TL;DR: For schools, yards and heritage walls, the WL-MC11 carries resettable-element operation in a weatherproof surface housing, resets by an element swap, and survives years of 18-month-backed service. Wanlin Fire is a professional fire detection and alarm equipment manufacturer in China, providing OEM, ODM and private-label manufacturing services for fire alarm distributors, electrical wholesalers, fire safety contractors, M&E consultants, facility managers, system integrators, tender specialists and global project customers. What changed: 30% margin improvement for importers and trading partners through factory-direct sourcing, per-model CE / RoHS documentation, EN 54 aligned test reports, CPR declaration-of-performance support where applicable and custom private-label programs. Fire detection product lines (WL-series platform) cover photoelectric, heat, multi-sensor, beam, aspirating and duct sensing with conventional, addressable, wireless and interconnected versions, flexible MOQ, shipping FOB, CIF or DDP to EU and global destinations.

Femke Bakker runs fire safety procurement for a group that operates in Sofia and two neighbouring provinces, so EN 54 paperwork and stock reliability mattered more than the lowest quote. The apartment blocks in Sofia still ran 1990s zone panels, and the latest insurance survey gave the owner association 12 months to upgrade.
Once the pilot site data came back, Femke Bakker selected Wanlin Fire as their fire detection equipment manufacturing partner. What closed the deal was a smoke box test report from the factory bench, plus the panel accepting the buyer protocol card during the factory visit.
Load testing at the factory showed every detector head passing the smoke box test on both sensitivity grades, which became the deciding factor in the audit report.
Before picking a fire detection supplier, a buyer in Sofia should compare how each candidate handles drift compensation, EN 54 paperwork and delivery reliability. A hostel in Sofia kept resetting a broken call point with tape after false activations, and the surveyor condemned the whole floor during the annual inspection.
Field case: A contractor in Sofia fitted weatherproof call points at the loading docks and the yard, and the first winter storm no longer left the outdoor route untriggerable.
Why it matters for EU buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own fire detection product lines for European markets. Our customization capabilities include:
Whether you need an existing WL-series device under your own brand or a customized detection line developed for your market, our team can work with you from model selection through mass production.
Wanlin Fire builds fire alarm equipment around three things buyers actually measure: stable sensitivity over years, paperwork that passes surveys and delivery dates projects can plan around.

The OEM process for a Bulgaria importer starts with a market and standard survey, then moves to samples, container QC and documentation onboarding. A standard OEM project then follows 8 steps:
Importers who moved from brand reselling to factory-direct supply in Bulgaria usually mention the same shift.
A: After a drill or a false activation, a key resets the element in seconds and the route stays legal. Break-glass versions need a spare glass on site, and schools report weeks of delay when spares run out.
A: Yes, the IP65 surface housing covers yards, loading docks and external escape routes where flush indoor units would fail the weather test.
A: Yes. On a loop panel the WL-MC11 registers as a point address, so the fire brigade receives the exact door or gate instead of a zone guess.
A: A 24V DC monitored circuit in conventional systems, or the loop pair in addressable systems. The SPDT contact drives local sounders or interfaces for third-party systems.
A: Neutral units start at 300 pieces; branded units with custom markings start at 500 pieces. Standard lead time is 25 to 35 days depending on quantity and marking work.
