Nest Protect False Alarms and Failed Smoke Sensor
Why is my Nest Protect sounding false smoke alarms, and my Nest app says ‘The smoke sensor has failed’?
Dusting your Nest Protect
All photoelectric smoke alarms can be impacted by dust. So it’s important to keep your Nest Protect free of dust during the installation process and to clean it if dust is building up. Nest Protect constantly monitors its sensors, to ensure that they’re working properly, so if dust interferes with the smoke sensor Nest Protect can let you know. But it’s still important to keep an eye out for dust build-up to help keep your Nest Protect clean and working properly.
There are two signs that dust may have made it into the smoke chamber:
- Nest Protect begins to chirp and the Nest app says “The smoke sensor has failed”.
- Nest Protect sounds a Heads Up or Emergency Alarm saying there’s smoke, even though there isn’t.
Nest takes steps during the manufacturing process to ensure that your Nest Protect remains dust-free. We also package it with a dust cap to keep dust out during the shipping process.
However, dust can get into your Nest Protect in several ways. For example, removing the old smoke alarm during installation can stir up dust. This is especially true with wired Protects which have wires running through the wall or ceiling. Dust can also accumulate on your Nest Protect over time, like it can on your furniture and other appliances in your home.
