How to Wire OS-6 Ozone Monitor to Remote Alarm Panel for O3 Safety Monitoring

The EcoSensors OS-6 Ozone Monitor has a safety control relay built in that is set to activate above the ozone human safety limit of 0.1 ppm. When this relay is wired to the Remote Alarm Panel (RAP-1), a loud audible alarm and flashing light will activate when ozone levels go above 0.1 ppm. This blog explains how to wire the RAP-1 to the safety control relay on the OS-6 Ozone Monitor.

Step 1: Remove the front panel on the OS-6.
Step 2: Insert tip of RAP-1 free cable through one of the nipples on the bottom of the OS-6 monitor.
Step 3: Locate the control relay labeled “ABOVE 0.1 PPM.” Connect the red wire to the Normally Open (N/O) terminal and the black wire to the Common (COM) terminal.
Step 4: Replace the OS-6 front panel.

The OS-6 is now wired to the RAP-1. When mounted on a wall and powered on, an audible and visual alarm will now activate when the ozone levels are above the human safety limit of 0.1 ppm.

Ozone Levels Below 0.1 PPM – Alarm Not Activated
Ozone Levels Above 0.1 PPM – Alarm Activated

Ozone alarm in use, audible and visual

Remote Audible Alarm Panel (RAP-1) is Activated by OS-6 Monitor Relay when Ozone is above 0.1 PPM

RAP-1 Audible and Visual Alarm Activates when Ozone Levels are above 0.1 PPM

In this video the RAP-1, which is a remote audible / visual alarm, is wired to the safety relay switch in the OS-6 Ozone Monitor, which is set to trigger above a 0.1 ppm ozone level. According to OSHA, the exposure limit for workers is 0.1 ppm for 8 hours per day. This relay is permanently programmed to always activate above 0.1 ppm ozone levels.

The decibel levels on the RAP-1 range from 92-103 dBA. The volume can be adjusted by turning the little black dial on the RAP-1 (shown in the video). The RAP-1 light and audible alarm are activated the entire time the OS-6 reads above 0.1 ppm ozone. As the ozone levels drop, the readings drop and result in the flashing light and audible alarm stopping after the reading goes below 0.1 ppm ozone.

Both devices can be purchased through our website. Each product is linked to below:

Demonstration of the C-30ZX ozone monitor response speed and alarm function

The C-30ZX ozone monitor is a fixed mount device that will measure ozone from 0-0.14 ppm in 0.02 ppm increments.  This monitor features an internal relay and audible alarm.  The internal relay is user settable at any level from 0.02 – 0.14 in 0.02 ppm increments.  This relay can be used to indicate a remote alarm or shut-down the ozone generation source.  The audible alarm will also sound simultaneously when the relay is set-point is triggered.

The video below displays the response time and the audible alarm triggering.

The EcoSensors C-30ZX is a wall-mounted ozone detector with an instant LED readout, audible safety alarm, and relay switch. The range of ozone measured by this meter is 0-.14 PPM. The main purpose of this sensor is for personnel safety, as 0.14 PPM ozone is the maximum exposure limit allowed by OSHA during an 8-hour work shift.

The C-30ZX has a rapid readout response to changes in ozone levels. Notice how quickly the LED light readout indicates an increase in the ozone level as the sensor moves near the ozone generator. Then, as it moves away, notice how the LED lights almost instantly reflect the lower levels of ozone.

The C-30ZX has an audible alarm that can be switched on. In this case, the alarm is set to sound at .1 ppm. The alarm can be manually switched off – or, it will also stop sounding as soon as the ozone levels are below the alarm set point.

Introduction to the C-30ZX Ozone Monitor

The C-30ZX ozone monitor is a fixed mount ozone detector with a control relay and audible alarm designed to measure ozone from 0-0.14 ppm of ozone in 0.02 ppm increments.  This is a great monitor to use for ozone safety applications where the OSHA 8 hour TWA limit is the primary concern.  The video below shows the basic functions and operation of the C-30ZX ozone monitor.


The EcoSensors C-30ZX Ozone Meter is a fixed monitor with an audible safety alarm and a relay switch. This monitor detects ozone in the range of 0-.14 PPM, which is the OSHA safety limit for ozone exposure during an 8-hour work shift.

The ozone level is indicated by an LED readout, which at the low level is green, at the mid-ozone level is yellow, and at the top of its range, 0.14 ppm, is red to indicate danger. The audible safety alarm can be switched on or off. The C-30ZX Ozone Meter is powered on by plugging it in. The only way to power off this detector is to unplug it. The C-30ZX Ozone Meter is designed to be mounted, plugged in, and powered on continuously. It does not have a battery. The calibration certificate is included in the package. The calibration certificate includes the date of calibration, the data involved in the calibration process, and the serial number of the ozone detector unit. This ozone meter should always be powered on for 24 hours before using it for an accurate ozone detecting. The warm-up phase allows the oxidation to burn off the ozone sensor. Once the oxidation has burned off, the sensor can accurately detect ozone.

The C-30ZX monitor reads ozone from 0 – 0.14 ppm and indicates ozone levels with LED bars that illuminate as the ozone levels. 0.1 ppm is the 8-hour OSHA exposure limit for ozone making the C-30ZX an ideal monitor for measuring low-range ozone levels for safety.

Ozone Sensor SM-X

The SM-X ozone sensor was a replacement sensor for the OS-4, OS-6, and A-22.  However, the SM-X is no longer in production and is now obsolete.

SM-X Replacement Sensor

The SM-6 also used the SM-X as a replacement sensor and also no longer available for purchase.

SM-6 with SM-X

The replacement ozone sensor SM-X (also known as the SM-X-20 or SM-X-2) was paired with EcoSensors OS-4 Ozone Switch, OS-6 Ozone Controller, and A-22 Ozone Monitor. The following options are now available instead:

A-22 Ozone Monitor

A-22 Ozone Monitor

The A-22 is obsolete and there is no replacement sensor option available.  We recommend the following as comparable ozone monitor options to replace your A-22:
D-16 with Ozone 0-20 ppm – https://www.oxidationtech.com/d-16-gas-detector.html
S-300 with EOZ 0-10 ppm – https://www.oxidationtech.com/aeroqual-series-300.html

OS-4 Ozone Switch & OS-6 Ozone Controller

OS-4 Ozone Switch

OS-6 Ozone Controller

The OS-4 and OS-6 Ozone Detectors can be upgraded to use the SM-7/SM-EC electrochemical sensor as an ozone replacement sensor to the SM-6/SM-X.  The new SM-7 will need to be connected to the OS-4 and OS-6 via the wired cable.

SM-7/SM-EC Ozone Sensor

There are two range options for the new SM-7/SM-EC sensor: 0-20ppm or 1-50ppm.  Both range options can be used with the OS-6, but only the 0-20ppm can be used with the OS-4. After you have upgraded to the SM-7/SM-EC then only replacing the SM-EC sensor that’s inside of the SM-7 needs to be done for future sensor replacement.

SM-EC sensor module

The SM-7/SM-EC ozone sensors should be replaced annually as the sensor calibration is good for up to 1 year.

Feel free to contact us with any questions that you have about the SM-X ozone sensor being discontinued.

What Happened at the IOA Today?

On Monday, August 20 the International Ozone Association (IOA) hosted an ozone process workshop giving an overview of ozone and Advanced Oxidation Processes (AOPs).   Seven presenters representing various research organizations and water treatment operations around the country reviewed the basics of AOP fundamentals and considerations for safe and successful process operation and maintenance.  Four companies set up materials for practical, hands-on instruction in feed gas, ozone generator and destruct repair and maintenance, ozone mass transfer, and ozone safety and monitoring.  The discussion and problem solving generated by these presentations served everyone from the large treatment facility to specialized applications such as medicine, food production, or ground water remediation.  I am very excited about this growing industry and will share some of the ideas and information that I am learning as someone new to the industry.
