Approved drop out (or drop-out) ceilings allow the installation of a dropped ceiling beneath existing fire sprinklers because the tiles, sometimes called melt-out ceiling tiles, are heat-sensitive and are designed to fall from the dropped ceiling suspension grid during a fire, allowing the sprinklers to spray their water.
A fire sprinkler mounted on a ceiling. A fire sprinkler or 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.
A sign warns hotel guests not to hang items from fire sprinklers. Each closed-head sprinkler is held closed by either a heat-sensitive glass bulb or a two-part metal link held together with fusible alloy. The glass bulb or link hold in place a "pip cap" which acts as a plug to prevent water from flowing, unless the ambient temperature around ...
A sprinkler system having pressurized air (rather than water) in the distribution pipes until a heat-activated sprinkler head opens and releases the stored air pressure, which in turn opens the main water valve (and possibly an accelerator valve) to flow water to the open sprinkler(s); used where the protected premises are not heated during ...

In order to be "matched" all sprinkler heads in a given zone must have the same rate of precipitation. This can be achieved by matching the gallonage of a standard rotor to its arc and reducing range accordingly (i.e. 2 gallons at 90 degrees, 4 gallons at 180 degrees, or 8 gallons if the head does a full circle) or by using MPR nozzles or ...
