To link or not to link smoke/heat/CO2 detectors?

Worth to link the following? 3 smoke detectors (one on each floor) 1 heat detector in kitchen 1 CO2 detector in boiler room (ground floor) If I don’t link everything: I am sleeping on the 1st floor. What if an alarm goes off in ground or 2nd floor. Can I hear…

Worth to link the following? 3 smoke detectors (one on each floor) 1 heat detector in kitchen 1 CO2 detector in boiler room (ground floor) If I don’t link everything: I am sleeping on the 1st floor. What if an alarm goes off in ground or 2nd floor. Can I hear it? It’s 85dB. If I do link everything: In case the alarm goes off, I won’t know where the problem is since everything will go off. In case of false alarm, I will think it’s a real alarm, because I don’t know where the problem is. Thoughts?

not really necessary; individual alarms help identify source of problem

Yes, but do I hear the alarm in my bedroom then? I don’t wanna get fried while sleeping haha

Thanks a lot for your reply. I am living in The Netherlands. Legally only one per floor is required. The house is built around 17 years ago. All alarms will have their own battery that lasts 10 years. It is not wired. Total costs is less than €150,- for everything from X Sense. I just noticed that for €35 I can buy the Home station and connect all to it. Then connect with phone and with my phone I can see exactly which alarm is going off. Guess this is the best solution to my problems?

Sounds good. Just never assume an alarm is false. Let the emergency response folks make that call

u/xman747x

the idea is you can hear where in the house the alarm is coming from

First, it’s “CO,” carbon monoxide not CO2, carbon dioxide. Second, you want any of these detectors to be located where they will wake you up if they alarm while you are asleep. Bear in mind that CO exposure can make you drowsy too. Putting your CO detector in a presumably closed boiler room a floor away from where you’re sleeping might not be optimal Third, probably not enough smoke detectors. Not sure where you are but in the US it’s common to have one per room, excepting bathrooms Fourth, what false alarms? If they are functioning properly you should assume the alarm is for a good reason Fifth, do you have battery backup? None of these will work in a power outage without battery backup.

Won't hear the ground floor one at all unless your bedroom door is open, might hear the upstairs one faintly depending on how far away it is.

use seperate alarms. by the time a carbon monoxide detector on the ceiling goes off, you are long dead. they need to be at floor level. one per bedroom area. like we have two hallways with bedrooms, so we have two CO detectors, just outside. smoke detectors on the ceiling, one per bedroom, just inside, one of each in living space in living areas https://support.firstalert.com/s/article/Proper-placement-for-smoke-alarms-CO-alarms-and-fire-extinguishers
