The JKD-518 is a sealed battery smoke detector designed to provide dependable residential fire protection with minimal maintenance. Featuring a built-in 10-year lithium battery, it eliminates the need for routine battery replacement during the detector's intended service life.

The detector uses a photoelectric sensing chamber to continuously monitor for smoke. When smoke reaches the specified alarm threshold, it activates an audible alarm of at least 85dB, helping occupants respond promptly to a potential fire emergency.

Manufactured according to EN14604:2005/AC:2008, the JKD-518 is also available in configurations for markets requiring AS3786:2023, making it suitable for international distributors and private-label brands.

Sealed battery smoke detectors have become increasingly popular in residential fire safety because they simplify maintenance and reduce the likelihood of battery removal.

Compared with replaceable-battery models, a sealed battery design offers several practical benefits:

• No routine battery replacement during normal service life
• Reduced maintenance requirements
• Lower risk of missing protection due to removed batteries
• Cleaner product design with no battery compartment access
• Suitable for long-term residential installations

These advantages make sealed battery models an attractive option for housing developers, landlords and property management companies.

The integrated lithium battery is designed to power the detector throughout its intended service life, helping reduce ongoing maintenance requirements.

The detector uses a photoelectric reflection sensor that responds to visible smoke particles commonly generated during residential fires.

When smoke is detected, the alarm produces a sound level of ≥85dB, providing a clear warning for building occupants.

The integrated Test/Silence button allows users to verify detector operation and temporarily silence nuisance alarms for approximately 10 minutes after confirming there is no fire.

The detector is designed for ceiling or wall installation and blends easily into modern residential environments.
