Q: Do these replacements to the nest protect also have the ambulance pathway light that comes on when you walk underneath them I help guide you in the evening?

A: Hi! Thank you for reaching out. The SC5 Smart Smoke & CO Alarm does not include a motion sensor or the Pathlight feature, so it won’t light up your path at night or function as a night light. That said, this feature is currently being considered for future versions, so stay tuned for updates! If you have any other questions, we’re happy to help.— Charlie

Q: Will it mount on a Nest protect mounting plate?

A: Hi JimM, thank you for your question. Yes, the SC5 detectors are compatible with Nest Protect mounting plates. They can be mounted directly using the existing plate. Please note that the hardwired version of the SC5 may require a plug in adapter, which is included in the package when purchasing a new unit. - Maria

Q: Are these products compatible with Apple HomeKit?

A: undefined

Q: What's the battery life on these?

A: Hi Chris, thank you for your question. Battery life will vary depending on the model and installation environment, but here are the specifics: For the battery-powered SC5, the expected battery life is approximately 4 years under normal conditions, assuming there are no frequent alarms. This model uses six Duracell or Energizer 123 lithium batteries, which should be replaced when the device signals low battery or after the 4-year mark. For the hardwired SC5, the battery serves as a backup power source in the event of a power outage. Under typical conditions, where AC power remains consistent, the backup battery is designed to last the life of the product and generally does not require replacement during that time.— Charlie

Q: Hello, do these detectors give a warning first for smoke like the Nest, or does it go right into full alarm activation?

A: Hello, RJ. The SC5 does not give a "heads up" alarm for minor smoke incidents like the Nest Protect. In case of smoke, the SC5 will go into alarm mode and announce the location of the place of origin as well as send push notifications to your app. - Maria

Q: I understand this alarm is integrated with Google Nest Protect so that when one alarm goes off all will go off. I am wondering if it will also announce specifically which room/alarm the detected the disturbance? Thank you.

A: Hi mdisaware, thank you for reaching out! During an alarm, the SC5 can announce the location of the originating alert if a name was setup in the app, but this feature is supported only between SC5 and Nest Protect devices. Other wired interconnected alarms will still respond but will not announce locations. When an alarm is triggered, all interconnected detectors will respond, but you’ll only receive a push notification, banner, and full-screen alert from the device that originally detected the issue. If multiple detectors detect issues, each originator will send its own full alert.— Charlie

Q: Does it have a motion light?

A: No, it has no convenience features. Kind of a bummer.

Q: are these controllable through the Nest app, or do I need to start over with google Home?

A: I think you will be obligated to the Google Home App in the very near future, even if First Alert now works in the Nest Protect App.
