FireAngel Combination Smoke and Carbon Monoxide Alarm for Home - SCB10-R, 10 Year Life, Dual Carbon Monoxide Detector and Smoke Alarm with Test and Hush Button - Combined CO and Fire Alarm - White

Main Highlights

DUAL PROTECTION: This combination carbon monoxide (CO) and smoke detector offers vital protection against both CO and fire risks. The CO sensor alerts you to invisible gas dangers, and the optical smoke sensor quickly 'sees' slow, smouldering fires.

10 YEAR BATTERY: Each 2 in 1 carbon monoxide and smoke alarm for home use comes with a 10 year sealed battery that lasts the alarm's lifetime. When the device needs replacing, it will ‘chirp’ twice and the amber LED will flash twice every 40 seconds.

ADVANCED DETECTION: The advanced optical sensing technology reduces nuisance smoke alarms by 'seeing' thick white smoke as it enters the alarm, while the advanced electrochemical CO sensing technology provides improved CO detection.

DISTINCT ALARM SOUNDS: The dual smoke and carbon monoxide alarm features clear visual indicators and separate alerts for each hazard, allowing you to easily identify the specific danger when the alarm sounds

POSITIONING: Suitable for the landing, hallway, bedroom, living room and dining room; aim to position the combined smoke alarm and carbon monoxide detector as close to the sleeping area as possible on the wall or ceiling.

SAFETY ASSURED: The SCB10-R FireAngel smoke alarm and CO monitor is Kitemark certified, and third-party approved by the British Standards Institute (BSI) to EN 14604:2005+AC:2008 EN 50291-1:2018. It includes a 3-year warranty.

FIREANGEL HOME SAFETY: In addition to our combination CO and smoke alarms for the home, we offer a wide range of other safety products designed to protect you and your family. Choose from smart devices, as well as standard smoke and heat alarms.

EARLY WARNING SMOKE DETECTOR: The Toast Proof Smoke Alarm is less prone to false alarms. The optical smoke sensing chamber works by 'seeing' smoke as it enters the alarm, perfect for slow burning fires with thick white smoke.

ENHANCED CO SENSING: Designed with intelligent sensing technology, the CO alarm's high sensitivity mode activates when it predicts CO levels will increase to or above 180ppm, providing a quicker alert to ventilate.

REPLACEABLE BATTERIES: The SB1-R smoke detector includes a 1-year replaceable battery and a 3 year warranty. The FA3313 Fire Angel CO alarm comes with 2 x 1 year replaceable AA batteries and a 5 year warranty.

ADDITIONAL FEATURES: You can mute the FA3313's low battery warning for 8 hours by pressing the test button whilst the amber light continues to flash. For a false smoke alarm, hold the SB1-R test button for 5 seconds to silence it for 8 minutes.

SAFETY ASSURED: The FA3313 CO monitor holds CE and UKCA marks and is certified to BS EN 50291-1:2018 and BS EN 50291-2:2019. The SB1-R alarm holds both CE and UKCA marks and is certified to BS EN 14604:2005. Suitable for homes in England and Wales.

Meross Carbon Monoxide Detector, Dual Sensor Smoke and Carbon Monoxide alarm, Smoke Alarm for home with Test/Silence Button, 10-Year Battery Smoke Alarm, 85dB Fire Alarm, EN 14604 & EN 50291 Standard

Main Highlights

2-in-1 Function: The photoelectric smoke detector and electrochemical CO sensor work independently of each other. If the carbon-monoxide-detector detects both smoke and carbon monoxide, it sounds first for smoke and then for CO. The CO detector detects both fast and slow-burning fires, minimising false alarms.

10-Year Service Life: The smoke alarm and carbon monoxide detector contains one built-in 3V CR123A battery (not removable) that can last 10 years. You can avoid the trouble of replacing the battery, and it ensures your carbon monoxide alarm is always ready to protect.

User-Friendly Design: The light and simple white round design ensures the carbon monoxide detector blends seamlessly into your home. The carbon monoxide and smoke detector includes a test/silence button (please press the test button monthly to confirm the working status of the smoke alarm). The fire alarm sound is over 85dB at 3 metres and sounds throughout your home; press the test button to silence.

High-Tech: This carbon monoxide and smoke detector has an inbuilt smart chipset. The carbon monoxide alarm is automatically activated when it is attached to the bracket. The LED light is normally green and turns red in an emergency. The smoke alarm for home complies with EN 14604 and EN 50291 standards to ensure reliable quality.

Easy Installation: The battery-operated smoke detector (not wired) can be installed by yourself in 5 minutes without the need for an electrician. The CO alarm is easy to mount on any wall or ceiling with the included screws. Note: Carbon monoxide is lighter than air, so it is recommended to install it at a distance of 30 cm from the ceiling.
