Answer This Question

A:  You will use the double-sided tape to mount the alarm and magnetic sensor on the door or window to be protected, placing one of the units on the part of the fixture which opens and the other on the stationary part of the fixture frame.

              We put ours on the front door and sliding glass door to alarm us if our young kids try to go outside. We have to switch off the alarm every time we let the dog out and the double sided tape did not work well on the front door but it works well.

              Early to install and to use. Loud enough for you to hear, if it's to loud for you just put a piece of masking tape over the speaker. Great product.

              These are mounted on the front and back door. They are very loud with two different alarms for notifying you if someone enters or exits as you would hear in a business or an alarm if someone opens the doors in the middle of the night. Battery cover must be removed to turn on/off the alarm.

              Small but screaming loud
              These are small units but they make up for small size by being ear piercing. Installed using 2 way tape. Super easy. Well worth the money.
