Thank you for purchasing your ION Science product.
Standard warranty for the ARA is two years.
Hibernation models have a three-year warranty (if hibernation mode
is activated)
Hibernation models (ARA100H and ARA200H) require the ARA IR Link
p/n 908201 to activate and deactivate the Hibernation function.

Symbols
WARNING!
USED TO INDICATE DANGER WARNINGS WHERE THERE IS A RISK OF INJURY OR
DEATH.
Caution
Used to indicate a caution where there is a risk of damage to equipment.
Information
Important information or useful hints about usage.
Recycling

Ensure that waste electrical equipment is disposed of correctly.
Warnings, Cautions and Information notifications
The following Cautions apply to the product described in this manual.
If the ‘Activate Before Date’ marked on the package is expired, do not activate.
Do not attempt to replace the internal components. This could impair the intrinsic
safety rating and will void the warranty of the product.

Before daily use:
Make sure the sensor and audible port are clear of any obstruction such as debris
or blockages.
Perform the self-test to ensure the display, visual, audible and vibration alarms are
operating.
The sensor symbol stops blinking if the self-test is successful.
Ensure that the O2detector is zeroed at least every 30 days in a clear air
environment. See O2detector section for information on zeroing. The toxic gas
sensors (CO, H2S & SO2) may require calibration during the life of the product. ION
Science recommend bump testing frequently to ensure the sensor is functioning.
Perform a bump test at least every 30 days.
Please perform a bump test if the detector has been subject to physical impact,
liquid immersion, over limit alarm event, change of ownership or anytime the
detectors performance is in doubt.
Perform a bump test by exposing the detector to a concentration of gas that
exceeds the low alarm set points.
When selecting suitable bump test concentrations, please consider your local
health & safety exposure limits and ensure to take any necessary precautions when
handling these gases.
If the unit fails the bump test, attempt a calibration.
The accurate measurement of gas concentration depends upon the target gases
and the period.
The product is a gas detector, not a measuring device.
Do not attempt to replace the battery or sensor, the product is designed to be
maintenance free, changing these components will void the warranty.
If you suspect any malfunction or have any technical problems, please contact ION
Science.

The portable ARA has been designed and certified Intrinsically Safe.
Disposal
•The equipment does not include any toxic materials, but if it has been contaminated by toxic
materials, then exercise due care and follow the appropriate regulations when disposing.
•Always adhere to local regulations and procedures when disposing of the equipment.
•ION Science Ltd offers a take back service. Please contact us for more information.
RECYCLING
The detector contains a lithium battery that must be disposed in a recycling bin.
WEEE REGULATIONS
Ensure that electrical equipment is disposed of correctly.
The portable ARA has been designed and certified Intrinsically Safe.
Device Overview
The ARA is a portable, single gas detector. These devices are disposable and will operate for 2 years without
any replacement of components, to detect the presence of specific toxic gases or depleted/enriched Oxygen.
There are 4 single gas detector options:
1. Hydrogen Sulphide (H2S)
2. Carbon Monoxide (CO)
3. Sulphur Dioxide (SO2)
4. Oxygen (O2)
For ease of use, the ARA is single button operation. Ensure the manual is fully understood before using the
ARA.

Device overview
Diagram 1 below shows the key components of the product.
Activating ARA
To activate ARA within the validity period indicated on the packaging, press and hold down the button for
approximately 5 seconds.
On activation, ARA will sound an audible alarm, flash and vibrate in sequence.
A successful activation will display the life remaining (24 months) or the reading value.
Display (LCD and Symbols)
Ara uses an LCD display to show its status. In the absence of gas, it will display the life remaining. When gas is
present, the display will automatically shift to show what the gas concentration is.
NOTE: The display mode can be changed in the IR Link software with the "Life Remaining" and "Sensor
Reading" user options.
WARNING: If the display is missing icons or displayed figures can’t be read, please contact ION Science
promptly.

The table below shows the symbols and their meanings.
Self-Test
Prior to daily use, it is recommended that users perform a self-test to ensure ARA awareness alarms (audio,
visual and vibration) and all segments of the display screen are functioning correctly.

STEP 3
LOW and HIGH alarm set points will be displayed.
When LOW and HIGH alarm set points are displayed, the unit will perform STEP 2 if you press the button.
STEP 2
After pressing the button, the unit will perform the following sequence:
The right and left side LEDs light up after emitting audible beep and vibration.
All LCD display icons appear.
STEP 1
Sensor type icon will blink when a self-test is required. Press the button to perform the test.
STEP 4
When the self-test is successful, one short audible beep will sound, the unit will then turn to the original screen.
NOTES:
Self-test can be performed with the IR Link when the sensor icon isn’t blinking after 1 hour from self-test.
The self-test interval reminder can be defined by the user from 8 to 168 hours (7 days) via the IR Link software.
The factory default setting is 20 hours.
The unit will display the self-test reminder default setting is 20 hours. The period of self-test can be changed in
the IR-Link software from 8 hours to 7 days.
