UL325 Compliance

Understanding the 2018 Regulations for UL325 Compliance

  • Effective August 1, 2018
  • A resistor required for monitoring must be permanently installed by the manufacturer. (Separate components are no longer acceptable.)
  • Each entrapment zone requires two means of protection — either two external sensors, two inherent means or one external and one inherent. (Previously each gate operator had to have two means of protection.)
  • Refer to DASMA’s technical data sheet and summary article for additional UL325 compliance information.
