A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.
This cut-off switch usually detects the pilot light in one of several ways: A flame rectification device. [2] A sensor filled with mercury is used to detect the heat of the pilot light. Contraction of the mercury results in sufficient pressure to operate an electrical switch that interrupts the flow of electricity and shuts off the gas valve ...
Upright non-flued liquefied petroleum gas heater, 1970s A wall mounted gas heater that runs on either propane or natural gas. A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or ...
Local fire departments responded to an estimated average of 44,210 home structure fires caused by heating equipment, including space heaters, each year from 2016 to 2020, per the NFPA.
Fire alarm control panels are usually found in an electrical or panel room. Fire alarm systems generally use visual and audio signalization to warn the occupants of the building. Some fire alarm systems may also disable elevators, which are unsafe to use during a fire under most circumstances. [1]
A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element.
Other safety devices may be fitted in addition to an FSD. One type of these are the Vitiation Sensing Devices, [4] that detect an adequate supply of oxygen for efficient combustion, thus avoiding the production of poisonous carbon monoxide. As well as detecting a blocked supply of oxygen, these must also detect a blocked exhaust or reversed ...
Sophisticated gas sensor systems are being researched for use in medical diagnostic, monitoring, and treatment systems, well beyond their initial use in operating rooms. Gas monitors and alarms for carbon monoxide and other harmful gases are increasingly available for office and domestic use, and are becoming legally required in some jurisdictions.
