Description :

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. Functioning way: outside the fixed-temperature heat detector are exposed a temperature-sensing heat barrier. When the fire makes the room temperature rise gradually until the temperature has risen and reached the preset point of function temperature, it immediately enters the alarm status. Meanwhile, LED will be turned on automatically and give alarm to the fire signal receiving machine.
