Hi Henrik,
I’m a test engineer at Sensereo. Sorry to hear you’re having trouble commissioning the devices.
This setup should work, so we’d like to help determine whether this is related to the network configuration or to the devices themselves.
Could you please contact our support team at [email protected] ? If you could include some details about your setup (HA version, OTBR, Android/iOS device, and any screenshots or error messages), our team will be happy to help you troubleshoot the issue.
Hi Marius,
I’m a test engineer at Sensereo. Thanks for raising this question—it’s a very reasonable one, and it’s something we also considered during the product design.
You’re right that smoke alarms and CO alarms have traditionally had different installation recommendations, which is why some users still prefer separate devices.
For combination alarms, however, the product is evaluated and certified as a complete unit rather than simply combining two independent detectors. Our MSC-1 has been tested and certified against the applicable smoke alarm and CO alarm standards, and the installation instructions are part of that certification process.
In other words, the recommended installation location for the combination alarm is validated as part of meeting both certification requirements, rather than simply applying the installation guidance for two standalone devices independently.
We also understand that some users prefer separate devices for exactly the reasons you mentioned. That’s why, in addition to the MSC-1 smoke & CO alarm, we also offer the MS-1, which is a dedicated smoke alarm, allowing users to choose the solution that best fits their home and local requirements.
Thanks again for bringing up the question—it’s a great discussion point.
Hi Isabel,
by now, we know you are a test engineer at Sensereo …
in all honesty, I feel the posts of this account are purely AI generated, the form, content and logic seem 100% automated and repetitive.
Not sure this complies with the new AI guidelines that were posted yesterday, and complies with the WWHA idea at all.
besides that, my point was not that this device might not be certified.
my point is that a CO alarm can never be safe when combined with a Smoke alarm and attached to the ceiling.
that is not tradition. that is physics.
as such, these devices should not be advocated to be life savers at all, and because of that, should not be in the WWHA program.
agreed on that
Fair point. I think I misunderstood your main concern in my previous reply and focused too much on certification.
I looked into the placement question again. CO doesn’t necessarily need to be detected lower on a wall. It mixes with the air in the room, and EN 50291 does allow CO alarms to be installed on the ceiling in appropriate locations. This is also why smoke and CO combination alarms designed for ceiling installation exist.
Of course, placement still matters. Things like distance from fuel-burning appliances, doors, windows and ventilation all need to be considered. For a combination alarm, the important thing is whether both smoke and CO detection meet the required performance at the mounting position specified by the manufacturer.
So I do understand your concern better now. I just don’t think being mounted on the ceiling by itself means that a CO alarm can’t work safely.
And regarding the AI point, that’s fair too. Part of my job also involves helping our support team with technical and testing-related questions, and I’ve got into the habit of using AI to help organize and polish what I want to say in English before posting it publicly. The technical information and opinions I’m sharing here are mine, but I can see how that made some of my replies sound repetitive and overly structured. I’ll keep that in mind for future replies.
