Which brand is good for smoke alarm?
Fire researchers have found that if a fire produces tiny particles of smoke, the ion alarm will be called before the photoelectric alarm.There is little time between the two alarms, but such fires spread so fast that time is vital to saving lives.
Because the ion alarm is sensitive to small particles, it will react quickly in cooking.If you have encountered this kind of problem, can have the following options: 1) will alarm installed in the far away from the cooking place, then smoke particles reach the alarm will become much weaker, if you choose this method, you should find out the air flow direction.Otherwise, it doesn't work.
When another fire occurs, a large amount of smoke particles are produced. Then, the photoelectric alarm will alarm first than the ion alarm.But the alarms for the two alarms are relatively large, but such fires can spread more slowly.If you want to have both advantages of both, can smoke alarm installed in place requires two kinds of alarm installed, or installed combined device with two sensors.
The ion alarm senses faster for tiny smoke particles, while the photoelectric alarm senses faster smoke particles.When the fire occurs, many tiny particles of smoke in the air, and smoldering when the smoke particles in the air will be slightly larger than some.
