5. Interconnection (Wireless Linking)
The ANKA AJ-763SI4 smoke alarms are designed to interconnect wirelessly, meaning if one alarm detects smoke, all linked alarms will sound. This feature provides comprehensive coverage and early warning throughout your property.
- Power On: Ensure all alarms you wish to interconnect are powered on.
- Initiate Linking: On one alarm (the master), press and hold the test/interconnect button for approximately 3-5 seconds until the LED indicator flashes rapidly.
- Link Other Alarms: Within 60 seconds, press the test/interconnect button on each additional alarm you want to link. The LED on these alarms should also flash rapidly, then briefly illuminate steadily to confirm successful linking.
- Test Interconnection: After linking all units, press the test button on any one alarm. All interconnected alarms should sound simultaneously. If not, repeat the linking process.

6. Operating Instructions
Understanding the alarm's indicators and functions is essential for effective use.
- Normal Operation: The LED indicator will flash briefly every 40-60 seconds, indicating the alarm is functioning correctly.
- Alarm Condition: When smoke is detected, the alarm will emit a loud, pulsating siren, and the LED will flash rapidly. If interconnected, all linked alarms will also sound.
- Test Function: Press and hold the test button for a few seconds. The alarm will sound briefly, confirming its operational status. Perform this test weekly.
- Silence Function: In case of a nuisance alarm (e.g., from cooking fumes), press the test/silence button. This will temporarily silence the alarm for approximately 9 minutes. The alarm will automatically reset after this period if smoke levels have cleared. If smoke is still present, the alarm will reactivate.

7. Maintenance
Regular maintenance ensures the longevity and reliability of your smoke alarm.
- Battery: The ANKA AJ-763SI4 features a built-in 10-year battery. This battery is not replaceable. When the battery is low, the alarm will chirp periodically (typically once every 40-60 seconds) and the low battery indicator will flash. Replace the entire unit immediately when this occurs.
- Cleaning: Dust and debris can affect the alarm's performance. Clean the smoke alarm at least once a month by gently vacuuming the exterior casing and air vents using a soft brush attachment. Do not use water or cleaning solvents.
