Hochiki Fixed temp/rate of rise heat sensor

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.
