sprinkler fire system

An overview of fire sprinkler systems

Fire sprinkler systems are an integral part of keeping any building protected from the threat of fire. Just as it’s paramount that you install sprinklers throughout your premises, so too is it that you have a working understanding of how sprinkler systems work. For those that would like some light shedding on the fundamentals of sprinklers then just read on below.

How Effective Are Sprinklers?

The most common question by those considering fire sprinklers is whether they are as effective as they claim. According to the NFPA damage caused to property by fire was cut by as much as fifty to sixty percent with sprinklers installed.

The NFPA additionally outlines that there have been zero multi-casualty fires in homes with sprinkler systems installed. That is a pretty convincing reason to install sprinkler systems.

How do Sprinkler Systems Work?

There are different types of sprinkler systems available on the market today.

The Wet Pipe Sprinkler Systems are the most common type of sprinkler system. Holding water in the pipes behind the sprinkler head, these systems are proficient for use in the vast majority of buildings.

The Dry Pipe Sprinkler Systems hold pressurised gas and water out of the pipes until the head breaks open. The dry pipe sprinkler is especially useful in cold water environments, preventing water from becoming frozen if left alone for extended periods of time.

The Deluge Systems store water in pipes with the heads kept open at all times. Once the fire alarm is activated the deluge fire sprinkler systems will not cease until such time as they are manually closed. Most often they are found near high-rise windows, warehouse bay entryways, and any other environments where a fire may spread rapidly.

The Pre-Action Sprinkler Systems are a combination of wet and dry pipes. The water isn’t stored in a sprinkler system until the moment that a fire is identified. At the moment that a fire is detected water rushes to fill the sprinklers before the heads open. These types of sprinklers are subjected to accidental tampering and a threat of severe water damage.

I have used RAD for a couple of projects and found them to be good to deal with. They did a pair of 3 storey open plan houses and seven three and four story town houses. The sprinklers were to improve fire safety, allow more flexible space and comply with building regulations. The sprinklers were far more cost effective than the mist type systems and look very discrete when installed.

My requirement was a bit unusual for RAD in that I wanted a mist system in one room of a rented house. I had no drawings or technical back up. RAD were very helpful and repositioned the unit after the initial installation. Luckily with the help of Sonny, the engineer it all worked out very well.
