Digital Code Lock

Last Friday a Digital Code Lock arrived. I want to see if i can do something useful with it. It is intended for use with a door opener.
Above the keypad there are 3 LEDs of which 2 are freely usable; the 3rd (middle) bi-color LED shows the status of the code lock.  The code lock comes with a manual with description of all connections and some connection examples.

It’s one of the cheaper code locks, but if all goes well and i’m satisfied i might buy another more eye-catching one.

This model has a sabotage switch inside just like the tamper switch on the inside of Visonic sensors. I’m going to connect this switch to a Visonic MCT302 aux input located inside my house and any attempt to sabotage the code lock will fire the alarm. One of the freely usable LEDs is going to display the status of the alarm, the other free LED doesn’t have a function assigned yet. Just a matter of time…

The Code Lock will be supervised by an Arduino so i can make full use of all the functionality it has to offer.
