Automatic fire sprinklers are individually heat-activated and tied into a network of piping with water under pressure. When the heat of a fire raises the sprinkler temperature to its operating point (usually 165 degrees) a solder link will melt or a liquid-filled glass bulb will shatter to open that single sprinkler, releasing water directly over the source of the heat.

Fire sprinklers do require regular attention to maintain readiness for fire protection. The following tips should be followed to maintain your fire sprinklers.   

• Schedule regular quarterly or annual inspections of your fire sprinklers
• Never paint your fire sprinklers.
• Never hang anything from your fire sprinklers.
• Never stack items close to your fire sprinklers. Shelving and/or furniture needs to be at least 18 inches below fire sprinklers.
• Always report any fire sprinkler damage immediately to a licensed fire protection company.
• Always maintain control valves in the open position.

Residential fire sprinklers are smaller and lower-profiled than the types of sprinklers that are used in commercial properties. Each sprinkler has a temperature-sensitive element. When temperatures reach between 135-165 degrees, sprinklers will individually activate and control your fire until the fire department arrives. Residential fire sprinkler systems operate off the household water main or by a storage tank. The piping is hidden behind walls and ceilings.
