Embodiment Construction

[0031] Sprinklers are distributed throughout the area to provide fire suppression in the event of a fire. Over a period of time, the sprinklers need to be inspected to ensure that the sprinklers are operational. Inspection includes a visual inspection by an operator observing the blisters. Damage to the blister may occur during transport from the manufacturer to the customer, during installation, or a defect in the blister. Microcracks in the bubble can cause improper operation of the bubble where sufficient pressure will not build up within the bubble to rupture the bubble to activate the sprinkler.

[0032] Existing solutions for crack detection of frangible bubbles of fire sprinklers are based on visual inspection of the bubbles and are complex for field application. Additionally, due to the subjectivity and experience of the technician performing the inspection, existing solutions may provide imprecise results and are limited to detecting only significant differences.

Abstract

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.

Description

technical field [0001] The present disclosure relates generally to sprinkler installations, and more specifically to performing crack detection functionality on IoT fire sprinklers with frangible bubbles. Background technique [0002] A sprinkler system typically includes a plurality of sprinklers for discharging a fire suppression fluid in the event of a fire. The system may use "smart" sprinklers equipped with wiring, sensors, processors, etc. to track the position and / or status of each sprinkler. Such sprinklers may be difficult to install on existing water distribution networks due to the electronics that must be implemented within the sprinkler body. Furthermore, such installations may require additional certification prior to operation. Finally, installed systems require regular maintenance, which can become a manually cumbersome task. Contents of the invention [0003] According to one embodiment, a sprinkler is provided. The sprinkler includes: a sprinkler body...
