    smoke alarm

    Smoke alarm is a very important safety device that can issue an alarm in a timely manner when a fire occurs, reminding people to take appropriate measures. However, if maintenance and battery replacement are not taken seriously, smoke alarms may also become a potential danger. If the battery level is low, the smoke alarm may not function properly, thereby delaying the detection and handling of fires.

Therefore, it is recommended to check the battery of the smoke alarm at least once a year and replace it if necessary. In addition, smoke alarms should be regularly tested to ensure they are functioning properly and in good working condition.
