This colorful keypad has four preset patterns for the combinations, but they can be changed. (contact us after purchase to provide a custom code)
4 different consecutive patterns are needed to solve.
Every time a correct code is entered a dry contact relay is triggered ( four unique relays), and the next code is ready to be inputted.
The lights on the bottom will pulse when the pattern needs to be typed in and when the code is correct, the light will stay solid, then move on to the next pulsing light.
