LIFECO Standard and Quick Response Concealed Pendent Sprinkler LF820 and LF821 are thermosensitive glass-bulb spray sprinklers with the cover plate. The sprinkler is preassembled with a threaded adapter for installation with a low-profile cover assembly that provides up to 10mm of vertical adjustment. The two-piece design allows installation and testing of the sprinkler prior to installation of the cover plate. The “thread-on”, “thread-off” design of the concealed cover plate assembly allows easy installation of the cover plate after the system has been tested and the ceiling finish has been applied. The cover assembly can be removed and reinstalled, allowing temporary removal of ceiling panels without taking the sprinkler system out of service or removing the sprinkler.
