Calibration Procedure: RAD CO2 Safety Alarms

This is a more detailed explanation of the calibration procedure found in the

manual. Check your state or local code for calibration schedule requirements.

At a minimum, you should calibrate at least once a year.

There are 2 different calibration procedures depending on the altitude at which

the device is to be used:

1. 0 ‐ 3,000 ft. (900m): Perform Zero Calibration and Span Calibration.

2. 3,000+ ft.: Perform Zero Calibration only.

Before You Begin

1. For Zero Calibration, you will need a gas cylinder of pure nitrogen (0 ppm

CO2). For Span Calibration, you will need a 2

2. Temporarily cover the buzzer hole in the upper right‐hand corner of the

SEU (sensor unit) and RDU (remote display unit) with a small piece of

masking tape to minimize the alarm sound during calibration.

3. If calibration is to be performed in‐situ, first inform building occupants that

you will be testing the CO2 alarm for several minutes.

4. Attach included tubing between the gas cylinders and the SEU calibration

port as follows:

a. RAD‐0102SX2 – Connect the tubing to the supplied plug and secure it

over the air entry / calibration port on the front of the SEU.

b. RAD‐0102/RAD‐0200 – Connect the tubing to the calibration port on

the bottom of the SEU.

A: RAD‐0102SX2

cylinder of 4% CO2.

B: RAD‐0102/RAD‐0200
