Abstract

A bulb device 100 for a sprinkler device 200 of a fire suppression system, and a method of manufacturing a bulb device 100 . The bulb device 100 includes a sprinkler bulb 101 ; a wireless communication device 120 ; and a coupling 150 affixing the wireless communication device 120 to an external surface of the sprinkler bulb 101.

Claims (20)

1 . A sprinkler device for a fire suppression system, the sprinkler device comprising:

a bulb device ( 100 ) comprising:

a sprinkler bulb ( 101 );

a wireless communication device ( 120 ); and

a coupling ( 150 ) affixing the wireless communication device ( 120 ) to an external surface of the sprinkler bulb ( 101 );

wherein the wireless communication device comprises an RFID tag;

wherein the coupling ( 150 ) is disposed between the wireless communication device ( 120 ) and the sprinkler bulb ( 101 );

an antenna ( 220 ) for communicating with the wireless communication device ( 120 ) of the bulb device ( 100 ); and

a base plate ( 230 ), wherein the antenna ( 220 ) is disposed within the base plate ( 230 ).

2 . A sprinkler device as claimed in claim 1 , wherein the coupling ( 150 ) reinforces the sprinkler bulb ( 101 ) adjacent the wireless communication device ( 120 ).

3 . A sprinkler device as claimed in claim 1 , wherein the sprinkler bulb ( 101 ) only contains fluid ( 130 ).

4 . A sprinkler device as claimed in claim 1 , wherein the wireless communication device ( 120 ) is a passive wireless communication device.

5 . A sprinkler device as claimed in claim 1 , wherein the bulb device ( 100 ) is arranged to propel the wireless communication device ( 120 ) away from the sprinkler bulb ( 101 ) upon activation of the sprinkler bulb ( 101 ).

6 . A sprinkler device as claimed in claim 1 , wherein the coupling ( 150 ) is configured to protect the wireless communication device ( 120 ) from the sprinkler bulb ( 101 ) during activation.

7 . A sprinkler device as claimed in claim 1 , wherein the antenna ( 220 ) is a coil antenna.

8 . A sprinkler device as claimed in claim 1 , wherein the sprinkler bulb ( 101 ) of the bulb device ( 100 ) is coaxial with the antenna ( 220 ).

9 . A sprinkler device as claimed in claim 1 , wherein the base plate ( 230 ) is formed of metal, heat resistant polymer, glass, and/or composite.

10 . A sprinkler device as claimed in claim 1 , comprising a flux concentrator ( 240 ) arranged to concentrate flux from the antenna ( 220 ) at the bulb device ( 100 ).

11 . A sprinkler device as claimed in claim 1 , wherein the antenna ( 220 ) is configured to use signals in the frequency range of 100 kHz to 160 kHz.

12 . A method of operating a fire suppression system, the method comprising providing a sprinkler device as claimed in claim 1 ; positioning the bulb device ( 100 ) in the sprinkler device ( 200 ); and propelling the wireless communication device ( 120 ) away from the sprinkler device ( 200 ) by activation of the sprinkler bulb ( 101 ) of the bulb device ( 100 ).
