An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1] The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.
Residential smoke alarms are usually powered with a 9-volt battery, or by mains electricity. Some smoke alarms use a combination of the 2; usually using the 9V battery as an extra power source in the event of an outage. Commercial smoke detectors issue a signal to a fire alarm control panel as part of a fire alarm system. Usually, an individual ...
An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, [1] typically as an indicator of fire. [2] They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical [3] or restricted for use by the height of the building. Optical beam smoke ...
For smoke detectors according to EN 54-7 and fire detectors with smoke sensor (parts 12, 20 and 30 of EN 54) the test fires TF2, TF3, TF4 and TF5 are used. The EN 54-20 defines the following test fires with reduced fuel quantity for aspirating smoke detectors with enhanced or very high sensitivity (class A or B):
A fire alarm system is a building system designed to detect, alert occupants, and alert emergency forces of the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. Fire alarm systems are required in most commercial buildings.
In dwellings, smoke detectors are often stand-alone devices. In non-domestic buildings, fire detection will typically take the form of a fire alarm system, incorporating one or more of the following automatic devices: Heat detector; Smoke detector; Flame detector; Fire gas detector
In most cases, once the alarm has been triggered by fire or smoke, a loud sound emanates to warn of danger or a message notifies the local fire department. Smoke alarms, also known as smoke detectors, generally sound an audible and visual alarm. Smoke alarms are usually housed in a disk-shaped plastic enclosure about 6 inches in diameter and 1 ...
