Answers for buyers
Wireless manual call point questions
Does WANLIN-222 detect smoke or heat by itself?
No. The supplied documents present WANLIN-222 as a manual alarm call point. A person initiates the event by operating the button.
Which wireless versions are documented?
A separate manual documents the 433 MHz configuration. Commissioned reports record 4G, LoRa and NB-IoT network modes, while China regulatory records identify a TD-LTE/LTE FDD configuration. Exact hardware and evidence require SKU/BOM confirmation.
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.
How should the alarm path be commissioned?
Test button activation, event transmission, receiving-panel or platform receipt, reset operation, low-battery indication, network outage behaviour and final notification routing.
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.
