Q: Can I turn off the night light feature?
A: The LED lights on the Onelink alarm not only provide a nice glow to light up your route, but they also indicate that the alarm is receiving AC power. You can adjust the brightness level of the nightlight through the Onelink app. When you disable the nighlight two LEDs will glow green on the Onelink alarm letting you know that you have AC power. If the LED is turned off, it indicates your alarm is running off of battery backup.
Q: Why can't I change my nightlight color to red in the Onelink Home App?

Q: Does this device support Alexa?
A: Alexa voice services are not supported, so you can't talk to Alexa with this unit. However, if you have an Echo or similar Alexa-enabled device, you can use Onelink Alexa skills to check in on your detector. The nightlight on the hardwired alarm can also be controlled with Alexa.
Q: I just installed my Smart Smoke & CO Alarm. Why does it keep beeping and chirping?
A: Sometimes, alarms may beep or "chirp" to let you know that something isn't right. A chirp is quieter and more intermittent than a regular alarm. Chirping is typically caused by improper mounting, a low battery, or alarm end-of-life.
