There are several methods being implemented to meet the requirement for monitoring safety devices and each manufacturer is free to design its own system. As manufacturers submit their operators to UL for approval, they will specify which components will be listed with their operators.
EMX designed the IRB-MON to comply with all the known monitoring methods and will be adding any additional new methods as they become available.
EMX recommends that you check with your gate operator manufacturers to confirm that they will be listing the IRB-MON as an approved component with their equipment.
