Why do alarms go off?

The fire arms will get switched off when it is very cold outside. If there is flow of wind very hard below the door, the electric box has to be switched off. The fire alarm was found to be detecting the changes in temperature than the smoke. When there is power cut, the alarms of the car will start going off. The car alarms will go off when they run out of battery. But low battery will produce a particular sound at regular intervals. An abrupt going off of alarm might not be a battery problem.

The smoke detectors are kept for saving the lives. The public safety council has given the statistics that the mortality rate of houses with the working smoke detectors was 12 in 1000 people. There was significant increase in the rate of deaths in houses which did not have working fire alarms. The smoke detectors have to be maintained consistently and they have to be checked once in a month to keep them in good condition.

Alarms have sensitive sensors which can detect smoke as well as dust particles. The alarms might go off if any dust has fallen into them from ceiling. Cleaning the alarm must make it work properly. If it still does not do, then it is understood that the alarm has to be replaced with a new one and the existing one is an old one.

Compressed air must be used to blow off all the dust. Soft and dry brush is used for cleaning the sensor while the water or liquids are not used for doing it. Some alarms were reported to go off when there is moisture in the air. The alarms might go off due to any power glitch that might exist in the house. The phrase go off” might mean that the alarms have started working. If the sensitivity of the alarms in the car was not adjusted, a small breeze can connect the alarm and make it go off.

The alarm switch which needs pressure on it to go off will be applied with pressure by the sharp wind and cats around stepping on that.
