Test a non-supervised alarm system every two months. Use a different actuation device in each test of a multi-actuation device system so that no individual device is used for two consecutive tests. After each test, quickly restore the system to its normal operating condition.

Maintain or replace power supplies as often as necessary to assure a fully operational condition. Back-up means of alarm, such as employee runners or telephones, must be provided when systems are out of service.

If the alarm circuitry is installed after January 1, 1981, and is capable of being supervised, supervise it and provide positive notification to assigned personnel whenever a deficiency exists in the system. Make sure that all supervised alarm systems are tested at least annually for reliability and adequacy.

Confirm that the person servicing, maintaining, and testing the system is trained in the designed operation and functions necessary for reliable and safe operation of the system.
