  • Patent number: 10184831
    Abstract: A method for calibrating a test light to simulate a fire includes measuring a baseline resistance induced in a sensor cell of a two-color detector in response to a controlled fire. The method includes monitoring a test resistance induced in the sensor cell in response to exposure to emissions from a test light and adjusting the emissions of the test light until the test resistance of the sensor cell equals the baseline resistance of the sensor cell to achieve a calibration setting for the test light. A test light for a detector includes a housing and a first LED within the housing having a first emission wavelength. A second LED is within the housing. The second LED has a second emission wavelength. The second emission wavelength is different than the first emission wavelength.

    Abstract: A detector that detects an alarm and/or fault condition with respect to a pressure of a medium is provided. The detector comprises a housing comprising an access tube configured to receive a medium and a bellows fixed to the housing comprising a cavity and a first contact surface. The detector also comprises an adjustment screw positioned within the cavity of the bellows, coupled to the housing via an insulation member, and comprising a second contact surface. The detector is further configured to detect a change in pressure of the medium based on whether the first contact surface and the first contact surface are in electrical communication.

  • Patent number: 9649520
    Abstract: According to one aspect, a fire extinguisher actuator assembly for a fire extinguisher is provided. The fire extinguisher includes a fire extinguisher reservoir and a burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent within the fire extinguisher reservoir. The fire extinguisher actuator assembly includes a cutter shuttle assembly having a cutter coupled to a shuttle body. The cutter shuttle assembly is detained within the fire extinguisher proximate the burst disc and biased to form a pressure equalization region between the shuttle body and the burst disc. The fire extinguisher actuator assembly also includes an activation device having a piercing member operable to pierce the burst disc and release pressure from the pressure equalization region, thereby driving the cutter through the burst disc to release the pressurized fire extinguishing agent through the discharge head.

  • Patent number: 9539452
    Abstract: According to one aspect, a fire extinguisher includes a fire extinguisher reservoir and a fire extinguisher outlet burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent at an internal fire extinguisher pressure within the fire extinguisher reservoir. A cutter is detained within the fire extinguisher proximate the fire extinguisher outlet burst disc. An interior container within the fire extinguisher reservoir has a container pressure and is sealed with a container burst disc. An activation device having a piercing member is operable to pierce the container burst disc and diffuse the container pressure to create a pressure differential relative to the internal fire extinguisher pressure at the cutter, thereby driving the cutter through the fire extinguisher outlet burst disc to release the pressurized fire extinguishing agent through the discharge head.
