Firesco FCO-850 SA Carbon Monoxide Detector

Firesco Carbon Monoxide Detector basic version FCO-850 SA



Precise protection for your home

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 an electrochemical sensor of exceptional accuracy, the detector features longevity – with a lifespan of up to 10 years. Thanks to such high-quality technology, the Firesco FCO-850 WF can detect even minimal concentrations of carbon monoxide, allowing early action and ensuring the safety of all household members.

Ease of use and alarm functions

The Firesco FCO-850 SA detector offers easy operation thanks to the Test / Silence button, which allows quick verification of the device's operation and muting of false alarms. In the event of detecting a dangerous CO concentration, the detector immediately signals danger via optical (red LED) and acoustic (loud 85dB alarm) alerts. This ensures a rapid response and safety for household members.

Power supply and constant readiness

The Firesco FCO-850 SA detector operates on two AA alkaline batteries (2 x 1.5V), ensuring continuous protection even in the event of a mains power outage. Thanks to battery power, the device is completely mobile and can be installed anywhere in a room without the need for a power outlet. Additionally, the detector will remind you to replace it after 10 years from activation, guaranteeing long-term protection.

Monitoring and diagnostics

The Firesco FCO-850 SA is equipped with a self-diagnostic system that continuously monitors battery level, sensor status, and internal circuits. If any irregularity is detected, the detector activates a yellow LED and an appropriate sound signal, informing the user of the need for intervention. This gives you full control over the device's condition and enables quick reaction to emerging problems.
