Answers for buyers
Wireless manual call point questions
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.
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.
Can one WANLIN-222 claim cover every radio configuration?
No. The model family alone does not prove identical radio modules, frequency bands, firmware, labels or market evidence across all variants.
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 must an importer specify?
Specify the country, quantity, activation and reset workflow, power arrangement, radio option, receiving panel or platform, label language, mounting method and required evidence.
