A sounder apparatus 100 includes a sounder 110 having at least two volume settings, at least one detector 120, a micro-controller wherein the micro controller is configured to receive an input signal from the at least one detector 120, and to control the volume setting of the sounder based on the input signal.

A hub device including a housing defining an interior, a plurality of sensors, and a controller module. The plurality of sensors being provided within the interior or along a portion of the housing. The controller module having access to a memory comprising a set of preloaded software and a set of additional software. At least one of least one of the set of preloaded software or the set of additional software is configured to allow the hub device to be communicatively couplable to at least one additional hardware.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying wildfire in satellite imagery. In some implementations, a server obtains a satellite image of a geographic region and a date corresponding to when the satellite image was generated. The server determines a number of pixels in the satellite image that are indicated as on fire. The server obtains satellite imagery of the geographic region from before the date. The server generates a statistical distribution from the satellite imagery. The server determines a likelihood that the satellite image illustrates fire based on a comparison of the determined number of pixels in the satellite image that are indicated as on fire to the generated statistical distribution. The server can compare the determined likelihood to a threshold. In response to comparing the determined likelihood to the threshold, the server provides an indication that the satellite image illustrates fire.

Methods and systems for performing a walk test for fire alarm systems using a mobile device are described herein. One fire alarm system, includes a system control panel fixedly positioned within a building for controlling a plurality of fire alarm system devices connected to the panel and positioned within the building, a mobile device wirelessly connected to the control panel, and a fire alarm system control application on the mobile device, wherein the fire alarm control system application gains access to the control panel and, therethrough, the plurality of fire alarm system devices and wherein the fire alarm control system application issues a command to a particular fire alarm system device of the plurality of fire alarm system devices to perform a particular test or maintenance function and the control panel relays the command to the particular fire alarm system device.

A system and methods are provided for community outdoor fire protection comprising: receiving indicators of a current fire, and responsively determining a level of the current fire risk for each of multiple endpoints of a shared water supply; determining a relative duty cycle for operating each endpoint according to a fire risk; receiving a water pressure measurement of the shared water source and determining a maximum number of concurrent endpoints to operate; accordingly allocating operation of each endpoint to a set of time slots; and activating the multiple endpoints to turn on respective water flows according to the time slot allocation.

A fire protection system includes a first transceiver communicatively coupled with a first end of a communication link; a second transceiver communicatively coupled with a second end of the communication link and configured for communicating a signal with the first transceiver via the communication link; a first coupling/decoupling circuit configured to provide overlayed power by overlaying power from a first power source onto the signal at the first end of the communication link; and a second coupling/decoupling circuit configured to provide separated power by separating the signal from the overlayed power at the second end of the communication link, wherein the separated power is configured to power the second transceiver.

Techniques are described for determining that a property is vacant based on monitoring data collected by connected sensors and appliances near or within the property. In response to determining that a property is vacant, the condition of the vacant property can be monitored for various risks such as fire safety and security breaches. Monitoring techniques may also be used to determine when a new customer (e.g., a new tenant or property owner) has moved into the property. In response to detecting a move-in, one or more notifications may be transmitted to assist the new customer to customize a security system associated with the property. In this regard, techniques described herein may be used by service providers to improve the transition associated with move-in and move-out processes, which may also improve retention of monitoring services.

Embodiments of this application provide a fire-fighting switch device and a fire-fighting system, which are applied to the field of fire-fighting. The fire-fighting switch device includes a plurality of fire detection switch units, where the fire detection switch unit includes one or more fire detection switches, the one or more fire detection switches form at least one switch path, the fire detection switch is configured to turn on when a fire is detected, and any one of the switch paths is configured to transmit a voltage signal to a fire-extinguishing device when all of the fire detection switches on the switch path are turned on. In this solution, when a fire is detected by one fire detection switch unit, the fire-extinguishing device can be controlled to extinguish the fire provided that all fire detection switches on one switch path in the fire detection switch unit are turned on.
