The Firesco FCO-850 WF carbon monoxide detector is a modern device that provides reliable protection against dangerous carbon monoxide (CO) emissions in your home. Equipped with a highly accurate electrochemical sensor, the detector boasts a long lifespan – up to 10 years. Thanks to this high-quality technology, the Firesco FCO-850 WF can detect even minimal concentrations of carbon monoxide, allowing early action and ensuring safety for all household members.
When CO concentration exceeds the permissible level, the detector immediately activates a loud 85dB sound alarm that will effectively get your attention. Additionally, a red LED indicator signals the detected danger, ensuring quick and easy recognition of the alarm state. This way, the Firesco FCO-850 WF operates effectively even in critical situations when every second counts.
The Firesco FCO-850 WF is equipped with a WiFi module that enables connection to the Tuya network and sends real-time notifications to the user’s app. This allows you to continuously monitor the device’s status and be sure that you are always informed about detected threats, no matter where you are. The WiFi module also increases compatibility with other smart home devices, enabling easy management of all safety systems from one place.
The Firesco FCO-850 WF detector is powered by two AA alkaline batteries (2 x 1.5V), ensuring uninterrupted operation even during mains power outages. This power system guarantees full mobility – no socket connection is required, allowing installation anywhere. Thanks to battery power, the detector remains fully operational 24/7, even during power failures.
The Firesco FCO-850 WF offers convenient operation with a Test/Silence button, allowing quick device checks and muting of false alarms. Additionally, the built-in monitoring system for battery level and sensor status provides full control over the device, informing you of the need for intervention via a yellow LED and sound signal. The detector can be easily mounted on a wall or placed on a flat surface, such as a nightstand, so you can adapt it to your needs and space. Moreover, the device can operate as a standalone unit or work with the app in smart home mode, ensuring both convenience and safety.
