minutes. TEST SECTION: If you can't wait, be brave, re-read above and extract the battery, put the 9v battery to your tongue, if it mildly tingles it's a dead battery, if it smarts put it back in and wait the "5" minutes. NOTE YOU CAN'T DIE FROM THIS EXCEPT MAYBE IF YOU HAVE A PACEMAKER OR BUILT-IN HEART DEFIBRILLATOR SO THOSE FOLKS DON'T "TONGUE" IT.
Or best of all, get a volt meter from an electronics pal. 9 volts minus 1.8=7.2 volts = battery no good (if the battery is low by 20% its dead, this even applies with 6 volt, 1.5volt etc.( -20% is my guide for alkaline batteries),
Also if you are afraid just press the TEST BUTTON, on the smoke detector, if it has one, buy a new one if it doesn't have a test button, its too old or the owner was too frugal. [IF IT WONT SOUND OFF UNDER TEST ITS DEAD, IF IT DOES SOUND THEN YOU CAN NOW KNOW IF ITS "YOUR BEEP"] Now identify if its a 9v battery by taking it gently off its mount or bracket mount also see above again. See the test section if you feel braver.
If you succeed in removal AND REPLACE THE 9V note that I put all my detectors on a wall AS CLOSE to the ceiling on a 3-4 inch bread twist tie or better "wire" to a screw or thumb tack [ yes it looks fine if you do it right] for easy removal of batteries and no loss of sensitivity. Generally smoke rises driven by the heat, so the closer to the ceiling the better.
(this wire mount idea is at your discretion, I'm sure some fire guy is gonna disagree but in my experience of an actual house fire in 1987 with the detectors mounted as such, they saved my sleeping wife and cat!)
Check for a carbon monoxide detector and again make sure its not "120" volt, press the test button. A UPS on your computer with a near dead battery makes beeps. A medical device for "Gramps" may be at fault. a cell phone or cordless home phone beeps when near dead. A microwave or new fridge with the door open can beep. An AC alarm clock can beep when its 9volt battery gets weak.. Get the common thread?
If after all that you can't isolate it, invite some other young folks over for sodas, [statistically better at hearing high pitched beeps] put the battery back in the smoke detector and have the young'uns stand at different parts around the seeming sound area to pinpoint the beep. Keep in mind that some beeps are so foxy that they are like a ventriloquist and "throw their voices" so move around like musical chairs till every one agrees. Need I say more?? Good Luck! WHEW

Carbon Monoxide Detector went crazy this morning?
Mynameis
I have a new Kidde NightHawke Carbon Monoxide detector. We got it about a month ago and it has worked just fine. I live in Ohio and we are in the midst of a winter storm so we have had 5-7 inches of snow and the temp is around 5 right now. This morning as I was leaving I glanced at the CM detector as I always do and it was rising from 30 to 33 to 36. Now normally it sits at zero. I woke my husband and let him know as I left and called our furnace tech. It never went higher than 36 and eventually went back down to 0. We have gas heat, water tank is gas. Nothing else is gas in the house. We were running an a small electrical heater in the laundry room to keep the pipes from freezing, could that have caused this? What else would cause this?
The reason this concerns me so much is we have a 19 month old.
Answer
That is Dangerous.
I would keep an eye on it. If the detector is near a furnace vent I would check the detector when the furnace first comes on. Sometimes with a cracked heat exchanger it will build up some CO when heating before the blower fan comes on. That will give a rise on the reading at the start and then it goes back down as the air mixes in the house.
If you get more readings on the detector, you definitely need the furnace and water heater checked.
