Cautions, Warnings and Hazards for working with ozone.
Refer to the manual of the ozone generating system first, to assure proper location of all
ozone equipment.
Ozone is a powerful oxidizing agent. Observe strict operating procedures when using
ozone equipment.
Ensure that the ozone system is in a well-ventilated area. he OA-1 Ozone Alarm must
be used indoors mounted 5-6 ft. from the floor.
Note: If the operator has asthma, he/she must not enter an ozonated airspace.
Ozone can induce an asthma attack.
Carefully review and familiarize yourself with the following important safety information
statements concerning the use of ozone.
WARNING Ozone is an extremely aggressive and powerful oxidizer. he
Occupational Safety and Health Administration (OSHA) 8-
hour exposure limit is 0.10-PPM. he OSHA 15-minute
exposure limit for ozone is 0.3 PPM. Above 0.3 PPM, there is
the risk of damage to respiratory tissues.
WARNING People who have no sense of smell should not operate this
equipment.
WARNING Never attempt to verify ozone production by directly breathing
or smelling the ozone outlet or an ozone-tubing outlet.
WARNING Make sure all tubing connections between the ozone
generator and the injection point are secure and in good
working condition. Failure to do so could result in the
discharge of undesired ozone into an occupied space.

Introduction
The OA-1 ozone alarm is a xed mount device with an audible alarm and visual strobe
light designed specically 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
- Auxiliary 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)

Installation
Mount the OA-1 Ozone Alarm in a clean, dust free environment that is non condensing.
Recommended mounting height is 5-6 ft.
Ambient Temperature should be between 50 and 86 deg. F.
Ambient Humidity should be in the range of 25 to 75% RH

Operation
- Plug OA-1 into 120 VAC outlet.
- The alarm will engage immediately upon powering it up - This is because the sensor
needs to warm up. Initial warm up may take from 30 minutes to 1 hour - 12 hours for
full warm up.
- After 30 minutes of warm up press the brown button on the circuit board inside to
perform a zero calibration make sure this is done in an ozone free environment.
- After 12 hours of warm up perform a zero calibration once more.
- Set ozone alarm set point – The dial in the upper right corner is 100% of sensor range.
Example - If sensor range is 1 ppm and the alarm is to be set at .1 ppm the dial will be
set to 1.
