Key Terminology
- Hazard Classification: Categorizes occupancy based on the quantity and combustibility of materials present (e.g., Light, Ordinary, Extra Hazard).
- Maximum Protected Area: The largest floor area that a single sprinkler head is designed and listed to protect effectively under given conditions.
- Sidewall Sprinkler: A sprinkler designed to be installed along a wall or beneath a beam, projecting water in a crescent-shaped pattern.
- Pendent/Upright Sprinkler: Standard sprinkler types that project water upward against a deflector, creating a hemispherical spray pattern below the ceiling.
