28 TAC § 34.607 adopts seventeen entries, each named with the edition or the date that governs it. Three of them do the work in this trade. The central one is NFPA 72-2019, which the rule titles the National Fire Alarm Code. Beside it sit NFPA 70-2020, the National Electrical Code, and NFPA 101-2021, the Life Safety Code. A firm running a central station meets a fourth, UL 827 of December 3, 2021, the Standard for Central Station Alarm Services. The remaining entries are sprinkler, extinguishing, water-based and ventilation standards that other trades work to. The rule adopts them alongside the fire alarm ones, and the rule itself is where to read the full list.

The edition year is the operative fact, and it is why this list is worth returning to rather than remembering. A newer edition of any of these exists or will exist; none of them becomes the Texas standard by being published. The rule names a year, and that year governs until the rule itself is amended to name a different one. So a question about what the standard requires is always preceded by a question about WHICH standard — and the answer to the second is here, in a Texas rule, rather than in the standard.

One entry works differently from the rest, and it is the reason § 7.5 exists. The Life Safety Code entry carries an alternative on its face: NFPA 101-2021, OR a local jurisdiction may adopt one set of the model codes listed in the rule’s own subsection instead of NFPA 101. No other entry offers that. And 28 TAC § 34.608 supplies the other half of how these documents reach real equipment: the commissioner approves an organization as an APPROVED TESTING LABORATORY where it lists equipment and appurtenances for use in compliance with the standards adopted in 28 TAC § 34.607, and meets the requirements of an approved testing laboratory. The standard sets what compliance means; the laboratory certifies that a given product meets it; and the rule requires the label. Three separate steps, none of which this book is the source for.
