Mellissa Hodgetts and Edward Lubic are the heart of the false alarm reduction group. Together, they have over 35 years combined experience. They monitor all accounts for early signs of trouble, working with our monitoring center and service department to eliminate false alarms. ADS has one of the lowest false alarm occurrence rates in the industry.
