Frequently Asked Questions - SMCO100V-AC FIRST ALERT
How do I install the First Alert SMCO100V-AC smoke detector?
Install by turning off power at the circuit breaker, then connect the alarm's quick-connector to the wiring harness, attach the mounting bracket to the ceiling or wall, and twist the alarm onto the bracket. Restore power and test.
How do I test the smoke detector?
Press and hold the Test/Silence button until the alarm sounds (a loud 85 dB beep). Release the button. If the alarm does not sound, check the battery and power connection.
What does a chirping sound from the detector mean?

Press the Test/Silence button to temporarily silence the alarm. The detector will automatically reset after a few minutes. Ensure the source of smoke or steam is removed.
How often should I clean the smoke detector?
Clean the detector monthly by vacuuming the vents with a soft brush attachment to remove dust and debris. Do not use water or cleaning solvents.
When should I replace the battery?
Replace the 9V battery annually or immediately when the low-battery chirp begins. Use a high-quality alkaline battery.

The detector has a 10-year lifespan from the manufacture date. Replace the entire unit after 10 years even if it appears to work.

Install on the ceiling or high on a wall at least 4 inches from a corner. Avoid kitchens, bathrooms, and garages to prevent false alarms.
