Smoke detectors that sound when smoke is not present may suffer from an electrical problem. The smoke sensor may be at fault as well. Some sound if the battery is low and needs replacement.Continue Reading
Smoke detectors are essential safety devices, and they have saved many lives through the years. When they sound when smoke is not present, however, they can become a nuisance. While smoke detectors have robust electrical wiring, their wiring may short-circuit or otherwise break. On occasion, faulty wiring can cause the detector to sound in the absence of smoke.
Smoke detectors are sensitive, and they require only a small amount of smoke to trigger. Because of their sensitivity, smoke detector sensors might react to the movement of air, dust or other factors. Because smoke detectors contain highly radioactive elements, those with fault sensors may need to be replaced.
Smoke detectors may beep if their batteries are running low, but many people interpret this as the smoke detector malfunctioning. If the beeping is only occasional, replacing the battery is likely to fix the problem. However, owners may wish to check the smoke detector's manual first; occasional beeping can also be caused by a malfunction, and it may not work properly if there is a fire.Learn more about Government & Politics
Replace smoke detectors 10 years from the manufacture date, or if it is not responding properly during monthly tests. Press the red test button underneath smoke alarms to perform monthly testing.Full Answer >
To monitor your home, place a hidden camera integrated in a wall clock, power adapter, coat hooks or smoke detectors in an appropriate place. The room must be properly lit, or opt to use night-vision cameras. First test the camera’s field of view, and use sufficient storage memory.Full Answer >
The most common problem in smoke detectors is faulty batteries, which cause the detector to beep until a new batter is installed. In generally, experts recommend replacing faulty smoke detectors instead of attempting to repair them.Full Answer >
The two most common types of smoke detectors are ionization detectors and photoelectric detectors. Ionization smoke detectors sound when smoke blocks the flow of ions they generate. A photoelectric smoke detector goes off when smoke particles bounce light from its LED against its photocell.Full Answer >
