Sorry for the "late reply" (The way this forum works, all new posts are held for review and released on a Monday)

The Deta 1151 is obsolete and has been for a number of years. As they have no user serviceable parts, I would suggest you change it, as you are changing one, you should change all of them. I recommend the Aico brand Click me as these have a baseplate with dedicated (colour coded) space for the cables, very easy to install, have been around for many years (with no change in baseplate, unlike some.)

Thanks for the advice. Have I understood that the Aiko brand can be used as a direct replacement of the Deta 1151, avoiding the need for me to replace the baseplate? 

Not that replacing the baseplate is a big deal, but if I can avoid it, why not? 

If so, I guess it answers the question that has been on my mind - when replacing a wired interlinked network of smoke/heat detectors, must I stick to the same brand as existing units?

I guess the answer is no, or is it "it depends"? And if so, what do I need to bear in mind? 

Thanks!

Hello Cri, you have miss-understood. I never said the Aico smoke alarm baseplate is compatible with the Deta Brand. I said

Other manufacturers change the design of their smoke alarm and change the design of the baseplate accordingly. Aico have changed their smoke alarm design (slightly) and brought out new alarms BUT they all use the same baseplate

 

For clarification, I have attached a picture of an Aico baseplate and another brand of smoke alarm baseplate. When changing a smoke alarm that is interlinked with other alarms you should change all of them at the same time to the same brand as this avoids any compatibility problems and gives the assurance they will all sound when they need to.  The other thing to consider is that most smoke alarms require an optional baseplate to be ordered, Aico alarms do not require this as it is included in the box and is part of the alarm.

I should also point out that when mounted to their respective baseplate most smoke alarms are deeper than the Aico
