Ensuring a safe environment in areas where ozone is present is critical. The OA-1 Ozone Alarm is a high-quality, fixed-mount ozone detection and alarm system designed to protect personnel by providing real-time ozone monitoring with audible and visual alerts when ozone levels exceed safe limits. With user-settable alarm points, an auxiliary relay for external system control, and 4-20 mA output, this device is an ideal solution for safety applications.
Key Features of the OA-1 Ozone Alarm
- Red Strobe Light – Provides a clear visual alert when ozone levels exceed the user-set alarm point.
- Audible Alarm – A built-in siren activates when ozone concentrations rise above the preset threshold.
- Adjustable Volume – Simply turn the cover of the siren to increase or decrease alarm volume.
- User-Settable Alarm Point – Customize the ozone concentration level that triggers the alarm.
- Auxiliary Relay (10 Amp) – Can control external devices, such as ventilation fans or ozone generators, automatically when the alarm triggers.
- Optional Display – Shows the current ozone concentration and a 12-hour trend graph for easy monitoring.
- Built-in Fan – Actively draws air past the ozone sensor for real-time detection.
- Multiple Ranges Available – Choose from three different detection ranges:
- 0-0.1 ppm (ideal for ultra-low ozone environments)
- 0-1.0 ppm (for standard safety monitoring)
- 0-10.0 ppm (for high-ozone environments)
- 4-20 mA Output – Provides a linear signal output proportional to the ozone concentration for easy integration into monitoring systems.
- Field-Replaceable Sensor – The OA-1 uses the SM-3 Sensor, which can be easily swapped out without removing the unit from service, reducing maintenance time and costs.

Field-Replaceable Sensor for Easy Maintenance
Unlike traditional ozone detectors that require calibration, the OA-1 Ozone Alarm uses the SM-3 field-replaceable sensor. Instead of taking the unit out of service for calibration, simply swap out the old sensor with a new one. This method reduces long-term costs and minimizes downtime, making the OA-1 a cost-effective and low-maintenance solution.
Advantages of the SM-3 Replaceable Sensor:
- No need to remove the unit from service for calibration.
- Quick and easy sensor replacement in minutes.
- Cost-effective compared to calibration-based alternatives.
Data Logging Capabilities
For users who need to track ozone levels over time, the OA-1 Ozone Alarm is compatible with the DL-3 external data logger. This allows you to record ozone concentration levels via the 4-20 mA output, making it easy to analyze trends, maintain compliance, and improve workplace safety.
Wireless Monitoring & Data Logging Kit
For remote access and real-time monitoring, the Wireless Monitoring & Data Logging Kit can be used with the OA-1. This system connects your ozone detector to the internet, allowing you to:
- Access ozone level data from anywhere using a web-based platform.
- Receive instant notifications via text or email if ozone levels exceed safe limits.
- Improve safety response times by enabling remote monitoring and control.
Why Choose the OA-1 Ozone Alarm?
The OA-1 Ozone Alarm is a reliable, easy-to-use, and cost-effective solution for monitoring ozone exposure in various environments. With its audible and visual alarms, user-settable controls, and optional data logging capabilities, it is an essential tool for maintaining a safe workplace where ozone is present.
