No alarm user shall activate any new alarm system installed after the effective date of this ordinance, in any unincorporated area of Mendocino County, without registering that alarm system with the Sheriff at least 24 hours before the system is activated. Alarm systems installed in emergency situations for temporary use not to exceed thirty days may be registered at any time prior to activation.
The alarm user who registers the alarm system shall provide the following information to the Sheriff in writing:
The name, address and telephone number of the response alarm system user.
Name, address and telephone number of the alarm business installing the alarm (if any).
A description of the premises or area protected by the response alarm system including the location of doors, windows and areas protected by the alarm system within the premises.

The name, address and telephone number of the place of business where the alarm terminates.
The alarm user shall notify the Sheriff in writing within ten (10) days of any changes in registration information.
Alarm users of alarm systems installed prior to the enactment of this ordinance which are not registered with the Sheriff, shall have ten (10) days in which to register their alarm system after notification of the registration requirement by the Sheriff.
Failure of any alarm user to register any alarm system as set forth herein shall also be grounds for non-response by the Sheriff to any signal from that alarm system, until the alarm system is registered.

Sec. 8.60.040 - False Alarm Regulations.¶
Public safety and safety of peace officers require that any alarm system causing false alarms be corrected immediately.
After the first false alarm response in any calendar month, the Sheriff may notify the alarm system user of the violation and consequences of action by the Sheriff as set forth in this ordinance. That notification by the Sheriff may require written proof be furnished to the Sheriff within ten (10) days by the alarm user that the problem causing the false alarms has been corrected.
Failure to provide proof of correction within that ten day period may be grounds, at the discretion of the Sheriff, for non-response to a signal from that alarm system until proof of correction is received from the alarm user.
The second false alarm in a calendar month, or the third false alarm in a calendar quarter and subsequent false alarms in that month or quarter shall be cause for the County of Mendocino to bill the alarm user for the costs incurred by the Sheriff responding to that false alarm. The amount of those costs billed shall be $150.00 (one hundred fifty-dollars) per false alarm. Failure to pay may be grounds for non-response to that alarm by the Sheriff.
After the fourth false alarm response to an alarm system by the Sheriff in a calendar quarter, the Sheriff will notify in writing the alarm user to show cause why response to the response alarm system causing the nuisance false alarms should not be terminated. The Sheriff shall make the determination whether or not response shall be terminated.
If response to an alarm is terminated, it shall be for a period not to exceed sixty (60) days from the date the alarm user is notified of non-response by the Sheriff, or until satisfactory proof of correction of the problem causing the false alarms is furnished to the Sheriff, whichever is shorter.
In any case where the Sheriff terminates response to an alarm system under this ordinance, the alarm user shall be notified of the termination prior to the actual termination of response.
For the purposes of this ordinance, any number of false alarms in a time period from 12:00 p.m. of one day to 12:00 p.m. of the following day shall be considered one (1) false alarm.
In any case where response to an alarm system is terminated, it will be the responsibility of the alarm user to apply to the Sheriff at the end of the non-response period for response to that alarm system.
