3.2 Installation Steps

1. Choose a suitable mounting location on the ceiling or wall, away from corners and obstructions.
2. Use the mounting bracket as a template to mark the drill holes.
3. Drill holes and insert the anchor plugs (if necessary).
4. Secure the mounting bracket to the ceiling/wall using the provided screws.
5. Attach the smoke alarm to the mounting bracket by aligning the alarm with the bracket and twisting clockwise until it clicks into place. The alarm will automatically activate upon proper mounting.

4. Operating the Alarm

4.1 Powering On

The smoke alarm is powered by a sealed 10-year lithium battery. It automatically activates once properly mounted onto the mounting bracket. No manual power-on is required.

4.2 Alarm Test & Silence Button

The large button on the front of the alarm serves as both a test button and a silence button.

• To Test: Press and hold the button for approximately 3 seconds. The alarm will sound loudly (85 dB) and the LED indicator will flash rapidly, confirming proper operation. Test the alarm weekly.
• To Silence: If the alarm triggers due to non-emergency smoke (e.g., cooking fumes), press the button once. The alarm will temporarily silence for up to 9 minutes. The LED indicator will flash every 5 seconds during the silence period. After 9 minutes, the alarm will reset to normal mode.

5. Maintenance

5.2 Cleaning

Clean the alarm cover and vents once a month to prevent dust buildup, which can affect detection sensitivity. Use a soft, damp cloth for the exterior and a vacuum cleaner with a soft brush attachment for the vents.

5.3 Battery Life

The sealed lithium battery provides 10 years of continuous power. The battery is not replaceable. When the 10-year lifespan is reached, the entire unit should be replaced.

6. Troubleshooting

If your smoke alarm is not functioning as expected, refer to the following common issues:

• False Alarms: Ensure the alarm is not installed in areas with high humidity, excessive dust, or near cooking fumes. Use the silence button if triggered by non-emergency smoke.
• No Alarm During Test: Ensure the alarm is properly mounted. If it still fails to alarm, the unit may be faulty and needs replacement.
• Low Battery/Malfunction Beeps: The alarm will indicate low battery or malfunction with specific beeps and LED flashes. Refer to the user manual for exact patterns. If the issue persists, replace the unit.
