85dB Smoke and Carbon Monoxide Alarm with Visual and Audible Warning

The purpose of a home safety alarm is not simply to sense a hazard.

Once smoke or carbon monoxide reaches an applicable alarm condition, the product must communicate that danger clearly to people inside the home.

This is the core focus of the JKD-514COM smoke and carbon monoxide alarm.

The product combines visual indication with a specified audible alarm level of:

JKD-514COM is classified as a Type B apparatus designed to provide visual and audible alarm only.

For distributors and residential safety brands, this creates a clear purchasing proposition: one combined alarm monitors both smoke and carbon monoxide and provides a strong audible warning together with visual indication when an applicable alarm condition occurs.

The specified alarm sound pressure of JKD-514COM is:

≥85dB at 3m

This is an important technical parameter for a residential smoke and CO alarm, because sensing a hazard is only one part of the safety function.

The alarm must also alert occupants.

Rather than describing the product with vague phrases such as "loud alarm," JKD-514COM provides a measurable sound-pressure specification.

For B2B buyers comparing residential safety products, this provides a concrete parameter that can be included in catalogs, technical datasheets and retail product descriptions.

JKD-514COM provides:

Audible Alarm

and

Visual Indication

within the same product.

This dual warning method gives occupants more than one form of alarm indication.

The product is designed as a combined smoke and carbon monoxide alarm, so the same compact housing integrates sensing electronics, alarm sound output, visual indicators and two dedicated sensor technologies.

For retailers, the message is easy to communicate:

Smoke and CO monitoring with sound and light warning in one residential alarm.

Smoke monitoring is performed by a:

Photoelectric Reflection Sensor

with a specified smoke alarm sensitivity of:

0.25dB/m

The smoke alarm function follows:

EN14604:2005/AC:2008

JKD-514COM also includes an approximately:

10-minute smoke alarm silence function.

This combination allows the model to be positioned as a photoelectric smoke alarm with audible and visual warning, while simultaneously providing carbon monoxide monitoring.

Carbon monoxide requires a different sensing technology.

JKD-514COM therefore incorporates a dedicated:

Electrochemical CO Sensor

The carbon monoxide alarm function conforms to:

EN50291-1:2018

with specified response characteristics:

These defined response levels provide professional buyers with measurable technical information when evaluating a home carbon monoxide alarm or electrochemical CO sensor.

Installing separate products for different hazards is common, but combined products can provide another option for suitable residential applications.

JKD-514COM integrates:

Smoke Sensor

plus

CO Sensor

plus

Audible Warning

plus

Visual Warning

inside one compact housing.

This makes it a useful combination smoke and CO alarm for home use, particularly for retailers and distributors that want to offer both standalone and combined safety products.

JKD-514COM has a specified:

10 Year Product Life After Manufacture

This gives the model a long-term residential product position rather than an entry-level short-life profile.

The alarm uses replaceable AA alkaline batteries, providing a familiar power architecture for household users.

The average standby current is:

Less than 50μA

and the average alarm current is:

Less than 70mA.

These electrical specifications support continuous battery-powered monitoring during everyday operation.

The two sensing functions are supported by two corresponding European product standards.

For smoke:

EN14604:2005/AC:2008

For carbon monoxide:

EN50291-1:2018

JKD-514COM is also supported by:

SGS Certification

RoHS

EMC

UKCA

This documentation package is relevant for importers, wholesalers, retailers and private-label brands evaluating a certified smoke and carbon monoxide alarm for the European market.

The specified detection range is:

Maximum 40m² Within a Room

JKD-514COM supports:

Ceiling Installation

or:

Wall Installation

according to the supplied instructions and applicable requirements.

Operating conditions are specified between:

-10°C and +50°C

with:

Less than 95 percent RH non-condensing.

These characteristics make the alarm suitable for appropriate residential applications in houses, apartments, rental properties and other home environments.

The approximate dimensions are:

Φ105 x 39mm

with a net weight of approximately:

180 plus or minus 10g.

Within this compact housing, JKD-514COM combines:

• Photoelectric smoke sensing
• Electrochemical CO sensing
• Audible warning
• Visual indication
• Battery-powered electronics

For distributors, this creates a practical combined safety SKU without requiring separate housings for the two sensing functions provided by the product.

Many product descriptions focus heavily on sensor type and certification.

However, warning output should also be part of the purchasing evaluation.

JKD-514COM provides a measurable specification:

At Least 85dB at 3 Meters

combined with visual indication.

For B2B buyers, this means the product can be compared using concrete technical data rather than unsupported claims such as "extra loud" or "powerful."

The complete selling proposition becomes:

Photoelectric smoke sensing

Electrochemical CO sensing

Visual alarm indication

At least 85dB audible warning

10-year product life

EN14604 and EN50291

This gives distributors several concrete features to communicate to customers.

JKD-514COM supports OEM, ODM and private-label cooperation for:

• Home safety brands
• Fire safety distributors
• Electrical wholesalers
• DIY retailers
• Residential safety suppliers
• Importers

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

JKD-514COM is supported by:

SGS Certification

EN14604:2005/AC:2008 Smoke Alarm Standard

EN50291-1:2018 Carbon Monoxide Alarm Standard

RoHS

EMC

UKCA

Technical datasheets, specifications, user manuals and applicable certification documents can be provided for B2B product evaluation.
