FAQs

How long does the battery last?

The smoke alarm features a sealed 10-year battery that is designed to last the lifetime of the unit.

Can I replace the battery?

No, the battery is sealed and designed to last for 10 years. The entire unit should be replaced after 10 years or if it malfunctions.

How do I silence a nuisance alarm?

You can press the test/silence button on the unit. Alternatively, if you have purchased a compatible remote controller, you can use that to silence the alarm remotely.

What does the EN14604 certification mean?

This certification indicates that the smoke alarm has met stringent European safety standards for performance and reliability in detecting smoke.

Where should I install the smoke alarm?

Install smoke alarms on every level of your home and inside and outside sleeping areas. Avoid placing them directly in kitchens or bathrooms where steam or cooking fumes can cause false alarms, or near air vents.

Is this a smart smoke alarm?

Based on the product description, this is a standard, standalone smoke alarm and does not appear to have smart home connectivity features.

What is included in the box for installation?

The product typically includes an adhesive sticker and mounting brackets with screws for installation.

Troubleshooting

Alarm sounds intermittently (false alarms)

Ensure the alarm is not located near cooking appliances, bathrooms with steam, or heating/cooling vents. Clean the alarm of dust. If the issue persists, try relocating the alarm.

Alarm does not sound when the test button is pressed

Ensure the alarm is properly mounted. If it still does not sound, the unit may be faulty and requires replacement.

Low battery warning chirps (if applicable and differs from 10-year seal)

The 10-year sealed battery should not require replacement. If you hear chirping, it may indicate a malfunction, and the unit should be replaced.

Pros and Cons

Pros

  • 10-year sealed battery for long-term, hassle-free operation.
  • Convenient test/silence button for easy management of alarms.
  • Loud 85dB alarm ensures audibility.
  • Certified to European safety standards (EN14604).
  • Simple installation with included mounting hardware.

Cons

  • Remote silencing requires a separate purchase of a remote controller.
  • Battery is sealed and cannot be replaced before the 10-year lifespan.

Setup, Compatibility & Care

Setup:

  1. Choose a suitable location: typically on the ceiling or high on a wall, away from direct airflow from vents, fans, or windows.
  2. Mount the alarm: Use the included adhesive sticker for a temporary placement or the provided mounting brackets and screws for a permanent fixture.
  3. Test the alarm: Press the test button to ensure the alarm sounds correctly. The battery is pre-installed and activates upon initial setup.

Compatibility:

This smoke alarm is a standalone unit and does not require a Wi-Fi connection or smart home hub. The silencing feature can be optionally controlled by a compatible remote controller (sold separately).

Care:

  • Cleaning: Regularly dust the alarm cover with a soft cloth or the brush attachment of a vacuum cleaner. Never use water or cleaning agents, as this could damage the device.
  • Testing: Test the alarm monthly using the test button to ensure it is functioning correctly.
  • Battery: The battery is sealed for 10 years and cannot be replaced. The alarm should be replaced once the battery life expires or if the alarm malfunctions.
