Dual Sensor Smoke and Carbon Monoxide Detector with Photoelectric and Electrochemical Sensors

A combined detector should do more than put smoke and carbon monoxide functions into the same housing.

Smoke and carbon monoxide are fundamentally different hazards, so they require different sensing technologies.

The JKD-513COM Dual Sensor Smoke and Carbon Monoxide Detector combines:

Photoelectric Reflection Technology for Smoke

and

Electrochemical Sensing Technology for Carbon Monoxide

in one residential safety device.

This dual-sensor architecture is the central reason to choose JKD-513COM.

Instead of installing separate smoke detectors and carbon monoxide detectors for the functions provided by this unit, homeowners can use one compact device equipped with dedicated sensing technology for each hazard.

For distributors, importers and private-label brands, this creates a straightforward selling proposition:

Two hazards. Two dedicated sensors. One detector.

JKD-513COM uses a photoelectric reflection sensor for smoke monitoring.

The specified smoke alarm sensitivity is:

0.25dB/m

The detector also provides an approximately:

10-minute smoke alarm silence function

This allows temporary silencing according to the product's operating instructions.

For buyers sourcing a photoelectric smoke detector, sensor technology is an important specification because it clearly identifies how the smoke detection function operates.

JKD-513COM combines this dedicated smoke sensing system with independent CO detection rather than treating the two hazards as a single sensing function.

Carbon monoxide is invisible and cannot be detected by human senses.

JKD-513COM therefore incorporates a dedicated electrochemical CO sensor for carbon monoxide monitoring.

Its CO alarm response conforms to EN50291-1:2018:

The defined response at different concentrations gives distributors measurable technical information when evaluating a CO detector or carbon monoxide sensor.

The two sensing functions are supported by their respective product standards.

EN14604:2005/AC:2008

EN50291-1:2018

This is especially important for European distributors.

A generic "2 in 1 detector" claim does not explain the technical basis of the two detection functions.

JKD-513COM provides a much clearer proposition:

Photoelectric Smoke Detection according to EN14604

plus

Electrochemical CO Detection according to EN50291

inside one device.

JKD-513COM has a specified product life of:

10 years after manufacture

and is supported by SGS certification.

This makes it suitable for distributors seeking a long-life combined smoke and CO detector with recognized technical documentation.

Additional compliance includes:

• RoHS
• EMC
• UKCA

For OEM customers and private-label brands, the certification package provides an important foundation for product evaluation and market planning.

JKD-513COM is powered by:

3 x 1.5V AA alkaline batteries

The replaceable battery architecture provides a familiar power solution for residential users.

This also differentiates JKD-513COM from JKD-515COM, which uses a sealed long-life lithium battery.

JKD-513COM is therefore suitable for customers who want a 10-year CO smoke detector while retaining a replaceable battery design.

The specified average standby current is:

Less than 50μA

The average alarm current is:

Less than 70mA

Low standby current is particularly relevant for a battery-operated home safety detector, because the unit spends most of its operating time continuously monitoring the surrounding environment.

JKD-513COM is a:

Type B apparatus providing visual and audible alarm only

The specified audible alarm level is:

At least 85dB at 3 meters

The combination of sound and visual indication provides clear warning when an applicable alarm condition is detected.

The specified detection range is:

Maximum 40m² within a room

Installation options include:

• Ceiling installation
• Wall installation

The compact housing measures approximately:

Φ105 x 39mm

with a net weight of:

180 plus or minus 10g

This allows two detection technologies to be integrated into one compact residential unit.

A distributor can traditionally offer a standalone smoke alarm and a standalone CO alarm.

However, some consumers prefer one product that combines both functions.

JKD-513COM creates that additional product category.

It can complement rather than replace standalone detectors, giving retailers more options for different customer requirements.

The product is particularly suitable for:

• Fire safety distributors
• Home safety brands
• Electrical wholesalers
• Home improvement retailers
• DIY chains
• Property safety suppliers
• Importers
• OEM customers
• Private-label brands

For these buyers, the main value is not simply "2 in 1."

It is two dedicated sensing technologies supported by two corresponding standards.

JKD-513COM can support OEM, ODM and private-label projects.

Customization options can include:

• Customer logo
• Product labels
• Retail packaging
• Multilingual user manuals
• Barcode labels
• Master cartons
• Private-label branding

This makes the detector suitable for distributors looking to build their own smoke and carbon monoxide alarm range.

JKD-513COM is supported by:

SGS Certification

EN14604:2005/AC:2008

For the smoke detection function.

EN50291-1:2018

For the carbon monoxide detection function.

RoHS

EMC

UKCA

Available technical documentation can also include product specifications, technical datasheets, user manuals and applicable certification documents.
