Methods, devices, and systems for a universal pipe sleeve junction for an aspirated smoke detection system are described herein. In some examples, one or more embodiments include a sleeve body having an outer surface and an inner surface, the inner surface defining an opening through the sleeve body, wherein the sleeve body further includes a first end surface and a second end surface opposite the first end surface, and a nozzle having an outer surface and an inner surface, the inner surface of the nozzle defining an opening through the nozzle and extending through to the inner surface of the sleeve body, where the nozzle opening is configured to couple with a pipe sleeve attachment mechanism.

A fire detection device includes a vented detector housing, with an opening defined in a mounting base. A substance exhaust channel in air flow communication with the opening extends upward from the mounting base. A pressure release turbine includes an impeller operatively disposed in the channel. A rotation sensor senses rotation of the impeller and generates an alert upon detection of a heat level indicated by rotation of the turbine rotor at a predetermined speed. A high pressure and/or heat louver disposed over the opening opens in response to a predetermined heat level. An actuator detects opening of the louver and generates an alert. A thermostatic device disposed in the housing senses, and generates an alert at, a predetermined heat level. A thermal imaging device disposed in the housing senses, and generates an alert at, a predetermined heat level.

A charging base, including a charging circuit, a power supply circuit and a control unit; where the control unit is electrically connected to the charging circuit and the power supply circuit; when a charging voltage or a charging current of the charging circuit exceeds a preset threshold, the control unit controls a connecting line on the charging base to connect to a ground to form a short circuit and be disconnected from an external charging power supply, and controls a charging mode of the charging circuit to switch to a power supply mode of the power supply circuit for supplying power to a safety reminder unit provided on the charging base. The solution in the embodiments can turn off the power output in time and provide a safety alarm when the hardware circuit of the charger fails.

The present invention relates to a hazardous material measuring apparatus capable of analyzing concentration and components of various hazardous materials. The hazardous material measuring apparatus analyzes an optical spectrum obtained by a spectrometer or a hyperspectral image obtained by a hyperspectral camera, thereby analyzing concentration and components of the hazardous materials to be measured.

One or more aspects of the present application relate to systems and methods for collecting, processing and generating information regarding risk assessments related to fire events. More specifically, one or more aspects of the present application relate to processing of inputs to generate assessments corresponding to a characterization of risk for individual structures within a defined region. Other aspects of the present application relate to processing of inputs to generate assessments corresponding to a modeling or characterization of fire behavior risk within a defined region. Such assessments of structural risk or fire behavior risk can be utilized in accordance with fire mitigation or personnel organization response to structural risk or fire behavior risk.

In accordance with various aspects of the present disclosure, methods and systems for fire detection are disclosed. In some embodiments, a method for fire detection includes: acquiring data related to a monitored area, wherein the data comprises image data related to the monitored area; determining, based on the acquired data, whether a first mode or a second mode is to be executed for fire detection, wherein the first mode comprises a first smoke detection, and the second mode comprises a first flame detection; and executing, by a hardware processor, at least one of the first mode or the second mode based on a result of the determination.

A wireless sensor alert system capable of detecting an abnormal condition, such as one of smoke, fire, carbon monoxide, temperature deviation, humidity, air quality, and radon levels. The system provides remote notifications and status information regarding the monitored information in the environment of a detector. The alert system additionally communicates over communications networks to provide user and authorized third party interactivity, as well as real-time sensor network data based upon customizable triggering events and conditions.

A system performs cloud-based fire protection. The system receives, by a cloud platform, data from one or more initiating devices. The system stores the data in a persistent data storage of the cloud platform over a period of time. The system applies machine learning to the data to build or adjust a predictive detection model. The system processes, by computing resources of the cloud platform, the data using the predictive detection model to determine an existence of a safety event. The system then transmits, to at least one notification device, an event notification in response to the existence of the safety event.

A system and method for object location notification in a fire alarm system is disclosed. The fire alarm system includes a fire alarm panel and fire alarm devices deployed within a premises that capture audio and/or image information. The fire alarm panel generates alarm signals and provides notifications of the existence of objects of interest from the audio and/or image information captured by the fire alarm devices. In examples, the fire alarm devices include alarm notification devices that generate an audible and/or visible fire alarm to occupants of the premises such as sirens and strobe lights, and fire sensor devices such as flame sensor devices and smoke sensor devices that monitor for flame and smoke as the indications of fire, respectively. In one embodiment, an analytics system is integrated within the fire alarm devices that determines the existence of the objects of interest from the captured audio and/or image information.
