How to replace smoke alarm unit and battery

It is essential to replace smoke alarm unit and a battery at regular bases. You are more than twice as likely to die in a fire at home if you haven’t got a working smoke alarm. Smoke alarms are the easiest way to alert you to the danger of fire, giving you precious time to escape. They are cheap, easy to get hold of, simple to install and maintain.
You should change the batteries once a year (unless mains powered or fitted with a ten-year battery) and replace the whole unit every ten years. The mains powered alarms, which have battery back-up in case of a power cut, need to be installed by a qualified electrician. Still, you can change both, the battery or the unit yourself. It is very easy and only takes a few minutes.

To keep your smoke alarms in good working order, you should maintain it at regular bases:
- test them regularly (ideally once a week but at least once a month), by pressing the test button until the alarm sounds.
- change the batteries once a year (unless mains powered or fitted with a ten year-battery).
- replace the whole unit every ten years.
- clean your smoke alarms every three months by using the soft brush of your vacuum cleaner to remove any excess dust.

Showing exactly how the alarm was held in by the latch really was a 10/10 move. Solved my issue

is it necessary to turn off the power supply? will it beep if i don’t?

[@k-nemo]

If you do not turn off the power before replacement, it will work the same. I show turning it off because it is more professional and safer.
