When it comes to human safety in environments where ozone levels need to be carefully monitored, the OA-1 Ozone Alarm is a top-tier solution. This fixed-mount device is designed to keep your workplace safe, providing both visual and audible alerts when ozone levels exceed your set safety threshold. With its highly customizable features, the OA-1 is an essential tool for environments where precise ozone detection is crucial.
Key Features of the OA-1 Ozone Alarm:
- Audible and Visual Alerts: The OA-1 is equipped with a bright red strobe light and a loud audible siren, both of which activate when ozone levels surpass the user-set alarm point. The volume of the siren can be easily adjusted by turning the cover, ensuring that the alarm is appropriately loud for your specific environment.
- User-Settable Alarm Point: You can set the exact ozone level at which the alarm will trigger. This ensures you have full control over the safety threshold, allowing you to set a level that meets the specific needs of your facility.
- Auxiliary Relay for External Control: The built-in 10-amp relay triggers simultaneously with the alarm, enabling you to control external devices like fans, ozone generators, or other safety equipment. This automation ensures swift action in response to elevated ozone levels.
- Ozone Level Display & Trend Graph: An optional display shows real-time ozone levels and presents a colorful, 12-hour trend graph, helping you track changes and understand how ozone levels fluctuate over time.
- Built-in Fan: The OA-1 has a fan that actively draws air past the ozone sensor, ensuring continuous monitoring and timely detection of changing ozone levels.
- Multiple Ranges Available: The OA-1 offers three separate measurement ranges, making it flexible for various settings:
- 0-0.1 ppm: Ideal for low-level ozone environments.
- 0-1.0 ppm: Suitable for standard industrial applications.
- 0-10.0 ppm: Best for high-level ozone detection.
- Field Replaceable Sensor: One of the OA-1’s most convenient features is the SM-3 sensor, which is field-replaceable. This means you can change the sensor without removing the unit from service, minimizing downtime and ensuring continuous protection.
Specifications:
- Range: Three options available (0-0.1 ppm, 0-1.0 ppm, 0-10.0 ppm)
- Resolution:
- 0.01 ppm for 0.1 and 1.0 ppm ranges
- 0.1 ppm for the 10.0 ppm range
- Display: Graphic display showing real-time ozone levels and a 12-hour trend graph
- Response Time: 8 seconds
- Measurement Principle: HMOS (Heated Metal Oxide Semiconductor) sensor
- Size: 11″ long x 4.5″ deep x 8″ wide
- Weight: 1 lb
- Power Requirements: 12 VDC at 300 mA, with 120 VAC to 12 VDC adapter included
- Relay Outputs: 10-amp relay for external control
- Analog Output: 4-20 mA output linear with ozone level
- Calibration: Replace sensor annually for optimal performance
Field Replaceable Sensor: SM-3
The OA-1 Ozone Alarm uses the SM-3 sensor for ozone detection, which can be easily replaced every 6 months to a year, ensuring continuous monitoring accuracy. The replacement process is simple and cost-effective, as replacing the sensor costs about the same as calibrating traditional sensors. This makes the OA-1 a more economical choice over time compared to other sensors that require both calibration and eventual sensor replacement.
Data Logging Capabilities
For those needing to log ozone levels over time, the OA-1 is compatible with external data loggers like the DL-3. This allows you to record data using the 4-20 mA output signal, enabling long-term tracking of gas measurements. Data logging is essential for compliance, safety audits, and performance monitoring.
Wireless Monitoring & Data Logging Kit
Take your monitoring system to the next level with the Wireless Monitoring & Data Logging Kit. This kit connects your OA-1 to the internet, allowing you to remotely monitor ozone levels from anywhere. You can also receive instant notifications via text or email, ensuring that you stay informed of any safety concerns, no matter where you are.
Conclusion
The OA-1 Ozone Alarm is a robust, user-friendly device designed to ensure safety in environments where ozone exposure is a concern. With customizable alarms, external control capabilities, a real-time ozone level display, and a convenient field-replaceable sensor, the OA-1 offers long-term reliability with minimal maintenance. Add wireless monitoring and data logging to stay connected, and you have a comprehensive ozone detection solution that enhances safety and operational efficiency.
