Smoke Detector Inspections & Testing

Smoke detectors are your earliest warning of a developing fire — but only if they're properly calibrated and maintained. Titan Life Safety provides NFPA 72-compliant annual inspections and sensitivity testing to ensure your detectors respond correctly when smoke is present.

NFPA 72 Compliant

All inspections meet current NFPA 72 National Fire Alarm Code requirements

Sensitivity Test Reports

Documented sensitivity results for annual and 3-year testing requirements

Annual & 3-Year Service

Functional testing annually; sensitivity testing every 3 years per NFPA 72

Replacement Program

End-of-life detectors identified and replaced to keep your system current

NFPA 72 requires annual functional testing and sensitivity testing every 3 years for all smoke detectors.

Detectors older than 10 years should be replaced — aging sensors become unreliable and may not detect smoke.

WHAT WE SERVICE

All Smoke Detector Types

Ionization Smoke Detectors

Respond quickly to fast-flaming fires with small combustion particles. Common in residential and light commercial applications.

Photoelectric Smoke Detectors

More responsive to slow, smoldering fires that produce larger particles. Recommended for bedrooms and areas near kitchens.

Combination Detectors

Incorporate both ionization and photoelectric sensing for broader coverage. Increasingly required by code in new construction.

Duct Smoke Detectors

Installed in HVAC ductwork to detect smoke being circulated through the air handling system. Trigger HVAC shutdown to prevent smoke spread.

Beam Smoke Detectors

Use a projected light beam across large open spaces such as atriums, warehouses, and churches. Cover areas too large for spot-type detectors.

Aspirating Smoke Detection (ASD)

High-sensitivity systems that actively sample air from protected spaces. Used in data centers, clean rooms, and other high-value environments.

WHAT WE FIND

Common Smoke Detector Issues

Out-of-Sensitivity Detectors

Detectors that are too sensitive cause nuisance alarms; those that are not sensitive enough may fail to detect a fire. Sensitivity testing identifies both conditions.

Contaminated Detectors

Dust, insects, paint overspray, and cooking residue can contaminate detector chambers, causing false alarms or reduced sensitivity.

End-of-Life Detectors

Smoke detectors older than 10 years should be replaced per NFPA 72. Aging detectors become unreliable and may not respond to actual smoke.

Improper Placement

Detectors installed too close to HVAC vents, in dead air corners, or at incorrect heights may not detect smoke effectively. We identify placement violations.

Missing Detectors After Renovation

Building modifications often create areas that are no longer covered by the original detector layout. We identify coverage gaps.

Failed Duct Detector HVAC Shutdown

Duct detectors must trigger HVAC shutdown when activated. We verify the shutdown function works — not just that the detector activates.
