Carbon monoxide alarm Firesco FCO-850 WF based on an electrochemical sensor with high accuracy and durability min. 10 years. There is a Test / Hush button that allows you to check the operation of the device and silence false alarms.

It continuously measures the concentration of carbon monoxide (CO) in the surrounding air. Exceeding the permissible CO level is signaled optically (red LED) and acoustically (loud sound alarm with a strength of 85dB).

The WiFi communication module enables connection to the Tuya network. The sensor can also be used as a stand-alone unit, without the need to connect to the application. Once connected to the home network, the sensor will send alarm messages as well as any other prompts to the user's application in real time.

It is manufactured in accordance with the EN50291-1:2018 standard. It has a certificate confirming that it meets the above requirements. standards issued by an independent European research unit.

The sensor is intended for free-standing installation. The specially designed housing allows it to be placed on a flat surface, e.g. on a nightstand near the bed.

It has a system that monitors the battery level, sensor status and internal circuits. If any irregularity is detected, the sensor activates a yellow LED and an acoustic signal appropriate to the type of fault.

FCO-850 WF is powered by 2 x 1.5V alkaline batteries, type AA, thanks to which which also provides protection in the event of a power outage in the network. After 10 years after activating the power supply, the sensor will remind you to replace the device.

Kitchens, bedrooms, rooms with devices that may be a source of carbon monoxide, e.g. gas boilers and stoves, gas stoves, oil and coal-fired devices, portable space heaters, combustion devices, fireplaces, tiled stoves, coal stoves, etc.
