FIBARO Smoke Sensor responds to the physical presence of a smoke. The device checks every 10 seconds for a smoke. Once the level of smoke exceeds value set in advanced parameter 1, Smoke Sensor triggers an alarm.
Optical smoke detector used in FIBARO Smoke Sensor has 3 levels of sensitivity, compliant with EN 14604:2005. By default, the detector is set to the middle sensitivity level. Sensitivity level depends on the parameter 1 settings (modified only through the main Z-Wave controller).
Fire alarm is signaled by:
- sending an appropriate alarm command to the Z-Wave controller
- sending an appropriate alarm command to associated devices
- intermittent sound
- visual indicator blinking red
Once the fire alarm has ceased, the sensor checks whether the smoke has actually disappeared before getting back to normal operation, i.e. performing a self test each 10 seconds and checking for presence of smoke.
FIBARO Smoke Sensor is a multiple use device, however, for greater safety, it is recommended to replace the device with a new one after a fire occurrence.
If fire alarm is triggered, but the level of smoke did not exceed concentration equal to three times of the sensitivity set in parameter 1 (the individual levels of sensitivity are printed on the device casing), user can mute sound alarm by holding the B-button (temporarily reducing the sensor’s sensitivity).
Visual indicator will still indicate an alarm state by blinking red. If smoke level concentration is greater than three times of the sensitivity set in parameter 1, mute will automatically turn off and the device will alarm fire again (using visual and audible indicator).
