An automatic addressing system for a fire loop and a method for automatically addressing a plurality of remote units electrically connected to a fire panel in a fire loop, the method including: (1) requesting an initial identifier from each remote unit; (2) for each remote unit which responds with a unique initial identifier: (a) assigning a unique address to the remote unit; and (b) silencing the response of the configured remote unit to further identifier requests; (3) for each remote unit which responds with an initial identifier matching the initial identifier of at least one other remote unit: (a) initialising an identifier array with the initial identifier for the remote unit in question; (b) requesting a further identifier and adding it to the identifier array for the remote unit; (c) for each remote unit which responds with a unique identifier array: (i) assigning a unique address to the remote unit.

An optical fiber sensing system according to the present disclosure includes an optical fiber (10) that detects vibration, a detection unit (21) that detects occurrence of a predetermined event, based on an optical signal on which vibration detected by the optical fiber (10) is superimposed, an identification unit (22) that identifies an occurrence location of the predetermined event, based on the optical signal, and identifies a movement destination area serving as a moving destination of an unmanned aerial vehicle that monitors an occurrence location of the predetermined event, based on an occurrence location of the predetermined event, and a control unit (23) that controls the unmanned aerial vehicle to move to the movement destination area.

A fire system 10 for a building is provided, the fire system 10 including a fire panel 12 for monitoring the building and activating an alarm; and a plurality of remote units 14, 16, 18 electrically connected to the fire panel 12 in a circuit 20 having a loop configuration. At least some of the plurality of remote units 14, 16, 18 including an indicating device 14, 18 for modulating a current in the circuit 20. The plurality of remote units 14, 16, 18 are in communication with the fire panel 12 in a master-slave relationship. The fire panel 12 includes a calibration module 22 for polling each indicating device 14, 18 to obtain a current response value and for storing said current response values, the current response value of an indicating device 14, 18 being based on the amplitude of the current when modulated by that indicating device.

A gunshot detection system synchronizes timing information across gunshot sensor units and/or a control panel. The gunshot sensor units exchange timing information with each other and/or with the control panel, which is then used by the gunshot sensor units to generate the event data for detected gunshot events. In one embodiment, the gunshot sensor units are configured as master and slave nodes. The master node periodically distributes a master time reference to the slave nodes, and the slave nodes calibrate local times based on the master time reference. The slave nodes can detect whether the current master node has become non-functional (e.g. based on a time elapsed since the most recently sent master time reference) and configure a new master node based on exchanging predetermined priority information for the slave nodes.

An object is to accurately detect abnormality of a living body. A living body abnormality detection device comprises: a signal acquirer that acquires a first signal including a frequency component of heartbeat; a filter that attenuates a frequency component higher than the frequency component of heartbeat and a frequency component lower than the frequency component of heartbeat based on the first signal to generate a second signal; a frequency analyzer that indicates an analysis result obtained by analyzing a frequency component of the second signal based on the second signal; an energy proportion calculator that calculates an energy proportion that is a proportion occupied by energy of a frequency component for each frequency band with respect to entire energy in the second signal based on the analysis result; a variance value calculator that calculates an energy variance value of a frequency component for each frequency band based on the analysis result; and a detector that at least detects abnormality or normality of a living body based on either one of the energy proportion and the variance value or both of the energy proportion and the variance value.

Systems and methods for interfacing a hazard detection device with a control panel system via a dongle are provided. The dongle may be configured to alternate between drawing first and second amounts of power from the control panel system in response to the hazard detection device alternating between operating in a normal mode when no hazard is detected and an alarm mode when a hazard is detected. The hazard detection device may operate independently of any characteristics of the control panel system. For example, the hazard detection device may operate without drawing any power from the control panel system. Therefore, the dongle may allow for various types of hazard detection devices to interface with a common two-line power control system.
