Sensors in Carbon Monoxide Detectors. Electrochemical sensors use a gel to detect CO. Electrochemical sensors are mainly used to detect Oxygen and toxic gas. They measure a chemical reaction within the sensor that creates an electrical output proportional to the CO level. Essentially, EC sensors are small fuel cells composed of noble metal
Never ignore an alarming CO alarm! It is warning you of a potentially deadly hazard. If the alarm signal sounds do not try to find the source of the CO: Immediately move outside to fresh air. Call your emergency services, fire department, or 911. After calling 911, do a head count to check that all persons are accounted for. DO NOT reenter the
After an alarm is turned on for the first time, it should last approximately 7-10 years in normal operating conditions. This can vary slightly based on the model you own. Check your alarm's manual for the exact warranty period. If your alarm is more than 10 years old, it's time for a replacement. Note: First Alert's Smoke / CO Warranty begins
A. It is recommended to replace your carbon monoxide detector every 5-7 years, as this is the typical lifespan of most detectors. However, it is important to check the manufacturer’s guidelines for your specific model, as some may have different recommended replacement intervals.
1 Answer. There are three major types of carbon monoxide senors. Biomimetic: A gel changes color when it absorbs carbon monoxide. Metal oxide semiconductor: When the chip's circuit detects carbon monoxide, electrical resistance decreases, and this triggers an alarm. Electrochemical: Electrodes immersed in a chemical solution sense changes in
