Where is the cause of false alarm of smoke alarm

General household smoke alarm is independent of the use of battery powered, no wiring, so the alarm will not happen.
The kitchen is generally not install smoke alarms, because eating fried cooking smoke, water vapor is generated will lead to false alarm, will damage the performance of smoke, kitchen gas alarm is usually installed on it.
If the installation of smoke is wired, different manufacturers of products wiring method is not the same. If it has been the alarm, it may be the wrong line, and if it is later this problem, it is not the problem of the connection, the proposed manufacturers after sales call.
Other reasons for false alarms are:
Power: battery when running out about every minute will make the chirp sound (different models in the interval and the sound will be different, but there is lack of electricity, there are early warning function) will think this is a false alarm. But the sound is very good distinction, because it is a single, short sound, and about every minute will make a sound like this.
Solution: if your alarm is intermittent to make this sound, you can replace the battery to see if the problem can be solved.
Cigarette smoke. Under normal circumstances, the smoke alarm is not to respond to the cigarette smoke, unless the smoke is very strong, for example, many smokers are in the same room smoking may cause alarm. If the alarm is too old, even if the concentration of the smoke is very low, it will respond to the. So on the contrary, we can also judge whether the alarm has been aging.
Solution: replace the alarm
Dust: if the alarm continues to issue a warning sound, then it may be an alarm in the accumulation of too much dust.
Solution: the replacement of the alarm or to consider the cleaning of the. When cleaning the alarm, the end of the vacuum cleaner is close to the opening of the alarm to be cleaned one by one. In this way, the dust of the alarm can be completely removed.
Steam or moisture: steam or moisture will condense on the sensor and the circuit board. If too much water vapor is condensed, the alarm will be issued.
Solution: the alarm device is installed in the steam and moisture away from the place, such as the bathroom corridor should not be installed alarm, so you can solve the problem. However, if the alarm would normally work, but now the vapor or moisture from the reaction, then the problem may be the cause of the alarm alarm. Older alarms will become more sensitive and more likely to respond to vapor and moisture. So the occurrence of false alarm may also be more than the use of the alarm device needs to be replaced.
