Abstract
An automatic sprinkler of fire detector type being electrically switchable when the sprinkler is opened due to detachment of heat actuatable element from the sprinkler is provided, and, thus, fire-protective signaling and controlling system associated with a sprinkler system including the automatic sprinkler of fire detector type can be activated by electrical switching of the automatic sprinkler of fire detector type when fire occurs. And, in a sprinkler system having non-wet piping network and normally closed deluge valve, it is possible that opening of the deluge valve can be made by electrical switching of the automatic sprinkler of fire detector type.
Claims22
An automatic sprinkler of fire detector type having an electric switch fixed to a base of the sprinkler in such a manner that:
- an electric contact of the electrical switch, being electrically insulated from the base of the sprinkler, is normally held in one of an ON and an OFF position by a force pushing the electric contact, the pushing force extending from contact between the electric switch and a part of a heat actuated element of the sprinkler;
- and
- an automatic sprinkler system comprising the automatic sprinkler of fire detector type is characterized in that the sprinkler system has a configuration by which operation of a protective signaling and controlling system including fire indicating appliance circuits and operating equipment or device circuits can be initiated by opening of the automatic sprinkler.
An automatic sprinkler of fire detector type having a base and an electric switching mechanism comprising:
- two electric contacts electrically insulated from the base of the sprinkler and normally positioned apart from but close to a heat actuated element of the sprinkler;
- and
- a water column formed by water discharged out of an orifice of the sprinklers;
- wherein the two electric contacts come into contact with the water column formed by water discharged out of the orifice, the orifice is opened due to detachment of the heat actuated element, and the water column functions as an electrical bridge to permit flow of an electric current between the two electric contacts to be electrically energized.
An automatic sprinkler of fire detector type having an electric switch fixed to a base of the sprinkler in such a manner that:
- an electric contact of the electrical switch, being electrically insulated from the base of the sprinkler, is normally held in one of an ON and an OFF position by a force pushing the electric contact, the pushing force extending from contact between the electric switch and a part of a heat actuated element of the sprinkler;
- and
- a sprinkler system comprising the automatic sprinkler of fire detector type is characterized in that the above sprinkler system can employ fire pump to be driven by speed-changeable motor controlled by a computer to be hydraulically pre-programmed so as to supply fire water adjusted quantitatively in accordance with the number of opened sprinklers.
An automatic sprinkler of fire detector type having an electric switch fixed to a base of the sprinkler in such a manner that:
- an electric contact of the electrical switch, being electrically insulated from the base of the sprinkler, is normally held in one of an ON and an OFF position by a force pushing the electric contact, the pushing force extending from contact between the electric switch and a part of a heat actuated element of the sprinkler;
- and
- a sprinkler wet-pipe system having the automatic sprinkler of fire detector type is characterized in that the sprinkler wet-pipe system operates such that every fire occurring in one or more zones of an area protected by the sprinkler wet-pipe system is monitored by an indicating appliance circuit associated with at least one automatic sprinkler installed in every zone.
