Nothing in Texas fire alarm law asks what you call yourself. Insurance Code § 6002.151 says an individual or organization may not engage in the business of planning, certifying, leasing, selling, installing, servicing, monitoring, or maintaining fire alarm or fire detection devices or systems unless it holds a registration certificate issued by the department. The trigger is the business engaged in. A company whose sign says low-voltage, or data cabling, or electrical, is inside that sentence the moment its business includes one of those activities, and a company that calls itself a fire alarm firm but does none of them is not made a registered firm by the name.

The rule and the statute describe that business in slightly different words, and it is worth noticing which. 28 TAC § 34.603 says the subchapter applies to persons and organizations engaged in the business of inspecting, planning, certifying, leasing, selling, servicing, testing, installing, monitoring, and maintaining fire alarm or fire detection devices and systems — and not to the general public. Set beside Insurance Code § 6002.151, the rule spells out inspecting and testing where the statute’s list does not, because the statute folds them into its definition of servicing, which § 1.1 set out. The instruments are not in conflict; they are drafted at different grain, and this book cites whichever one actually carries the requirement being discussed.

That last clause of 28 TAC § 34.603 — “and not to the general public” — is where most readers expect the exemptions to begin, and it is not. It draws a line around an audience, not around a set of jobs. The exemptions themselves live in Insurance Code § 6002.155, and their opening words repay careful reading: the LICENSING PROVISIONS of this chapter do not apply to the eleven situations it lists. Not the chapter. Not the standards. 28 TAC § 34.604 then carries those exceptions into the subchapter and says the same thing from the other side — that professionally exempt individuals and organizations are exempt from license requirements only. The rest of this chapter takes the eleven apart, because every one of them is narrower than its summary, and the next section starts with what an exemption does not buy you.
