Properly handle the property with smoke alarm in the owner's home.

1, cooking, solution: move the alarm clock. Installing the alarm in a place far away from cooking will make the smoke generated by cooking become very thin when it reaches the alarm, thus reducing false alarms. Choose to buy photoelectric smoke detectors. The photoelectric alarm is not sensitive to tiny smoke particles, so it will not give a false alarm to smoke particles produced by cooking.

2, the influence of steam or moisture, solution: install the alarm device in a place far away from steam and moisture, such as the bathroom corridor is not suitable for installing an alarm, so the problem can be solved. But if the alarm works normally, but now it reacts to steam or moisture, then the problem may be the cause of the alarm aging.

3. The old alarm will become more sensitive and easier to respond to steam and moisture. Therefore, the false alarm may also be that the alarm has exceeded its service life and needs to be replaced.

4. Smoke generated by cigarettes, solution: In general, unless the smoke generated is very thick, the smoke detector will not respond to cigarette smoke. For example, many smokers smoking in the same room may cause an alarm. If the alarm is too old, it will respond even if the smoke concentration is very low. So in turn, we can also judge whether the alarm is aging.

What is the principle of smoke alarm in new house?

1. The infrared beam of the infrared emission tube is scattered by smoke particles, and the intensity of the scattered light is directly proportional to the concentration of smoke, so the intensity of the infrared beam received by the photosensitive tube will change, and it will be converted into a point signal and finally into an alarm signal.

2. The smoke sensing of the alarm is mainly completed by the optical maze, and there is a set of infrared emitting and receiving photocells in the maze with the diagonal angle of 135 degrees. When there is no smoke in the environment, the receiving tube can't receive the infrared light emitted by the infrared emitting tube, and the subsequent sampling circuit has no electric signal change.

3. When there is smoke in the environment, the smoke particles enter the maze to scatter the infrared light emitted by the emission tube. There is a linear relationship between the intensity of scattered infrared light and smoke concentration, and the subsequent sampling circuit changes. The main control chip inside the alarm determines whether there is a fire alarm. Once the fire alarm is confirmed, the alarm sends out a fire alarm signal, the fire indicator (red) lights up, and the buzzer starts the alarm.
