The Safety Siren Pro Series3 Radon Detector is designed to plug into a standard 120 volt household outlet using the attached power cord. The detector may be placed face up on a tabletop, counter, tip, or any flat surface where the ventilation slots will not be blocked. The detector must be kept free of dust. A proper airflow must be maintained through the detector to obtain an air sampling representative of the local enviror4enoment. Do not plug the detector into a wall socket controlled by a light switch.

How to Test

The detector measures radon gas in the air you breathe. You do not want to measure the chemical composition of objects in your home with this device. Remember, the air you breathe is the most important aspect of measuring and monitoring radon gas.

The detector should be placed in the lowest living area of the home in a location where it will not be disturbed. The audible alarm should be able to be heard from areas frequented on a daily basis. A second detector placed in a basement room rarely used, is also a good means to determine the level of radon in the home.

The location of the detector should be at lease 3 feet away from windows, doors, or any other potential openings in the exterior walls. The location of the detector should be at least 1 foot from the exterior wall and at least 20 inches from the floor. No other object should be placed within 4 inches of the detector. After taking air samples for approximately 48 hours, the initial reading will display on the screen.
