A fire alarm system has a number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present.
Equipment specifically manufactured for these purposes is selected and standardized installation methods are anticipated during the design. EN 54 is a mandatory standard for fire detection and fire alarm systems in the European Union, aiming to establish harmonized technical standards against which products in the field should be benchmarked and certified by a qualified testing house known as a Notified Body. This component, the hub of the system, monitors inputs and system integrity, controls outputs and relays information. Primary power supply: Commonly the non-switched 120 or 240-volt alternating current source supplied from a commercial power utility. In non-residential applications, a branch circuit is dedicated to the fire alarm system and its constituents.
Dedicated branch circuits” should not be confused with “Individual branch circuits” which supply energy to a single appliance. This component, commonly consisting of sealed lead-acid storage batteries or other emergency sources including generators, is used to supply energy in the event of a primary power failure. The batteries can be either inside the bottom of the panel or inside a separate battery box installed near the panel. Initiating devices: These components act as inputs to the fire alarm control unit and are either manually or automatically activated.
Examples would be devices such as pull stations, heat detectors, and smoke detectors. Heat and smoke detectors have different categories of both kinds. Some categories are beam, photoelectric, ionization, aspiration, and duct. Notification appliances: This component uses energy supplied from the fire alarm system or other stored energy source, to inform the proximate persons of the need to take action, usually to evacuate. This is done by means of a pulsing incandescent light, flashing strobe light, electromechanical horn, electronic horn, chime, bell, speaker, or a combination of these devices. Building safety interfaces: This interface allows the fire alarm system to control aspects of the built environment and to prepare the building for fire, and to control the spread of smoke fumes and fire by influencing air movement, lighting, process control, human transport and exit.
In the United States, fire alarm evacuation signals generally consist of a standardized audible tone, with visual notification in all public and common use areas. Emergency signals are intended to be distinct and understandable to avoid confusion with other signals. Temporal Code 3 is the standard audible notification in a modern system. Voice Evacuation is the second most common audible in a modern system. Legacy systems, typically found in older schools and building have used continuous tones alongside other audible schema. High-reliability speakers are used to notify the occupants of the need for action in connection with a fire or other emergency. These speakers are employed in large facilities where general undirected evacuation is considered impracticable or undesirable.
