One class carries a single verb. 28 TAC § 34.611 issues the FIRE ALARM MONITORING TECHNICIAN license for the monitoring of fire alarm or fire detection devices and systems, and nothing else — no installing, no servicing, no certifying, no planning. It is the narrowest class by function where the single station license is the narrowest by device, and a registered firm holding only this class can operate a central station and can do nothing at a protected property.

Whether a firm is in that business at all is decided by the statute rather than by the firm. Insurance Code § 6002.002 defines monitoring as the receipt of fire alarm and supervisory signals, or the communication of those signals to a fire service communications center in Texas or serving property in Texas. Two of those phrases carry the whole definition and neither is defined anywhere in these sources. SUPERVISORY SIGNAL and FIRE SERVICE COMMUNICATIONS CENTER are terms the statute uses and leaves alone, and their ordinary trade readings — a signal about the system’s own readiness rather than a fire, and the entity that receives alarm signals so a fire response can follow — are readings rather than sourced definitions. Because they decide whether a firm is in the monitoring business at all, the State Fire Marshal’s Office is who to ask rather than the question to assume an answer to. Receipt alone is enough — a firm does not have to dispatch anyone to be monitoring. And 28 TAC § 34.613 adds a commercial test that catches the arrangement people assume sits outside the rules: a firm BILLING A CUSTOMER for monitoring is engaged in the business of monitoring and must comply with the insurance requirements of the subchapter for a monitoring firm. Subcontract the signals to somebody else’s central station, keep the invoice, and the rule still places you in the business.

The staffing requirement is separate from the license and is easy to miss, because neither of the two rules that carry it is the licensing one. 28 TAC § 34.616 requires a registered firm to employ at least one technician licensee AT EACH CENTRAL STATION LOCATION, and states that each dispatcher at the central station is not required to be a fire alarm technician licensee. Separately, 28 TAC § 34.613 requires an applicant firm engaging in monitoring to provide the specific business locations where monitoring will take place together with the name and license number of the fire alarm licensees at each — and provides that a fire alarm licensee may not serve in that capacity for a registered firm other than the applying firm. So the room needs a licensee, the people answering signals in it do not each need one, and the licensee who anchors it is anchored to one firm.
