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.
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.
The standard details requirements for a range of alarm systems including central station burglar alarms, police station connected alarms, local alarms, proprietary systems, holdup alarms, and digital alarm communicator system units. It also covers power supplies essential for burglar-alarm equipment operation.
The term "fire detection and fire alarm systems" is a fairly wide definition, including small systems whose field devices consist only of sounders and manual call points, to complex networked systems with a large number of automatic fire detectors, manual call points and sounders, connected to numerous networked control and indicating panels.
Fire alarm systems are required in most commercial buildings. They may include smoke detectors, heat detectors, and manual fire alarm activation devices (pull stations). All components of a fire alarm system are connected to a fire alarm control panel. Fire alarm control panels are usually found in an electrical or panel room.
The NFPA 72 "covers the application, installation, location, performance, inspection, testing, and maintenance of fire alarm systems, supervising station alarm systems, public emergency alarm reporting systems, fire warning equipment and emergency communications systems (ECS), and their components."
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.
In a conventional system, smoke detectors are typically wired together in each zone and a single fire alarm control panel usually monitors several zones which can be arranged to correspond to different areas of a building. [56] In the event of a fire, the control panel can identify which zone or zones contain the detector or detectors in alarm.
