Merlin Beam Sensor
Safety beam sensor set only suitable for the Prolift 230 and Prolift 430 garage door openers.
We highly recommend the use of safety beam sensors.
Properly working "safety beams" offer an added safety guard. Safety beams are connected to the bottom of the track and reverse the door when an infrared beam is broken. Safety is improved because nothing actually has to make contact with the door before it reverses. Consider adding a Safety beam as an extra measure of safety to prevent against entrapment.
