Security and Fire Alarm Systems Installers in the Chattanooga Metro

BLS metro-level wage data places Security and Fire Alarm Systems Installers pay in Chattanooga, TN-GA at a median of $48,330 per year ($23.24/hr), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared with the national median of $60,070, the metro estimate is 20% below. OEWS reports the difference but does not identify its cause. Approximately 160 security and fire alarm systems installers are employed across the Chattanooga MSA in SOC 49-2098.

The Chattanooga pay distribution spans from $37,890 at the 10th percentile to $77,690 at the 90th, a 2.1× observed spread. Differences in specialization, employer, sector, location, credentials, schedule, and experience may all contribute, but OEWS does not isolate their effects. The 25th percentile sits at $41,440 and the 75th at $59,360, so half of Chattanooga-based security and fire alarm systems installers earn within that middle band.

Metro figures use establishment work location, not worker residence. BLS draws metro boundaries from the OMB MSA definitions, so Chattanooga, TN-GA covers the central city plus outlying counties tied to the metro economically. OEWS includes straight-time pay, tips, commissions, incentive pay, and production bonuses. It excludes employer health and retirement benefits, overtime premiums, stock compensation, signing bonuses, and other nonproduction bonuses. The same occupation's national profile, statewide TN estimate, and peer-metro rows provide distinct geographic comparisons. A published median is a benchmark, not a prediction or ceiling for one worker.
