Signs you see to know when to get a new Smoke Detector

Below are feasible signs you will see to let you know it’s time to throw an old smoke detector away and replace it with a new one. Check out the signs below to tell if smoke detector needs new battery or not :

Smoke Detector is Turning Yellow

Climbing up on a ladder to check the “manufacture date” on all the smoke detectors in your home seems like a tedious task. Old smoke detectors will begin to turn yellow over time especially when it’s over 10 years.

However, some people believe that smoke detectors turn yellow after spending many years being exposed to dust in the air. While others think they turn yellow due to accumulated cigarette smoke that comes in contact with them over and over again and causes them to become discolored.

The truth is that most smoke detectors contain bromine, which is used as a flame retardant. This makes the detector change its color to yellow. It is used to help the smoke detector stand up to a fire so that it can alert you if there’s smoke or fire anywhere around your home.

Bromine causes smoke detectors to turn yellow once it’s exposed to heat, oxygen, and Ultraviolet light. These reactions occur naturally inside a home over time. It takes a while for this process to materialize giving you a correct timeframe to order a replacement.

This is one of the most evident signs that you need to have a new smoke detector put into place immediately. You will be able to tell if smoke detector needs new battery or not.tell if Smoke Detector needs New Battery

Chirping Sound Almost all the time

The non-stop chirping sound that keeps coming from your smoke detector should not be overlooked. If you ignore the sound, you are eventually going tp 

If you don’t do something about the chirping, you’re eventually going to make your smoke detector non-functional. This could make you ignore a smoke detector that’s going off for real.

You will also be putting your home at risk since chirping could be a sign that a smoke detector battery is low and weak. Some smoke detectors chirp over and over (and over!) again when they are on their last legs.

You can stop the chirping sound by replacing the batteries in your smoke detector. However, in case you have fresh and new batteries in it or if you had it hardwired by an electrician and it’s still chirping, this should be a big cause for concern.

Plan to get a replacement for your smoke detector immediately to make the chirping sound a thing of the past. And you will also be able to tell if smoke detector needs new battery or nottell if Smoke Detector needs New Battery

It Doesn’t Respond Once You Test It

Always test your smoke detectors at least once every month or even more often than that. Testing a smoke detector is quite easy. All you need to do is tab the “test” button located on the smoke detector to ensure your smoke detector is working properly.

If your smoke detector is functioning optimally, then it should beep several times (ensure you take few steps back since these beeps are usually very loud!). This will notify you that you don’t have anything to be worried about.

However, in case your smoke detector isn’t working properly the way it should be, then, it won’t beep at all when you test it out. Or if it does beep, it will sound very faint and won’t have much of an impact on you.

Ensure you adhere to the USFA guidelines and test your smoke detector out at least once every month. You should also consider replacing your smoke detector once you don’t get a satisfactory reaction from it when you put it to the test.

About 60% of the deaths caused by fires every year in U.S. homes don’t have functional smoke detectors in them according to USFA reports. You can ensure that your home doesn’t become a part of this disturbing statistic by running a regular test on your smoke detectors.

It Suddenly goes off without Prior Notice 

As smoke detectors get older, although, it’s common for most of them to struggle with sensitivity issues. They suddenly begin to pick up on issues that don’t even exist.

When this occurs, some smoke detectors will start to go off all the time for no real reason. It can be very frustrating that some homeowners will take their smoke detectors down and remove the batteries from them to get them to be silent.

In case you have smoke detectors like this in your home, it’s best to replace them than to continuously remove their batteries from them. You will be putting your home at risk of fires every time you take a smoke detector down completely and disconnect it.

You certainly don’t want your smoke detectors to go off after picking up on the presence of a few specks of dust. However, you might want them to be sensitive enough to detect real smoke from a fire if you ever experience one in your home.

The only way to guarantee if they will be able to do this is by replacing them when they get old immediately. This will ensure that they only go off when you need them to. That’s it!

It Contains Faulty Parts That Led to a Recall

Always check your smoke detector to see if a recall has been done in your home. Although this is time-consuming and a bit tedious it is sure worth it.

Some smoke detectors are occasionally recalled due to faulty parts found inside of them. You might be lucky and spot a story about your smoke detectors being recalled on the news. However, unless your smoke detector is part of a huge recall, you can’t always count on the news to let you know about a recall.

You can also make use of the internet to see if you can find any information regarding a recall on your home’s smoke detectors. Check again in the months and years to come too, since there is always a chance your smoke detectors could be recalled at a later date.
