Smoke & Carbon Monoxide Alarm Duo

CO Smoke Alarm 3 Year Warranty Battery included

Product description

This home safety duo offers essential protection against carbon monoxide and fire. The CO alarm detects invisible gas threats, while the optical smoke alarm responds quickly to slow, smouldering fires.

  • Smoke detector: The smoke sensing chamber ‘sees’ smoke as it enters the alarm, making it ideal for slow burning fires with thick white smoke and less prone to false alarms.
  • Carbon monoxide detector: This portable CO alarm can be wall mounted or used free standing. It detects invisible CO hazards and emits a loud 85 dB alert, providing essential protection at home or on the go.
  • The SB1-R smoke alarms use a 1 year replaceable battery, while the FA6813 carbon monoxide alarms include 2 AA replaceable batteries.
  • The FA6813 CO monitor meets EN 50291-1:2018 and EN 50291-2:2019 standards, and the SB1-R fire alarm complies with EN 14604:2005+AC:2008. Both UKCA certified.

Carbon Monoxide is produced when fuels burn incompletely – this could be from a boiler, gas fire, oven, log burner or a blocked flue or chimney. It can also travel through walls from adjoining properties, so as well as having an alarm next to appliances in your property we would also advise you to have one in living spaces and bedrooms. To help prevent a Carbon Monoxide leak we advise getting your appliances regularly serviced by reputable engineers who are gas safety registered.

See the installation instructions in the product box or product page for installation instructions.

When a Carbon Monoxide alarm is triggered, it will emit an alarm sound consisting of 4 loud beeps and a break repeated until the sensor is clear of Carbon Monoxide gas.
