About this item
  • 【2-IN-1 SMOKE & CARBON MONOXIDE ALARM】Equipped with a smoke sensor and carbon monoxide sensor, this combination alarm monitors for both smoke from smouldering fires and dangerous carbon monoxide produced by fuel-burning appliances, helping protect your family from two serious household hazards.
  • 【LOUD AUDIBLE ALARM】The powerful 85 dB siren provides an immediate audible warning when danger is detected. Additional sound and light indicators keep you informed of normal operation, low battery and fault status, so you can respond promptly.
  • 【TEST & SILENCE BUTTON】Use the Test/Silence button to perform regular operational checks. Where permitted by the user manual, the silence function can temporarily mute eligible nuisance alarms. Always follow the supplied instructions when testing or silencing the alarm.
  • 【BATTERY POWERED & SIMPLE TO INSTALL】The battery-powered design requires no hardwiring or electrician. Install the compact alarm on a suitable wall or ceiling in minutes using the included mounting accessories, and replace the battery easily when the low-battery warning sounds.
  • 【STANDALONE MODEL—PLEASE CHECK BEFORE ORDERING】This alarm operates independently and does not support Wi-Fi, an app, a base station or wireless interconnection. Install, test and maintain the unit strictly in accordance with the supplied user manual.

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.
