Smoke alarm phone alert when away
Updated: October 2026
You want a smoke alarm phone alert when away if something starts at home. That push reaches you only while the alarm, the router and the broadband stay on one path. It does not replace the ceiling sounder, and it does not call the fire and rescue service. Peter F. read the amazon.co.uk listings kept on 19 October 2026 and did not run a lab test. A qualifying purchase can earn a commission at no extra cost to you. Models are on the [smart home smoke alarm comparison](/hub/fire-protection/smart-home-smoke-alarm).

What the phone can tell you
The alert is an app push for smoke and, where the listing says so, a fault or a low battery. It is not a text from the fire service. Several X-Sense listings say the app can be shared with up to 12 accounts. Norfolk Fire and Rescue says an alert on one phone can be missed, and advises at least two devices. The XUK, CNBINGO and AEGISLINK name an app and do not state a share count. A push does not replace the button test.
What dies when the Wi-Fi dies
The remote alert needs 2.4 GHz and a path to the internet. Which?, on 12 May 2026, says the alarm can still sound without Wi-Fi. Lose the broadband and the phone stays quiet. Pairing is on the how to set up a WiFi smoke alarm page.
An SBS50 kit can still sound together if the hub loses power or the internet. The XS0B-iR, SC07-WX and XP0A-iR do not interlink, so one of them is one sounder. A gas emergency in Great Britain is 0800 111 999.
Who is still in the house
A phone in another town does not wake someone behind a shut door. If nobody would hear a sounder, ask the fire service about a home visit or a specialist alert. The link choice is on the WiFi smoke alarm vs interlinked page.
An XS0B-iR in the hall can share a push and still leave the warning behind a bedroom door. A hub kit that states interlink tries to sound in that bedroom too.
A landlord, a hush button, and 999
In England the landlord’s duty is a smoke alarm on each living storey, a check at a new tenancy, and a repair after a reported fault, as soon as reasonably practicable from 1 October 2022. The GOV.UK booklet does not ask for an app. Silencing a push is not that repair.
The FS31 and SD11-MR31 list app silence. Use it only once you know the room. If it is a fire, call 999. These listings do not call the fire and rescue service. A missing alert because the alarm never joined 2.4 GHz is a setup failure, not a clear house.
Common questions
Will a smart smoke alarm text me when I am away?
It can send a phone notification while the alarm is on 2.4 GHz and the broadband path is up. On this shelf that is an app push, not a text from the fire and rescue service. X-Sense listings that state sharing, including the FS31 and the SC07-WX, say up to 12 accounts can receive it. The XUK and the CNBINGO PG-S11 name an app and do not state a share count. The sounder at home is separate from whether your phone buzzes.
What happens to the phone alert if the Wi-Fi or the broadband drops?
The remote notification stops. Which? says the alarm can still sound without Wi-Fi, and that the connection is for the alert on your phone. A hub kit whose listing says the alarms are interlinked, such as the FS31 with its SBS50, can still sound together if the hub loses power or the internet. A single that says it does not interlink, such as the XS0B-iR, has only its own sounder left.
Can a landlord rely on the app instead of a smoke alarm the tenant can hear?
No. In England the duty is a working smoke alarm on each storey used as living accommodation, a check at the start of a new tenancy, and a repair after a reported fault. The GOV.UK booklet does not require an app. A landlord still owes that alarm while the tenant is there. Reading a push from another town is not a substitute, and hushing it from the phone is not a repair.
Should I silence an alert from the app while I am out?
Treat the notification as a reason to find out what is happening, not as a mute switch. The FS31 and the SD11-MR31 list app silence. If you use it before you know the room, you may quiet a real alarm in a house you cannot see. If it is a fire, call 999. The listing has not already called anyone for you.
Does the alarm call the fire and rescue service for me?
No. These captured amazon.co.uk listings do not call the fire and rescue service. A phone alert tells the accounts that are signed in, and only while the connection holds. A real fire is a 999 call by a person. A carbon monoxide warning on a combination alarm such as the SC07-WX is still a local sounder and a push. A gas emergency in Great Britain is 0800 111 999.
Will the phone wake someone who is asleep in the house?
No. Your phone is not a second sounder inside the house. The person asleep needs an alarm they can hear, and Fire Kills notes that some children may not be woken even by the smoke alarm itself. A parent’s push on another network does not close that gap. If nobody would hear a sounder, ask the local fire and rescue service about a home visit or a specialist alert.
