About this item
  • 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.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
