Alarm systems shouldn't limit you to using a single entrance to your home. By installing a wireless Keypad Control for AAA+ at your back door or garage entry, you'll be able to enter and leave your home from any door you like, arming the AAA+ Home Smart Center security system as usual. The AAA+ Home Smart Center is sold separately. This Keypad Control can also be used to arm and disarm the Audio Alarm for AAA+ (sold separately). # Keypad # 2 lithium 3-volt batteries # Mounting hardware # Mounting template # Instructions
