TL;DR: The Dual Sensor Smoking Alarm exists because the first casualty of a badly tuned washroom detector is the detector itself, which gets disabled within a month and leaves the room unprotected. Wanlin Fire is a smoking detection alarm manufacturer and export supplier in China, covering dual sensor smoking alarm with false alarm reduction along with the heads, gateway, mounting set and monitoring platform that a no-smoking program needs in Indonesia. 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. Net result: 34% margin headroom through factory direct sourcing, per-model documentation, written sensitivity plans and flexible MOQ with long-term partner stock programs. The evaluation period was 28 days and ended with a commissioning record rather than a purchase order, because the client needed the document for the insurer before ordering.
Published by Wanlin Fire | Last updated: September 20, 2026 | Expertise: cigarette and vape aerosol detection, washroom and no-smoking enforcement, false alarm rejection, wireless reporting and export manufacturing
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 own technicians had to be able to install and maintain it, which put anything with a gateway, a server or a licence fee at a disadvantage from the beginning.
The decision came down to documentation rather than to price. Sarah Whitfield signed off the first Dual Sensor Smoking Alarm with False Alarm Reduction order covering 11 rooms in Indonesia, and the specification was rebuilt around sensitivity, position and the evidence record rather than around a brand name.
Evaluation took 28 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. The interesting part came later. Because every event was logged with a room identity, the operator could see that the problem rooms were all next to the fire exit, which nobody had suggested.
Every buyer in this category has the same first conversation, and it usually happens about six weeks after a cheap batch was installed.
Every site that has tried washroom detection once and abandoned it approaches the second attempt with very different questions.
Field case: A restaurant found its detectors alarming on cooking aerosol drawn back through the return air path, and the fix was a comparison test rather than a sensitivity change.
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 Indonesia, 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 units below are built around one idea: the device has to stay useful in a room that is cleaned daily, steamed hourly and used by people who do not want to be watched. The Dual Sensor Smoking Alarm exists because the first casualty of a badly tuned washroom detector is the detector itself, which gets disabled within a month and leaves the room unprotected.
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.
| Parameter | Wanlin Fire Specification |
|---|---|
| System reference | Dual Sensor Smoking Alarm |
| Product category | Dual sensor smoking alarm built for sites that have already abandoned one detector because of nuisance trips |
| Detection target | Cigarette and tobacco aerosol, distinguished from steam, deodorant aerosol and cleaning spray by the combined behaviour of two sensing paths |
| Sensing element | Two independent sensing paths read together: particulate behaviour and gas response, with the comparison logic stated in the datasheet |
| Alarm logic | Alarm requires agreement between the two paths inside the confirmation window, so a single path event does not raise the alarm |
| Connectivity | Wireless link to the gateway or direct WiFi depending on the ordered configuration |
| Reporting path | Local alert plus event record with the reason code, which is what lets a maintenance team see whether a head needs cleaning rather than replacing |
| Power supply | Mains with backup or battery configuration, both stated per model datasheet |
| Housing and mounting | Ceiling mount housing with an insect screened chamber access cover for food service sites |
| Installation pattern | One unit per zone with a spacing plan issued against the reflected ceiling drawing |
| Configuration and sensitivity | Sensitivity band, alarm delay, re-arm behaviour and nuisance suppression set at commissioning and recorded on the commissioning sheet |
| Maintenance and self test | Automatic self-check with fault, tamper and low battery supervision reported to the platform where fitted, test interval set by the site operator |
| Export documentation support | Technical file prepared to support local code submittals and national registration by the importer of record, including CE, UKCA, FCC and UL route file sets where they apply |
| Certification documents | CE, RoHS and REACH documentation per applicable model, certificate number provided on request |
| OEM and ODM options | Logo, part number, packaging, manual languages, label artwork and firmware identity string configurable |
| Full datasheet | Complete electrical, radio and environmental data provided per model on request |
| Warranty | 36-month |
| Scenario | Recommended unit | Key benefits |
|---|---|---|
| Site that has already disconnected its existing detectors | Dual Sensor Smoking Alarm | Dual path agreement is what makes the reinstall politically possible, because the operator has evidence the second attempt behaves differently |
| Restaurant and kitchen adjacent washrooms | Dual Sensor Smoking Alarm | Cooking aerosol in the return air path is handled by comparing the two readings rather than by turning sensitivity down until nothing alarms |
| Gym changing area with steam and body spray | Dual Sensor Smoking Alarm | Both products are common in the same room, so the signature comparison is the only practical way to keep the device armed |
| Transport terminal toilets with continuous cleaning rounds | Dual Sensor Smoking Alarm | Reason codes tell the team whether an event was a cleaning product or tobacco, which is what stops the device being muted |
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.
There is no shortage of suppliers who can send a quotation. The shortage is of suppliers who can send a specification.
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 |
|---|---|---|---|
| Manufacturing depth | Tooling and lead time implications of any customisation are stated before quotation rather than discovered after the order | Trading office, outsourced production | Brand owner, no project work |
| Document transparency | EN 54 and EN 14604 route papers are supplied where the device class and the destination require them, and the technical file states clearly where the smoking detection unit sits alongside rather than inside that route | Family level PDF files, customs risk | Brand level only, no model files |
| Design support | Head count, spacing and sensitivity band issued in writing from your reflected ceiling plan | Price list only, position left to the installer | Standard package, no site layout |
| False alarm planning | Sensitivity set with your cleaning round and your season in mind | Factory default nobody has reviewed | Fixed setting, no site tuning |
| Customization | Private label firmware identity strings and device naming conventions set per partner, which is what lets you build your own catalogue numbering | Limited to stock models | No customization, fixed SKUs |
| Price (factory direct) | Tiered factory pricing with 34% margin headroom typical for repeat partners | Low unit price, unstable sourcing | Brand markup of 2 to 4 times |
| Delivery reliability | Confirmed production slots, batch inspection records, lead time stated per configuration at quotation | Unpredictable, no line access | Stock dependent, allocation risk |
| Spare parts | Spares and service kits held against your forecast | No spares program | Brand spares at brand pricing |
| After-sales | Volume tiers quoted transparently so you know the price at your next order step before you reach it | No after-sales, high failure risk | Limited, ticket based support |
Our export programs suit security and fire safety distributors, facility management companies, hospitality and healthcare procurement teams, integrators, contractors, school and campus estate buyers, transport terminal operators, importers and tender coordinators.
This is the order we recommend, and the sequence matters because each step removes a question that would otherwise surface during commissioning. A standard order then follows 8 steps:
What partners say afterwards is usually about the second order rather than the first.
A: A single path device sees one quantity and compares it with a threshold, which means any aerosol that looks like tobacco trips it. Two paths see the same event differently, and the alarm needs agreement inside the confirmation window. Steam and deodorant separate from tobacco smoke in that comparison rather than in the threshold.
A: The band is configurable, and we set it with you at commissioning rather than leaving a dial in the ceiling that nobody has documented. Where your team wants to change it later, we provide the procedure and the record sheet, because an undocumented adjustment is an audit finding waiting to happen.
A: The unit reports a drift or contamination fault rather than silently degrading, because a chamber that is dirty is the most common cause of both false alarms and missed events. That fault is what turns chamber cleaning into a scheduled task instead of a guess.
A: Chamber cleaning intervals depend entirely on the environment: a gym changing room and a corporate washroom are not comparable. We supply the recommended interval for the ordered model and your site adjusts it from the reason code history the platform collects.
A: It is supplied with a written specification sheet rather than a brochure, including what is sensed, what is configurable, what is documented and what still needs local verification. Tender buyers usually need exactly that distinction: fact, configuration item and open item listed separately.
Net result: By working directly with manufacturer Wanlin Fire, Jakarta Hotel Engineering Manager Sarah Whitfield gained 34% margin headroom while keeping competitive installed pricing. With verified per-model documentation, a written sensitivity and layout plan, multi criteria detection practice with local code submittal support, referenced to the detector performance guidance in force in the destination market and to the commissioning record issued with the project, 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 Indonesia. 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.
