  (4) fire detection and alarm systems;
  (5) ventilation and smoke management systems; and
  (6) all secure door-locking mechanisms which operate exclusively on electric current.
(b) The alternate power source system (i.e., the alternate power source and the required life safety system) shall be tested at least once every 15 calendar days to ensure the system is in working condition.
(c) The alternate power source system shall be inspected at least once each year, no later than the last day of the calendar month of the previous year's inspection. This inspection must be completed by a person with qualifications established through work experience, relevant training, specialized licensure, or certification.
(d) Each test and inspection of the alternate power source system shall be documented and include the test date and test results.

(f) The facility shall maintain a log to document all tests, inspections, and maintenance performed on the alternate power source.
(g) If a facility uses multiple alternate power sources (i.e., gas- or diesel-powered emergency generator and a battery backup), all of the alternate power sources shall be considered part of the alternate power source system.
