If one of them falls off, you can turn off the switch and the alarm will stop. The switch will only work when it is on.

@@ankoshunan1397 what if I am not at home for few days and one of the unit falls, it will keep on ringing and disturb the neighbours, that is my main concern. Adhesive may be strong but you can't neglect the worst case scenario

As long as you turn off the switch, the alarm sound will stop. You can also turn off the switch when you don't want it to alarm, so that it will not alarm.

Thanks for the support

It is good to have because it does alert you that somebody just came in your home that maybe you weren't expecting

This product is installed in the door. To open or close the switch,you have to enter the house to operate

Yes, the alarm will stop when the switch is turned off, but it is usually installed inside the door, the door must be opened before the switch can be turned off, and the alarm will sound as long as the door is opened@aytacprkz7142

The point is...that it makes an alarm go off and gives a warning for the owner of the house to reach the Pew Pew 🔫 It's not a lock but an alarm silly kid.. What is so funny?.This is exactly what I'm looking for.
