The FIBARO CO sensor will make your home safer and prevents danger caused from the ‘silent killer’ carbon monoxide (CO). The sensor detects reliable carbon monoxide in the air and alarms in case of exceeded limits. Its high sensitivity allows to detect the presence of the carbon monoxide (CO) gas at the early stage in order to prevent carbon monoxide poisoning.The device alarms via an integrated siren and blinking LED. Additionally, automatic scenes can be triggered within the Z-Wave gateway and notifications can be sent.Additionally the device is equipped with a temperature sensor.The FIBARO CO Sensor is a life-saving device, therefore tests to conform compliance with the applicable requirements of the standard EN 50291-1:2010 are conducted by the BSI Group accredited testing laboratory. Each sensor is subject to continuous control, which covers routine product testing and the evaluation of manufacturing quality control processes.
