A fire alarm system is an electronic device designed to alert people from visual and audio alarms when smoke/fire is present. These alarms may be activated from smoke detectors, heat detectors, or from a fire alarm pull station.
Initiating devices are :
Manually actuated devices; also known as fire alarm boxes, manual pull stations, or simply pull stations, Break glass stations, call points or Buttons. Devices for manual fire alarm activation, are installed to be readily located (near the exits), identified, and operated.
Automatically actuated devices can take many forms intended to respond to any number of detectable physical changes associated with fire: convected thermal energy; heat detector, products of combustion; smoke detector, radiant energy; flame detector, combustion gasses; fire gas detector, and release of extinguishing agents; water-flow detector. The newest innovations can use cameras and computer algorithms to analyze the visible effects of fire and movement in applications inappropriate for or hostile to other detection methods.
Conventional Main Panel is the hub of the system, monitors inputs and system integrity, controls outputs and relays information and positioned in loops throughout a building.
Manual Call Point is an active fire protection device that usually gets activated when the user pulls the handle down or press the keys.
Response Indicator Are used for pinpointing the location of detector in alarm condition. These remote indicators comes handy when these detectors are installed' in closed cabins or above false ceiling and floor voids.
Conventional Smoke / Heat Detector is used to warn about fire hazards in case fire is detected on the premises where they
Hooter cum strobe will give the audible & visible indication to the users.
