5. Installation
5.1 Choosing a Location
For optimal protection, install smoke detectors in every sleeping area and on every level of your home, including the basement. Consider placing detectors in hallways leading to sleeping areas. Avoid placing detectors in:
- Kitchens, bathrooms, or garages where cooking fumes, steam, or exhaust can cause false alarms.
- Areas with high humidity or extreme temperatures.
- Near vents, fans, or air conditioners that can interfere with smoke reaching the detector.

5.2 Mounting Instructions
The X-Sense SD11 can be installed using screws or a magnetic mount (sold separately).
Screw Mounting:
- Choose a suitable mounting location on the ceiling or wall.
- Use the mounting bracket to mark the two screw holes.
- Drill two holes (approximately 6 mm in diameter) at the marked positions.
- Insert the anchor plugs into the holes.
- Attach the mounting bracket using the provided screws.
- Align the detector with the mounting bracket and twist clockwise until it locks into place.
Magnetic Mounting (Optional, magnetic pads sold separately):
- Ensure the mounting surface is clean, dry, and smooth.
- Attach the magnetic adhesive pads to the back of the detector and the desired mounting location.
- Press the detector firmly against the magnetic pad on the ceiling/wall for secure attachment.
5.3 Initial Activation
Once the detector is twisted onto the mounting bracket, it will automatically activate. The LED indicator will flash briefly, and the unit will emit a short beep to confirm activation.
6. Operating Instructions
6.1 Testing the Alarm
It is recommended to test your smoke detector weekly to ensure it is functioning correctly.
- Press and hold the Test/Silence button on the detector.
- The alarm will sound loudly (a series of three long beeps) and the LED indicator will flash rapidly.
- Release the button. The alarm will stop.

6.2 Silence Function
If a non-emergency alarm occurs (e.g., from cooking fumes), you can temporarily silence the alarm:
- Press the Test/Silence button once.
- The alarm will be silenced for approximately 9 minutes. The LED indicator will flash every 5 seconds to indicate it is in silence mode.
- After 9 minutes, if smoke is still present, the alarm will reactivate.
6.3 Automatic Self-Test
The X-Sense SD11 performs an automatic self-test every 10 seconds to ensure its internal components are functioning correctly. It also checks for smoke every 10 seconds for precise and intelligent detection.

7. Maintenance
7.1 Cleaning Your Smoke Detector
To keep your smoke detector in good working condition, clean it regularly (at least once every 6 months):
- Gently vacuum the exterior of the detector using a soft brush attachment to remove dust and debris.
- Do not use water, cleaning solutions, or solvents, as these can damage the unit.
7.2 Battery Life and End-of-Life Indication
The X-Sense SD11 is equipped with a sealed 10-year lithium battery. This battery is designed to power the detector for its entire lifespan, eliminating the need for battery replacement.
Image 7.1: The detector features a 10-year sealed lithium battery for long-term operation.
When the detector reaches the end of its 10-year lifespan, it will emit a specific end-of-life signal (typically a short beep every 30-40 seconds) to indicate that it needs to be replaced. Replace the entire unit promptly.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm sounds frequently without apparent smoke (false alarms). | Dust or debris in the sensing chamber; detector too close to cooking fumes, steam, or high humidity. | Clean the detector as described in Section 7.1. Relocate the detector if it is in an unsuitable area. The insect-proof design helps minimize insect-related false alarms. |
| Detector chirps or beeps intermittently (e.g., every 30-40 seconds). | Low battery or end-of-life signal. | The integrated 10-year battery is nearing its end of life. Replace the entire smoke detector unit immediately. |
| Alarm does not sound during testing. | Detector not properly activated; unit malfunction. | Ensure the detector is correctly twisted onto its mounting bracket. If the issue persists, the unit may be faulty and needs replacement. |
