Are you an electrician? Can you fill out your profile?

I did a big favour for a tin basher and now I have him on speed dial for questions.

The HVAC forums wont let electricians on there. I tried in the past when I was doing maintenance.

I'm curious why the OP felt the need to let us know he is hetero.

Why ask an HVAC question on an electrical site?

Is it a control question?

CO2 sensors would be connected to the fire alarm system no?

Even residential CO2 alarms are covered in all fire alarm training as well.
We don't connect to the fire alarm systems, not when they are duct mounted.

I don’t have any HVAC experience but I have connected many CO2 sensors (not duct mounted) to a fire alarm system.
I think you are using a misnomer here.

CO (carbon monoxide) detectors are often connected to a fire alarm system to alert of a dangerous situation, CO2 (carbon dioxide) detectors are most often a part of a DDC building management system to decide when OAD (outside air dampers) and or a HRV (heat recovery ventilators) are put into operation to control IAQ (indoor air quality) standards.

Ahhhhh.

Yes I was not reading and assumed CO detection is what we were talking about.

Thanks Mech
