You may have noticed that your smoke detector blinking red no sound. No need to be panic-y. There is nothing wrong with your device, really. It doesn’t mean that you are facing a fire hazard, either.
Depending on the model and make of the device, the blinking red light can mean many things, but what about the no sound situation? And how does the red light refer to different situations or conditions?
Time Intervals and Blinking Red Light
Pay attention to the time interval because it may point you to the proper situation.
- If the detector blinks for 5 to 8 seconds, it’s running out of battery. The juice is low, so you need to replace it.
- If it blinks for 10 seconds, there is a possibility that you have internal malfunction of the device.
- If it blinks for 15 seconds, the detector seriously needs battery replacement.
- If it blinks for 30 seconds, even up to a minute (60 seconds), your detector works perfectly.
Should a Red Light Be on the Smoke Detector?
It depends on the situation. If the light is red and it’s on occasionally, there are some possible causes and scenarios. But if the smoke detector flashes red light continuously without stopping, you should know it.
Why Is My Smoke Detector Not Making a Sound?
There are several possible reasons why the smoke detector is blinking red with no sound.
- Dust. The device has sensors to detect gas, flame, and heat in the air. Over time, the device may accumulate dust and dirt. As a result, the sensors won’t be able to function well. Sometimes, you may see the blinking red light but without any sound. But in other cases, it’s possible that you don’t even see the red light.
- Lack of power. If you have the detector for quite some time, it’s quite common if it doesn’t get enough power as before. There is also a possibility of electrical faults, such as loose wiring. It’s better to have a technician check your detector to be sure.
- Replacement requirement. If your detector is old enough, it may be time for you to replace it. It’s also possible that you need to upgrade the detector. In general, smoke detectors will work well for up to 10 years. If it’s more than that, you must replace it.
When the detector is low on (battery) power, some detectors will make a chirping sound rather than a beeping sound. Most batteries only last for around 6 months, so you need to check the batteries regularly.
But if your detector runs on li-ion power, you won’t have to change any battery. But if you have the blinking red light, it’s probably the wires’ loose connection.
If the detector blinks for 10 seconds, there are some possible options, but it depends on the model and type. It can be an internal malfunction, faulty internal components, or faulty wirings. Checking your device is always a good idea if you’re in doubt.
Don’t be alarmed if your detector blinks once in 30 to 60 seconds. It means that it’s completely normal. The alert system on your detector has been activated, so it’s ready to work properly. If you want to be sure, consult your manual.
In an overall sense, you have the manual where you can do the checking. It’s also advisable to ask for help from a professional technician if you aren’t sure. It’s always better to be cautious rather than sorry, especially if you are dealing with smoke detector blinking red no sound.
