Compliance

• UL Listed
• FM Approved
• NFPA 72
• MEA Accepted

Key features

• 194°F (90°C) fixed-temperature set point for areas where ambient temperatures can approach 135°F
• All-weather construction tolerates outdoor exposure including rain, condensation, and wide temperature cycling
• Rate-compensated mechanical design prevents thermal lag and reduces false activations from slow ambient temperature drift
• FM Approved for property protection applications in FM Global-governed industrial facilities
• Compact total length of 4⅛ inches for installation in confined or low-clearance spaces

Thermotech 302-AW-194 detectors are deployed in outdoor and semi-outdoor locations where the 135°F (57°C) model would be susceptible to nuisance actuation from normal summertime ambient temperatures. Typical applications include exterior covered walkways, open parking decks, rooftop equipment enclosures, and loading dock canopies. The mechanical fixed-temperature element operates without electrical power until actuation, making the 302-AW-194 suitable for use on conventional four-wire initiating device circuits and compatible with most fire alarm control panels that accept contact-closure type heat detectors. Confirm mounting orientation and spacing requirements with NFPA 72 Table for fixed-temperature detectors in the installation environment.

Verify panel/device family compatibility before ordering.
