【 Weak current College 】 smoke feeling alarm apparatus false positives causes and solutions-Power By 【 China power house network 】

Key positives causes include the following: 1, cooking 2, when the pass on, the alarm will be going on 3, intermittently alarm 4, steam or moisture of 5, cigarette smoke 6, power supply is bad. Many cooking fumes of false positives is issued by ion detector. Because this kind of sensor on extremely small smoke particles less sensitive, even if it is visible to the naked eye cannot see the particles. The cooking temperature smoke particles is one of the naked eye cannot see. There are two basic solutions: either the location of a mobile alarm, either into another kind of cooking smoke alarm is not too sensitive. The alarm on the cooking at distant place makes cooking smoke when it reaches the alarm has become very thin, thus reducing false positives. But this method does not always work, especially when the air flow will smoke from cooking to the alarm time can produce false positives. So when you move the monitor to make sure the air flow direction. The second solution is to replace alarms, here are three choices. One is to buy a new ion with a mute button alarm. As long as a honk button alarm stops the alarm for 15 minutes, so you have enough time for cooking smoke diffusion. The second option is to buy a photoelectric smoke alarm. Install the battery by photoelectric detector costs less than $ 20. Photoelectric detectors on small smoke particles less sensitive, so cooking smoke particles does not generate false positives. Even if this will make the photoelectric alarms on fire (fires of tiny particles larger) response to slower, but the time difference is very small. The third option is to have two common device. sensors Ion sensors and photoelectric sensor combined use, manufacturers make ions on cooking smoke particles less sensitive. In this way, the owners have two common benefit, the sensor also reduces false positives. If the alarm constantly emits a beep sound, either alarm in accumulated too much dust or alarm time too long, or it may be something wrong with the alarm system. Alarm sensors if used too long will also become sensitive to smoke. In the not too much, the alarm will sound the alarm. All home alarm in spent ten years should be replaced. Maybe you bought the alarm was expensive, but even the new alarm may be defective. If a new alarm keeps a beep sound you should use a new alarm will be replaced. If there is no fire will intermittently alert is going on? if so, it may also be due to alarm using long becomes sensitive. Or is the inner product of too much dust, or it may be something wrong with the alarm system. But sometimes the battery starts to run low, when approximately every minute, can also be issued by the chirp of sound, some people will think this is a false positive. But the sound is very good distinction, because it is a single, short sounds, and approximately every minute, emits a sound like that. If your alarms are intermittently making such sound, you can replace the battery see if the problem cannot be solved. If not, then you should consider replacing the alarm or to clean up. Clean the alarm time, the end of the vacuum cleaner, close to all the little alarm port clean one by one. This product in alarm covering dust can be completely clear. If you are still unable to remove dust, only to be replaced. Steam or moisture may condense on the sensor and wiring board, if the concentration is too much water vapor would beep sound. The alarm system installed at a distance of vapour and moisture more distant areas such as bathroom in corridor should not alarm installation, so that you can solve the problem. However, if the alarm was working, but now on steam or moisture reacts, the problem may be the cause of the alarm system aging. Older alarm will become more sensitive and easier on the vapour and moisture response occurs. So the occurrence of false positives or alarm over age needs to be replaced. In General, the smoke alarm is not on the cigarette issue response unless the smoke a very strong, for example, many smokers are in the same room smoking may cause alarm, if from alarm device is very close to the blowing, it also happens the response, but not always the case, if the alarm is too old, even if the smoke concentration is low, it will respond. So instead, we can also do this to judge the alarm has been aging. Battery is bad, there is no practical way to repair, this may be due to the alarm system is too old or replace the battery, but it is also a replace alarm signal.
