For this reason, the detector 2 is detected by the air flowing out.
The air flow around b is affected, that is, the air in the detection area around the detection unit 2b, which should have been originally detected, is flown to the other by the air flowing out from the drain hole 5, and the detection unit 2b is detected. Detects smoke in the air flowing out from the drain hole 5. In the case where air flows out from the indoor space to the space above the ceiling, conversely to the above, the air in the detection area around the detection unit 2b is discharged from the drain hole 5 into the inside of the sensor base 1 and the sensor head 2. The air that has been sucked into the space and is located outside the detection unit 2b flows into the detection unit 2b, and the detection unit 2b detects smoke in the inflowing air.
