Product Description
Carbon Monoxide Alarm with Alarm Memory for Better Safety Awareness

Product Introduction

Carbon monoxide alarms are designed to warn occupants when dangerous gas levels are detected. However, alarm events do not always happen when people are at home. A detector may activate while the property is unoccupied or when residents are asleep and unable to determine exactly what occurred.

The JKD-616 addresses this challenge with an alarm memory function that records previous alarm events. Together with an electrochemical sensor and an LCD display, this feature gives users additional information after an alarm has occurred, helping them decide whether further inspection of fuel-burning appliances or ventilation systems is necessary.

For distributors and private-label brands, the alarm memory function adds practical value to a residential carbon monoxide alarm without increasing operational complexity.


Why Alarm Memory Is Useful

A standard carbon monoxide alarm warns users during an active alarm condition. Once the alarm stops, occupants may not know whether carbon monoxide was detected while they were away.

An alarm memory function helps solve this problem by indicating that an alarm event has previously occurred.

This allows users to:

  • Confirm whether the detector has entered an alarm condition
  • Check the property after returning home
  • Investigate boilers, fireplaces or other fuel-burning appliances
  • Decide whether professional maintenance is required

For homeowners, this provides additional confidence. For landlords and property managers, it offers a simple way to identify whether a detector has reported a previous event.


Key Features
Alarm Memory Function

The detector records previous alarm events, allowing users to check whether carbon monoxide has been detected since the last reset.

Electrochemical Sensor

A high-quality electrochemical sensor continuously monitors carbon monoxide concentration and provides reliable residential detection.

LCD Display

The LCD screen displays real-time carbon monoxide concentration, giving users continuous visibility of indoor CO levels.

Human Voice Prompt

In addition to audible and visual alarms, the JKD-616 supports customizable voice prompts, helping occupants quickly identify the type of alarm during an emergency.

Automatic Sensor Fault Detection

The detector continuously checks sensor status and provides a warning if a fault is detected.

Low Battery Warning

A low battery reminder helps ensure the detector remains operational by notifying users when battery replacement is required.


Designed for Everyday Residential Use

The JKD-616 is suitable for a wide range of residential applications, including:

  • Houses
  • Apartments
  • Holiday homes
  • Rental properties
  • Student accommodation
  • Residential care facilities

Its combination of alarm memory, LCD display and voice prompts makes it particularly suitable for users who want additional information beyond a standard warning signal.
