What type of maintenance cannot be performed by Certificate of Fitness Holders?

The maintenance that cannot be performed by Certificate of Fitness Holders pertains specifically to the testing and cleaning of smoke detectors. This is because such tasks often require specialized knowledge and skills that go beyond general operational oversight.

Testing and cleaning smoke detectors are critical processes that ensure the devices function correctly and reliably in the event of a fire. Professionals conducting these tasks must be familiar with the specific manufacturer guidelines and industry standards to avoid damaging the detectors or compromising their performance. Furthermore, many jurisdictions require that these tasks be performed by certified technicians or professionals due to the importance of this equipment in life safety.

In contrast, visual inspections of fire alarm systems, basic troubleshooting, and running system diagnostics are tasks that Certificate of Fitness Holders are generally authorized to perform. These duties involve checking for obvious signs of malfunction or issues that can be identified without specialized skills, ensuring that the systems are operational and compliant with safety regulations. By focusing on these tasks, Certificate of Fitness Holders can help maintain the fire alarm system’s readiness, while more technical aspects, like smoke detector maintenance, are reserved for trained professionals.
