Aspirating Smoke Detection Systems

Abstract

The invention provides an air-breathing smoke detection system which can quickly detect smoke with high precision and determine the location of a fire at the same time. The suction type smoke detection system includes: piping for sucking air in each inspection target area; a photoelectric smoke detector for detecting smoke mixed in the air when sucking in the air in each inspection target area; and a control unit, It sucks the air in the area to be inspected, and is electrically connected to the above-mentioned photoelectric smoke detector to receive and process the detection signal. Wherein, the above-mentioned photoelectric smoke detector includes: a smoke detection part for detecting the smoke in the inhaled air; an air suction port, which is arranged on the air inflow side of the smoke detection part, directly sucks the air of the above-mentioned inspection object area, and, The suction port is engaged with the proximal end of the suction pipe extending to the area to be inspected; and the fitting port is provided on the air outflow side of the smoke detection unit and fitted with the end of the pipe.

Description

technical field [0001] The present invention relates to an inhalation type smoke detection system which inhales air in an area to be inspected and detects smoke while inhaling the air. Background technique [0002] The aspirating smoke detection system is a system that installs piping in the inspection target area, sucks in the air in the inspection target area, and detects the smoke mixed in the air. There is Japanese Patent Document 1 as an example of this suction type smoke detection system. The system of this Japanese Patent Document 1 will be briefly described below. [0003] The system includes an air sampling pipe drilled through a plurality of suction holes and laid in a network, an air suction device connected to the air sampling pipe and sucking air into the air sampling pipe, and distributed inside the air sampling pipe A plurality of smoke detectors and a display device that receives and displays a detection signal from any one of the above smoke detectors. ...

AI Technical Summary

Problems solved by technology

[0009] If the area to be inspected is large and the suction hole of the air sampling pipe is far away from the smoke detector, it will take a long time to detect the smoke and it will be difficult to detect the fire early

[0010] In addition, it is difficult to detect smoke with high precision if the amount of smoke generated by the fire is small and it is a special inspection target area.
