WANLIN-303
Standalone photoelectric smoke alarm family
Review standalone, 433 MHz, LoRa or 4G candidates only after the exact hardware and radio version is identified.
Direct answer
What is an export standalone smoke alarm?
An export standalone smoke alarm detects smoke and provides a local audible warning without requiring a conventional fire alarm control panel. For IoT monitoring, buyers should first define the protected space, required local alarm behaviour, reporting method, power arrangement and destination-market evidence.
This page is written for IoT platform operators and retrofit monitoring integrators. It is a product-family selection resource, not a claim that every variant has the same approval, radio module or market access.

Important: “GB 20517-2006” is presented here as the execution standard stated by this manual. This wording is not a third-party certificate claim and does not establish destination-market acceptance. The manual also advises against use where relative humidity exceeds 95%, air speed exceeds 5 m/s, or heavy dust, water mist, steam, oil mist or corrosive gas is present.
Site-specific planning lens
How does Remote Fire Alarm Monitoring for Export Projects affect selection?
For this site's IoT monitoring focus, the planning lens is “Remote Fire Alarm Monitoring for Export Projects.” A useful specification begins with the protected space and maintenance plan, not with a radio acronym or a marketing family name.
The enquiry should state country, building use, quantity, sensing functions, communication preference, packaging language and target schedule.
A family-level brochure is useful for selection but is not proof that every radio, enclosure, battery or sensor configuration has identical market acceptance.
Existing site context: Explore Remote Fire Alarm Monitoring for Export Projects from Wanlin Fire, including system options, application guidance, compatibility information and support for distribution and projects. Use that context to define the application; it does not replace model-specific technical or compliance review.
The maintenance plan should identify battery or power checks, functional testing, device replacement, event escalation and ownership of any connected service.

Which product family fits the project?
WANLIN-307
Connected standalone smoke alarm family
Candidate configurations may include standalone, 433 MHz, LoRa, 4G or NB-IoT; availability and evidence must be confirmed per SKU/BOM.
WANLIN-309
Wireless reporting smoke alarm family
Use when the project requires a local alarm plus a defined reporting path; verify gateway, network and destination-market requirements.
WANLIN-370
Combination alarm reference
A smoke/heat/carbon-monoxide combination concept is not interchangeable with a smoke-only alarm; confirm the required sensing functions first.
What must buyers verify before ordering?
- Exact model and SKU/BOM
- Intended country and standard
- Certificate or report scope and validity
- Radio, gateway and network architecture
- Packaging, label and instruction language
Answers for buyers
Standalone smoke alarm questions
Which project details are needed for an accurate recommendation?
Provide the destination country, building type, quantity, required sensing functions, power preference, local-only or remote reporting need, radio or network constraints, packaging needs and target schedule.
Does remote notification replace the alarm sound?
No. Remote event reporting and local audible warning are separate functions. The project specification should define both and identify who responds to remote events.
What should be checked during sample approval?
Check model marking, sensing function, alarm behaviour, communication path, power arrangement, gateway or platform interaction, label artwork, manual revision and the evidence pack.
Who confirms destination-market acceptance?
The importer or another qualified party familiar with the destination requirements should confirm acceptance against current documents before an order is represented as market ready.
What is the difference between a certificate and a test report?
A certificate states a defined certification scope, while a test report records tests on identified samples or configurations. Neither should be extended to an unlisted model or variant.
Request a model-specific export review
Send the destination country, application, quantity, reporting method, preferred power arrangement and required delivery schedule to wanlinfirecontrol@163.com. Recommendations and formal claims remain subject to exact-model evidence review.
