HC-306A Rate of Rise Heat Detector


1.There are two LEDs which can turn 360o and 
   watch the situation of the detector at any angle.

2.The use of common base is advantageous to 
   the exchange
of detector.
Functioning way

As the fire is formed rapidly, the rapid heat convection and hot wind make the room temperature rise drastically.  The Rate of rise heat detector can detect the speedy rise of temperature within a short period of time.  It then functions and enters an alarming situation.  Meanwhile, the LED will be turned on automatically and give alarm to the fire signal receiving machine.
