What is the minimum water supply duration required for a light hazard sprinkler system according to NFPA 13?
Answer: 30 minutes
NFPA 13 requires a minimum 30-minute water supply duration for light hazard sprinkler system design.
Which type of sprinkler system is required in areas subject to freezing temperatures?
Answer: Dry pipe system
Dry pipe systems use pressurized air or nitrogen in the pipes instead of water, preventing freezing in cold environments.
What does the K-factor of a sprinkler head represent?
Answer: The discharge coefficient relating flow to pressure
The K-factor is a discharge coefficient used in the formula Q = K√P to calculate the flow rate from a sprinkler at a given pressure.
Under NFPA 13, what is the minimum required pressure at the most remote sprinkler in a hydraulically designed system?
Answer: 10 psi
NFPA 13 requires a minimum operating pressure of 7 psi at the most hydraulically remote sprinkler to ensure adequate discharge.
What type of sprinkler activates all heads simultaneously when the detection system triggers?
Answer: Deluge sprinkler
A deluge system has open sprinkler heads and floods the entire protected area simultaneously when the detection system activates the deluge valve.
Which NICET certification covers water-based fire protection systems?
Answer: NICET Water-Based Systems Layout
NICET offers a Water-Based Systems Layout certification for technicians who design and lay out sprinkler and other water-based fire suppression systems.
