Expanding knowledge: matters needing attention in purchasing smoke alarms
1. Will the smoke alarm flash a red light?
Under normal working conditions, most brands of smoke alarms have flashing lights, which means that the controller is patrolling the detector to check its working status. It flashes about every few tens of seconds. When giving an alarm, the red light flashes frequently or is always on. In addition, it should be noted that the independent smoke sensor battery will also flash red when the power is insufficient.
Second, how to turn off the smoke alarm when it keeps ringing?
1. Check whether there is smoke caused by fire at home. If yes, first rescue the fire source at home, then ventilate it, and then the smoke detector at home will automatically turn off the sound.
2. Check whether it is caused by cooking. If so, move the location of the alarm. 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 the false alarm, and the household smoke sensor will automatically turn off the sound.
3. Check whether it is affected by steam or moisture. If so, please install the alarm device away from steam and moisture to solve the problem.
When the battery is running out, it will chirp every minute. If your alarm clock sounds like this intermittently, you can replace the battery and see if it can solve the problem.
If the alarm keeps ringing, it may be that there is too much dust in the alarm, so it is time to consider replacing the alarm or cleaning it.
Third, the role of smoke alarm
At the beginning of a fire, due to insufficient combustion, articles often produce a lot of smoke. If an effective smoke detector is installed, it can detect the change of indoor smoke concentration at the first time, give a local alarm at the first time, and inform the crowd to open the fire water valve in time when the fire has not spread, so as to control the fire in time at the early stage of the fire and stifle the danger in the cradle.
