A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible or visual alarm from the detector itself.
A manual call point is an active fire protection device, usually wall-mounted, that, when activated, initiates an alarm on a fire alarm system.
In its simplest form, the user activates the alarm by pushing the element, which completes a circuit and locks the element in the activated position, sending an alarm to the fire alarm control panel.
An air-sampling smoke detector is capable of detecting microscopic particles of smoke. Most air-sampling detectors are aspirating smoke detectors, which work by actively drawing air through a network of small-bore pipes laid out above or below a ceiling in parallel runs covering a protected area.
Small holes drilled into each pipe form a matrix of sampling points, providing an even distribution across the pipe network. Air samples are drawn past a sensitive optical device, often a solid-state laser, tuned to detect the extremely small particles of combustion. Air-sampling detectors may be used to trigger an automatic fire response, such as a gaseous fire suppression system, in high-value or mission-critical areas, such as archives or computer server rooms
An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire.
They are used to detect fires in buildings where standard point smoke
detectors would either be uneconomical or restricted for use by the height of the building.
A fire alarm notification device is an active fire protection component.
A notification appliance may use audible, visible, or other stimuli to alert the occupants of a fire or other emergency condition requiring action.
Wall or floor mounted electromagnets controlled by a fire alarm system that magnetically secures spring-loaded self-closing smoke tight doors in the open position.
