Commercial and residential fire sprinkler systems and other fire suppression systems have one goal: extinguish the fire to be able to prevent and minimize property loss and lifestyles.
Different varieties of fire sprinkler systems
There are approximately 6 different varieties of fire sprinkler systems utilized throughout the U.S., wet pipe, dry pipe, deluge and pre-action, foam water, and “water spray systems”. The two most commonly installed sprinkler systems in commercial environments and businesses are wet pipe systems and dry pipe systems.
Wet pipe sprinkler systems
Wet pipe sprinkler systems are the most popular type to have installed for a number of reasons. These systems are the easiest in function and therefore the most reliable. As expected, when the temperature of an area reaches a pre-set level, the glass bulb or link found in the affected irrigation head releases permitting the flow of water. The cost of a wet pipe system is also generally the most inexpensive to have installed and maintain.

The atmosphere filling the line is expelled, then replaced with the water supply pushing in behind. The intended purpose of a dry pipe system is to allow for freezing temperatures and greatly lowering the possibility of a freezing water line causing a rupture. A system such as this type can be less effective initially in extinguishing a fire on account of the delay of water reaching the sprinkler head and dousing the fire.
Deluge systems are common in which the risk of fire spreading quickly is an issue. Deluge sprinkler systems, when activated simply spray water from every sprinkler head simultaneously rather than individual sprinkler head activation.
Foam water and “water spray” systems
Foam water and “water spray” systems are usually installed where potentially hazardous substances are located and sensitive equipment. A combination of foam and water helps to curb the fire while the latter system sprays water in a particular spray pattern. These last two systems are not necessary for nearly all commercial businesses. Having any of these fire sprinkler installments isn’t enough.
Proper maintenance, as with any machinery, is crucial for successful operation. Depending upon the individual state or even local city legislation, fire sprinkler systems must be inspected at least once per year, often more often. In order for discounts on insurance, insurance companies will sometimes require proof of review.
