- Connect the wiring harness: Black to Black (Line), White to White (Neutral), and Orange to Orange (Interconnect). If your existing wiring uses different colors for interconnect, refer to the alarm's specific wiring diagram.
- Plug the wiring harness into the back of the SMICO100-AC alarm unit.

4. Operating Instructions
4.1 Initial Power-Up
Upon restoring power, the alarm will perform a self-test. A green LED indicator should illuminate, signifying normal operation. If the alarm chirps or sounds continuously, refer to the troubleshooting section.
4.2 Test/Silence Button
- Testing: Press and hold the Test/Silence button for a few seconds. The alarm will sound a loud, pulsating alarm pattern (3 beeps for smoke, 4 beeps for CO). This confirms the electronic circuitry, horn, and battery are working. Test weekly.
- Silencing Nuisance Alarms: In case of a non-emergency alarm (e.g., from cooking smoke), press the Test/Silence button to temporarily silence the alarm for several minutes. The alarm will automatically reset after the silence period if smoke or CO levels return to normal.
4.3 LED Indicators
- Green LED: Flashes once every 60 seconds, indicating the alarm is receiving AC power and operating correctly.
- Amber LED: Indicates a fault or malfunction. Refer to the troubleshooting section.
- Red LED: Flashes rapidly during an alarm event (smoke or CO detected).
5. Placement Guidelines
For optimal protection, install combination smoke and carbon monoxide alarms on every level of your home, including basements, and inside every bedroom. Additionally, place alarms in hallways outside sleeping areas.
6. Maintenance
6.1 Regular Testing
Test your alarm weekly by pressing the Test/Silence button. This ensures the unit is functioning correctly.
6.2 Battery Replacement
Replace the 9V battery at least once a year, or immediately when the alarm chirps every minute (indicating a low battery). To replace, open the battery drawer, remove the old battery, insert a new 9V alkaline battery, and close the drawer.
6.3 Cleaning
Clean your alarm monthly to remove dust and debris. Use a soft brush attachment on your vacuum cleaner to gently vacuum the alarm's vents. Do not use water, cleaners, or solvents.
6.4 Unit Replacement
Alarms have a limited lifespan. Replace your First Alert SMICO100-AC alarm at least every 10 years from the date of manufacture. The manufacture date is printed on the back of the alarm.
