The 2025 edition of NFPA 72: National Fire Alarm and Signaling Code is now published. Many jurisdictions will keep using older editions for a while, yet project teams still need to understand the new text. Knowing the shift early helps you design, budget, and plan upgrades that will pass future reviews.
1) Cybersecurity moves from advice to rule
In 2022 the code created Chapter 11 with one short statement and parked the real guidance in Annex J. The 2025 book lifts that guidance out of the annex and places it directly in Chapter 11.
What it now requires
- Assign a security level to every fire-alarm network based on how it connects to the internet or other systems.
- Keep written cyber-maintenance steps, including patch schedules and password rules.
- Manufacturers must show UL or similar listings that prove their products meet the cyber controls.
Action for managers
Add your fire-alarm network to the site’s existing cyber risk process. Check that each panel, gateway, and cloud dashboard meets the new listing clause. Keep proof on file for the next inspection.
2) Remote access refined
Remote reset, silence, or software upload first entered the code in 2022. The 2025 text tightens those rules: remote links must disconnect after a preset time, a qualified person must stand on-site during any critical change, and the link needs an easy “kill switch.”
Action for managers
- Ask your service firm for the written remote-access procedure.
- Make sure staff know how to end a session if it misbehaves.
- Log every remote event with start and end times.
3) Smoke-detector spacing above 40 ft
Traditional spacing tables now stop at a 40-foot finished ceiling. Higher roofs such as those found in atriums, warehouses, and big-box retail must follow a performance-based design with modeling or full-scale test data. Why does this matter? Above 40 ft, hot smoke cools and stratifies, delaying detector response. The new rule forces designers to prove performance instead of relying on tables meant for lower ceilings.
4) Battery rules get tougher
Beginning with this edition, inspectors look at battery shelf life rather than the date of manufacture. Each rechargeable unit must keep at least 60 % of its rated life at the annual test, or it is replaced. Rechargeable batteries also must be listed by a nationally recognized testing lab (UL, ETL, etc.).
Action for managers
- Keep “best-by” dates on record; mark batteries when installed.
- Stock only UL-listed replacements that match panel specs.
5) Documentation and tagging updates
Consulting-Specifying Engineer notes several scattered text moves that tighten documentation. Digital records, as-built drawings, and remote inspection logs now carry the same weight as paper copies. The code still recommends color-coded condition tags (Annex I), but many AHJs now expect them after seeing the language two cycles in a row.
Action for managers
- Store inspection and test reports in a location backed up off-site.
- Add tagging to your next service contract so the panel shows green, yellow, or red status at a glance.
6) Detector technology trend
Industry commentary on the 2025 cycle predicts a gradual phase-out of single-sensor photoelectric and ionization detectors. Multicriteria devices and video-based detection get stronger support in the annex language, aiming to cut nuisance alarms.
Action for managers
When replacing heads, consider switching to multicriteria models that already carry UL 268 7th-edition listings. You will be ahead of the next cycle.
Quick checklist for compliance
| Task | Who owns it | Target date |
|---|---|---|
| Add fire-alarm network to cyber risk register | IT + Facilities | 30 days |
| Review service contract for remote-access clauses | Facilities + Legal | 45 days |
| Validate UL listing on every spare battery | Procurement | Next order |
| Mark “best-by” date on all batteries in service | Technician | Next inspection |
| Gather digital copies of drawings and test logs | Facilities | 60 days |
| Plan smoke-detector study for ceilings > 40 ft | Designer | Before next remodel |
| Budget for multicriteria detector upgrade | Finance | Next cap-ex cycle |
Closing thoughts
The 2025 edition of NFPA 72 shifts cybersecurity and remote connectivity from nice-to-have guidance to mandatory text. It also asks managers to prove performance in tall spaces and keep closer watch on batteries. Start with the checklist above and involve IT, purchasing, and your fire-protection vendor early. Doing the prep now avoids change orders when your local AHJ finally adopts the new book.
