Smoke module wiring instructions
Black: power ground
Red: positive power supply DC9V
White: relay Normally open
Blue: relay common terminal
Green: relay normally closed terminal
Simple test method:
1, press and hold the test button 3S LED starts blinking, relay the aggregate relay working with common terminal is turned on.
2 smoking cigarettes, the smoke is blown into the maze 3S about light starts blinking, the relay, the relay switched often beginning with the common terminal
