## Overview

The ELRO FC5003 Carbon Monoxide Detector combines a high-quality 10-year electrochemical sensor with a user-friendly digital display and 3-year included batteries, ensuring reliable, long-term protection against odorless, invisible carbon monoxide gas. Certified to European Standard EN50291, it features loud alarms, low battery alerts, and convenient mute functions, making it an essential, professional-grade safety device for modern homes.

## Description

The Elro FC5003 carbon monoxide detector ensures that you are alerted in time of the appearance of poisonous carbon monoxide gas. This gas is odourless and invisible, so undetectable without a detector. Carbon monoxide is caused by incomplete combustion and can come from a fireplace, water heater or central heating boiler. This detector from Elro is equipped with a high-quality electrochemical sensor that constantly measures the concentration of carbon monoxide in the air. The display displays the CO concentration. If the concentration levels are too high, the detector emits a loud 85dB alarm. Elro FC5003 conforms to European standard EN 50291-1:2010. Key Features Reliable electrochemical sensor With display Test button to check functionality Includes 2 x AA batteries with a lifespan of 2 years Low battery warning Low battery warning mute function Alarm signal mute function Box contents: Elro FC5003 Carbon Monoxide Detector 2 x AA batteries with 2 year life Mounting material Instruction manual Installation The FC5003 Carbon Monoxide Detector comes with the necessary mounting material (screws and dowels). This allows you to attach the detector to the wall quickly and easily. Hang on the wall at a height of about 1.5 m from the floor. Also make sure to stay at least 1.85m from the reach of a combustion device. Note that the test volume is less than the actual alarm sound, as the alarm can be harmful to your hearing when you are nearby.
