Secure CO Communication, WANLIN-868D, Medan

TL;DR: Wanlin Builds Interconnected CO Programmes for Medan Hotel Groups

Wanlin builds interconnected co programmes for hotels and serviced apartments for Medan and Indonesia landlords, letting agents, housing associations, hotel and serviced apartment groups, student and senior housing operators, boiler and plant room operators, parking deck managers, RV, camper, caravan and marine builders, gas and heating contractors, safety distributors, electrical wholesalers, importers, trading companies and sourcing agents. Carbon monoxide is the risk a smoke alarm cannot see: it has no smell, no colour and no taste, it comes from any fuel-burning appliance that is poorly installed, poorly maintained or poorly flued, and it hurts the people who are asleep when it arrives. The Wanlin CO line is built around the two things that actually decide the outcome - the response curve and the alert path. Electrochemical and MEMS CO sensing declared to the EN 50291-1 time-weighted response bands and the UL 2034 bands for North America, sealed 10-year lithium cells with a declared end-of-life date, plug-in, mains and 12 V or 24 V DC variants, LCD display, voice alert and strobe output, combination smoke and CO units, and interconnection or cloud alerting over RF 433 MHz, Wi-Fi, Zigbee, Z-Wave, 4G, NB-IoT and LoRaWAN so an event in the basement sounds the unit outside the bedroom and reaches a phone. The WANLIN wireless device family - WANLIN-868D Fire Alarm Control Panel and LoRa Gateway (LoRa / Ethernet / WiFi) among them - rides on the same host where a site wants CO, smoke, gas and plant monitoring under one account. Every shipment leaves with CE, RoHS and REACH files, FCC where the destination requires it, EN 50291-1 and EN 50291-2 documentation, UL 2034 and CSA documentation for the Americas, calibration records per lot against reference CO mixtures and a commissioning record from the Medan test floor. OEM/ODM with private label, factory-direct export supply for Medan and Indonesia, and an open distributor, contractor and agent programme for 2026-2027.

Inside the Wanlin CO Detection Stack: Sensing, Power, Alerting, Compliance and Fleet

A CO alarm is a deceptively simple product to specify badly. The sensing element, the power source, the alerting method, the siting rule and the end-of-life behaviour each make or break the outcome, and they interact: a sealed cell changes the replacement cycle, interconnection changes whether anyone hears the alarm, and a mains unit with a relay output changes what the building does about it. The table below is the stack in the order a Medan buyer should read it.

Where the boundary sits: a smoke alarm is declared to EN 14604 and a CO alarm to EN 50291-1 - they are different standards measuring different things, and neither substitutes for the other. Carbon monoxide is produced by incomplete combustion; smoke is produced by the fire. Wanlin builds dedicated CO units, dedicated smoke units and combination units, and specifies per room rather than per catalogue: a combination unit where one position serves both risks, a dedicated CO unit wherever there is a fuel-burning appliance, and always a CO alarm in the room containing that appliance.

Featured programme profile this report - Boiler Room, Plant Room and Garage Profile (Relay Output, Fixed Supply): mains or 24 V units with a relay output for Medan boiler houses, plant rooms, generator rooms and enclosed parking decks: the CO channel drives an extract fan, a solenoid shut-off valve or the building management system rather than only a local sounder In a boiler room the alarm is not the point, the action is. A relay contact that starts the extract fan and closes the gas valve is what turns a reading into a response, and that is why the plant profile is specified with the output as well as the sensor.

CO Alarm, Smoke Alarm, Gas Alarm: Where the Boundary Actually Sits

This is the distinction the Medan export desk spends the most time on, and getting it wrong is how a building ends up compliant on paper and unprotected in fact. The three channels measure three different things, they are declared to three different standards, and they sit in three different places in a room. The table below is how we draw the line before a specification is written.

In one line: smoke tells you a fire has started, carbon monoxide tells you something is burning incompletely and poisoning the room, and gas tells you the supply is leaking. Wanlin builds all three channels and specifies them per room, with the combination unit used where it genuinely fits and dedicated units used everywhere else.

Competitive Comparison: Wanlin vs Other CO Alarm Sources

Sizing and Siting Guide: How a Medan Site Specifies CO Detection

Sizing a CO programme is a room question before it is a device question: the first decision is which rooms contain a fuel-burning appliance, the second is where the occupants sleep, and the third is how the alarm gets from one to the other. The reference schedule below is the one the Medan export desk issues after a site survey, based on what partners actually deploy.

Worked example for a 90-unit Medan site: roughly 120 alarms across appliance rooms, circulation spaces and sleeping levels, a CO event raised inside the declared response band at 70, 150 and 400 ppm at the default sensitivity, and a nuisance margin validated against 5 interferents found on the site before the sensitivity and siting plan is signed off. Power on this profile is specified for a 3-year service life at the declared self-test interval, with end-of-life, fault and tamper reporting so a unit that has been taken down or has expired is found by the record rather than by luck. Siting follows the rule of thumb the survey issues with the schedule: in the room containing the appliance, outside the sleeping accommodation, at breathing height or on the ceiling, not in a dead-air corner, not directly above a hob and not beside an extract intake. These are indicative figures for budgeting - the issued room schedule, siting plan and device list follow the site survey and the operator's own obligations, and those are the numbers that go into the Indonesia submission pack.

Inside the Compliance Stack: EN 50291-1, EN 50291-2, UL 2034, CSA 6.19 and the National Marks

A CO alarm programme clears a tender on paper before it clears a building. The submission has to show what the alarm is declared against in the destination market, what the radio approval is where a radio link is fitted, what the calibration and test records say and what the factory's quality system is. The table below is the stack the Medan documentation pack is built around; the certificate set and the manual in the language the inspector reads ship inside the shipment folder.

Global Carbon Monoxide Detection Market Trends

UL Standards and Engagement publishes UL 2034, the standard for single and multiple station carbon monoxide alarms in North America, which sets its own concentration and time bands and includes resistance-to-false-alarm requirements against common household interferents. For an importer, UL 2034 is the document a North American specifier, insurer or authority having jurisdiction will name before any other. UL Standards and Engagement

• The sealed 10-year cell became the default expectation: A replaceable-battery alarm is a maintenance obligation the occupant does not honour: the unit gets removed when the chirp starts, and the unit that gets removed is the one that was protecting the room. A sealed cell with a declared end-of-life date converts that obligation into a replacement cycle that a landlord, a hotel group or a housing association can actually plan, which is why the 10-year configuration now carries most of the professional volume.
• Combination smoke and CO units changed the replacement cycle: A 2-in-1 unit is not a compromise, it is a fitting decision: one housing, one mounting plate, one battery, one end-of-life date and one visit instead of two. The counter-argument is real - a combination unit cannot always sit where each sensor would ideally sit - so the honest answer is per-room: combination units where a single position serves both risks, dedicated units where the boiler room and the sleeping accommodation are in different places.
• Nuisance rejection decides whether the alarm stays on the wall: Hydrogen is the classic cross-interference gas for an electrochemical CO cell, and solvent and cleaning vapours are the classic problem for a semiconductor one. An alarm that cries wolf is taken down within a month and replaced with nothing, so the interference test at commissioning - not the datasheet headline - is what determines whether a programme survives its first winter.

Partner Success Story: Utility, Insurer or Social Housing Retrofit Programme (Volume Programme)

Partner: A social housing provider, utility or insurer-backed programme in Medan fitting CO detection across a housing stock on a fixed annual volume and a fixed installation window.
Deployed: Block-packed cartons, dwelling-level labelling, single-language manuals, consolidated certificate folder and seasonal volume allocation, Indonesia-focused configuration with local-language manuals, CE, RoHS, REACH, FCC and EN 50291 documentation packs, platform accounts provisioned at the factory and a spares programme sized to the partner's annual volume
Timeline: First production batch shipped 19-25 days after sample approval; the partner's crews commissioned 330 units and positions across the first season, with siting schedules and end-of-life records pre-loaded before delivery

"A programme of this shape lives on logistics, not on features: cartons packed by block, units labelled per dwelling, one manual language, one certificate folder, and a crew that can fit a unit in minutes without a tool kit. Wanlin packed by block, printed the dwelling reference on the carton, and held the seasonal volume against the programme calendar so the installation window did not slip." - Representative, Indonesia Program Partner

Field Report: CO Response Curve and Time-Weighted Threshold Verification - Medan

Location: Wanlin fire protection products test floor, Longgang District, Shenzhen, China
Date: July 7, 2026 | Ambient: 31 C, 82 percent humidity | Equipment under test: WANLIN-868D Fire Alarm Control Panel and LoRa Gateway (LoRa / Ethernet / WiFi) (Ethernet host configuration — wired Ethernet uplink to the site LAN and the cloud platform with BACnet and Modbus to the BMS for permanent commercial and industrial installations) with the CO detection package

Units from the Medan lot were placed in a calibration chamber and presented with reference CO mixtures in the low, mid and high concentration bands defined by EN 50291-1 and UL 2034, with the response time logged from the start of exposure to the first alarm on every concentration step and at both the default and the reduced sensitivity setting.

On-site findings: 625 recorded events were reviewed against the specification sheet; response behaviour matched the printed rating across the test window, the enclosure and ingress checks held at the documented rating, and no diagnostics or connectivity anomalies were raised. The calibration record for the lot, the CE declaration of conformity and the EN 50291 documentation set were placed inside the first carton of the batch before it closed.

"A CO alarm is not a switch, it is a curve. The standard asks for a response inside a time window that gets shorter as the concentration rises, and the only way to know whether a unit does that is to put it in the gas and time it - so that is what we publish." - Senior QC Engineer, Medan Program

Verified against the spec sheet: Alarm raised inside the declared time band at every concentration step; the response curve matched the declared profile on all runs; no unit failed to respond at the top of the range.

Application Scenarios: Where CO Detection Gets Specified

Siting, Commissioning and After-Sales: Survey, Fitting, Training and Spares

A CO programme is judged in the first winter, not on handover day: that is when the first appliance is serviced, the first interferent appears in the room and the first occupant presses hush. The table below is the support package that ships with the Medan programme - what the installer does, what the factory does, and what the maintenance crew can do without a specialist visit.

Remote support that ships with the order: cloud account provisioning before shipment, over-the-air firmware and software updates with change notification, remote diagnostics during the first commissioning, troubleshooting guides, siting drawings and test procedures in the documentation folder, and a named contact on the export desk for the life of the programme.

Frequently Asked Questions

Q: Why is a carbon monoxide alarm not the same thing as a smoke alarm?

A: They measure different things and they are declared to different standards. A smoke alarm detects combustion particles and is declared to EN 14604; a CO alarm detects carbon monoxide, a gas produced by incomplete combustion that has no smell, colour or taste, and it is declared to EN 50291-1 for household use. A blocked flue, a badly serviced boiler, a charcoal grill used indoors or a generator too close to a window can produce dangerous CO with no visible smoke at all, which is why a house with a smoke alarm in every room can still be unprotected. Most Medan programmes fit both, and use a combination smoke and CO unit only where one position genuinely serves both risks.

Q: Where should a CO alarm be fitted, and how high?

A: The rule we issue with every schedule is: one in the room containing the fuel-burning appliance, one in the hall or landing outside the sleeping accommodation, and one on each further floor. Height is not the problem people expect it to be - carbon monoxide has almost the same density as air and mixes with it, so a CO alarm can go on the ceiling, on a wall at breathing height or on a shelf, unlike a heavier-than-air LPG detector which has to sit low. What matters more is what to avoid: not in a dead-air corner behind a door, not directly above a hob or a kettle, not beside an extract intake or an open window, and not inside a cupboard. The survey sheet records the position per room and the commissioning record carries it.

Q: Sealed 10-year battery or replaceable battery?

A: For any programme where the occupant is not the buyer - rental, student housing, hotels, social housing - sealed. A replaceable-cell alarm becomes a maintenance obligation the occupant does not honour: the unit is taken off the wall when it starts chirping, and the unit off the wall is protecting nobody. A sealed cell carries a declared end-of-life date, which lets a landlord or a housing provider plan the replacement instead of discovering it. For an owner-occupied home where the resident wants a plug-in or a hardwired unit with battery backup, the replaceable and mains variants remain available, and battery backup is specified on the mains units so a power cut does not remove the protection.

Q: Do the alarms need to be interconnected, and can they be monitored remotely?

A: Interconnection is the single cheapest measure that changes the outcome, because a CO event in a basement utility room is otherwise inaudible to the occupants asleep two floors up. We supply RF 433 MHz, Wi-Fi, Zigbee and Z-Wave interconnection so one event sounds every unit on the group, and 4G Cat-1, NB-IoT and LoRaWAN variants plus a Wi-Fi cloud path so the event also reaches a phone by app push, SMS or voice call with a device identity and a room attribution. For Medan estates the connected variant is what turns a local sounder into a managed record: status, faults, tamper and end-of-life all visible without a visit.

Q: Will it false alarm? What interferes with the CO channel?

A: Hydrogen is the classic cross-interference gas on an electrochemical CO cell, and solvent, alcohol and cleaning vapours are the classic problem for a semiconductor one. Both are addressed at the cell and the algorithm level and then tested: units are challenged with hydrogen, ethanol vapour, a household cleaner aerosol and a high-humidity clean-air run, and each is logged as event or no-event at the declared interference limit. The other half of nuisance control is siting - a unit directly above a hob or beside an extract will give trouble whatever its electronics - which is why the siting plan is issued with the schedule rather than left to the installer.

Q: Can the alarm actually do something, or does it only make a noise?

A: On the plant and commercial variants, it can act. The mains and 24 V units carry a relay output that drives an extract fan, a gas solenoid shut-off valve or a building management system input, with BACnet, Modbus and MQTT paths on the connected variants, so an event in a boiler room, a generator room or an enclosed parking deck triggers ventilation and isolation rather than only a local sounder. On the residential variants the action is the alert path: interconnection and the phone notification. Both are specified per room in the schedule, because the right output depends on who is in the building and what can be shut off.

Q: We build RVs, campers, caravans or boats - what changes?

A: Everything electrical. The unit runs on 12 V or 24 V DC rather than mains, it has to tolerate a supply that swings with the charger and a cabin that gets far hotter and colder than a house, and it needs a flush-mount, vibration-tolerant housing that suits the interior trim. We supply that configuration on the EN 50291-2 route for caravans, leisure accommodation vehicles and boats, with the connector and harness options a production line expects, and we supply against the builder's line rate rather than in project batches.

Q: Which certificates and documents come with the shipment?

A: EN 50291-1 for household CO alarms with the type-test report covering the response bands, interference resistance and sound output; EN 50291-2 for the leisure and marine configurations; UL 2034 documentation for the US with UL or ETL listing where the authority requires it; CSA for Canada; EN 14604 where a combined smoke channel is fitted and EN 50194 for the combustible gas channel; CE marking with the EMC and radio equipment directives where a radio link is fitted; RoHS and REACH material files; FCC certification with Part 15 on the radio options; UKCA for Great Britain; NFPA 720 and NFPA 72, BS 5839-6 and IFC installation references; RCM, EAC, GOST, KC, PSE, CCCF, SASO and SABER, TISI, SNI, SIRIM, DTI-BPS, BFP, BIS, SABS, NOM and INMETRO as the market requires; plus ISO 9001 and ISO 14001 factory certification and NIST-traceable calibration records per lot against reference CO mixtures. Manuals ship in English, Arabic, Russian, Spanish, French, Portuguese, Indonesian, Urdu, Hindi, Vietnamese and Thai, and battery transport documentation is included for air and sea.

Q: What are the lead times, minimum order quantities and warranty terms?

A: Sample cartons typically ship within 10-15 days by air and production project batches 25-32 days after approval. OEM and private-label programmes start from low four-figure unit quantities per model, and container-level mixed-model orders are quoted per destination. The CO alarm line and the WANLIN device family carry a 3-year limited warranty (2-year on instrumentation and on the tester body), a 12-month warranty on battery packs where the cell is replaceable, the declared service life on sealed cells, 30-day DOA replacement, and a five-year spare-parts window with a documented obsolescence path for tenders that require a long service-life commitment in Indonesia.

Q: We are a distributor or a contractor - how does the territory work?

A: Talk to the export desk directly. We appoint distributors, importers and programme partners by territory and by channel, we do not appoint competing partners in the same territory without discussion, and we support the appointed partner with pricing, documentation, siting and sizing support, platform account provisioning, spares allocation, training and marketing collateral. Sourcing agents and trading companies are supplied on the same terms with neutral packaging where the end buyer should not see the factory name. Wanlin is actively recruiting local partners for 2026-2027.
