A sprinkler devicefor a fire suppression system, the sprinkler deviceincluding: a sprinkler bulbcomprising a first antenna. The sprinkler devicealso includes a second antennafor communicating with the first antenna of the sprinkler bulb, and a base plate, wherein the second antennais disposed within the base plate

Sprinkler device

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 system includes a fire panelhaving a loop driver. A combined detection and suppression loopis connected to the loop driver. A plurality of fire detection devicesand a plurality of fire suppression devicesare coupled to the detection and suppression loop. The fire suppression devicesincludes multiple sprinkler devices, each of the sprinkler devicesincluding a sprinkler bulband a circuit. The circuitof the sprinkler deviceis detectable via the fire panelusing the detection and suppression loopin order to provide information from the sprinkler deviceto the fire panel

Fire system

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

A presence detection system () including: an RFID interrogator (); and a plurality of passive RFID tags (to MN), the RFID interrogator () is configured to: measure a received signal strength indicator (RSSI) level from each of the plurality of passive RFID tags (to MN); compare a measured RSSI level to a reference RSSI level for each of the plurality of passive RFID tags (to MN); and determine whether a difference between the measured RSSI level and the reference RSSI level is greater than a threshold value.

Presence detection using RFID tags and readers

Disclosed is a sprinkler system including a controller, wherein when the sprinkler system is in a pressurized mode, the controller is configured for: rendering a first determination to transition the sprinkler system to a standby mode, and executing a first communication with a vacuum pump based on the first determination, the first communication directing the vacuum pump to activate, whereby fluid is drained from the sprinkler system.

Pop-out sprinkler with vacuum actuated push-back

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.
