Be alerted when someone opens a gate or external door at your premises. • Chime or 100dB Siren • Panic Mode • Waterproof A simple and effective way to be alerted when someone opens a gate or external door at your premises. The alarm with reed switch activation mounts directly onto the frame of a door or gate. Depending on the operating mode you set, you can have it gently chime as someone enters, or set to an ear-piercing 100dB shrill until the disarm PIN is entered on the 4-digit keypad. Other features include panic mode and alarm bypass so you can pass through without setting off the alarm. Mounting screws, double-sided tape, and hook-loop tape are all provided for permanent or temporary applications. 3 x AAA batteries are required (not included).
