I purchased the kit MK125. Mounted works well but interrupting the beam of light that illuminates the photoresistor circuit employs a 7/2 to energize the relay and lighting up again the photoresistor employs 7/2 back in stand-by. How can 'get an immediate response without having to wait 7 seconds?
Thanks
