Answers for buyers
Wireless sounder beacon questions
Which wireless versions are documented?
A separate manual documents the 433 MHz configuration, while the 4G manual and China regulatory records document an identified cellular configuration. LoRa appears in commissioned test records, but exact hardware, protocol and market evidence still require SKU/BOM confirmation.
Does WANLIN-656 detect smoke or heat by itself?
The supplied manual presents WANLIN-656 as a notification device linked with compatible initiating devices. It should not be described as a smoke or heat detector unless a separately documented configuration establishes that function.
What must an importer specify?
Specify the country, quantity, alarm workflow, sound and visual requirements, power arrangement, radio option, platform or gateway, label language and required evidence.
Do the China approvals prove CE, FCC, UL or global market approval?
No. The documented radio type approval and telecom network trial approval apply within their stated China scope. They do not establish CE, FCC, UL or destination-market acceptance.
What evidence should be reviewed before purchase?
Review the current controlled manual, exact SKU or BOM, radio documents, power details, compatibility record and destination-market requirements. Request model-matched evidence rather than relying on a family name.
