The Fibaro Smoke Sensor is a universal, optical Z-Wave Plus smoke sensor. The device is battery operated (battery life of up to 3 years).
Smoke detection is signaled through siren and LED diode blinking.
The optical sensor detects smoke at an early stage of fire, often before flames appear and temperature starts to rise significantly. Moreover the device has a built-in temperature sensor, which can also trigger the alarm once the specified temperature threshold is exceeded.
The Fibaro Smoke Sensor is designed to be placed on a wall or ceiling. LED indicator signals fire, operating mode and used to see if device is within the Z-Wave network. The smoke sensor is designed to operate in confined spaces, under normal conditions (lacking smoke, dust, condensed water vapor).
