MODEL 302-AW-135 & 302-AW-194

Hermetically sealed for moisture proof or dust proof installations. For indoor and outdoor use. Protect from direct sunlight and adverse weather conditions.

Principal of Operation:

These ALL WEATHER heat detectors operate on the principles of a rate compensation detector. The heat detector consists of a high expansion aluminum tube which encases two insulation struts with opposing open constant points. The high expansion sensing shell and the expansion struts have a different coefficient of expansion. A slow rate of temperature rise allows the heat to penetrate the inner expansion struts. Therefore, the tubular shell and the struts expand slowly until the total device has been heated to its rated temperature level of 135 degree F. or 194 Degree F. At this point, the silver contact points close which initiates the alarm. When subjected to rapid rate temperature rise there is not as much time for heat to penetrate the inner strut. The rapid lengthening of the shell allows the struts to come together at a lower level which compensates for thermal lag inherent in conventional fixed temperature detectors. When the surrounding air temperatures go below the rated temperature level, the shell contracts which forces contacts to open, thus automatically resetting the detector.

General:

These ALL WEATHER heat detectors are normally open devices designed especially for fire detection and alarm systems. These rate compensation type detectors are available in either 135 degree F or 194 degree F models. These ALL WEATHER heat detectors are self restoring, hermetically sealed, shock and corrosion resistant, and are tamper proof. Refer to NFPA Standard 72, Standard for automatic fire detectors for application requirements, testing and maintenance.
