It is possible to put sprinkler heads atop a power distribution panel. As stated in the National Electrical Code 110.26 (commonly known as NFPA 70), automated sprinkler installation is permitted in electrical rooms when equipment is 600V or less, save for a few locations classified as ‘Dedicated Electrical Space’ (see below).

Can sprinkler heads be installed above panelboard?

To safeguard the electrical equipment, sprinkler heads have been put above the panelboard’s footprint, but none have been installed immediately above the panelboard itself. This installation is approved due to the fact that the sprinkler pipe and drip pan have been positioned above the allocated equipment space and that leak prevention has been fitted (see Figure 3).

Where should sprinklers not be placed in a building?

What is the maximum distance between two sprinkler heads?

The rating on the sprinkler head determines the maximum distance that may be maintained between two sprinklers (usually 15 feet, but there are other spacing distances, depending on the manufacturer). Six feet should be the minimum distance between two sprinklers.

Can sprinkler heads be covered?

  • Do you have a question about fire sprinklers?
  • The conundrum: failing to cover the sprinkler to protect it from overspray may result in the sprinkler failing to work correctly when it is needed owing to being covered in too much paint or residue, which will cause it to malfunction when it is needed.
  • However, covering it up in order to shield it from the harm caused by overspray may result in it malfunctioning instead.

What is the minimum distance between a sprinkler head and any obstruction?

Where should sprinkler heads be placed?

Sprinkler heads should always be arranged in such a way that the sprays overlap—that is, the distance thrown by one sprinkler head should reach the head of the next sprinkler head. This is referred to as ″head-to-head coverage,″ and in order to achieve it, sprinklers should be spaced evenly apart in each zone.

How far does a sprinkler head need to be from a wall?

The minimum and maximum four-inch separation from walls and ceilings vary depending on the form and size of the space, which is why conventional spray sprinklers have four-inch minimum and maximum spacing from walls and ceilings. For all conventional sprinkler heads, the minimum distance between the sprinkler head and the wall is four inches. The distance between two end walls is ten feet.

What is the maximum height of sprinkler head?

The maximum height of the ceiling must be 40 feet. The minimum working pressure for the installation should be either 30 psi or 60 psi, depending on the amount of storage space available and the height of the ceiling above it, as follows: 30 psi is required for storage heights of up to 25 feet.
