How to temporarily silence your alarms:DO NOT USE THIS FEATURE IF A FIRE IS PRESENT. ONLY USE THIS FEATURE AFTER YOU HAVE CONFIRMED THERE IS NO DANGER. Show
The Hush® feature of most alarms provides the capability to temporarily lower the sensitivity of the smoke sensor for up to 10 minutes. This feature should be used only when a known alarm condition, such as smoke or heat from cooking, activates the alarm.
How to clean and reset your alarms:If you have hardwired alarms, the first step is finding the initiating unit, as that is the key to stopping all of the interconnected units from sounding:
See examples below: The arrows are showing the areas to clean using compressed air on an ionization alarm. Shown here is an i12060. The arrows are showing the areas to clean using compressed air on a photoelectric alarm. Shown here is a P3010.

Back to Support CenterThe shrill beeping of a fire alarm when you’re cooking or in the middle of the night is definitely irritating. While the purpose of smoke alarms is to alert you of danger, sometimes they go off when there’s no fire. And there are few noises quite as loud and disruptive in your home than a beeping fire alarm with no apparent cause. If your fire alarm keeps going off, we’ll cover how these smoke alarms work, some of the most common reasons why they might go off, and how to adjust them correctly. How Do Smoke Alarms Work?Understanding how smoke alarms work can help with understanding why they might be going off. Two types of alarms use two different ways of detecting smoke: photoelectric and ionization. Photoelectric smoke alarms use a beam of light in their internal chamber to detect smoke. When particles get into the chamber and fracture the beam of light, the alarm goes off. An ionization smoke detector also has a chamber inside, but this chamber has ions and electrons whizzing around inside. When smoke gets inside, the smoke particles attach to the ions, which changes the chemical structure and triggers the alarm. Smoke particles aren’t the only things that can disrupt the photoelectric light beam or attach to the ions, and that’s why fire alarms can sometimes go off without an apparent fire. Causes of Smoke Alarms Going OffEssentially, what makes your fire alarms keep going off is something disrupting the chamber inside of it. But there are a variety of factors that might do that. These are some of the most common reasons why your smoke detectors might be going off: PlacementSmoke detectors should be in every bedroom, in hallways, near fireplaces, near the kitchen, and stairways. But where you put the smoke detectors in these locations could be the problem with your false alarms. Is your smoke detector over a stove? Is it right next to a bathroom where steam from a shower might set it off? Is it above a toaster? Is it directly next to a window or door where outside elements might set it off? All of these questions are worth considering when you’re looking for causes of a fire alert. Burned FoodBurned food creates smoke, and if that smoke ends up near a smoke alarm, it’ll go off. If your smoke detector is less than ten feet away from the appliances, you could use a fan or install a vent to help suck out some of that excess smoke. If the alarm is far enough away, you might want to look at your smoke detector’s sensitivity. Steam & HumiditySteam from your home and humidity from outside work similarly to burned food. You’ll want to check if your alarms are too close to a window, door, or steamy bathroom and see if that’s the source of your false alarms. You can try using fans during showers or next to windows to dissipate the steam and humidity as well. But your alarms might not be too close and still go off whenever the bathroom gets steamy. That, again, might be a problem with the sensitivity. InsectsIt’s disgusting but true: insects can get trapped in the chambers inside of a smoke detector. These bugs can then set off your smoke alarm for no apparent reason. It’s worth taking a look inside your smoke detector to see if a pesky insect might be causing your false alarms. DustThe same little holes that might let a bug in can also let in dust. Over time, this dust can build up and disrupt the sensors inside of the alarm and set it off. It’s worth cleaning out your smoke detectors if they’re going off. But to make sure a dust build-up isn’t the cause, you should try to clean out your smoke detectors at least once a year. A vacuum brush attachment is an easy way to clean it out. ChemicalsProximity to strong chemicals can also make your smoke alarm go off. If you store your cleaning supplies right by a smoke alarm, that might be the problem. Or if you’re remodeling your home or painting, that could also be the source of your false alarms. BatteriesThe average smoke alarm battery needs to be changed every six months. Many people change them each Daylight Savings day to help remember. If your smoke alarm needs new batteries, it will chirp and beep for a prolonged period or repeatedly. To avoid having to worry about changing the smoke detector batteries, there are smoke detectors that run for ten years without needing a switch. MalfunctionMalfunctions with a smoke detector don’t happen very often, but they can happen. If there seems to be no other cause for the alarm, you might have a smoke detector malfunction. A malfunction signals that it’s time for a new fire alarm. End of LifeWhen smoke detectors reach the end of their life, they’ll beep and let you know. Sometimes the cause of the false alarms is that it’s time to get your fire alarms replaced. Adjusting Your Smoke DetectorIf you’re having trouble with your smoke detectors, these are some of the most common ways to adjust them:

The best smoke detectors provide top-tier protection and control. Here at SafeStreets, we provide high-quality smoke detectors to help keep your family and home safe. Our detectors can detect even the smallest fires, and ADT monitoring professionals will dispatch help your home when they go off. We take fire safety seriously. Check out our fire and life safety products or call us for a free quote to get started finding the right smoke detectors. Why would a smoke alarm go off for no reason?The most likely reason smoke detectors go off unexpectedly is that people aren't changing the batteries in them often enough. In most sensors you might think of, the strength of the signal goes up when they detect what they're supposed to.
Why did my fire alarm randomly go off in the middle of the night?This battery characteristic can cause a smoke alarm to enter the low battery chirp mode when air temperatures drop. Most homes are the coolest between 2 a.m. and 6 a.m. That's why the alarm may sound a low-battery chirp in the middle of the night, and then stop when the home warms up a few degrees.
How do you silence a fire alarm?The smoke alarm is desensitized by pushing the “Test/Hush” button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately.
