Product Details:

Keep your family safe and your home protected by using this Google Nest Protect smoke and carbon monoxide detector. It?s a smart smoke alarm that thinks, speaks, and alerts your phone whenever there?s a potential danger.

The alarm has a split-spectrum sensor, which uses two wavelengths to detect smoke from both fast-burning and smouldering fires. If something?s wrong, you?ll know immediately ? it sends real-time alerts to you, and everyone in your family. If the alarm is sounding but everything is under control, it?s quick and easy to silence via the Nest app on your mobile phone.

Gone are the days when you get woken up by a loud beeping when your alarm?s batteries need replacing. This Nest smart alarm will send a message to your mobile instead. You can test all alarms with a tap and be reassured that the alarm tests its sensors and batteries every day. When you walk under the Nest Protect alarm at night, a Pathlight will switch on to help you find your way.

The Nest Protect 2nd Generation Smoke CO Alarm that thinks and can detect both fast and slow burning fires. It can alert your phone and tell you where the danger is. You can also silence false alarms with your phone. All this is a new design from the inside out. It has a split spectrum sensor, tests itself automatically and for up to a decade.

The split sensor uses a 450 nm wavelength of light to detect tiny particles created by fast fires. To reduce false alarms, the Split Spectrum Sensor is shielded against outside light, etched to protect it against dust and encased in a stainless-steel screen. Nest Protect uses both a humidity sensor and an advanced algorithm to cut false alarms from steam by 50%.

In Scotland, the law on fire alarms has changed as of February 1, 2022, and which now requires all Scottish homes to have interlinked alarms. The law places the onus on the homeowner and/or landlord.
