ABSTRACT

Coffee Break Training: Automatic Sprinklers: Sprinkler 'Heat Collectors'   [open pdf - 268KB]

"Look closely beneath the windows and you will see two sidewall sprinklers. Each sprinkler has a small (about 8 ½ x 11-inches [216 to 280 mm]) panel mounted immediately above it. Although not visible in the picture, there are no sprinklers at the ceiling of this large opening between two floors of a hotel. These panels are intended to serve as nominal 'heat collectors,' to trap thermal plumes from a fire long enough to open the adjacent sprinklers to discharge water onto the floor area below. 'Heat collectors' often are installed when the sprinkler design or installation does not comply with the requirements in NFPA [National Fire Protection Association] 13, 'Standard for the Installation of Automatic Sprinkler Systems', for the maximum distance between a ceiling and a sprinkler deflector."
