Fires start small but in less than 30 seconds can turn into a major fire. In just two minutes, thick black smoke can fill a house making it life threatening and by five minutes the whole house can be engulfed in flames. Temperatures within a room can be 100 degrees Celsius at floor level and rise to 600 Celsius at eye level. Inhaling this super-hot air will scorch your lungs and melt clothes to your skin.
A residential fire sprinkler system consists of individually heat-activated heads connected to a network of pipes. Each head contains a heat element (a fluid filled glass bulb) that breaks at a prescribed temperature (approximately 70 Celsius), and triggers that individual head to release water. These heat elements are not affected by smoke, but heat only. Since each head is triggered individually by the heat from a fire below it, only the sprinkler head nearest the fire will activate – if it’s not sufficient to control the fire, the next nearest head will activate, and so on. In over 95% of cases, only one sprinkler operates and it is enough to control or extinguish the fire.
A fully automated sprinkler system can therefore tackle a fire at a very early stage, even if no one is around, releasing water directly over the source of the fire.
