- The optical sensor uses the scattered-light method. An LED transmits light to the measuring chamber, where it is absorbed by the labyrinth structure. In the event of a fire, smoke enters the measuring chamber and the smoke particles scatter the light from the LED.
- Depending on the specified detector class, the temperature sensor triggers the alarm status when the maximum temperature of 54 °C or 69 °C is exceeded(thermal maximum), or if the temperature rises by a defined amount within a specified time (thermal differential)
- A red flashing LED visible 360° indicates the alarm
- Operating voltage 15 V DC to 33 V DC
- Automatic addressing
- The response threshold (drift compensation) is actively adjusted
- In the event of wire interruption or short-circuit, integrated isolators maintain the functional security of the LSN loop
- Maximum installation height: Max. 16 m
- Monitoring area: Max. 120 m2
