302-ET-194 Notifier, 194 °F (90° C) vertical mount, indoor or outdoor use. Can be mounted to 1/2” conduit threads for attachment to threaded hub cover.

The 302-ET-194 Notifier Series rate-anticipation heat detectors operate within a controlled range of two to three degrees of their set points, regardless of the speed or rate of temperature rise. The 302 Series are normally-open devices designed especially for fire detection and alarm systems.

• 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 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 fluctuations below the selected protection level, thus eliminating false alarms. When the temperature drops back down below the protection level, the detector automatically resets itself.
