Schematic of a permanent magnet motor using brushes and magnets in the stator. A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with ...
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
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.
Such systems typically operate a similar structure to a standard wired fire alarm network, in that Manual Call Points may be mixed with automatic fire detection in the form of heat detection and smoke detection (often specially designed to be dust resistant, due to the increased likelihood of dust on a construction site) and can be connected to ...
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 ...
Active fire protection (AFP) is an integral part of fire protection. AFP is characterized by items and/or systems , which require a certain amount of motion and response in order to work, contrary to passive fire protection .
Suitably qualified and experienced fire protection engineers may qualify for registration as a professional engineer. The recognition of fire protection engineering as a separate discipline varies from state to state in the United States. [24] NCEES recognizes Fire Protection Engineering as a separate discipline and offers a PE exam subject. [25]
