I purchased this alarm for my sliding door. It works so well - very loud! My grandchildren are between the ages of 2yrs - 7yrs. We have an inground pool in our backyard. This alarm gives us a peice of mind, although we are still very protective of/watch the kids closely when they come over. Thank you, Katherine Soulliere

This uses AAA batteries. they are easier to change when mounted than watch batteries which is why I bought them. You can have one remote control several or have up to eight remotes control one. Choice between doorbell noise or loud alarm (or off or panic mode). Alarm is loud and runs for 30 seconds even if you shut the door again, pauses for 15 seconds and will reset if the door is shut or sound again if it is not. Can be shut off with the remote. If a remote is not pared with that particular alarm, it will not work, so you can't just buy a remote and shut off someone's alarms Remote Control Code Pairing The main unit and the remote control have been coded-pairing at the factory, so the remote control can be used without any setting by yourself. How to enter the code pairing state: Press the [UNLOCK] disarm key of the remote control to enter the disarm mode, press and hold the [BELL] code pairing key for 10s (ignore the bell/- chime sound from the main unit), and release it when you hear a “Bi” sound from the main unit. Then the main unit has entered the code pairing state. Pairing the second remote or more remotes: After the main unit has entered the code pairing state, immediately press the arm or disarm key of the un-coded remote control [UNLOCK/LOCK], the main unit will emit two “Bi Bi” sounds to indicate successful pairing. Using this method, one main unit can code up to 8 remote controls. Delete all pairs of codes: After entering the code pairing state by referring to the method in 5.5.1, immediately press the emergency key of the remote control [LIGHTNING BOLT], the main unit will emit a ‘Bi’ sound, and all the remote controllers connected to the main unit will be deleted from the code pairing information. * - THIS DELETES ALL REMOTES INCLUDING THE ONE I WAS USING - * How to code the first remote control: take out the batteries of the main unit, re-install the batteries after 2 minutes, press and hold down the [BELL] code key within 2s after you hear the ‘Bi’ sound from the main unit, * - AND KEEP IT PRESSED - * the the main unit will emit the ‘Bi’ sound after about 10s, at this time, release the code key, and then press the arm or disarm key, the main unit will emit 2 “Bi Bi” to indicate the success of the code pairing. i HAD PROBLEMS FOLLOWING INSTRUCTIONS

Laut und schnell anzubringen. Ich fühle mich mit diesem Gerät sicherer, und wenn ich arbeiten bin, brauche ich mir auch in der dunklen Jahreszeit keine Gedanken machen, der laute Ton würde das ganze Haus wecken und jeden Einbruchsversuch zunichtemachen.
