The Aroha Safety Pro Combimelder is designed for easy installation. Follow these steps for optimal placement and secure mounting.
4.1 Recommended Placement:
- Install at least one detector on each floor of your home, including the basement.
- Place detectors in or near sleeping areas.
- For smoke detection, mount on the ceiling in the center of the room, or at least 10 cm (4 inches) from any wall.
- For CO detection, place the detector at breathing height in rooms with fuel-burning appliances.
- Avoid placing near windows, doors, or ventilation openings that could interfere with detection.
- Avoid placing in 'dead air' spaces, such as the peak of a vaulted ceiling or in corners.
4.2 Mounting Instructions:
- Choose a suitable location according to the recommendations above.
- Use the mounting bracket as a template to mark two drill holes on the ceiling or wall.

5. Operation
Once installed, the Aroha Safety Pro Combimelder operates continuously, monitoring for smoke and carbon monoxide.
5.1 Normal Operation:
During normal operation, the LED indicator will flash briefly every 55 seconds, indicating that the unit is functioning correctly.
5.2 Smoke Alarm:
If smoke is detected, the alarm will sound with a loud, intermittent siren (three long beeps, pause, three long beeps) and the red LED will flash rapidly. This indicates a potential fire hazard.

5.3 Carbon Monoxide (CO) Alarm:
If dangerous levels of carbon monoxide are detected, the alarm will sound with a loud, intermittent siren (four short beeps, pause, four short beeps) and the red LED will flash rapidly. This indicates a potential CO poisoning hazard.
The detector provides early warnings for various CO concentrations:
- 300 ppm: Alarm within 3 minutes.
- 100 ppm: Alarm within 40 minutes.
- 50 ppm: Alarm within 90 minutes.

5.4 Silencing the Alarm:
To silence a nuisance alarm (e.g., from cooking smoke), press the large test/mute button on the front of the detector. The alarm will temporarily silence for approximately 10 minutes. If the smoke or CO concentration remains high, the alarm will reactivate after the mute period. Do not silence an alarm unless you are certain it is a false alarm.

6. Testing
It is crucial to test your Aroha Safety Pro Combimelder regularly to ensure it is functioning correctly. Test the detector weekly or at least once a month.
6.1 Performing a Test:
- Press and hold the large test/mute button on the front of the detector for at least 3 seconds.
- The alarm will sound with a series of beeps (smoke and CO alarm patterns) and the red LED will flash.
- Release the button. The alarm should stop.
- If the alarm does not sound or the LED does not flash during the test, refer to the 'Troubleshooting' section.
7. Maintenance
Minimal maintenance is required for the Aroha Safety Pro Combimelder due to its 10-year sealed battery and intelligent self-test function.
7.1 Cleaning:
- Dust and debris can accumulate on the detector and affect its performance.
- Gently vacuum the exterior of the detector using a soft brush attachment at least once a month.
- Do not use cleaning solvents or detergents on the detector.
7.2 End of Life Indication:
After approximately 10 years of operation, the detector will emit a short beep every 40 seconds, indicating that it has reached the end of its service life and needs to be replaced. The battery cannot be replaced.
8. Troubleshooting
If your Aroha Safety Pro Combimelder is not functioning as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not activate after installation. | Not properly twisted onto the mounting bracket. | Ensure the detector is fully twisted clockwise onto the mounting bracket until it clicks. |
| Alarm sounds intermittently (e.g., every 40 seconds). | End of service life. | Replace the detector immediately. |
| Alarm sounds during normal operation (not a test). | Presence of smoke or CO. | Evacuate immediately and call emergency services. If it's a nuisance alarm (e.g., cooking), press the mute button. |
| Test button does not trigger alarm. | Unit malfunction or end of life. | Ensure the button is pressed firmly for at least 3 seconds. If still unresponsive, replace the detector. |
| False alarms. | Dust, steam, cooking fumes, or improper placement. | Clean the detector. Relocate if frequently exposed to steam or fumes. Ensure proper ventilation during cooking. |
