Built for dependable fire monitoring in demanding environments, the Thermotech 302-AW-135 all-weather heat detector delivers fast, predictable detection where smoke detectors may not be suitable. This Thermotech heat detector uses rate-anticipation technology to operate within a tight two- to three-degree range of its 135°F set point, helping reduce nuisance alarms and ensuring timely response. The 302-AW series is self-restoring so it returns to service automatically—minimizing maintenance and downtime—and its weatherproof construction allows exterior or harsh indoor placement without a special backbox. Designed for ceiling mount installations with 40' interior/vertical mounting guidance and wired 120V AC connectivity, it integrates easily with fire panels and security monitoring systems. FM and UL listings provide added assurance for commercial and industrial security and surveillance applications.
