Erik Johansson, a Hotel Group Facilities Buyer in Zurich, started with a single hotel pilot and needed a supplier that could scale from 200 detectors to 20,000 without changing platform. The retrofit project was switching from conventional zones to an addressable loop, which changed both the panel budget and the wiring schedule the consultant had drawn.
Once the pilot site data came back, Erik Johansson selected Wanlin Fire as their fire detection equipment manufacturing partner. The decision came down to documentation, delivery dates and a factory that would print the buyer part numbers on every carton without redesigning the device.
When the surveyor in Switzerland asked for maintenance records, the event log from the Zurich site was exported in one afternoon, device addresses included.
The real cost of cheap detection equipment shows up after installation: disabled devices, failed surveys and owners who stop trusting the system because it cried wolf twice. A school in Zurich replaced its glass call points after a pupil shattered one during a drill; replacement glasses were out of stock and the corridor ran without a legal trigger point for days.
Field case: A university estate in Zurich switched to resettable element call points across 12 buildings; the maintenance team stopped ordering glass spares and drill resets dropped to minutes.
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.
The Break Glass Fire Alarm Button is assembled in the Shenzhen factory with a drift-compensated sensing chamber and per-unit smoke box testing as standard, which is why contractors in Zurich install it in occupied buildings.

The fire alarm OEM process starts with a short qualification call about building types, detector classes, wiring standard and the certification route used in your market. A standard OEM project then follows 8 steps:
Contractors who moved from European distributor sourcing to factory-direct fire detection describe the difference in delivery dates and documentation:
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.
Key result: By working directly with manufacturer Wanlin Fire, Zurich Hotel Group Facilities Buyer Erik Johansson achieved 36% higher margins while offering competitive pricing.
