Sprinkler System.

Testing and maintenance of the fire protection systems are required to assure that system
operate properly. Testing requirements vary from quarterly, semi-annual and annual per local
fire department and insurance requirements.

Wet Fire Sprinkler System:

Wet fire Sprinkler system is the most common of all fire sprinkler systems. This system consists of water that is constantly maintained within the sprinkler piping. When a sprinkler activates this water is immediately discharged onto the fire.

Annual Testing and Certification:

Our technician will inspect sprinkler heads to assure proper type, indicate if replacements are needed, and check for proper coverage per NFPA code. In addition our technicians will check any out of code sprinkler heads, such as painted, damaged, and out-dated sprinkler heads.

Main test will be performed with static residual pressure, and then followed by a flush of main drain and inspectors test vale. Once completed, our clients and the fire department will receive a fire sprinkler inspection report per NFPA 25 requirements.

Dry Fire Sprinkler System:

Dry fire sprinkler systems provide automatic protection in spaces where freezing is possible. Typical dry fire system installations include unheated warehouses and attics, outside exposed loading docks and within commercial freezers. A dry fire sprinkler system is one in which pipes are filled with pressurized air, rather than water. The dry-pipe valve prevents water from entering the pipe until a fire causes one or more sprinklers to operate. When a fire occurs, the air escape, the dry pipe valve releases, and then water enters the pipe, flowing through open sprinklers onto the fire.

Annual Testing and Certification:

Annual Testing of Antifreeze Loop

Our technician will take a small sample from multiple locations on the system piping and test the specific gravity of the solution to determine the effective freeze and burst points. Existing NFPA13D systems (systems installed before September 30, 2012) must be tested annually by a qualified individual. NFPA 13D provides two alternative test procedures. In the first alternative, the system is drained and two solution samples are taken, one near the beginning and one near the end of the draining process. In the second alternative, the system is not drained and two solution samples are taken, one at the highest practical elevation and one at the lowest practical elevation of the system.

Following the annual test, a tag must be attached to the riser indicating the date of the last test,  he type and concentration of antifreeze solution, the date the antifreeze was replaced (if applicable), a statement indicating if the entire system was drained and replaced with antifreeze and a notice to test the concentration of the solution at yearly intervals per NFPA 13D.

5 Year Internal Investigation

Our technician will disconnect the piping at various locations of the system piping, conduct a visual inspection and check for corrosion and debris. Upon completion, a Certificate will be sent to you. This service meets NFPA 25 requirements for 5 year obstruction investigation.
