Can sprinkler heads be installed above an electrical switchboard?

According to NEC 110.26 (also known as NFPA 70), automatic sprinkler installation is allowed in electrical rooms where equipment is 600V or less, except for certain spaces called “Dedicated Electrical Space.” These spaces are directly above the electrical equipment (please refer to NEC 110.26 for exact definition).

What is a fire sprinkler riser room?

How much clearance is needed for a fire sprinkler?

As a general rule, NFPA 13, Installation of Sprinkler Systems, requires 18 inches of clearance, but makes the following modifications: For standard pendent and upright spray (SSP/SSU) sprinklers, the 18- inch dimension is not intended to limit the height of shelving or storage along a wall as illustrated below.

Does a fire riser need to be enclosed?

You only need a door that opens directly to the outside if you have a fire pump in that room. NFPA states: Except as provided in 4.13. 1.1, fire pump rooms not directly accessible from the outside shall be accessible through an enclosed passageway from an enclosed stairway or exterior exit.

Are floor drains required in fire riser rooms?
