Stovetop fires are among the more prevalent of resident fire hazards and smoke detectors are among the most prevalent and economical forms of residential fire alarms. Automatic stovetop fire extinguishers can prevent property damage and even personal injury; however, these stovetop fire extinguishers may also limit smoke emissions and the subsequent detection of smoke. While an initial fire may be efficiently subdued by an automatic stovetop fire extinguisher, it is often desirable to alert present and future occupants of a fire hazardous condition. A sound based fire alarm system and method are described herein, which detects a sound burst emitted upon deployment of an automatic stovetop fire extinguisher and triggers a continuous fire alarm to alert occupants of a potentially fire hazardous condition. Alarm signals can be audible, visual, or both. The system may be a stand alone system and use battery power for affordability and ease of installation. The method described herein enables the ready and automatic extinguishment of a stovetop fire, while alerting those in the surrounding area or those in adjacent dwellings of a fire situation.

Sound based fire alarm system and method

A digital voltage detector system that is compatible with existing Armament Circuits Preload Test Sets is described. Adjustment of under and over voltage trip points is accommodated in accordance with conventional means. The digital voltage detector is compatible with all conventional Voltage Detector interface cables and adapters. Unlike the conventional voltage detector of existing Armament Circuits Preload Test Sets, over-voltage trips do not blow a fuse, eliminating the need to have replacement fuses or redundant conventional voltage detectors in an Armament Circuits Preload Test Set. Additionally, the digital voltage detector provides a digital voltage readout allowing the user to view the input voltage during a Presence of Voltage test. The digital voltage detector system facilitates timely and efficient execution of the Armament Circuits Preload Test series.

A method and system are provided, which provides reliable fire detection. In one implementation, the automated system includes a combination of sensors configured to measure various factors associated with a hazard, such as a fire or gas leakage, and generate sensor readings. Factors measured can include smoke, carbon monoxide and heat. The system further includes a detection device that is configured to determine whether a hazard or fire exists by performing a fuzzy analysis of sensor readings. The fuzzy analysis includes categorizing respective sensor readings into fuzzy sets, and determining whether the hazard exists based on a combination of the categorizations. In addition the size and direction of a fire can be determined from multiple sensors.

A stovetop fire suppression system is provided which senses the stovetop environment, assesses a fire condition, and limits a fuel or electricity heat source upon determination of a stovetop fire condition. Either, or both of, sound or heat may be monitored for the presence of a fire. Sensed day can be processed for spectral density or rate of rise for subsequent comparison to thresholds or predetermined density values. Upon determination of a stovetop fire condition a fire suppression module triggers, for example, a valve or switch to extinguish the stovetop heat source.
