FAQ
Fire sprinkler systems have to be tested in accordance to N.F.P.A. #25 standard for the inspection, testing and maintenance of water based fire sprinkler systems by a licensed fire sprinkler contractor.
Most fire sprinkler systems have to be tested at least annually by a qualified and licensed fire sprinkler contractor to remain compliant with the Authority Having Jurisdiction (Fire Marshal) and your Insurance Carrier. Some fire sprinkler systems also require quarterly and semi-annual fire sprinkler inspections to be performed on a regular basis.
Fire sprinkler permits are required when modifying fire sprinkler heads in existing buildings. Nearly all local counties/cities in the Washington, DC metro area require licensed and insured fire sprinkler contractors to submit a plan with material cut sheets for review and approval. Once the plan is approved a permit fee is paid and the work can commence. After the fire sprinkler work has been completed the Authority Having Jurisdiction will inspect the work to ensure the work is per the fire sprinkler plan and N.F.P.A. #13 codes.

Fire sprinkler heads are activated by heat and not smoke. Most fire sprinkler heads will activate at a ceiling temperature between 155-165 degrees.
Wet fire sprinkler systems are installed in heated buildings or in areas where temperatures do not get cold enough to freeze the water in the fire sprinkler pipes. Dry systems are installed in areas subject to freezing such as parking garages, freezers, loading docks and attics.
Most fires are put out by one fire sprinkler head that is in the area of the fire. Since the fire sprinkler heads are activated by heat only the ones in the heated fire area will activate.
