Alarms are mandatory now on radon systems All,
To be clear about what appears to be a general misunderstanding, the active notification monitor is NOT required to be audible; as you can see in Section 9.2.2 of the Standard, it says, “active visual and/or audible notification in the event of ASD fan or other mechanical failure.” A blinking light for example, would not awaken the occupants at 3 AM.
Also, for those asserting the Mitigation Standards Committee does not include adequate representation of radon mitigators, the committee includes Bill Broadhead (PA), Tony McDonald (OH), Aaron Fisher (PA), Fred Ellrott (CA), Kyle Hoylman (KY) and James Fraley (GA), all of whom are active mitigation contractors.
Finally, while they do vary in price, there are multiple products on the market that would meet the requirement.
Now that said, the Standards Consortium Executive Stakeholders Committee (ESC) is scheduled to convene Friday Dec.18th to discuss the change requests submitted. After that, the Standards Management Committee will review the matter from a different perspective.
Thanks for the discussion!
