Manufacturer's DescriptionLarge multi function easy read digital LCD display shows CO level and room temperature. This helps ensure you get the product you want in a condition you're happy with, as well as reducing the miles each product travels, helping to lower carbon emissions. However, carbon monoxide can also pass through walls, so you would also be at risk if a neighbouring property had a leak. To activate your CO alarm, pull the disabling tab out of the alarm and wait up to 1 minute for the green LED to flash to confirm the alarm is active. Examples include boilers, coal fires, wood burners, and gas ovens and cookers, though an exception is often made in legislation for gas appliances solely used for cooking.

When you claim under warranty you must send your faulty part first and we will check if parts are actually faulty, if so we will replace it under the warranty period. Intelligent CO sensing technology enables the alarm's high sensitivity mode to be activated if it predicts CO levels will increase to or above 180ppm for a quicker alert.

Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable). The only way to detect CO in your home is to install a Carbon Monoxide detector with an audible alarm. Where your alarm is installed can trigger nuisance alarms if not correctly placed, for example too close to doors or windows.

The common sources of Carbon Monoxide (CO) are cookers, fires, boilers, oil and gas boilers, portable generators, oil or solid fuel cookers, gas or paraffin heaters, barbecues (BBQs), clogged chimneys, wood or gas fireplaces, cigarette smoke or any fossil fuel-burning appliances.The sensor within the unit will deteriorate after 10 years, so to ensure you're protected, we recommend you replace the unit after this time. All alarms are calibrated and rigorously tested in-house and are third party tested to receive the BSI Kitemark certification to provide peace of mind. With the alarm memory function, the red LED will flash to provide a visual indication of a previous CO alarm activation. The FireAngel CO-9D shows low level readings down to 10ppm and peak level readings over the last 4 weeks.
