ATJ-EA – FIXED TEMP/RATE OF RISE HEAT SENSOR

The Hochiki ATJ-EA Fixed Temperature / Rate of Rise sensors provide accurate temperature measurement data to the fire alarm control panel. These sensors are well-suited for environments where dust, cooking fumes or other factors make the use of smoke sensors impractical.

  • • Low profile – only 2.00″ high, including base
    • Simple and reliable device addressing method
    • Uses the noise immune Digital Communication
    • Protocol (DCP), which utilizes interrupts for fast response to fires
    • Rate of rise temperature threshold = 15°F / 8.33C per min (determined by panel)
    • Adjustable threshold temperature = 135°F / 57.2°C – 194°F / 90°C  (determined by panel)
    • UL maximum spacing of 70 feet
