Export wireless heat detection resource
Plan export wireless standalone heat detection for drying workshops and maintenance decisions, with WANLIN-340 evidence, network checks and radio-scope.
Direct answer
A standalone heat detector monitors temperature and provides a local audible and visual warning when its defined alarm condition is reached, without requiring a conventional fire alarm control panel. It should be selected where the fire strategy and normal environment support heat detection.
Heat detection does not replace smoke detection automatically. A qualified project review should decide the detector type and placement for each space.
Documented model
The supplied Ver 1.0 manual documents a WANLIN-340 temperature-sensing alarm and describes an NB-IoT reporting module. This does not prove that every WANLIN-340 SKU contains the same radio, platform or evidence scope.

Model-matched test evidence
Shenyang Fire Research Institute, Ministry of Emergency Management issued a type test report (not a product certification certificate) for model WANLIN-340. The report lists 14 samples and a test period of 2023-09-26 to 2023-12-04.
The stated basis is GB 30122-2013 and GB 12978-2003 inspection rules. The report concludes: All applicable GB 30122-2013 items tested in the report were judged compliant.
Two action-temperature results shown are 58.5 °C and 58.3 °C. Initial sound-pressure results for 14 samples range from 70.5 to 72.5 dB. These are report measurements, not guaranteed values for every production unit.
Evidence boundary: the report is dated 2023-12-07 and identifies a Class AS, point-type fixed-temperature alarm. It does not by itself prove that every radio or cloud variant has identical construction, nor does it constitute destination-market approval.
Marketing-material reconciliation: a supplied promotional image states an alarm-action upper limit of 65 °C. That is kept separate from the report's measured sample results of 58.3-58.5 °C and from the manual's operating-temperature range of 0-55 °C.
Wireless export architecture
Freeze the exact detector SKU/BOM, radio module, frequency band, antenna arrangement, SIM or gateway dependency and firmware revision. A family name alone is not sufficient.
Define what happens locally, what is transmitted, the receiving platform, account ownership, notification path, outage behaviour, data retention and the party responsible for response.
Match product fire-detection evidence and radio or telecom evidence separately to the exact configuration, legal holder, destination country and current validity period.
Documented boundary: manual Ver 1.0 states that an NB-IoT module sends data and that third parties operate associated IoT platform services. Type-test report Dz2023201944 evaluates the heat alarm against GB 30122-2013; it is not represented as NB-IoT, LoRa, 4G, 433 MHz, telecom or destination-market radio approval.
The manual lists places with dust, retained smoke or vapour, and rooms where smoke detection may be unsuitable. A project review must still confirm detector type and environmental limits.
The manual identifies locations where a fire may develop without an early smoke signature. The project fire strategy should define whether fixed-temperature, rate-of-rise or another method is required.
Kitchens, boiler rooms, generator rooms and drying workshops are examples in the manual. Local design rules, spacing and commissioning requirements remain controlling.
For Fire Alarm Retrofit Solutions for Warehouses, begin with the expected normal temperature, nuisance conditions and the fire scenario rather than selecting by radio name alone.
Application media
The supplied promotional image illustrates kitchens, food-service spaces, shopping areas, generator rooms, drying workshops and boiler rooms. It is an application reference, not a project design, placement instruction or certification statement.
Answers for buyers
The documented WANLIN-340 configuration provides local audible and visual alarm functions without a conventional panel. Any remote reporting path must be confirmed for the exact SKU/BOM.
Provide the country, application, ambient conditions, ceiling height, quantity, local-only or remote reporting requirement, packaging language and required evidence.
The manual states that sound stops and the red indicator flashes rapidly for about 80 seconds, after which the alarm can resume if the threshold condition remains.
No. Communication module, platform, label, power arrangement and evidence can vary. Confirm the controlled configuration before quotation or a formal claim.
Check detector type, spacing and coverage design, ambient temperature, nuisance conditions, mounting position, maintenance access and applicable local design requirements.
Send the country, application, ambient conditions, quantity, reporting method and evidence requirements to wanlinfirecontrol@163.com.
