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 does standalone detection mean?
An export standalone smoke alarm detects smoke and provides a local audible warning without requiring a conventional fire alarm control panel. For fire safety projects, buyers should first define the protected space, required local alarm behaviour, reporting method, power arrangement and destination-market evidence.
This page is written for distributors, system integrators and project procurement teams. It is a product-family selection resource, not a claim that every variant has the same approval, radio module or market access.

Review the exact configuration, not only the family name
The image identifies a WANLIN-307 family reference. Radio, power, label and evidence scope can differ by controlled configuration; confirm the SKU/BOM before using any formal product or compliance statement.

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 Tibet Wireless Fire Alarm Systems affect selection?
Existing site context: Explore Tibet Wireless Fire Alarm Systems 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.
Destination-country acceptance should be reviewed by the importer or another qualified local party before labels, packaging and order documents are approved.
A procurement team should request a configuration-controlled quotation rather than a family name without its hardware and communication details.
For this site's fire safety projects focus, the planning lens is “Tibet Wireless Fire Alarm Systems.” Treat the alarm, communication path and destination-market evidence as three separate purchasing decisions.
Remote notification does not replace the local audible warning. Define both functions and the party responsible for receiving and acting on remote events.

How do the Wanlin model families differ?
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.
Answers for buyers
Standalone smoke alarm questions
Does a standalone smoke alarm require a fire alarm control panel?
A basic standalone alarm provides local detection and sound without a conventional panel. Connected variants may use a gateway, cloud platform or communication module, depending on the selected architecture.
Should importers approve the label before production?
Yes. Review the exact model, legal manufacturer or certificate holder where applicable, ratings, warnings, destination language and document references before production artwork is released.
Why is the exact SKU or BOM important?
Communication modules, power arrangements, labels and other components may differ within a family. Evidence and purchasing documents should therefore identify the exact controlled configuration.
Are product-family brochures sufficient for procurement approval?
No. Brochures support initial selection, but formal approval should use model-specific specifications, configuration records, applicable evidence, label artwork and current instructions.
What should be included in an OEM smoke alarm enquiry?
Include the destination market, application, quantity, sensing function, radio or network path, power preference, packaging language, branding scope and required evidence.
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.
