St. Charles, IL - System Sensor today announced the inclusion of the ETL Listed Mark to its i3 line of smoke detectors. The ETL Listed Mark, the fastest growing safety certification mark in North America, verifies that i3 products meet the minimum requirements of widely accepted product safety standards, and that System Sensor has agreed to periodic follow-up inspections to verify continued compliance.
