Aroha Safety Pro CO Detector Manual

A. Activate/Deactivate the Detector

The device is deactivated by default before leaving the factory. Before use, it must be activated.

• Power On: Set the switch on the back of the detector to "ON" using the supplied stick. The detector beeps, and the LCD screen lights up blue, showing a value increasing from 000 to 999. Activation is complete when the screen displays 0 ppm.
• Power Off: Set the switch on the back of the detector to "OFF" using the supplied stick.

Why is the value 0 ppm? The default value is 0 ppm because the natural carbon monoxide (CO) in the air is approximately 0.2 ppm, which is rounded to 0 ppm. The display always shows the real-time CO level; in a "normal" situation, this is 0 ppm.

B. Test Your Alarm

Test the detector to ensure proper operation by pressing the test button. The alarm will sound if the detector is working correctly. If there is no sound, refer to the "Trouble shooting" section.

CAUTION:

• DO NOT test your detector using an open flame. This may damage the detector or ignite combustible materials, potentially starting a structural fire.
• DO NOT stand close to the detector when the alarm is sounding. Exposure at close range may be harmful to your ears.
• Test the detector at least once a month.

C. LED Indicators

• Normal status: Green LED flashes once every 60 seconds.
• Danger CO concentration: Red LED flashes 4 times and beeps 4 times every 5 seconds.
• Silence mode: Red LED flashes once every 8 seconds.
• Low battery status: Orange LED flashes 1 time and 1 beep every 60 seconds.
• Fault status: Orange LED flashes 2 times and 2 beeps every 40 seconds.
• End of life: Orange LED flashes 2 times and 2 beeps every 30 seconds.

D. Alarm

If an alarm signal sounds, immediately move to fresh air and do not re-enter the premises until they have been aired out and the alarm returns to its normal condition. Investigate the source of the CO release and repair the defect.

When does the alarm sound?

• 50 ppm: Alarm between 60 to 90 minutes
• 100 ppm: Alarm between 10 and 40 minutes
• 300 ppm: Alarm within 3 minutes

CAUTION: NEVER IGNORE ANY ALARM; carbon monoxide can be deadly.

E. Silence Mode

Silence mode should only be used if the source of the alarm is known and safe. Press the test button to set silence mode. During silence mode, the red LED light flashes once every 8 seconds. The detector automatically resets after 10 minutes.

CAUTION: Before using silence mode, identify the source and be certain a safe condition exists.

F. Mount the Detector

Determine correct mounting location: Detectors should be installed in a room with a combustion appliance (possible source of CO).

• At a horizontal distance between 1-3 meters from the CO source.
• OR, in rooms without a combustion appliance, place the detector at breathing height.
• Ensure a central location in the room, at least 30 centimeters from walls.
• Avoid existing air inlets or outlets and other objects on the ceiling.
• Avoid locations behind objects such as curtains and cupboards.

Mounting instructions: Use sticky pads or screws to mount the detector, or place the detector in the desired location without permanently mounting it.

G. Maintenance and Cleaning

Follow these steps to keep the detector working properly:

• Test the detector at least once a month.
• Do not paint the detector. Paint will seal the vents and interfere with the sensor's ability to detect CO.
• Never attempt to disassemble the detector to clean the inside. This will damage the detector and possibly render it unusable.
• Clean the detector at least once a month to remove dust, dirt, or debris. Use a vacuum cleaner with a soft brush and vacuum all sides and covers of the detector.
• Certain materials, vapors, or gases can affect alarm reliability in the short or long term. These include ethylene, ethanol, alcohol, isopropanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide, and sulfur dioxide. At high levels, these substances can damage the sensor or cause temporary readings that are not CO readings. Also, most aerosol sprays, alcohol-based products, paint, thinner, solvent, adhesive, hair spray, aftershave, perfume, and auto exhaust (cold start) can affect performance.

H. Trouble Shooting

• Detector does not sound when testing: Check if the detector is activated.
• Detector beeps every 60 seconds and red LED flashes: The battery is low; the detector needs to be replaced. Contact Aroha at contact@aroha.nl for replacement if the warranty is still in place.
• Detector beeps every 40 seconds and orange LED flashes: Clean the detector using a vacuum cleaner with a soft brush. If the issue persists, the detector is malfunctioning. Contact Aroha at contact@aroha.nl for replacement if the warranty is still in place.
• Detector beeps every 30 seconds and orange LED flashes: The detector is no longer working properly and needs to be replaced. Contact Aroha at contact@aroha.nl for replacement if the warranty is still in place.

I. Two Years of Warranty

During the specified warranty period of 2 years after purchase, Aroha will repair or replace any defective detector that is returned. This warranty does not apply if the detector has been damaged, modified, neglected, abused, or altered after the purchase date, or if it fails to operate due to improper maintenance. In such cases, the unit will not be replaced or repaired.

Please contact Aroha at contact@aroha.nl regarding the warranty.

The manufacturer shall have no liability for any personal injury, property damage, or any special, incidental, contingent, or consequential damage of any kind resulting from gas leakage, smoke, fire, or explosion.
