Samuel Young, a Historic Site Facilities Manager based in Rome, had spent months sourcing wireless co detector for heritage buildings products for the Southern Europe market. Across Southern Europe, heritage retrofit tenders are being won with documented wireless systems, so the sourcing decision shapes cost, delivery speed and after-sales for years.
After comparing suppliers for 3 months, Samuel Young selected Wanlin Fire (Wanlin Group) as their heritage fire protection OEM manufacturing partner. The shortlist narrowed quickly, and the final call rested on:
Sample burn-in ran 10 days on 40 devices across three building types, and all 40 passed with stable mesh links and zero false alarms before the mass order was placed.
Site owners across Italy are learning that the cheapest detector is the most expensive one once retrofit damage, false alarms and missed fires are counted. A temple in Italy running a heating plant inside a 242-year-old wall void had no CO sensing; a flue fault over 16 hours would have put the whole dormitory at risk overnight.
Field case: A monastery in Rome installed HF-CO units around its boiler room after a near-miss; the detector alarmed at night, the duty officer was notified within 25 seconds, and ventilation was corrected before anyone was affected.
Why it matters for Italy buyers:
Wanlin Fire provides flexible OEM and ODM services for customers who want to build or expand their own heritage fire protection product lines, retrofit programs or local service brands. Our customization capabilities include:
Whether you need an existing HF-200 system under your own brand or a customized heritage fire protection line developed for a specific market, our team can work with you from device selection through mass production.
Wanlin Fire builds the Wireless CO Detector for Heritage Buildings around non-invasive wireless mesh technology precisely because heritage buildings cannot be drilled and rewired like modern structures - three things every heritage buyer checks before signing a supply agreement.

A standard OEM project then follows 8 steps:
Notes from verified partners across Southern Europe and other markets:
A: In sleeping areas, rooms with fuel-burning appliances, boiler and plant rooms, and near attached garages - at head height or per manufacturer guidance for the specific appliance.
A: Standard units alarm at 30ppm within 60 minutes, 50ppm within 60 minutes, 100ppm within 10 minutes and 300ppm immediately, following EN 50291 profiles on applicable models.
A: Yes. Models with a digital display show the live CO reading, which helps facility teams identify chronic low-level leaks before they become dangerous.
A: The detector forwards the event over the mesh to the HF-200 panel and cloud platform for app, SMS, email or voice alerts, so an overnight CO build-up reaches the duty officer immediately.
A: Electrochemical sensors typically run 5-7 years; the detector reports end-of-life to the panel, and a replaceable-sensor program is available.
