Irregular cleaning of wireless smoke alarms

Wireless smoke alarms have small screen-like covers around the sensing center to prevent outside bugs and dust from entering the sensing center. However, dust can accumulate around the shelter and delay the movement of the air. Cleaning the alarm is a relatively easy thing. Just use a vacuum cleaner to suck the air out of the alarm and clean it at least once a year.

The battery of the wireless smoke alarm can be used at least for one year under normal conditions. The reason for the wireless smoke alarm being suspended is due to manual removal of the battery, perhaps for weak electrical signals or to stop false alarms, and then forgetting to put them on.

The wireless smoke alarm has added a spring switch and it is impossible to replace the smoke detector with a ceiling without a battery. A key improvement. A battery with a lifespan of 10 years is installed in the smoke alarm to reduce the probability of battery renewal. Lithium-ion battery can be used. However, it still needs to be tested regularly.

The working principle of the wireless smoke detector : 1. The infrared beam of the infrared emitting tube is scattered by the soot particles, and the scattered light intensity is proportional to the smoke concentration. 2. The intensity of the infrared beam received by the photodiode will change, and it will be converted into a point signal and finally converted into an alarm signal.
