What Actually Changed in NFPA 72 Chapter 14 (2019, 2022, and 2025)
Most fire alarm coverage of a new NFPA 72 edition starts with design: detector spacing, new device types, survivability levels. That's useful if you're laying out a system. If you're the technician standing at the panel, or the office manager building the report template, the changes that matter live in Chapter 14, Inspection, Testing, and Maintenance.
This guide covers just those changes across the last three editions, plus the few changes outside Chapter 14 that land on the person doing the ITM. Every item is sourced to NFPA's own committee reports or to trade coverage of the published edition. Items that only appear in a draft-stage NFPA document are labeled as drafts.
One caution before you start. The edition you inspect to is whichever one your jurisdiction has adopted, not the newest one NFPA has published. Check with your AHJ before you change a single line on a form.
2019 → 2022: what changed for the technician
Waterflow and tamper switches moved from quarterly to semiannual
In the 2019 edition, Table 14.3.1 called for a quarterly visual inspection of waterflow and supervisory (tamper) switches. The 2022 edition changed both to semiannual. The committee's reasoning, from First Revision 5219, was consistency: it "aligns the frequency of inspection for condition and location of tamper switches and waterflow switches with the frequency for all other equipment, except for flame detectors and video smoke detectors." Electrical Contractor confirmed the change in its overview of the published 2022 edition.
Two practical notes:
This is a fire alarm inspection frequency. If the same switches are also covered by an NFPA 25 sprinkler inspection program, that standard sets its own schedule. Don't assume one change cancels a visit required by the other.
If your recurring jobs were built on a quarterly schedule for these devices, the schedule is now out of date in any jurisdiction on the 2022 edition or later.
A new category on the report: the "observation"
Before 2022, a finding was either an impairment or a deficiency. The 2022 edition added a third category. It defines an observation as "a suggested correction, improvement, or enhancement to the fire alarm or signaling system that is not considered to be an impairment or deficiency" (FR-5236). The committee was explicit that "owners are not required to address observations that are not impairments or deficiencies" (FR-5235).
This matters for how reports get written. An aging panel that still works, a device that would be better placed elsewhere, a recommended upgrade: those are observations. Writing them up as deficiencies overstates the problem to the owner, and an AHJ may read them the same way. The cleanest fix is a separate section or field on the report so a technician can't blur the categories by accident. Security Sales & Integration describes the new section the same way: the inspector can comment on improvements, and the owner doesn't have to act unless they become impairments or deficiencies.
Remote software changes still need someone on site
Remote (off-site) programming of control units was becoming possible, and the 2022 edition addressed what that means for reacceptance testing. The committee added language "to state that remote programming must be verified by a qualified person in accordance with 14.4.2" (FR-5288). Electrical Contractor summarized the published rule as requiring on-site verification by a qualified individual.
In practice, a remote programming change creates a site visit and a reacceptance test record. It doesn't remove either one.
An optional red and yellow tagging program (Annex I)
The 2022 edition added Annex I, a color-coded tagging program. Per Security Sales & Integration, a yellow tag applies "if one or more deficiencies are noted during the inspection and/or test," and a red tag applies "if any part of the system is found to be inoperable or impaired."
Annex I is informational, not mandatory. It only becomes a requirement where a jurisdiction adopts it. Some 2025 coverage lists the tagging annex as new in 2025. It isn't. It has been in the standard since 2022.
2022 → 2025: what changed for the technician
RAMO areas add annual testing and an annual review
The 2025 edition introduced restricted audible mode operation (RAMO), a notification mode for areas where loud sounds could be detrimental to sensitive occupants. NFPA's Second Draft public comment responses record the new section 18.4.1.8 and the matching Chapter 7 documentation requirements. For ITM, Consulting-Specifying Engineer reports that RAMO areas need annual testing that measures and records ambient and maximum sound pressure levels, plus an annual review of how those areas are occupied. A separate CSE piece on 2025 documentation changes describes the same annual testing and occupancy review.
For the report, that means two new data points on any system with a RAMO zone: recorded sound pressure levels, and a record that the occupancy review was done.
New detector types you'll start to see
The 2025 edition adds two initiating device types (Electrical Contractor):
Device | Section | What it does |
|---|---|---|
Acoustic leak detector | 17.11 | Detects the sound of a pressurized gas release (also called an ultrasonic gas detector) |
Thermal image fire detector | 17.12 | Senses overheated combustible material by imaging in long-wave infrared |
On the ITM side, the 2025 First Draft tied thermal image detectors to the manufacturer. They "shall be inspected, tested, and maintained in accordance with the manufacturer's published instructions" (FR-5336), the same approach the standard already took for video image smoke and flame detectors. If your device list is fixed, these need a line and a link to the manufacturer's procedure.
Proposed in the 2025 cycle: check your copy
Two First Draft revisions affect records and batteries. Neither could be confirmed against the final Second Draft for this article, so check the published 2025 text before you build them into a form.
Who keeps the ITM records. The 2022 text made the building owner responsible for permanent records. In the committee's words, "ITM records, however, are not assigned to any entity for retention." FR-5355 proposed: "The system owner shall be responsible for retaining maintenance, inspection, and testing records until the next test and for 1 year thereafter" (2025 First Draft).
Primary batteries. FR-5291 proposed that installers "ensure a minimum of 60 percent shelf life is remaining based on the use-by date printed on the battery" and "record the installed date on the battery," with replacement "not to exceed 12 months from the installed date." The committee noted that US primary batteries carry a use-by date rather than a manufacture date.
What to update, in order
Confirm the adopted edition for each jurisdiction you work in. That decides which of these changes apply to which customer.
Re-time recurring jobs. Move waterflow and tamper visual inspections to semiannual where 2022 or later applies.
Split findings into three categories on the report: impairment, deficiency, observation.
Add fields for remote programming verification to the reacceptance test record.
Add RAMO fields (sound pressure levels, occupancy review) wherever 2025 applies and the system has a RAMO zone.
Add device lines for thermal image and acoustic leak detectors as they show up in the field.
Every item on that list is a change to a form, a schedule or a report. That work multiplies when your customers sit in jurisdictions on different editions. Joyfill lets fire protection contractors build NFPA-based inspection forms that technicians fill out on mobile, so a change in the standard becomes a template update instead of a reprint.
