Manual fire alarm systems must be tested by a(n) __________.

Manual fire alarm systems must be tested by a holder of the S-97 or S-98 Certificate of Fitness. These certificates specifically qualify an individual to perform testing, maintenance, and service of fire alarm systems, which ensures that they are operational and compliant with safety regulations. Technicians with this certification possess the necessary knowledge and expertise in the components and operation of fire alarm systems, making them adept at identifying issues and conducting thorough inspections.

The S-95 Certificate of Fitness, while related to fire safety, is typically focused on other responsibilities and may not encompass the specific skills required for testing manual fire alarm systems. Similarly, the F-01 and F-02 Certificates of Fitness cater to different areas within fire safety and life safety management, without covering the specialized aspects of fire alarm system testing that the S-97 and S-98 certificates focus on. Therefore, only the S-97/S-98 Certificate of Fitness holder has the appropriate qualifications for this task.
