What must be maintained by a firm according to the rules governing a Certificate of Registration?

The requirement for maintaining a specific location that must be listed on the certificate relates directly to the accountability and traceability of the firm within the framework of fire alarm regulations. This ensures that there is a designated physical address where the firm operates, which is crucial for regulatory oversight and for customers to know where to seek services, support, or lodge complaints.

Having a specific location enhances transparency and promotes trust among clients and regulatory authorities, as it provides a point of contact for verification of the firm’s compliance with fire alarm standards and practices. This is especially important in an industry that deals with safety-critical systems, as any lack of clarity about the firm's operations could lead to significant risks in service delivery.

While other options like maintaining lists of technicians, conducting financial audits, or having security plans are important aspects of running a business in the fire alarm industry, they are not typically mandated as a condition for the Certificate of Registration like the essential requirement of having a documented operational address.
