Alarm monitors which have service agreements with alarm users shall be responsible for compliance by such users with the terms and provisions of this chapter, and notices requiring compliance or notices of revocation for user violations of this chapter shall be given to the alarm monitors. Alarm monitors receiving notices to comply or notices of revocation shall either comply with such notices or terminate the contracts with the noncomplying users. A failure on the part of an alarm monitor to comply with this section shall be a violation of this chapter, and the continuation of such violation after the mailing or delivery of a 30-day written notice to the alarm monitor shall be sufficient cause for the police department to cease taking messages or communications from such monitor. (Ord. 1608 § 6, 1980)
