The Tyco RFIII extended-coverage horizontal sidewall sprinkler is an 8.0 K-factor unit rated for light hazard occupancies. The sprinkler covers areas to 16 ft. x 24 ft. and 18 ft. x 22 ft. The device has a flat cover that conceals the sprinkler within the wall, providing a clean look for architecturally sensitive applications. The flat profile aids in preventing damage and interruption from accidental activations. The cover-plate assembly is available in a variety of standard colors or custom colors. The push-on closure allows a 1/2-in. adjustment.
