Photoelectric Smoke Detector
This type of smoke detector operates with the help of a photoelectric sensor and a light beam. Any smoke entering the light beam will scatter the light and direct it towards the sensor, which in turn sounds the alarm. A photoelectric smoke detector is best suitable for slow, smouldering fires.
Combination Smoke Alarms
Combination detectors make use of both the above technologies to detect fires.
Where should a smoke detector be installed in your home?
An accurately placed smoke detector can go a long way in alerting you in time and in turn saving a lot of lives. There are a few strategic places to place a smoke detector that can help in detecting fires even before they start.
The best position to install a smoke detector is a few inches below the ceiling on a wall, ideally twelve inches below. There is a misconception that the ceiling is the best place for a smoke detector because smoke rises to the top. Of course, the latter is true, smoke does rise to the top, but in homes especially, gases from burning couch or mattress foam are lighter than smoke and go to the top, pushing the actual smoke about twelve inches below. In these circumstances, there is a chance the alarm won’t go off. The ceiling may be an acceptable option, but the area below the ceiling is much better for a smoke alarm.
In the kitchen
A smoke detector in the kitchen is must because a fire is most likely to occur in the kitchen. However, this also means that a false smoke alarm may be raised because the kitchen is also a place where cooking smoke is common. To tackle this, one can place the smoke alarm away from the stove area or use a good chimney to pull out the cooking smoke.
Hallways are the best places to put in smoke detectors since a fire will be detected much before it reaches the actual rooms, giving the residents ample time to vacate the premises.
Smoke detectors should be mandatory in homes because they can be triggered much before the actual fire occurs. So get your home protected today.
