A sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected,
such as when a predetermined temperature has been exceeded.
Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year.
In buildings protected by properly designed and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone.
Paratech Standard and Quick Response Concealed Pendent Sprinkler PI820 and PI821 are thermosensitive glass-bulb spray sprinklers with the cover plate.
The sprinkler is pre-assembled 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.
