302-ET-194 数据手册
302 Series Features • Immediate response. The 302 Series activates 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-proff. Rate-Anticipation Heat Detectors Description The Thermotech 302 Series rateanticipation heat detectors operate within a conrolled range of two to three degrees of their set points, regardless of the speed or rate of temperature rise. These detectors are available in either 135° F or 194° F ratings. The 302 Series are normally-open devices designed especially for fire detection and alarm systems. The 302 Series rate-anticipation heat detectors 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 flucuations below the selected protection level, thus eliminating false alarms. When temperature drops back down below the protection level, the detector automatically resets itself. 6935pho1.jpg Principles of Operation Listings Listings and approvals below apply to the 302 Series M Rate-Anticipation Heat Detectors.
