Failure to obtain a required Alarm Permit may result in municipal fines or refusal by an emergency agency to respond to an alarm at your premises. To find out if a permit is required in your area, contact your local Police, Sheriff or Fire Department using their non-emergency telephone number, or look them up on the Internet.
