摘要 |
This invention relates to a suction-type smoke sensing system which detects smoke with high accuracy and rapidly and identifies a fire occurrence spot quickly. The system of the present invention is provided with a piping for sucking air in each region to be inspected, a photoelectric smoke sensor which, when air in each of the regions to be inspected is sucked, senses mixing of smoke in the air, and a control unit which sucks the air in the region to be inspected and is electrically connected to the photoelectric smoke sensor so as to receive and process a detection signal. The photoelectric smoke sensor is provided with a smoke sensing portion which senses the smoke in the sucked air, a suction port provided on the air inflow side of the smoke sensing portion, directly sucks the air in the region to be inspected, and fitted with a base end portion of a suction pipe which extends to the region to be inspected, and a fitting portion provided on the air outflow side of the smoke sensing portion and fitted with the end portion of the piping. |
