Every person, firm or corporation maintaining an alarm system described in this chapter shall either post on the premises of the alarm system or file with the police department a notice containing the names and telephone numbers of the persons to be notified in case of emergency or alarm activation or to render service to the system during any hour of the day or night. The persons named shall include the occupant of the premises, or the alarm business or agents responsible for the maintenance of the system. If posted, such notice shall be placed near the front door of the structure containing the alarm system or at the front gate if the structure is fenced; and the notice shall be posted in such a position as to be clearly legible from the ground level adjacent to the structure or fence. It shall be the duty of the alarm user to maintain current such a notice whether posted or filed with the police department. (Ord. 2457 § 1, 2000)
