All standard sprinkler heads—pendent, upright, and sidewall—have the same minimum sprinkler distance from walls: four inches. For sidewall heads, that's the distance from an end wall (10.3. 4.3.
Sprinklers shall be located a minimum of 4 in. (100 mm) from a wall.
Sprinklers shall be located a minimum of 4 in. (100 mm) from an end wall. Sprinklers shall be spaced not less than 6 ft (1.8 m) on center unless required by 10.3. 5.1.
Sprinkler spacing.
The minimum vertical clearance between sprinklers and material below shall be 18 inches (45.7 cm).
Nothing should be in that area between the bottom of the sprinkler heads and the imaginary horizontal plane parallel to the ceiling that is 18 inches below. This is done to allow an even and unobstructed spray pattern from the sprinklers when triggered to extinguish the fire.
1.3 lays out the “Three Times Rule” which states that unless specific requirements are met that “sprinklers shall be positioned away from obstructions a minimum distance of three times the maximum dimensions of the obstruction”, up to a maximum of 24 inches (0.6096 m) though the “maximum clear distance does not apply ...
A common rule that is followed for obstructions within 18 inches of the sprinkler deflector is the “three times rule”. This requires sprinklers to be positioned away from obstructions a minimum or three times the maximum dimension of the obstruction.
The sprinklers spray at an angle of approximately 45 degrees. So of your light fixture is 4 inches deep, then you should keep them at least 4 inches away from the sprinkler heads.
5.1. 1.2 are met, sidewall sprinkler deflectors shall be located not more than 6 in. (150 mm) or less than 4 in. (100 mm) from ceilings.
3.6(d) a clear space not less than 500 mm shall always be maintained below the level of the sprinkler deflectors throughout the room.
Current fire safety codes require sprinkler heads always to be a minimum of 6 feet apart from one another to avoid cold soldering.
Do not install cable trays, heating ducts or other large obstructions closer than 3 times its width, to a sprinkler head. (i.e. if the duct is 2 ft (0.6 m) wide, then it should be 6ft (1.8 m) from the sprinkler head.)
The sprinkler can cover 16 feet wide by 24 feet long area. The Sprinkler operating device is state of the art heat responsive frangible glass bulb supplied by a world leader in this innovative technology. The glass bulb contains fluid which expands when exposed to heat.
If you are using a spray-type and if you will use a radius rotor-type heads keep it away for 3 feet or more from the structures. Regardless of wherever you will place them, remember to consider that the wind can also affect where water spray goes.
A minimum 3-foot clearance in front of the entire width of the fire sprinkler equipment and 1-foot clearance on the remaining 3 sides shall be provided.
HD Vertical Sidewall Sprinkler is a small, thermosensitive, glass-bulb spray sprinkler available as standard or quick response type in temperature ratings to meet design requirements. Sprinkler is UL Listed.
Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern in order to control or extinguish fire. Horizontal sidewall sprinkler are designed for installation along a wall or the side of a beam and just beneath a smooth ceiling.
All standard sprinkler heads—pendent, upright, and sidewall—have the same minimum sprinkler distance from walls: four inches. For sidewall heads, that's the distance from an end wall (10.3. 4.3.
The best way to prevent accidental spraying of the fence is to place the sprinkler system at least two feet apart from the structure. This is a safe distance from the fence and can reduce problems and ensure your fencing isn't damaged due to water or moisture build-up.
NFPA-13 states that sprinkler protection is NOT required above hung ceilings if the area above has non-combustibles even with small openings in the ceiling.
You can operate 2 or 3 sprinklers at one time with 'Y's and extra hoses, depending on your water pressure. To run more than one sprinkler off the same faucet, attach a 'Y' to your faucet and run a hose to each sprinkler.
Or, if you prefer, simply leave the irrigation design up to an installation professional, so you can be guaranteed head-to-head coverage. Typically, though, a sprinkler system zone will boast 5 to 6 rotor heads and/or 8 to 10 spray heads.
Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.
This insulation can protect pipe from sunlight in above-ground systems and protects against freezing during the winter. If you choose to use PVC pipe for your irrigation laterals, make sure to use pipe that is at least 3/4" thick.
