Punch in your passcode into the KP-700, and you can quickly arm or disarm your Chuango security alarm system. Particularly designed for home or small office use, it works with electronic strikes/locks. The unit automatically locks the door behind you, and to re-enter, simply punch in the code and hit the disarm key. Or, you could purchase RFID tags for your colleagues or family members and keep things tight and neat in your property.
