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

302 Series M Rate-Anticipation Heat

Detectors. In some cases, certain modules

may not be listed by certain approval

agencies, or listing may be in process.

Consult factory for latest listing status.

• UL Listed: file S539 & E35018A.

• CSFM approved: file 7270-0021:001.

• FM approved: file

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.
