Smoke detector is a device that uses photoelectric principle, ionization principle, thermistor principle and other technologies to detect the concentration of smoke in the air. When a fire occurs, smoke detectors can quickly detect smoke and send alarms to remind people to escape in time.
How to operate:
1. Installation location: Smoke detectors should be installed in the center of the ceiling of the room, away from doors, windows and vents to ensure that they can detect smoke in time when a fire occurs.
2. Power access: Connect the smoke detector to the mains or backup power supply to ensure that it can work properly. 3. Test: Regularly test whether the smoke detector is working properly, such as pressing the test button. If the device can make a sound, it means it is working properly.
