Description

Protect your home from fires with this 230V mains smoke alarm from Kidde. It uses an ionisation sensor to detect fast-flaming fires and has a built in 9V Alkaline battery as back-up. To test the alarm there is a test/Hush button that allows regular testing of alarm function and can be used to temporarily silence nuisance alarms. There is also an indicator on the alarm to show the alarms current status. If you have more than one of Kiddes FireX mains alarm range these can be interlinked; so if a fire is detected in one room all alarms will sound. This smoke alarm has approval from the BSI (British Standards Institution) and is CE tested and certified.About Kidde Founded by Walter Kidde in 1917, a pioneer in early smoke detection and fire suppression, Kidde is the world’s largest manufacturer of fire safety products. Each day, they work to expand their legacy of innovation, providing advanced solutions to protect people and property from fire and related hazards.
