摘要
An early electrical fire sensing system for a high voltage panel, a low voltage panel, a motor control panel, a distribution board, or a power distribution panel comprises the first laser that emits the frequency beam absorbed by benzyl alcohol gas and the first detecting device which detects the first beam intensity; the second laser which emits the frequency beam absorbed by BHT gas and the second detecting device which detects the second laser beam intensity; and a main control unit which consists of a microprocessor. The main control unit gives a fire alarm event when the first laser beam intensity of the first detecting device is decreased more than a reference value, while a fire emergent alarm event when the second laser beam intensity of the second detecting device is decreased more than a reference value.
