Sprinkler heads must be installed and maintained according to National Fire Protection Association (NFPA) standards. Install using sprinkler-head wrenches (sold separately) or any hand wrench that fits the NPT size.

Pendent-style sprinkler heads are designed to be suspended below support piping. They can be used with exposed piping or finished ceilings.

Upright-style sprinkler heads are designed to be installed above support piping and can only be used with exposed piping.

Glass-bulb sprinkler heads are triggered when the liquid-filled bulb bursts at the rated temperature.

Fusible-link sprinkler heads are triggered by a soft metal alloy that melts at the rated temperature.

Concealed Fire Sprinkler Heads

An inconspicuous cover plate provides a clean look for sprinkler heads. When the plate's temperature rating is reached, it falls away to expose the sprinkler head. The head itself has a liquid-filled glass bulb that bursts at the rated temperature to trigger the sprinkler. Install using required wrenches (sold separately).
