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.
A fire alarm control panel (FACP), fire alarm control unit (FACU), fire indicator panel (FIP), or simply fire alarm panel is the controlling component of a fire alarm system. The panel receives information from devices designed to detect and report fires, monitors their operational integrity, and provides for automatic control of equipment, and ...
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.
The EN 54 series of standards covers the following topics and product groups related to fire detection and fire alarm systems: [6] [7] Introduction: the introduction to the series of standards contains a diagram of a fire alarm system as well as numerous definitions of terms that are used in the other parts of the series of standards.
A fire alarm annunciator panel is located where it is accessible to fire-fighting crews, such as at building entrances/exits. The annunciator panel will indicate the system status using lamps (or LEDs), an audible warning tone, and depending on the system technology, the exact location or approximate physical location of the source of a fire ...
Smoke detector mounted on a ceiling. A smoke detector is a device that senses smoke, typically as an indicator of fire.Smoke detectors/alarms are usually housed in plastic enclosures, typically shaped like a disk about 125 millimetres (5 in) in diameter and 25 millimetres (1 in) thick, but shape and size vary.
Fire detection and alarm systems are installed in premises in order to protect either life, property or both. Other objectives, such as the protection against business interruption or protection of the environment are likely to be met by the recommendations of BS 5839 Part 1. [1] BS 5839 Part 1 [1] categorises fire alarm systems as: [2]
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.
