Setup and Installation

Choosing a Location

Install smoke detectors in every sleeping area and on every level of your home, including the basement. For optimal protection, place detectors in hallways and large rooms. Avoid placing detectors near windows, doors, or air vents where drafts might interfere with smoke detection. Keep detectors at least 10 cm (4 inches) away from walls and corners when mounting on a ceiling.

Mounting the Detector

The X-Sense SD2J0AX can be installed using the provided screws or optional magnetic adhesive pads (sold separately).

1. Screw Installation:
   • Mark two drill holes on the ceiling or wall using the mounting bracket as a template.
   • Drill holes and insert the anchor plugs.
   • Attach the mounting bracket using the provided screws.
   • Align the detector with the mounting bracket and twist clockwise until it locks into place.
2. Magnetic Adhesive Pad Installation (Optional):
   • Ensure the mounting surface is clean, dry, and smooth.
   • Attach the magnetic adhesive pad (Ø70 mm, not included) to the back of the mounting bracket.
   • Press the bracket firmly onto the desired location on the ceiling or wall.
   • Align the detector with the mounting bracket and twist clockwise until it locks into place.

Operating Instructions

Initial Power-On

Once the detector is twisted onto the mounting bracket, it will automatically power on. The LED indicator will flash, and the unit will emit a short beep to confirm activation.

Testing the Detector

It is recommended to test your smoke detector weekly to ensure it is functioning correctly.

• Press and hold the Test/Silence button located on the front of the detector.
• The alarm will sound a loud, pulsating tone, and the LED indicator will flash rapidly.
• Release the button. The alarm should stop.
• If the alarm does not sound during the test, refer to the Troubleshooting section.

Silence Mode

If a nuisance alarm occurs (e.g., from cooking smoke), you can temporarily silence the alarm:

• Press the Test/Silence button once.
• The alarm will silence 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.
• Do not use the silence feature in a real fire emergency. Evacuate immediately.

Maintenance

Regular Cleaning

Dust and debris can accumulate on the smoke detector and affect its performance. Clean your detector at least once a month:

• Gently vacuum the exterior of the detector using a soft brush attachment.
• Wipe the surface with a clean, damp cloth. Do not use cleaning agents or solvents.
• Ensure the air vents are clear of obstructions.

Battery Life and Replacement

The X-Sense SD2J0AX is equipped with a sealed 10-year lithium battery. This battery is not replaceable by the user. When the battery is nearing the end of its life (approximately 10 years after activation), the detector will emit a low battery warning (a chirp every 60 seconds and a flashing LED). At this point, the entire unit must be replaced.
