replacing smoke alarms

Featured Replies

My smoke alarms need to be replaced, I have the ei141 and ei146.

Do I need an electrician to replace the ei140 range with the ei160 range?

My Dicon NL3602 fire alarm has stopped working.  After a lot of research I ordered an EASICHANGE SBBRKSM 660MBX/760MBX/770MBX  from Safelincs which arrived with me today 14/03/2026.  I am now concerned I may have ordered the wrong easy replacement and may have to change it for the one you may recommend.

I looked on the safelincs website, the EASICHANGE SBBRKSM is listed as a replacement for "Deta" smoke alarms NOT "Dicon" smoke alarms that you have, so yes, you have ordered the wrong item.

I would change the detector to an Aico brand Click me 

As the whole thing is to be replaced I suggest you get a competent person to do it for you, also if you have any other smoke alarms change those too. (The ones I linked to are interconnectable)
