Fire Sprinkler Helpful Tips:
Tip 1: When replacing cover plates, it is important to purchase replacements from the same manufacturer as the fire sprinkler. Each manufacturer's cover plate is a little different in size, color, etc. Manufacturer and temperature of a cover plate is printed on the base of the plate requiring removal to inspect. Most cover plates are either twist off or pull off.
Tip 2: It is recommended that a qualified professional replace fire sprinklers or in any other way modify a fire sprinkler system.
Tip 3: A fire sprinkler's size describes the inner orifice diameter - either half (1/2") or three-quarter (3/4") inch. The outer diamter of a (1/2") sprinkler's threads measures close to three-quarter inch. The other diameter of a (3/4") sprinkler's threads is measures close to one inch. Most offices, small retail locations, etc. have (1/2") sprinklers.
Tip 4: Try always to match the sprinkler's response type to the one you're replacing. Replace quick response fire sprinklers with quick response fire sprinklers. Replace standard response fire sprinklers with either quick response or standard response. Equal or better!
Tip 5: Spare fire sprinkler heads and a wrench should be accessible at all times in a facility with a commercial fire sprinkler system installed. Often state regulations apply, too. Check with your local fire department.
Tip 6: Fire sprinkler systems should be visually inspected often and professionally inspected annually.
