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 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.

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 Shaanxi Wireless Fire Alarm Systems affect selection?
For this site's fire safety projects focus, the planning lens is “Shaanxi Wireless 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: This resource explains Wanlin Fire shaanxi wireless fire alarm systems, key specifications, suitable applications and purchasing considerations for professional buyers. Use that context to define the application; it does not replace model-specific technical or compliance review.
Distributors should confirm private-label scope, artwork ownership, manual languages, sample approval and how production changes will be communicated.
Destination-country acceptance should be reviewed by the importer or another qualified local party before labels, packaging and order documents are approved.
433 MHz, LoRa, 4G and NB-IoT describe different communication paths; they are not interchangeable labels and may change the hardware, infrastructure and regulatory 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.
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.
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.
When should a combination alarm be selected?
Select a combination concept only when the project explicitly requires its sensing functions. A smoke, heat and carbon-monoxide combination device is not automatically interchangeable with a smoke-only alarm.
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.
