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.
302 Series
Rate-Anticipation Heat Detectors
• Eliminates false alarms. The 302 Series do
not respond to momentary temperature
fluctuations below the selected temperature.
Description
• Universal application. The 302 Series can be
used in all areas for any type of occupancy.
The Thermotech 302 Series rate-
anticipation 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.
• Self-restoring.
• Hermetically sealed, shock resistant,
corrosion resistant, and tamper-proff.
The 302 Series are normally-open
devices designed especially for fire
detection and alarm systems.
Principles of
Operation
The 302 Series rate-anticipation
heat detectors respond and
Listings
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.
Listings and approvals below apply to the

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.
