  • Patent number: 10862739
    Abstract: Systems and methods for dynamic output control hierarchy for wireless fire systems and for fire protection before and during the installation thereof are provided. Systems can include a fire system control panel, a gateway device coupled to the control panel, and a mesh network coupled to the gateway device. Responsive to the gateway device detecting a loss of communication with the control panel or a failure of the control panel, the gateway device can control activation of output devices in the mesh network. Responsive to a first device in the mesh network detecting a failure of the gateway device, the first device can control activation of the output devices in the mesh network. In some embodiments, the first device can control activation of the output devices of a second device in the mesh network, and in some embodiments, the first device can self-control activation of its own output devices.

  • Patent number: 9798966
    Abstract: Systems and methods of a smart card based mobile pull station are provided. For example, a smart card can include control circuitry and an activation mechanism. In some methods, the smart card can receive user input to activate the activation mechanism of the smart card, and upon activation of the activation mechanism, the control circuitry of the smart card can transmit an emergency signal. In some methods, a wireless device can receive the emergency signal from the smart card, the wireless device can transmit the emergency signal to a remote device, and the remote device can identify a location of the smart card based on a location of the wireless device.
