Here are two instructional videos that will make your boundary kit functional. You will note that your alarm matches the second one shown in the video. It is smaller and simpler to use. Merely mount the alarm on the wall, horizontally and stretch the thread to span the area you wish to block. Place the boundary rope underneath the thread. The alarm has a three-position switch on the underside. To the left is a ding-dong sound. In the middle is ‘Off’. Move the switch to the right to arm the alarm. To turn the system off, simply move the switch to the middle. Then you can move the magnet to the ground and remove the rope. To set it up again, merely reverse the sequence.
