Frequently Asked Questions - WA100 FIRST ALERT
Why is my First Alert WA100 beeping every 30-60 seconds?
A chirp every 30-60 seconds usually indicates a low battery. Replace the 9V battery with a fresh one. If chirping continues, the detector may need cleaning or replacement.
How do I test my WA100 smoke detector?
Press and hold the test button for a few seconds. The alarm should sound loudly. If the alarm is weak or not sounding, replace the battery or clean the detector.
How often should I replace the battery?
Replace the 9V battery at least once a year or when the low battery chirp begins. For optimal safety, change batteries when daylight saving time ends.
How do I clean my WA100 detector?
Use a soft brush attachment on a vacuum cleaner to gently clean the vents. Do not use water or cleaning solutions. Clean every 6 months to reduce false alarms.
What is the lifespan of the WA100?
The detector should be replaced 10 years from the date of manufacture or when it reaches the end of its service life. Look for the date on the back.
How does the WA100 detect smoke?
It uses an ionization sensor that is sensitive to small smoke particles from fast-flaming fires. When smoke enters the chamber, it disrupts the current, triggering the alarm.
What should I do if my WA100 gives false alarms?
False alarms can be caused by steam, cooking smoke, or dust. Move the detector away from kitchens and bathrooms, or clean it. If problem persists, consider relocating the unit.
Where should I install the WA100?
Install on the ceiling or high on a wall (6-12 inches from ceiling) in hallways outside bedrooms. Avoid kitchens, bathrooms, and garages. Follow NFPA 72 guidelines.
Is the WA100 interconnectable with other detectors?
No, the WA100 is a standalone detector. It does not support interconnectivity with other units.
What is the warranty on the WA100?
First Alert offers a 5-year limited warranty for the WA100. Keep your proof of purchase and contact First Alert customer service for warranty claims.
