After receving electronic impulses from the detectors or MCP it declares the emergency state of fire by sounding the hooters.
Principle : It consists of three main parts - the transmitter, which project a modulated infra-red light, the receiver, which registers the light and produces an electrical signal and the interface, which processes the signal and generates alarm or fault signals.
Principle : The transmitter and receiver are designed to be fitted on opposite walls approximately 30 to 60 cm below the ceiling, to protect an area upto 100m long and 15m wide, a total of 1500 m2.
Applications : It has been designed to protect large open spaces such as museums, churches, warehouses, factories, shopping malls etc.
Principle : An infrared sensor, designed to detect specific types of flames, making it immune to solar radiation and other nuisance sources of infrared. It is sensitive to low-frequency, flickering infra-red radiation, emitted by flames during combustion.
Applications : It is designed for use in large areas that require a detector to give a fast response in potentially dusty or highly flammable environments, such as textile factories, aircraft hangars etc.
Battery Operated Detector
Applications : It is operated on battery, meant for use in small areas like home, small offices, workshops etc.
