The invention relates to a sprinkler bulb comprising a sealed frangible housing, and a circuit devicewithin the housing, wherein the circuit device comprises a capacitorarranged to be used as a pressure sensor. The invention also relates to a method of measuring pressure inside a sprinkler bulb using a capacitorof the circuit devicewithin a housingof the bulb as a pressure sensor.

Sprinkler bulb

A sprinkler includes a sprinkler body having a fluid inlet; a seal configured to prevent fluid flow through the sprinkler body when the seal is in a first position; a bulb configured to retain the seal in the first position, the bulb configured to break at a temperature and allow the seal to move to a second position allowing fluid flow through the sprinkler body; and an identification device located within the bulb.

Sprinkler and sprinkler system including same

Provides are embodiments of a sprinkler and sprinkler system. The embodiments include a sprinkler body having a fluid inlet, a seal configured to prevent fluid flow through the sprinkler body when the seal is in a first position, and a bulb configured to retain the seal in the first position, the bulb configured to break at a temperature and allow the seal to move to a second position allowing fluid flow through the sprinkler body. The bulb includes a wireless power and communication unit configured to receive a wireless activation signal, an energy storing unit configured to store energy for a heating element, a control unit operably coupled to the wireless power and communication unit and the energy storing unit, and the heating element configured to supply the energy to the fluid in the bulb responsive to a trigger.

Fire sprinkler with remote release function

Provided are embodiments including a sprinkler, a method for operating a sprinkler, and a sprinkler system. Embodiments include receiving a signal and triggering a test of a bulb responsive to the signal. Embodiments include heating fluid in the bulb responsive to the triggering the test. Embodiments also include detecting a condition of the bulb, wherein the one or more sensing elements are in contact with the fluid in the bulb, and transmitting a notification to a device indicating the condition of the bulb.

Crack detection function for a fire sprinkler with frangible bulb

There is provided a sprinkler device, comprising: a sprinkler bulbcomprising a sealed frangible housing, and a passive circuit devicewithin the housing, wherein the passive circuit devicecomprises a wireless module; and a base stationconfigured to detect pressure changes inside the sprinkler bulbvia the wireless module. A method of testing integrity of a sprinkler bulb is also provided, comprising: monitoring a pressure change within the sprinkler bulbvia a wireless moduleof a passive circuit deviceinside a sealed frangible housingof the sprinkler bulb; and determining that the sprinkler bulb is in working order if the pressure reaches a predetermined threshold; or determining that the sprinkler bulb is not in working order if the pressure does not reach the predetermined threshold.
