CO2METER COM RAD-0002-ZR Oxygen Deficiency Safety Monitor User Manual

Product Description

Thank you for selecting the RAD-0002-ZR Oxygen Deficiency Safety Monitor.
This monitor is designed to protect customers and workers, anywhere bulk Nitrogen or other inert gases are used or stored
Today, O2 alarms are required in many local state jurisdictions to meet fire codes. The RAD-0002-ZR is designed specifically to meet code requirements for O2 monitoring safety. The Remote Storage
Safety 3 Alarm constantly measures and monitors enclosed areas for lower than normal levels of oxygen gas.
If a gas leak occurs, visible and audible alarms will sound on the sensor unit and on the remote display

• to warn you and your employees.

The RAD-0002-ZR Oxygen Deficiency Safety Monitor is cost-effective and has many features:

• Separate SEU (Main Sensor Unit) and RDU (Remote Display Unit) allow you to see warning before entering an enclosed Up to 3 RDUs can be used.
• Large digital LCD display clearly indicates the ambient O2
• Relay outputs to control external
• Audible and Visual Alarm Indications at three separate alar
• Ability to add strobes or strobe towers for additional

NOTE: All the necessary mounting hardware (screws, mounting brackets, power supply strip) are included.
All you will need is standard screwdriver, for basic installation.
*There are 3 additional universal power plugs included, so as the system can be installed worldwide.

Installation Steps

1. Choose a suitable location near a wall outlet to install the
2. To install the SEU (Sensor Unit) start by making a mark about 12 inches off the floor or at eye level depending on the

Please ask CO2 Meter specialist for clarification.

3. Screw the mounting bracket into the wall where you placed your If you are using the wall adapter, mount the sensor unit close to a wall outlet. (Make sure it is mounted in an area that it will not accidentally get hit by boxes or heavy machinery).
4. Attach one end of the ethernet cable to the SEU (Sensor Unit), then slide the Sensor Unit onto the mounted bracket on the wall. 5. Plug in the wall adapter – the SEU (Sensor Unit) should automatically turn on and perform a self-check.
5. Securely attach the safety strap over the power supply, to ensure it does not become accidentally
6. The Green light should appear and show that the SEU (Sensor Unit) has
7. Over the next few minutes, all lights will flash, and resort back to green. This means the O2 level matches the ambient O2 level in the room and provides you with a precise, accurate percent O2 reading.

Next, the Small Remote Display Install

1. Make a mark for the RDU (Remote Display Unit) outside the room where the SEU is and CO2 is stored. Screw the mounting bracket where the mark is. (Should be mounted at eye
2. Plug in the other end of the ethernet cable into the back of the RDU (Remote

Display Unit)

1. Mount the RDU onto the bracket on the wall, the input on the Remote Display Unit should be connected to the output on the SEU (Sensor Unit).
2. Place the warning signs that came with the device on the wall directly next to the ( The signs should be visible ).

Perform a Test

1. To test if the monitor is operating correctly, you can do a simple Normal Indoor O2 Levels is about 21%.
2. To test the device, simply apply pure Nitrogen on the hole located on the top right corner of the
3. *Verify that the alarms are sounding, and the lights are flashing, on both the SEU and
4. Now you know the monitor is working, the alarm will stop once the O2 returns to a normal

(You can also press the reset alarm button on the SEU to silence the alarm.)

Installation Example:

Installation Connector Options

1. For new build installations, the sensor unit can be powered by

Power+24VDC

2. 4~20mA outputs are included for offsite CO2 monitoring
3. In the case of a power outage, the 6VDC Battery Backup can be installed to retain the alarm
4. If you have more than one door, in the CO2 Storage Area – you can also purchase additional display units (up to three RDU’s can be displayed to a main SEU unit – up to a maximum of 300 ft.
