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 OEM sourcing, buyers should first define the protected space, required local alarm behaviour, reporting method, power arrangement and destination-market evidence.
This page is written for importers, distributors and private-label procurement teams. 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 Wi-Fi Connected Fire Alarm Systems affect selection?
A retrofit project should record mounting constraints, existing network availability and whether the buyer expects a self-contained device or integration with a wider platform.
A family-level brochure is useful for selection but is not proof that every radio, enclosure, battery or sensor configuration has identical market acceptance.
Before approving a sample, compare the model marking, sensing function, communication module, power arrangement and document revision with the purchase specification.
For this site's OEM sourcing focus, the planning lens is “Wi-Fi Connected Fire Alarm Systems.” For export work, a product-family shortlist is only the start; the exact hardware, label, language and evidence pack must follow the selected configuration.
Existing site context: Wanlin Fire provides Wi-Fi Connected Fire Alarm Systems, with product selection guidance, technical specifications, OEM/ODM support and project supply for global buyers. Use that context to define the application; it does not replace model-specific technical or compliance review.

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
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.
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.
How should connected alarms behave during a network outage?
The project team should document local alarm behaviour, event buffering or retry expectations, supervision, user notification and the party responsible for restoring connectivity.
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 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.
