First Alert Hardwired Smart Smoke Alarm
A: Hi FirstTimeBuyer, thank you for your question. Yes, you will be able to connect your SC5 to the Google Home App. The SC5 must be enrolled first via the FA App and then can be linked to your Google Home App. You can then just use the GH App to operate it. If using the GH App notifications, you can disable notifications from the FA App. - Maria
A: No, it does not have a light like the nest protect unfortunately.
Q: Is the halo light on all the time? That would be pretty annoying if installed in a bedroom.
A: Hi PhilippeS, thank you for your question. No, the halo light on the SC5 detector is not on all the time. During normal operation, the halo LED remains off, so it won’t disturb you if the unit is installed in a bedroom. - Maria
Q: Does it work with Alexa in addition to Google Home?
A: Hi PhilippeS, thank you for your question. At this time, the SC5 is only compatible with Google Home and our First Alert App. - Maria
Q: Is this a 10-year rated battery?
A: Yes.
Q: Is the battery powered model suitable for operation in an unheated garage in the northern US?
A: Hi Tom, thank you for reaching out!. Our detector is not recommended for use in garages or areas where temperature is colder than 40˚ F or hotter than 100˚F. For more detail, you can look at the section labeled "Where not to install this alarm" on the first page of your installation manual or reach out to our support team at 800-323-9005. We are always happy to help! — Charlie
A: Hi Sobs, thank you for your question. Yes, the SC5 is the replacement for the Nest Protect model 06A (battery powered) and 06C (hardwired AC power models). Order the correct SC5 for your wiring. For US models: SMCO600NV-AC for AC power and SMCO600NV for battery powered. - Maria
