- Do not block the alarm horn. Ensure nothing obstructs the sound output.
- Test the detector regularly, at least once a week, using the test button.
- Replace batteries as recommended to ensure continuous operation.
- Never ignore a carbon monoxide alarm. Immediately evacuate the premises and call emergency services.

4. Setup and Installation
4.1 Choosing a Location
For optimal performance and safety, install the detector in the following locations:
- Within 1 to 3 meters (3 to 10 feet) horizontally from the edge of fuel-burning appliances.
- In rooms with fuel-burning appliances (e.g., boiler rooms, kitchens with gas stoves, living rooms with fireplaces).
- In bedrooms or sleeping areas to alert occupants during sleep.
- At eye level or higher, but not directly above heat sources or in direct sunlight.
Avoid installing the detector:
- In dusty, dirty, or greasy areas.
- In areas with high humidity (e.g., bathrooms).
- Near vents, doors, or windows where drafts could affect readings.
- In areas where the temperature can drop below 0°C (32°F) or exceed 45°C (113°F).
4.2 Mounting the Detector
Follow these steps to mount your carbon monoxide detector:
- Select a suitable mounting location according to the guidelines above.
- Using the detector's mounting plate as a template, mark the positions for the two mounting holes on the wall.
- Drill two holes at the marked positions. Insert the provided wall plugs into the drilled holes.
- Insert the screws into the wall plugs, leaving a small gap (approx. 3mm) between the screw head and the wall.
- Align the keyhole slots on the back of the detector with the screw heads and slide the detector down to secure it.
- Ensure the detector is firmly attached to the wall.

5. Operating Instructions
5.1 Initial Power-On
After mounting, insert the required batteries (not included) into the battery compartment. The detector will perform a self-test, and the 'POWER' indicator light should illuminate, indicating it is operational.
5.2 Normal Operation
During normal operation, the 'POWER' indicator light will flash periodically (e.g., every 30-60 seconds) to confirm the unit is functioning correctly. If a fault is detected, the 'FAULT' indicator will illuminate.
5.3 Testing the Detector
It is crucial to test your carbon monoxide detector regularly to ensure it is working correctly. Follow these steps:
- Press and hold the 'TEST' button located on the front of the detector.
- The alarm will sound a loud, pulsating signal (85 dB) and the 'ALARM' indicator will flash.
- Release the 'TEST' button. The alarm should stop, and the detector will return to normal operation.
- If the alarm does not sound during the test, refer to the Troubleshooting section.
6. Maintenance
6.1 Regular Cleaning
To maintain optimal performance, clean your detector regularly:
- Gently vacuum the detector's vents and openings with a soft brush attachment to remove dust and debris.
- Wipe the exterior with a slightly damp cloth. Do not use cleaning sprays, solvents, or harsh chemicals.
- Do not paint the detector.
6.2 Battery Replacement
The detector is designed with a 1-year battery life. When the batteries are low, the 'FAULT' indicator may flash, or the unit may chirp periodically. Replace the batteries immediately with the recommended type (refer to specifications).
- Carefully remove the detector from its mounting plate.
- Open the battery compartment cover.
- Remove the old batteries and dispose of them properly.
- Insert new batteries, ensuring correct polarity (+/-).
- Close the battery compartment and re-mount the detector.
- Test the detector after battery replacement.
6.3 Sensor Life
The carbon monoxide sensor has a lifespan of 10 years. After 10 years, the detector should be replaced, even if it appears to be functioning correctly. The unit may indicate its end-of-life with a specific fault signal.
7. Troubleshooting
If your Smartwares PD-8826 Carbon Monoxide Detector is not functioning as expected, refer to the table below for common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm sounds unexpectedly (not a test) | High concentration of carbon monoxide detected. | Immediately evacuate all occupants. Call emergency services (fire department). Do not re-enter until the area has been declared safe. |
| Alarm sounds unexpectedly (not a test) | False alarm due to strong fumes (e.g., paint, cleaning products). | Ventilate the area. If the alarm persists after ventilation, treat it as a real CO alarm. |
| No alarm during test button press | Dead or low batteries. | Replace batteries with new ones. |
| No alarm during test button press | Faulty unit. | If new batteries do not resolve the issue, the unit may be faulty and needs replacement. |
| 'FAULT' indicator light is on or chirping | Low battery. | Replace batteries. |
| 'FAULT' indicator light is on or chirping | Sensor fault or end of life. | If battery replacement does not resolve the issue, the sensor may be faulty or has reached its end of life (10 years). Replace the detector. |
