摘要： A fusible link assembly including a first detection line, a second detection line, and a fusible link. The fusible link includes, a first substrate with a first end coupled to the first detection line, a second substrate with a first end coupled to the second detection line, and a solder layer directly bonded to a second end of the first substrate and a second end of the second substrate. The solder layer is configured to prevent separation of the first substrate and the second substrate until the solder layer reaches a temperature between 500° F.-575° F.

摘要： A grate assembly includes a grate and a nozzle. The grate includes a nozzle aperture. The nozzle is received by the nozzle aperture. The nozzle includes a base and a baffle coupled to the base. The base and the baffle define a plurality of flow paths. The nozzle also includes a deflector ring removably positioned between the baffle and the base. The deflector ring includes a body that defines a spray outlet, wherein the body allows fluid flow through one or more flow paths aligned with the spray outlet and prevents fluid flow through the remaining flow.

摘要： A communication system includes a first radio frequency identification (RFID) device coupled to a sensor that monitors a fire condition and a second RFID device. The first RFID device includes at least one first antenna that receives a fire detection signal from the sensor, and a processing circuit that causes the at least one first antenna to transmit a radio frequency (RF) signal corresponding to the fire detection signal through an internal volume of a pipe coupled to a fluid source. The second RFID device includes at least one second antenna that receives the RF signal through the internal volume of the pipe. The second RFID device controls operation of a fluid distribution device responsive to receiving the indication of the fire detection signal.

摘要： A tire protection sprinkler including a frame body having an inlet, an outlet, defining an internal passageway extending between the inlet and the outlet along a sprinkler axis. A dome shaped deflector member is centered, axially aligned with the sprinkler axis, and spaced from the outlet. The deflector member has an outer surface and an inner surface that preferably includes: a peripheral region, a central region and an intermediate region. The intermediate region includes a primary deflecting surface, and a secondary deflecting surface that is surrounded by the primary deflecting surface The deflector member provides for generation of a non-circular spray pattern defined by four zones of fluid density concentrically formed about the sprinkler axis.

摘要： A modular fire suppression unit includes a housing, an off-gas detector, a fire suppression apparatus, and a controller. The off-gas detector is provided within the housing and is configured to obtain air samples and detect a presence of off-gas in each air sample. The fire suppression apparatus is provided within the housing and configured to provide a fire suppression agent to a space. The controller is provided within the housing and is configured to receive signals from the off-gas detector indicating whether off-gas is detected in each of the air samples. The controller is also configured to activate the fire suppression apparatus to provide the fire suppression agent to the space in response to detecting off-gas in one or more of the air samples. The modular fire suppression unit is configured to be coupled to a sidewall of an enclosure.

摘要： A rotational coupling including a bearing assembly including a first race rotatably coupled to a second race, wherein the first race is configured to receive a plurality of first fasteners to couple the first race and the bearing assembly to a fluid supply. The rotational coupling also including a connection flange coupled to the second race and configured to receive a plurality of second fasteners to couple the connection flange to the second race. The second race includes a first side facing the connection flange and a second side opposite the first side and facing the first race, wherein the second race includes at least one access aperture configured to enable access to the plurality of first fasteners from the first side to removably couple the bearing assembly to the fluid supply.

摘要： A receiver for a fire suppression system includes a receiving portion configured to receive and couple with a corresponding portion of a cartridge. The receiver includes a translatable member configured to engage a corresponding portion of the cartridge and translate in response to insertion of the cartridge. The receiver includes a switch configured to transition between a first state and a second state in response to translation of the translatable member to indicate whether the cartridge is inserted into the receiving portion.
