Photoelectric Smoke and Electrochemical Carbon Monoxide Alarm with 10 Year Product Life

Photoelectric Smoke and Electrochemical CO Alarm for Dual Hazard Monitoring

Two Different Hazards Need Two Different Sensing Technologies

A combination smoke and carbon monoxide alarm should not be evaluated simply by the number of functions printed on its packaging.

The more important question is:

How does the product detect each hazard?

Smoke and carbon monoxide are fundamentally different. Smoke consists of airborne particles generated by combustion, while carbon monoxide is an invisible and odorless gas.

The JKD-514COM smoke and carbon monoxide alarm therefore uses two dedicated sensing technologies:

Photoelectric reflection sensing for smoke

and

Electrochemical sensing for carbon monoxide

This dual-sensing architecture is the central purchasing reason for this JKD-514COM.

For distributors, importers and private-label brands, it provides a clear technical proposition: one residential alarm housing, two different hazards, and a dedicated sensor technology for each.

Photoelectric Smoke Sensing Technology

The smoke alarm function of JKD-514COM is based on:

Photoelectric Reflection Technology

with a specified smoke sensitivity of:

0.25dB/m

The photoelectric smoke sensor continuously monitors for conditions associated with smoke and provides the dedicated sensing system for the fire alarm function.

This allows JKD-514COM to address B2B buyers looking for a photoelectric smoke alarm for residential applications, while adding carbon monoxide monitoring within the same product.

The smoke function also includes an approximately:

10-minute alarm silence period.

This provides a practical feature for temporary silencing according to the operating instructions.

Electrochemical CO Sensor for Carbon Monoxide Monitoring

The second sensing system is designed specifically for carbon monoxide.

JKD-514COM incorporates an:

Electrochemical CO Sensor

Carbon monoxide cannot be seen or smelled, which means the sensing element plays a critical role in residential monitoring.

Rather than describing the product using vague terms such as sensitive or advanced, JKD-514COM provides defined CO alarm response specifications.

These values conform to EN50291-1:2018.

For buyers comparing an electrochemical carbon monoxide alarm, these measurable response levels provide much more useful information than general marketing claims.

Two Sensors Supported by Two Product Standards

The sensing architecture is also reflected in the certification structure.

For smoke monitoring:

EN14604:2005/AC:2008

For carbon monoxide monitoring:

EN50291-1:2018

This means the two core functions of the combination smoke and CO alarm are supported by their respective standards.

JKD-514COM is also supported by SGS certification, which is particularly relevant for European distributors performing supplier qualification and technical product evaluation.

Additional compliance includes:

RoHS

EMC

UKCA

Why Dual Sensing Is a Strong Retail Proposition

For consumers, the technical explanation can remain simple:

Smoke Sensor plus CO Sensor in One Alarm

For distributors, however, the technical structure provides additional value.

Instead of stocking only standalone products, a retailer can offer a 2 in 1 smoke and carbon monoxide alarm for customers who want both functions in one housing.

The product can complement:

• Standalone smoke alarms
• Standalone carbon monoxide alarms
• Long-life home safety alarms
• Residential fire safety products

This gives retailers another product tier without requiring an entirely different safety category.

10 Year Product Life

JKD-514COM has a specified:

10 Year Product Life After Manufacture

This gives the dual-sensing platform a long-term residential positioning.

Rather than offering smoke and CO functionality in a short-life entry-level product, JKD-514COM combines its two sensing technologies with a defined 10-year product lifecycle.

For distributors, this provides another useful long-tail proposition:

10 year photoelectric smoke and electrochemical CO alarm for home use

The product is powered by replaceable AA alkaline batteries, providing a familiar battery architecture for residential users.

Low Standby Current for Continuous Monitoring

A smoke and CO alarm spends most of its operating time continuously monitoring the environment.

JKD-514COM has a specified average standby current of:

Less Than 50μA

with an average alarm current of:

Less Than 70mA

These specifications provide technical buyers with measurable electrical information when evaluating a battery operated smoke and CO alarm for long-term residential use.

Visual and Audible Alarm

JKD-514COM is classified as:

Type B to provide a visual and audible alarm only

When an applicable alarm condition occurs, the unit provides visual indication together with an audible warning.

The specified alarm sound pressure is:

At Least 85dB at 3 Meters

This provides a clear warning for occupants while keeping the overall product architecture straightforward for residential use.

Maximum 40m2 Room Coverage

The specified detection range is:

Maximum 40m2 Within a Room

JKD-514COM supports:

Ceiling Installation

or:

Wall Installation

according to the product instructions and applicable installation requirements.

The housing measures approximately:

Φ105 x 39mm

making it possible to integrate both smoke and carbon monoxide sensing into one compact residential alarm.

Suitable for Residential Safety Product Ranges

JKD-514COM is suitable for:

• Houses
• Apartments
• Residential buildings
• Rental properties
• Holiday homes
• Home improvement retail
• Electrical distribution
• Fire safety distribution

For OEM customers, the product also provides a useful platform for building a private label smoke and carbon monoxide alarm range.

Customization can include logos, product labels, retail packaging, multilingual manuals, barcodes and master cartons.
