Every year, fires kill or even injure thousands of people majority of them in their homes. Fire sprinklers have been saving lives for more than a century, with reduced costs fire sprinklers have also been used in homes. Fire sprinklers provide the ultimate fire protection and an important feature in today’s homes.

They can control or even extinguish fires quickly, restricting the spread of toxic smoke and deadly heat. Which saves lives, protects property and other family valuables. If you’re marketing a house with fire sprinklers, you have a good selling point.

What better selling point would you offer than a house built with a firefighter on duty 24/7?

the cold-water plumbing lines in the house, so the sprinklers perform just like any other plumbing fixture. These systems were created specifically for residential use, and are designed to be easily and seamlessly incorporated into a home’s construction process.

Standalone residential sprinkler systems use a separate, additional system of piping that must be kept isolated from the home’s drinking water supply by a backflow preventer. This component adds additional cost to the initial installation as well as annual maintenance costs which can significantly add up over time.

4 Types of Fire Sprinkler Systems

This is the most common type of sprinkler system, which is also used in office buildings, retail establishments and climate-controlled warehouses. The name speaks for itself; the wet system constantly has water running in the sprinkler piping. Most of the workplaces use this because of its fast reaction time.

It works through enabling a heat-detecting glass bulb on the sprinkler head to break instantly once fire is detected. Though efficient, these systems are only recommended in areas with a steady temperature above freezing level to prevent water from solidifying. As a result of disregarding caution, some buildings have resulted to leaking pipes due to the freezing and expanding of water.

Dry systems  

Opposite the wet system is the dry pipe system for unheated buildings with a freezing environment. The dry pipe system works by holding in pressurised air throughout the system. When fire breaks out, the heat-detecting glass bulb bursts and releases all pressurised air before the water passes through. It is best to install these fire sprinklers in concealed spaces to prevent outdoor temperatures from controlling the water temperature stored.

Pre-action systems

These are a combination of wet, dry and deluge systems. Used for places with valuable and highly protected materials, this system works especially for preventing accidental activation. In this case, a double interlock system is integrated for a simultaneous activation of the fire detector by opening the pre-action valve, allowing the water to flow into the piping system.

Activating the sprinkler will disperse water all throughout the sprinkler systems just as the deluge system works. Both detector and sprinkler work simultaneously for the activation of the protected area.  In its dormancy, the piping system is filled with air similar to the dry system.   

Deluge systems

Hazardous places usually have this type of system. Using open sprinkler heads, all the sprinklers in the system discharges water immediately flooding the flaming hazard. The deluge system is necessary for areas where potential flammable chemicals and substances can cause rapid spread of fire.
