Inspection, Testing, Maintenance, and Documentation
The ITM cycle
NFPA 72's inspection, testing, and maintenance chapter assigns intervals by component and action. Recurring obligations typically include monthly visual inspection of the panel and annunciator for normal conditions and a spot check of the records; quarterly or annual testing of supervisory devices such as valve tamper switches and waterflow switches (check the table for the specific device); and annual testing of initiating devices, notification appliances, batteries (load test), and the sequence of operations, including interfaces. Smoke detector sensitivity is verified within one year of installation and periodically afterward (commonly every two years) unless the manufacturer's instructions or an approved performance-based plan say otherwise. The interval that applies is the one in the edition adopted in NYC - not what a contractor "usually" does. Maintenance means replacing failed components, cleaning per the manufacturer, battery replacement on condition or schedule, and correcting anything that impairs the system.
Documentation
The Record of Completion (installation) and the Record of Inspection and Testing (each ITM event) are the backbone. Keep as-builts, the sequence of operations, battery calculations, device lists, and manufacturer manuals on site; record dates, tester identity and qualification, devices tested, and deficiencies with corrective actions. NYC requires annual inspection and testing reports to be retained and produced to the FDNY on request. Impairments follow the notification rules: notify the FDNY and the monitoring company, implement a fire watch where required, and log restoration.
Traps
- Testing representative samples on a periodic basis (sampling is not permitted for periodic device testing).
- Recording a test before the deficiency is corrected, or leaving deficiencies open with no follow-up date.
- Changing a device without updating the record and the battery calculation.
- Failing to document notification of the AHJ during an impairment.
Rule of thumb
If it is not written down, it was not tested - the record must stand alone without the tester present.
