LIFECO Concealed Pendant Type Sprinkler

Concealed pendant sprinklers include a cover plate assembly that conceals the sprinkler operating component above the ceiling. The cover plate assembly, which installs on to the sprinkler/mounting cup assembly consists of a cover plate that is soldered to an enclosure at three equidistant locations around their peripheries, the ejection spring is located between the flange of the enclosure and the cover plate, to ensure separation of the two pieces when the solder melts.
