Smoke alarms are essential components that help detect the presence of fire. However, they must be maintained and in good working condition to function correctly. This means changing the batteries, cleaning the system, and replacing them if faulty.
But when should you replace the smoke alarms? Generally, smoke alarms have a lifespan of about ten years, after which they should be replaced with new ones. This is because once they exhaust their lifespan, they lose sensitivity and may fail to trigger in case of a fire. However, other signs indicate you should replace your alarms even if they’re below ten years old. These signs include the following:
Since all smoke alarms have test buttons, experts suggest you test them monthly to determine their functionality. Testing your smoke alarms is easy; you only need to press the ‘test’ button to ensure it’s in good condition. If the system is perfect, it should beep several times. However, if it doesn’t or produces a weird sound, it’s faulty and must be replaced.
If you need to replace your smoke alarms but are unsure how to replace them, make sure that you contact reputable service providers in your area. For example, experts like Sarros Electrical are electricians in Australia that have some great principles to consider when deciding how many smoke alarms you need for your home.
If your smoke alarms start experiencing short chirps more often, you shouldn’t ignore them. The chirps usually indicate a low battery, but if you replace the battery and the chirping continues, it’s a sign to replace the unit. The persistent chirping means that your system is worn out, and if you ignore this issue, you’re putting your home at risk. Therefore, if you experience any form of chirping, consider contacting experts to schedule a replacement.
Smoke Alarm Start Turning Yellow
Many theories surround your smoke alarms turning yellow. Firstly, electricians say this sign signifies an aging smoke alarm. Secondly, some people believe that smoke alarms change color because of exposure to dust and cigarette smoke.
Although these may be true, experts have a different explanation about smoke alarms turning yellow. Smoke detectors contain a flame-retardant agent called bromine, which helps them withstand heat and smoke. When bromine is exposed to heat or oxygen, it causes the smoke alarms to turn yellow. This process takes a long to actualize, giving you time to plan for a replacement.
Recalled By Manufacturers
Manufacturers can recall smoke alarms if they are found to be defective or not functioning properly. In fact, there have been several instances of smoke alarm recalls in the past.
One example is the Kidde dual-sensor smoke alarms that were recalled in March 2018 due to a manufacturing defect that could prevent the alarms from detecting smoke. The recall affected over 450,000 units sold in the US and Canada.
When a smoke alarm is recalled, the manufacturer will typically issue a public notice and provide instructions for consumers on how to receive a replacement unit. In most cases, the manufacturer will offer a free replacement or repair of the affected units.
If you have a smoke alarm that has been recalled, it’s important to take immediate action to ensure the safety of your home against a fire outbreak. You should follow the manufacturer’s instructions for receiving a replacement unit, and you may also want to check with your local fire department for additional guidance on fire safety.
Goes Off Unexpectedly
Another obvious sign that your smoke detectors need replacement is when they go off more frequently and unexpectedly. You want your smoke alarms to be sensitive and functional enough to detect any smoke but not go off unexpectedly in the absence of smoke.
When smoke alarms age, they begin detecting issues that aren’t there. When this occurs, the smoke alarms go off more frequently, causing tension among home dwellers. When this happens more than once, the best option is to replace them to prevent them from going off, for example, every time the wind blows by them. This ensures that your alarms only go off when there’s a real threat.
If your smoke alarms are chirping persistently, goes off unexpectedly, start yellowing, or are recalled, it’s time to call in the professionals to replace your system. Smoke alarms should also be replaced if they’ve exhausted their lifespan.
The advantage of working with professionals is that they not only replace your alarms but also inspect your home and advise you on how many smoke alarms you need. Remember, smoke alarms are your first defense in case of a fire. If they fail to function correctly, your home might be at risk of fire breaking out without notice.
