Smoke alarms are often hung on the ceiling and are prone to failure over time, so they need to be simulated for alarm detection on a regular basis. The installation height of the existing power distribution room is 6 meters, and it is difficult for inspection personnel to hold an external smoke source to simulate the smoke alarm; some use smoke guns close to the smoke alarm, but the size of the smoke gun is too long and the tester is unstable when held in hand, and it is easy to hit the live equipment, posing a safety hazard; the flow direction of the handheld smoke source is unstable, so the detection data is inaccurate, and it is easy to misjudge or miss.
