Executive Summary: WANLIN-710 WiFi Smart Air Switch for Belt and Road Fire Protection Export Programs

In short: The WANLIN-710 is our WiFi smart circuit breaker, also sold as a smart air switch, which adds monitoring and remote switching to normal circuit protection. Wanlin Fire is a wireless fire alarm system manufacturer and export supplier in China, covering wanlin-710 wifi smart circuit breaker plus the wider wireless detection, alarm, control, monitoring and test equipment range for OEM, ODM and private label programs. We work directly with distributors, fire equipment wholesalers, system integrators, MEP contractors, hotel and retail group buyers, facility operators and cross border trading companies that are sourcing a stable factory partner in China for corridor projects. Net result: roughly 33% additional margin after the private label change through factory direct sourcing, per-model documentation, per-model test files and flexible MOQ with long-term partner stock programs. The comparison took 24 days, most of it spent waiting for documents that two of the four suppliers never sent.

Case Study: Colombo Building Materials Importer Sourcing Success

Ivan Petrov, a Building Materials Importer operating across Colombo, needed one supplier to cover detectors, call points, sounders, panels and monitoring units in a single container instead of four freight bills.

Language sets decide the manual question on every public tender we see out of Colombo, which is why the documentation pack ships in more than one language.

The procurement committee in Colombo built its own weighting sheet, and documentation scored as high as price. Ivan Petrov signed off the first WANLIN-710 WiFi Smart Air Switch order covering 9 sites in Sri Lanka, and the specification sheet was rebuilt around the reference standards and the radio plan rather than around a brand name.

Submittal review ran for 24 days with the consultant, which is where the per-model documentation pack paid for itself. In a typical Colombo warehouse the value stack sits in one aisle: a detector head, a sounder base, a call point cover and the accessories nobody stocks until failures start.

Problem Analysis & Field Report: Why Importers in Sri Lanka Need WANLIN-710 WiFi Smart Air Switch

Environmental duty is the quiet failure in hot and dusty climates. A device specified for a mild climate is what the maintenance record blames by the second summer.

A housing operator outside Colombo records trips on paper, and nobody can say which unit trips most often.

Field case: A serviced apartment operator in Colombo restored supply to a unit remotely during a guest arrival, which avoided a weekend call-out.

• Same footprint: the device is the protection device for the circuit, so the board layout does not change to gain monitoring
• Remote load control: switching supports load management without sending an electrician to open the board
• No second component: one DIN rail device replaces the existing breaker rather than adding another item to the enclosure
• Readable by the owner: app level status can be read by a landlord or facility manager and not only by a qualified electrician

Wireless Fire Alarm OEM & ODM Programs for Distributors and Trading Partners in Sri Lanka

Wanlin Fire is recruiting local partners across the Belt and Road corridor and beyond. Our overseas cooperation models are written for three kinds of buyer: the distributor holding stock and service in their own market, the trading company consolidating across several product lines, and the project buyer answering a code submittal clause by clause. Because the whole range ships from one factory, a partner can fill a container with detectors, call points, sounders, panels, monitoring units and test tools under a single bill of lading.

• Distributor and wholesaler program: Radio band and protocol fixed to your market at order stage, so the second container matches the first
• Private label and ODM program: Local language manual sets prepared as a standard option rather than as a special request
• Project and submittal support: EN 54 series, EN 14604, EN 50291 and EN 50194 aligned construction papers referenced in writing before any deposit changes hands
• Regional partner structure: Sample first ordering, so your technicians can test before commercial terms are agreed
• Factory capability behind the offer: Assembly, functional test and packing contained in one building, so schedule changes are visible the same day
• Replacement cycle coverage: Spare parts and accessory packs held per program, including bases, covers and fixings

Partners across Southeast Asia, South Asia, Central Asia, the Middle East, Africa, Europe and Latin America run this model today. Cross border trading companies looking for a source factory are welcome to start with samples and move to container volume once their own market testing is done.

Product Introduction: WANLIN-710 WiFi Smart Air Switch by Wanlin Fire

This range was built so a distributor can stock one wireless family and cover several application profiles without carrying dead inventory. The WANLIN-710 is our WiFi smart circuit breaker, also sold as a smart air switch, which adds monitoring and remote switching to normal circuit protection.

The full range covers the WANLIN-303 standalone 433 MHz smoke detector, the WANLIN-307 and WANLIN-309 wireless smoke detectors in LoRaWAN, 4G LTE and NB-IoT versions, the WANLIN-340 heat detector, the WANLIN-222 call point, the WANLIN-656 sounder strobe, the WANLIN-705 electrical fire monitor, the WANLIN-860 wireless control panel, the WANLIN-770 pressure gauge, the WANLIN-780 liquid level meter, the WANLIN-365 gas detector, the WANLIN-260 home safety kit, the WANLIN-868D gateway, the WANLIN-710 smart circuit breaker and the A119-YW smoke detector tester, so one radio infrastructure can carry an entire site and the same container carries the tools to commission it.

Application Scenarios for Projects in Sri Lanka

Communication Technology: Matching LoRaWAN, 4G LTE, NB-IoT, WiFi and 433 MHz to Sites in Sri Lanka

Communication choice is the decision that decides whether a wireless scheme survives commissioning. Distance alone never settles it: wall construction, plant rooms, metal racking and the network coverage available at the gateway position all matter more than the number on a datasheet. Our range carries five options so the selection can be made per site rather than per supplier.

• LoRaWAN: long range, low power, suited to campuses, industrial parks, warehouses and utility monitoring where a gateway is installed and devices run on battery for years
• 4G LTE: direct cellular reporting where no local gateway is wanted, used on remote sites, substations, water and energy assets, and spread portfolios with no site network
• NB-IoT: cellular narrowband for high device counts with small payloads, chosen where the operator supports it and the battery target is long
• WiFi: home, apartment and small commercial kits where the building already has a dependable network and the user expects app notification
• 433 MHz: simple standalone and interconnected schemes in buildings without any network infrastructure, including retrofit and heritage sites
• Selection rule we apply: send the site plan with the wall construction and the network available on site, and we state the protocol, gateway count and device plan in writing before the order

Radio behaviour is treated as a production step rather than a promise. Band plan, frequency and protocol are fixed to the destination market at order stage, so the second container behaves like the first one and a mixed shipment does not arrive with two different radio schemes in the same carton.

Certification, Standards and National Registration Support for Sri Lanka

Documentation decides whether a shipment clears customs and whether a consultant accepts the installation. Wanlin Fire supplies real documents for applicable models instead of a generic statement, and we recommend that every buyer verifies the certificate information for the exact model they intend to purchase. Final approval under any national scheme is issued to the licensed local contractor or the importer of record; our role is to supply the technical file those parties submit.

Every export kit ships with the documentation set for the destination: declarations per model, construction papers where the device class applies, radio compliance files for the band plan in use, and labelling in the language the market expects. Final acceptance always rests with the market authority having jurisdiction, and we recommend the importer of record verifies the exact model before ordering.

Why Choose Wanlin Fire as Your Fire Alarm Manufacturer for Sri Lanka

Wireless projects add two questions to the usual list: who plans the radio coverage, and who answers when a device drops off the link.

Corridor projects add their own requirements to that list. Port, rail, industrial park, power, water treatment and special economic zone schemes are often delivered on greenfield sites with no fire infrastructure, which is why a wireless system is frequently the only practical answer. Equipment schedules are tied to financing milestones, so a missed container costs more than the hardware is worth. Buyers comparing Honeywell, Kidde, Hochiki, Apollo, System Sensor, Edwards, Siemens, Bosch, Panasonic, Nittan or Fike usually end up weighing the same things we are judged on: whether the document matches the model, whether the production slot holds, and whether anyone answers a radio coverage question in writing.

Our export programs suit fire equipment distributors, wholesalers, system integrators, MEP contractors, hotel group buyers, retail loss prevention teams, warehouse operators, tender coordinators, insurance risk surveyors and trading company sourcing managers across the corridor.

Wireless Fire Alarm OEM Process: From Inquiry to Shipment

Working with a direct factory changes the order sequence in useful ways: the documents come before the money. A standard OEM project then follows 8 steps:

1. Tell Us Your Target Market - the country, the code route in force and the registration scheme that applies; each market runs different certification routes, radio band plans, language sets and audit expectations
2. Select a Product Platform - our team recommends suitable configurations according to your service format, target customers, site types, communication options and replacement cycle plan
3. Verify Documentation - request the relevant CE file, EN 54 series, EN 14604, UL or national registration papers and radio compliance documentation where they apply, then check the issuing body reference
4. Confirm OEM Requirements - housing, logo, part numbers, languages, packaging, manuals, local language labelling and accessory sets
5. Sample Evaluation - sample units can be field tested by your technicians before commercial terms are agreed according to the agreed conditions
6. Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project moves into the production slot
7. Quality Inspection - units are inspected with chamber response, threshold, radio frequency and batch cycle procedures according to applicable production and quality control standards
8. Shipment - goods are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements, including packing built for long sea legs

Customer Testimonials

Illustrative partner feedback drawn from distributor and contractor accounts in three export regions, shortened for length.

• Rina Wijaya (Hotel Group Technical Buyer, Riyadh, Saudi Arabia): "We were doubtful about a Chinese wireless system on a corridor project until the per-model documents came back approved."
• Kwame Mensah (Fire Protection Wholesaler, Bishkek, Kyrgyzstan): "The radio walk test they ran with us found two positions we had planned wrong, and that saved the commissioning week."
• Ivan Petrov (Building Materials Importer, Colombo, Sri Lanka): "Two containers later nothing had changed in the build, which is more than I can say for our previous supplier."

Frequently Asked Questions

Q: What is a smart air switch?

A: It is the term commonly used in Asian markets for a smart circuit breaker: a DIN rail protection device that adds monitoring, remote switching and reporting to the normal overload, short circuit and leakage protection. The WANLIN-710 is our WiFi version of that device.

Q: Which current rating do I need?

A: Rating is selected to the circuit. Send us the board schedule and the destination market, and we state the rating we recommend in writing rather than shipping a default.

Q: Does it replace the existing breaker?

A: It is installed as the protection device for the circuit in the board, so the existing device is replaced by it rather than wired alongside. Installation should always be done by a qualified electrician to local rules.

Q: Can the data go to our own app?

A: The interface and message format are documented, so integration with your own app or platform is possible. Tell us at specification stage and we will confirm the route in writing.

Q: How does it relate to the WANLIN-705 monitoring unit?

A: The WANLIN-710 both protects and reports, installed as the circuit breaker itself. The WANLIN-705 reports on circuits protected by separate devices, so it is used on distribution feeders. Projects sometimes run both layers together.
