4. Setup and Installation
4.1 Package Contents
- SITERWELL Smoke and Carbon Monoxide Detector(s)
- Mounting Bracket
- Screws and Wall Plugs
- User Manual
4.2 Choosing a Location
Proper placement of your detector is crucial for effective protection. Follow these guidelines:
- Install at least one detector on every level of your home, including basements and attics.
- For smoke detection, place detectors inside each bedroom and in the hallway outside sleeping areas.
- For carbon monoxide detection, place detectors near sleeping areas and on every level of the home.
- Mount on a ceiling or high on a wall (at least 4 inches from the ceiling).
- Avoid placing detectors near windows, doors, or vents where drafts could interfere with detection.
- Keep detectors at least 20 feet away from combustion sources like furnaces, water heaters, and cooking appliances to minimize false alarms.
4.3 Mounting the Detector
- Select a suitable mounting location (ceiling or wall).
- Use the mounting bracket as a template to mark the screw holes on the ceiling or wall.
- Drill holes at the marked positions. Insert wall plugs if mounting into drywall or plaster.
- Secure the mounting bracket to the ceiling or wall using the provided screws.
- Align the detector with the mounting bracket and twist clockwise until it locks securely into place.
- Perform an initial test as described in Section 5.2.

5. Operating Instructions
5.1 Initial Power-On
The detector is equipped with a sealed 10-year battery. Once mounted, the device will automatically activate. A green LED will flash periodically, indicating normal operation.
5.2 Testing the Detector
It is recommended to test your detector weekly to ensure it is functioning correctly.
- Press and hold the 'TEST/MUTE' button located on the front of the detector.
- The detector will emit a series of loud beeps and voice alerts (e.g., "Fire!", "Warning, carbon monoxide").
- Release the button. The alarm should stop.
- If the alarm does not sound during the test, refer to the Troubleshooting section.

5.3 Wireless Interconnection
This detector can wirelessly interconnect with up to 18 compatible SITERWELL alarms. When one interconnected alarm detects smoke or carbon monoxide, all linked alarms will sound, providing comprehensive coverage throughout your home.
Refer to the specific interconnection instructions provided with your multi-pack or individual units for pairing procedures.

5.4 Dual Language Voice Alerts
The detector provides voice alerts in both English and French. The default language is typically English. To switch languages or confirm the current setting, refer to the specific instructions for your model, usually involving a sequence of presses on the 'TEST/MUTE' button during initial setup or a specific mode.

5.5 Do Not Disturb Mode
If the detector signals a low voltage or a fault, pressing the 'TEST/MUTE' button will activate a 'Do Not Disturb' mode for approximately ten hours. This temporarily silences nuisance alerts, particularly useful during nighttime, without compromising safety during an actual emergency.
6. Maintenance
6.1 Cleaning
Clean your detector at least once a month to remove dust and debris. Use a soft brush attachment on your vacuum cleaner to gently clean the exterior of the alarm. Do not use water, cleaning solutions, or solvents, as these can damage the unit.
6.2 Battery Life
The SITERWELL detector is equipped with a sealed 10-year lithium battery. This battery is designed to last the entire lifespan of the alarm under normal operating conditions. The battery is not replaceable by the user.

6.3 End of Life Indication
When the detector reaches the end of its 10-year lifespan, it will emit a specific end-of-life signal (e.g., a chirp every 30-40 seconds, accompanied by a voice alert). When this occurs, the entire unit must be replaced immediately. Do not attempt to disable or ignore this signal.
7. Troubleshooting
If your detector is not functioning as expected, consult the table below for common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm chirps periodically (e.g., every 30-40 seconds) | End of life indication or fault. | Replace the entire detector unit immediately. |
| Alarm sounds frequently without apparent smoke/CO | Nuisance alarm (steam, cooking fumes, dust) or detector placed too close to combustion sources. | Press the 'TEST/MUTE' button to silence. Relocate the detector if nuisance alarms persist. Clean the detector. |
| Detector fails to test | Unit malfunction or end of life. | Ensure the unit is properly mounted. If it still fails, replace the detector. |
| Interconnected alarms do not all sound | Interconnection issue or out of range. | Verify all units are properly paired. Check distance between units. Refer to interconnection instructions. |
