Continued false alarms generated from the same location within the same one-year period shall also be assessed a fee set by resolution for each successive false alarm.
(b)Notwithstanding Subsection (a), whenever the Fire Department is required to respond to a false alarm while the system is being repaired or otherwise modified, and the person performing the work has failed to notify the Fire D epartment in advance that such work 15 was being done, the persons pe rforming the work shall also be assessed a fee set by resolution for each such occurrence.
(c)For purposes of this Section, "false alar m" shall mean the activation of any local or central station alarm because of malfunction, including, but not limited to, mechanical or electrical defects, water surges, or because of improper installation, operation testing or maintenance of such system. Whenever the Fire Department responds to the location of a false alarm and finds that there is no evidenc e of a fire or of external causes beyond the control of the owner or person in po ssession that may have caused the alarm, the activation shall be presumed to be a false al arm.
