Description / OA-1 Ozone Alarm
The OA-1 ozone alarm is a fixed mount device with an audible alarm and visual strobe light designed specifically for use in human safety applications. This device features a user-settable alarm point with an auxiliary relay to control external devices such as fans, ozone generators, etc. The relay and alarm trigger together at the user-selected ozone set-point.
A large display is available to indicate both current ozone levels, and a trend of ozone levels over the last 12 hours of operation via a colorful graph.
Features:
- Red strobe light will alert of ozone levels above set-point
- Audible siren will alert of ozone levels above set-point
- Volume can be adjusted simply by turning the cover of the siren
- User-settable alarm set-point
- Auxillary relay (10-amp) can be used for external control, relay triggers simultaneously with the alarm set-point
- Optional display indicates current ozone level and trend of ozone levels over the last 12 hours Built-in fan will actively draw sample air past the ozone sensor
- Three separate ranges available
- 0-0.1 ppm
- 0-1.0 ppm
- 0-10.0 ppm
- - 4-20 mA output linear with ozone output
- Field Replaceable Sensor (never remove the unit from service for calibration)
Specifications:
- Range: three ranges available
- 0-0.1 ppm
- 0-1.0 ppm
- 0-10.0 ppm
- Resolution: Range dependent
- 0.1 ppm range = 0.01 ppm resolution
- 1.0 ppm range = 0.01 ppm resolution
- 10.0 ppm range = 0.1 ppm resolution
- Graphic Display: Indicates the current ozone level and past 12 hour trend graph
- Response time: Within 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. - 120 VAC to 12 VDC Adaptor included.
- Relay Outputs: 10 amp relay
- Analog output: 4-20 mA output linear with ozone level
- Calibration: Replace your sensor annually
Replaceable Sensor:
The OA-1 Ozone Alarm uses the SM-3 Sensor for ozone detection. This is a field-replaceable sensor chip that can be replaced every 6-months - 1-year to maintain ozone detection accuracy without ever having to remove the OA-1 from service. Simply pull the old sensor off, and replace it with new at a cost comparable to calibration.
As the replacement sensor has a similar cost to calibrating an existing sensor, long-term sensor + calibration cost will be lower than any other comparable sensor options that require calibration, then, eventual sensor replacement.
Data Logging:
Data logging with the OA-1 Ozone Alarm is possible with an external data logger such as the DL-3. Using the 4-20 mA output signal from the OA-1 the DL-3 can log and save gas measurements.
Wireless Monitoring & Data Logging Kit:
Use the Wireless Monitoring & Data logging Kit with your fixed mount monitor to connect it to the internet allowing access from anywhere. Receive Instant notifications with free text and email alerts. This is a great addition for your fixed mount gas detector.
