HC-207A Ionization Smoke & Heat Detector


1.Has monitoring function.  The LED flashes once
   every 4 ~ 6 seconds.

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

3.It provides the wiring (-R) function of entrance LED.

4.The use of common base is advantageous to the
   exchange of detector.

5.Fixed Temperature On 60° C
Functioning way

The detector has the functions of both smoke detector and temperature detector.  As there is smoke getting in the detector, the detector functions and sends out alarm.  Meanwhile, it can also be a heat barrier.  As the temperature rises and exceed the preset temperature standard, the detector will also function and send out alarm.  The detector has two probing ways.  It can probe the smoke as well as the change of temperature.  It strengthens the probing functions of the detector.
