1. Product Overview
Thank you for selecting the RAD-0102-6 CO2 Storage
Safety Alarm. This monitor is designed to detect Carbon
Dioxide levels in the ambient air to protect employees
and customers. CO2 monitors are required in most
jurisdictions by code. High concentrations of CO2 in
confined spaces are dangerous, and may lead to health
problems ranging from headaches and fatigue to
asphyxiation and death. This monitor has 3 audible and
visual alarm levels with relays that are triggered at 5,000
ppm TWA, 15,000 ppm, and 30,000 ppm and can control
a ventilation fan or signal the fire panel to send an alarm
to the fire department or monitoring company. These
standards meet IFC, NFPA, and NBIC requirements for
monitoring.
RAD-0102-6 CO2 Monitor is cost-effective and includes these features:
1.) Multiple RDU’s can be connected for additional alarm points.
2.) Large digital LCD display clearly indicates the ambient CO2 concentration,
relative humidity, and temperature.
3.) 3 independent relay outputs can automatically control vent fan or be wired to the fire alarm
panel.
4.) Audible and visual alarm indications.
5.) Automatic altitude compensation (can be turned on/off).
6.) 4-20 mA output for offsite monitoring.
7.) 100% clean look by burying all cables in the wall.
8.) Allows for field upgrades with strobe package at a later date.

4. SEU (Main Sensor Unit)
The SEU (Main Sensor Unit) should be placed in a room where CO2 is likely to accumulate, a
room where CO2 is stored, like an area with CO2 beverages.
The large LCD displays the ambient CO2 concentration.
The SEU has “DIAG”, “AL1”, “AL2”,”AL3”, “CO2 CALI”, “RCFS” functions:
“DIAG” function executes communication tests between the SEU and RDU.
“AL1” is a fixed 5000ppm TWA.
“AL2” and “AL3” are two CO2 alarm levels. These alarm levels are adjustable.
- AL2 has CO2 level of: 5000, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%. (AL2 default is 1.5%)
- AL3 has CO2 levels of: 2.0%, 2.5%, 3.0%, 3.5%, 4.0%. (AL3 default is 3.0%)
“CALI” function allows the user to perform calibration, when necessary.
“RCFS” function allows the user to re-set the unit to the original factory settings.
When the RAD-0102-6 detects a CO2 TWA (average in 8 hours) value that exceeds 5,000ppm,
the AL1 (Red 1 LED) will blink and Relay 1 will be triggered.
When the CO2 TWA value drops below 5000ppm (with 5% hysteresis), AL1 (Red1 LED) will stop
blinking and Relay 1 will be inactive.
When the RAD-0102-6 detects a CO2 value that exceeds the AL2 CO2 level, AL2 (Red 2 LED)
will blink, the buzzer will sound and Relay 2 will be triggered.
When the CO2 value drops below the AL2 CO2 level, AL2 (Red 2 LED) will stop blinking, the
buzzer will stop and Relay 2 will be inactive.
If the CO2 concentration continues to rise and exceeds the AL3 CO2 level, AL2 (Red 2 LED) and
AL3 (Red 3 LED) will flash together. The tempo of the flashing and buzzer will increase. RAD-
0102-6 will latch after this event. When the CO2 value drops below the AL3 CO2 level and then
below the AL2 CO2 level, the flashing and buzzer will stop, but the Fault LED will remain flashing.
The RAD-0102-6 must be reset, by means of reset button of RAD-0102-6 (see item L in Section
2 SEU layout) or power cycle the unit.
The Power (Green LED) will light continuously when the power is normally supplied. If the device
is powered by a battery, the Power (Green LED) will flash and battery indicator will appear and
change with the battery voltage.
If the communication cable between the SEU & RDU is not connect well, the communication
cable is loose or disconnected from the (RJ45) connectors, the fault LED of SEU will blink as a
reminder for the user to reconnect the cable. If the communication cable is inserted into the
wrong port on RDU, after about one minute, the “Er7” will flash on the RDU LCD. Please plug
the cables into the correct ports on RDU and the unit will work normally.

5. RDU (Remote Display Unit)
The RDU displays the data from the SEU and provides visual and audible indication that the SEU
is in alarm status. The RDU is NOT an external/second sensor. The RDU is connected to the
SEU with a CAT5 cable. A 25-foot CAT5 cable is provided. Users can source additional cable
lengths as needed. The RDU should be placed where it can be conveniently observed (eye level)
before entering the room/space.
The “DIAG” function can test the communication between the SEU and RDU (see 9.1). Resetting
the RAD-0102-6 CO2 Monitor is only available from SEU.
6. Strobes
The RAD-0102-6 can be equipped with strobes for additional visual alarms. Using CAT5 cables,
connect the strobes to the correct RJ45 ports on the SEU and RDU. If CO2 levels exceed AL2,
the strobe will flash. If the CO2 level exceeds AL3, the strobe tempo increases.
Please visit www.CO2Meter.com for strobe package. Part Number: CM-1026.
7. Power
The RAD-1020-6 comes pre-wired with a 12V power supply that plugs in to a wall outlet. The
12V power supply can be removed and 24V DC can be wired directly to the device through the
terminal block. Please use a 24V DC power converter to properly convert your AC power
source.
8. Installation Instructions
Please carefully remove all items from the package and follow the Step-by-Step Installation
Instructions:
1. Choose a suitable location to install the SEU. Fix the panel holder on the wall with the four
screws. Install the SEU 18-24 inches (45-60cm) from floor and close to the CO2 source.
2. Put the SEU on the panel holder, making sure that they are connected tightly.
3. Fix another panel holder in a suitable location outside the monitored space at eye level. Place
the RDU onto panel holder, and stick the warning signs next to RDU.
4. Route the 25-foot CAT5 cable between the SEU and RDU. CAT5 cable can be run through the
wall/conduit or fixed to the wall using cable clips. Plug the CAT5 cable into the designated ports.
Communication between the SEU and RDU is complete.
5. The RAD-0102-6 has 3 relay outputs connected to the programmed alarm settings. All relays
are normally open/closed dry contacts. Any of the relays can be used to control an external
device (fan, HVAC system, etc.) or can be wired to the fire alarm panel directly. The relays will
trigger when the CO2 concentration exceeds the programmed alarm level.
6. When the power has been connected, The SEU and the RDU will begin to work.
7. Please use the “DIAG“ function to verify the communication between SEU and RDU, the five
LED’s will blink and buzzer will sound on SEU & RDU, after that the communication is ready.
The units will display the same information.

10.5) Calibration using the CO2 CALI function:
1. You will need a gas cylinder of pure Nitrogen (0 ppm CO2).
2. Temporarily cover the buzzer hole on the bottom left-hand corner of the SEU (Main unit) and
bottom right-hand corner on the 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 installed, first inform building occupants that you will be
testing the CO2 alarm for several minutes.
Note: Please pump N2 (zero CO2) into the CO2 Sensor Entry (Item A in section 2) and wait
about 3 minutes before calibration, then execute the “ZEro” calibration.
1. Hold the tubing from the Nitrogen (0ppm CO2) gas cylinder to the CO2 sensor opening (on
the top left-hand corner).
2. Open the gas regulator. Flow rate should be between 0.15-0.50 liters per minute.
3. Wait until the CO2 reading on the SEU settles consistently at or near 0ppm CO2.
4. Press the Mode button 5 times, the “CO2” and “CALI” icon will start flashing on the SEU.
5. Press Enter to view the calibration settings. The SEU screen will now display a flashing
“ZEro” and “CO2”.
6. Press Enter again to begin the calibration. “CALIBRATING” will begin flashing.
7. After approximately 3 minutes, the LCD will display either “PASS” or “FAIL”.
8. If the LCD reads “FAIL”, repeat the steps again. If it displays “PASS”, press Enter. The
display should now show 0ppm.
9. Remove the nitrogen cylinder.
10. Reset the unit by either pressing the reset bottom (bottom right-hand corner with a round
arrow) or power cycling the unit.
11. If your unit fails the “ZEro” calibration, please follow the procedure again before calling
support.
