NFPA 72

NFPA 72 requires regular visual inspections of fire alarm components to verify they are in their normal condition and free from physical damage or obstruction:

• Monthly — Fire alarm control panels (verify normal condition indicators, no trouble signals), interface equipment, batteries (check for corrosion, swelling, leakage)
• Quarterly — Notification appliances (horns, strobes, speakers) for physical condition, duct detectors for accessibility, guard tour equipment
• Semi-Annual — Initiating devices (smoke detectors, heat detectors, manual pull stations) for physical condition and proper mounting, in-building fire emergency voice/alarm communications equipment

Visual inspections verify that devices are present, properly mounted, undamaged, unobstructed, and showing normal status indicators. Any device found with physical damage, paint or dust contamination, or improper mounting must be noted as a deficiency and corrected.

Smoke detector sensitivity testing is a critical requirement that goes beyond standard functional testing. NFPA 72 requires:

• Initial test — Within one year after installation to establish a baseline sensitivity reading
• Ongoing testing — Every two years thereafter using a calibrated sensitivity testing instrument
• Acceptable range — Detectors must respond within their listed sensitivity range. Detectors found outside this range must be cleaned, recalibrated, or replaced
• 5-year milestone — After five years, sensitivity testing determines whether detectors need replacement due to aging-related drift. Many jurisdictions recommend replacement at 10 years regardless of test results

Sensitivity testing requires specialized equipment (such as a calibrated smoke source or a manufacturer-specific test device) and trained personnel. It cannot be performed using standard aerosol smoke cans, which only verify that the detector responds to smoke, not that it responds within its listed sensitivity range.

Fire alarm ITM requirements vary across the tri-state area. Each jurisdiction references NFPA 72 but may impose additional requirements:

• New York City — Fire alarm inspections must be performed by FDNY-licensed contractors. Inspection reports are filed through the FDNY Business Portal. NYC has additional requirements for high-rise buildings, including more frequent testing of emergency communications systems. The FDNY may require witnessed testing for certain system types.
• New Jersey — Fire alarm technicians must hold state licenses. Inspection reports are filed with local fire officials and the DCA. NJ adopts NFPA 72 through the Uniform Fire Code with limited amendments. Central station monitoring is required for most commercial buildings.
• Connecticut — Fire alarm inspections are overseen by the State Fire Marshal and local fire marshals. CT follows NFPA 72 under the state fire safety code. Inspection companies must be registered with the state. Some municipalities have additional filing requirements.

Inspection companies operating across multiple jurisdictions must maintain appropriate licenses for each state and understand the specific filing and documentation requirements for each AHJ.
