On the Subject of Blacks and Whites

We’ve all dreamt of a module that could do this. Now, it’s here.

Note: A Black will always have a White on the opposite side of the bomb and vice versa, unless somehow restricted.

Each Black will be paired with one White and vice versa. There may be markings to disambiguate pairings. Both modules will always activate simultaneously.

When they activate, White’s grid of 9 lights will activate in a specific pattern. Press Black’s four buttons correspondingly to temporarily disarm them. Each button must be pressed a number of times equal to the number of lit lights in the same quadrant on white’s grid. The middle five lights are in more than one quadrant.

Pressing a button too many times or allowing the timer to run out will incur one strike and temporarily disarm both modules.
