| - 135°F - Explosion Proof Mounting UL
- Immediate Response - The 302 Series activate whenever ambient air temperature reaches a detector's setting, eliminating the thermal time lag inherent in conventional heat detectors.
- Eliminates False Alarms - The 302 Series do not respond to momentary temperature fluctuations below the selected temperature.
- Universal Application - The 302 Series can be used in all areas for any type of occupancy.
- Self-restoring
- Hermetically sealed, shock resistant, corrosion resistant, and tamper-proof.
The 302 Series rate-anticipation heat detector respond and activate the fire alarm immediately whenever the ambient temperature reaches the preset temperature setting. Under rapid heat rise conditions, the rate-anticipation feature enables the detector to respond one to three degrees ahead of the setting. At the same time, however, it does not respond to momentary temperature fluctuations below the selected protection level, thus eliminating false alarms. When temperature drops back down below the protection level, the detector automatically resets itself. Application Information 302 Series detectors have a smooth-ceiling UL rating of 50' x 50' (15.24 x 15.24 meters) and are the only type of heat detectors having such a rating on both fixed temperature and rate anticipation.
