4. Operation (Testing & Silencing)

Regular testing ensures your smoke alarm is always ready to protect your home.

• Monthly Test: Press and hold the large central Test/Silence button until the alarm sounds. The alarm will emit a loud, piercing sound. Release the button once the sound begins. This confirms the battery and alarm circuitry are working.
• Silencing Nuisance Alarms: In case of a false alarm (e.g., from cooking fumes), press the Test/Silence button once to temporarily silence the alarm for approximately 10 minutes. The alarm will automatically reset after this period. If the smoke persists, the alarm will reactivate.
• Sleep Easy Function: If the alarm chirps intermittently due to a low battery warning during the night, press the Test/Silence button to mute the low battery alert for 8 hours. This allows you to address the issue during daylight hours.

• Smoke detectors should be sited at least 300 mm (12 inches) from light fittings and walls.
• Install at least one smoke alarm on every level of your home, including hallways and landings.
• For optimal protection, consider installing alarms in living rooms and bedrooms.
• Not suitable for kitchens and bathrooms: The FA6620-R is an optical smoke alarm and is not recommended for installation in kitchens or bathrooms due to potential nuisance alarms from cooking fumes or steam.

6. Maintenance

Regular maintenance ensures the longevity and reliability of your smoke alarm.

• Monthly Test: Press the Test/Silence button monthly to ensure the alarm is functioning.
• Vacuum Every 3 Months: Gently vacuum the alarm's vents every three months to remove dust and debris that could obstruct the sensor.
• DO NOT use cleaners or solvents: Never use cleaning agents, solvents, or harsh chemicals on the device. Wipe with a slightly damp cloth if necessary.
• DO NOT paint the alarm: Painting the alarm can block the sensor openings and prevent it from detecting smoke.
• Cover during DIY: Cover the alarm when performing dusty DIY tasks nearby, such as sanding or drilling, to prevent dust ingress. Remember to uncover it immediately after.
