Looking at fire sprinkler design can be fascinating. These systems can help protect property, save lives, and suppress fire damage in all kinds of settings. Whether in a home or in a business, fire sprinkler systems are truly amazing safety tools. But have you ever wondered how a fire sprinkler system knows that there’s a fire? Let’s take a closer look at how fire sprinkler systems work.
Most people think that a fire sprinkler system turns on because there’s smoke, but the reality is a little bit different. The truth is that fire sprinkler systems are triggered by heat, not smoke. Most fire sprinkler systems have a small glass tube near the sprinkler head that ordinarily keeps the head closed off. When it gets hot enough, that glass tube breaks and the sprinkler starts spraying water.
Fire sprinkler systems also don’t go off all at once. Rather, the sprinkler heads that are closest to the fire — the ones that experience the most heat — will activate first. As a fire spreads, more sprinkler heads will begin to activate. This helps prevent excess property damage.
