fire or of external causes beyond the control of the owner or person in possession
that may have caused the alarm, the activation shall be presumed to be a false
alarm. Not included as a false alarm will be those activations caused by
earthquakes or other phenomena beyond the control of the owner or person in
possession.

have the right to appeal said assessment to the Fire Chief within ten (10) calendar
days of his receipt of the notice of assessment. The Fire Chief is authorized to
excuse the assessment if he determines that a false alarm as defined, did not
