Sprinkler Maintenance

So how do they work?

Each sprinkler head is a heat sensitive device and works independently of the other sprinkler heads. The typical residential sprinkler activates at a sustained temperature of 155° Fahrenheit and the activation time, or RTI, is approximately 10 seconds. A sprinkler's main components are a frame, stationary deflector, glass bulb or fusible link and a seat. Upon activation, either the bulb ruptures or the link fuses, the seat will release and water will flow from the orifice above the seat to the deflector and water is distributed in the room.

The sprinklers are supplied by a network of piping that is concealed above the ceiling, in the walls, and below the floor, or a combination of all three. This network originates at a main control valve located in your garage area. This control valve should remain open at all times unless there is a non-fire emergency where the water supply needs to be shutoff. If the main control valve is closed, you do not have fire protection and you should notify your insurance carrier and your local fire department immediately, followed by calling your sprinkler contractor to have the problem repaired.


Each style of sprinkler has been spaced according to its approval listing, positioned from your walls at the proper distance and should not be tampered with.

Sprinklers should not be obstructed. Typical obstructions to sprinkler discharge include items such as walls, light fixtures, anything hanging from the ceiling, large ceiling height furniture, etc. If you have a question concerning a possible obstruction, please contact your fire sprinkler contractor or fire inspector.

We reccommend that you follow some simple operations and maintenance steps to ensure that your system continues to protect your home or business.

Shut down of system in case of a non-fire emergency.

• Shut the control valve for your system located in the garage area and call immediately for repairs to be done.

Tips to keep your sprinkler system in good working order.

• Never hang anything from the sprinkler heads, plates, or piping.

• Do not paint any part of the head or plate.

• Have a sprinkler contractor review any obstruction changes such as walls, cabinets, shelves or tall furniture.

Have your system tested by a licensed fire sprinkler inspector annually.

Have your system checked for any maintenance repairs by a licensed fire sprinkler      maintenance technician annually.
