Designed to measure pressure differential changes, the Radon Alarm notifies homeowners when their Active Soil Depressurization radon reduction system fails.

The Radon Alarm measures the suction pressure - not the radon levels - of the Active Soil Depressurization (ASD) system. It exceeds AARST requirements by including a clear & distinct audible notification and a visual light notification that is vividly observable— consisting of green, yellow, & red LED lights. 

Additionally, this alarm gives mitigators added control by utilizing two (2) dip switches to set audibility function and alarm delay time. No pre-installation action is required if the factory default settings meet the application requirements.
