Rhode Island Fire Protection Services

There are many quality companies that we use depending on what is engineered for your specific application after we have made the determination on what your needs are.

Commercial & Industrial Systems

We design our commercial systems to meet the requirements of your specific application. We can also work from your specifications and have our engineers design and implement a total system. Some of the commercial applications we do are:

Types of Systems

fire pump

How the typical system works
All areas of the building are covered by a grid of pipes with sprinkler heads attached at each necessary point. Water from the pipes is supplied either by the town main, or a tank depending on the application.

Each sprinkler head will open individually when heat reaches a certain point, this will spray water on the fire. The other head will remain closed. The only heads that open are the ones in rooms where the heat reaches a certain point. This is to limit damage to your dwelling, or commercial structure.

Heads are generally placed in the ceiling to give maximum coverage to put out the fire. At the point where the water supply for the system is located there is a shut off valve.

wet system

Wet Systems – A wet pipe system is permanently charged with water. Water discharges from the system the second the system calls for it. Most systems discharge about 20-25 GPM. For special applications systems can discharge as much as 100 GPM.

 

 

 

dry system

Dry System – A dry pipe system is more suitable for an area that may be subject to go below freezing. Dry pipe systems use compressed air and nitrogen under pressure. When the system calls for it air is released so that the water will flow through the pipework and reach the fire.

 

 

 

Deluge System – These systems are very similar to wet or dry pipe systems with 2 major differences. Standard sprinklers are used but they are all open. The activating elements are removed so when the valve is opened water will flow from all for the heads simultaneously and deluge the area with water. The deluge valve is normally closed. The valve is opened by the activation of a separate fire detection systems.

These systems are used where larger amounts of waters are needed quickly to control a fast burning fire. These systems can be electrical, pneumatical or hydraulical.

Alternate System – This system is charged with compressed air during the winter and water for the remainder of the year.

Tail End System – A Tail End Pipe System is where a small section of the Wet System is kept dry during the Winter months.

Pre-Action System – This is use to detect electrical fires. Its used in conjunction with a dry pipe system, which is water filled in advance of sprinkler operation. This is often used for computer rooms. In preaction systems the piping is pressurized with air or nitrogen, monitoring the air pressure provides a means of monitoring the system piping. Loss of pressure in this system would send off an alarm at the panel.
