I have an ERV unit that needs 4 smoke duct detector 2 of them are for supply and return. I am clear about the airstream with those. Then I have one for exhaust air and the other for outside air. I am not clear where to face the sampling tubes holes on those. Can you explain how and why please.
Can you do a video explaining NFPA 72 - 12.6 - 12.7. Simply explaining it as far as how you understand it. Maybe making it easier to understand. I'd really appreciate it.
Thank you for making these videos , so helpful and your teaching style is very clear and makes it understandable.
