SANDY SPRINGS, Ga. — Time has run out for several alarm companies operating in Sandy Springs to pay the city thousands of dollars in fines.

Last week, 39 companies were notified they were 90 days past the due date to pay fines related to false alarms.

The city said it had received more than 11,000 false alarm calls in 2016, costing more than $775,000.

April 11 was the deadline for the companies to pay up, and now, the city said it will stop responding to those which have not paid.

On Thursday, the city sent out a list of 21 companies it said still aren't compliant. They include:

  • Alarm Force
  • Banner Security
  • Consumer Security
  • Convergint Technologies
  • Ede System
  • Interlink
  • Live Watch
  • New Georgia
  • Nationwide Integrators
  • Nichols Security
  • Owen Security
  • Patterson Security
  • Protection Concepts
  • Rock solid Security
  • RTA Security
  • Safe Home Security
  • Safecom Security
  • Security Cen
  • Security Sal.
  • Simplex Grinnell
  • Strong Security

Two companies countered, however, and filed a federal lawsuit calling the false alarm ordinance "unconstitutional."
