Detector generates a SPRK when its ctype element is nearby. To set its ctype, draw over it with an element like you would with CLNE. Make sure you don't accidentally set its ctype when drawing the wires around it. DTEC is a replacement for detector wall so that you can make your creations smaller.

You can set the tmp2 to determine the detection radius (in the shape of a square)
