Bottom line: Vaping moved into washrooms because that is the one room nobody supervises, so the Vape Detection Unit is tuned for short bursts rather than for the steady plume a cigarette produces. Wanlin Fire is a smoking detection alarm manufacturer and export supplier in China, covering vape and e-cigarette detector along with the heads, gateway, mounting set and monitoring platform that a no-smoking program needs in Brazil. We work directly with security and fire safety distributors, facility management companies, hospitality procurement teams, system integrators, building services contractors, school and healthcare estate buyers, and cross border trading companies looking for a stable factory partner rather than a trading office. What changed: 36% headroom against regional distributor pricing through factory direct sourcing, per-model documentation, written sensitivity plans and flexible MOQ with long-term partner stock programs. Evaluation took 19 days and covered a bench test with a lit cigarette in a closed room, a steam rejection test in a real washroom, and a review of the event log against what the site staff knew had happened.

A facilities contractor lost a building management contract over a smoking complaint he could not evidence. The next tender he bid included detection, and that is how he came to us.
Their previous approach relied on staff finding the evidence afterwards, which works about as well as anyone expects: the cigarette is finished, the window is open and the room smells faintly of air freshener.
What settled it was a test they ran themselves rather than a demonstration anybody gave them. Johan Bergstrom signed off the first E-Cigarette Detector for Hotel Rooms order covering 10 rooms in Brazil, and the specification was rebuilt around sensitivity, position and the evidence record rather than around a brand name.
They evaluated for 19 days, including a week with the cleaning schedule deliberately unchanged, because testing the device against a modified routine proves nothing. What convinced the board was not the detection rate. It was the absence of arguments, because disputes now ended with a timestamp instead of an opinion.
There is a version of this project that ends with a drawer full of disconnected devices, and a version that ends with a second order. The difference is decided before installation.
Deodorant, hairspray and cleaning spray all produce aerosol, which is exactly why this category has a reputation problem to overcome.
Field case: A Sao Paulo school had eleven unexplained fire alarm activations in one term, each one traced afterwards to vaping in the same block and none of them dealt with at the time.
This is the question that decides whether the project is specified correctly, so it deserves a plain answer. A fire smoke alarm exists to start an evacuation, and its threshold is set for a fire that is already producing substantial smoke. A single cigarette in a washroom with the extract fan running rarely reaches that threshold, and when it does, the building gets an evacuation it did not want. That is not a fault in the fire alarm: it is the correct behaviour for a life safety device.
We sell both categories, so we state this without hedging. Installing a smoking detector does not remove any fire detection obligation in Brazil, and any supplier who tells a client otherwise is selling something they should not.
The sequence matters less for its cleverness than for what each step removes from the argument later.
Sensitivity, delay to alarm and re-arm behaviour are commissioning values, not factory defaults nobody has checked. They are stated in writing for the project and recorded on the commissioning sheet.
A washing room is the hardest environment a detector can be asked to work in: steam every morning, cleaning agents every night, air freshener in between, and a door that opens onto a corridor. Getting this wrong does not produce a technical failure, it produces a device nobody wants.
Wanlin Fire is recruiting local partners for no-smoking detection and remote monitoring. Most territories remain open and distributor wanted enquiries are answered directly by the export team. Our 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 performance clause on a tender. Because heads, gateways and the platform ship from one factory, a partner can fill a container with a complete configuration under a single bill of lading.
Partners across North America, Europe, Asia-Pacific, the Middle East, Africa and Latin America run this model today. Cross border trading companies looking for a source factory are welcome to start with a sample order covering two or three configurations and move to bulk order volume once their own market testing is done.
The range is specified for real rooms rather than for laboratory conditions, which is why sensitivity appears as a commissioning value and not as a marketing number. Vaping moved into washrooms because that is the one room nobody supervises, so the Vape Detection Unit is tuned for short bursts rather than for the steady plume a cigarette produces.
The smoking detection range covers ceiling mounted heads for washrooms and work areas, vape oriented aerosol heads, gateway and cloud reporting options, the mounting kits and the commissioning software steps, so one room is protected by one configuration rather than by parts assembled from several suppliers. Part numbers are issued per configuration and stated on the datasheet supplied with the quotation.
Power options cover mains with backup, primary cells and rechargeable positions depending on the ordered configuration, and every head is addressable, carrying its own zone identity in the platform instead of relying on a position label alone. Standard specifications can be held ready to ship by a partner running its own stock, while custom label versions follow their own tooling slot. Ingress ratings such as IP65 are stated per model datasheet rather than claimed across the whole range. Whether a unit is CE certified, CE marked or UL listed for its class is a question the certificate number answers, and this file sets that check up rather than replacing it, which is what certification support means here.

| Scenario | Recommended unit | Key benefits |
|---|---|---|
| Secondary school washroom block | Vape Detection Unit | Staff are told which room, which is the difference between a conversation with two students and a search of every floor |
| School changing rooms after sports periods | Vape Detection Unit | Short bursts between lessons are caught rather than missed because the confirmation window is set for the way students actually use the room |
| Hotel room where vaping leaves no smell but triggers cleaning complaints | Vape Detection Unit | Housekeeping sees the event before the next guest enters the room, so the deep clean happens before the complaint |
| University residence hall corridor toilets | Vape Detection Unit | The pattern by floor helps the residence team decide where to put supervision rather than reacting to complaints |
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 configuration 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, 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 configuration before ordering.
Buyers comparing European, North American and Japanese brands, or weighing a local trading supplier against a factory, usually end up judging the same three points we are judged on.
No-smoking work adds requirements that ordinary product sourcing does not: the device has to survive steam and cleaning chemicals, the alert has to suit the way the site actually operates, and somebody has to be able to say plainly what the device does and does not record. Buyers comparing local trading suppliers against Chinese factories usually end up judging the same three things we are judged on: whether the sensitivity plan exists before the deposit, whether the commissioning sheet survives an audit, and whether anyone answers a technical question in writing.
| Factor | Wanlin Fire | Typical Trading Supplier | Brand Name Distributor |

The process below is the one we actually run, including the two steps that most buyers skip and later regret. A standard order then follows 8 steps:
These three comments came after handover rather than at the quotation stage, which is when they mean something.
A: This is the question that decides whether the project survives the first term, so we answer it carefully rather than simply claiming success. Aerosol signatures differ in particle size distribution and decay behaviour, and the unit is tuned for those differences. What we recommend is a trial in your own building with the sprays your students actually use, because that tests our claim on your site instead of in our factory.
A: Cleaning agents produce strong transient signatures, so the confirmation window and the re-arm behaviour are set with the cleaning schedule in mind. We also advise fitting the morning cleaning round into the sensitivity plan rather than asking cleaners to work around the device.
A: Rules on monitoring in washrooms vary by country and sometimes by state, and in many markets any form of camera or audio recording is out of the question. That is why this device reports air composition and nothing else: no camera, no microphone, no personal data. Even so, we recommend your client takes local advice and posts clear signage, and we say this before taking an order rather than after.
A: Your site decides. Some operators send it to a single duty phone, some to a supervisor group, and some straight to the campus security desk. Multi site operators usually route alerts by building so the duty officer only receives the buildings he or she is responsible for.
A: Anyone quoting a single percentage without seeing your building is guessing, so we do not publish one. What we offer instead is a sample unit to run in your own room for a trial period, which produces a real number for your environment and is a stronger argument to your client than our marketing figure.
What changed: By working directly with manufacturer Wanlin Fire, Sao Paulo Hospitality Procurement Manager Johan Bergstrom gained 36% margin headroom while keeping competitive installed pricing. With verified per-model documentation, a written sensitivity and layout plan, aerosol monitoring practice with local code submittal support, referenced to the school and workplace health guidance in force in the destination market, cloud reporting with tamper and low battery supervision, private label branding, a trial in their own building before the order and after-sales spare programs, Wanlin Fire became their long-term smoking detection supply partner in Brazil. We are a source factory actively recruiting local partners, and cross border trading companies are welcome to start with a sample order and grow into bulk order programs.
