Claim 2
Dependent Claim
50 words
A sprinkler head comprising a cover plate which is operated to fall down at a temperature lower than the operating temperature of said sprinkler head body, wherein: switching means is provided for detecting the falling of said cover plate and sending a fire detection signal to said sprinkler head body.
Claim 3
Dependent Claim
55 words
A sprinkler head according to claim 1, wherein said cover plate comprises a cover plate body, a synthetic resin piece for engaging said cover plate with said sprinkler head body and a metal plate fixed to said cover plate by a heat resistant adhesive and fixed to said cover plate body by a low-temperature solder.
Claim 4
Dependent Claim
83 words
A sprinkler head according to claim 1, wherein said cover plate comprises a cover plate body, a synthetic resin piece for engaging said cover plate with said sprinkler head body, and a spring plate engaged with said synthetic resin piece and fixed to said cover plate by low-temperature solder, a compression spring being interposed between said cover plate and said synthetic resin piece so as to be urged in the direction in which said cover plate is separated from said synthetic resin piece.
Claim 5
Dependent Claim
60 words
A sprinkler head according to claim 1, wherein said cover plate comprises a cover plate body and an engaging piece made of a shape memory alloy which is fixed to said cover plate so as to engage with said sprinkler head body at a normal temperature and released from the engagement with said sprinkler body when the temperature is increased.
Claim 6
Dependent Claim
75 words
A sprinkler head comprising switching means provided on a side of the sprinkler head body so as to send a fire detection when said means is operated at a temperature lower than the operating temperature of said sprinkler head and a sprinkler head operation signal when said means is returned to a non-operating state by detection of the firewater discharged by the operation of said sprinkler head after said fire detection signal has been sent.
Claim 7
Dependent Claim
75 words
A sprinkler head comprising switching means provided on a side of the sprinkler head body so as to send a fire detection when said means is operated at a temperature lower than the operating temperature of said sprinkler head and a sprinkler head operation signal when said means is returned to a non-operating state by detection of the firewater discharged by the operation of said sprinkler head after said fire detection signal has been sent.
Claim 8
Dependent Claim
128 words
An operation monitor for a sprinkler head comprising switching means provided on the side of the sprinkler head body so as to send a fire detection when said means is operated at a temperature lower than the operating temperature of said sprinkler head and a sprinkler head operation signal when said means is returned to a non-operating state by the detection of the firewater discharged by the operation of said sprinkler head after said fire detection signal has been sent, wherein: when said monitor receives said sprinkler head operation signal from said switching means provided on said sprinkler head and said detection signal from a water flow detector provided in piping of said sprinkler head, said monitor decides that said sprinkler head is operated and indicates the operation.
Claim 9
Dependent Claim
128 words
An operation monitor for a sprinkler head comprising switching means provided on the side of the sprinkler head body so as to send a fire detection when said means is operated at a temperature lower than the operating temperature of said sprinkler head and a sprinkler head operation signal when said means is returned to a non-operating state by the detection of the firewater discharged by the operation of said sprinkler head after said fire detection signal has been sent, wherein: when said monitor receives said sprinkler head operation signal from said switching means provided on said sprinkler head and said detection signal from a water flow detector provided in piping of said sprinkler head, said monitor decides that said sprinkler head is operated and indicates the operation.
