Olivia Brown, a Historical Building Safety Importer based in Tehran, was tired of juggling three different vendors for electrical fire monitoring device for heritage and wanted a single factory-direct partner for the Middle East market. With temples, historic districts and museums across Middle East upgrading fire safety without touching original fabric, a dependable heritage fire OEM factory matters for any distributor, integrator or site owner.
Following several rounds of factory vetting, Olivia Brown selected Wanlin Fire (Wanlin Group) as their heritage fire protection OEM manufacturing partner. Three factors sealed the choice:
The buyer's own engineers benchmarked the HF-200 against two rival platforms for mesh reliability and event logging, and the Wanlin Fire build won on both metrics at a lower project cost.
Every month, conservation teams in Tehran lose irreplaceable fabric to fires that should have been caught earlier - and the fix starts with the detection spec, not the response plan. A wiring survey in Tehran found 166-year-old circuits feeding 18% of the temple complex, with cable temperatures 37°C above ambient at two distribution boards during evening events.
Field case: Olivia Brown, a Historical Building Safety Importer in Tehran, installed HF-EF monitors on 24 distribution boards; a cable clamp logged a temperature rise to 37°C at a worn neutral, and the circuit was replaced before it ignited.
Why it matters for Iran 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.
The Electrical Fire Monitoring Device for Heritage comes off the Wanlin Fire production floor in Shenzhen, where layout design, SMT assembly, function testing, certification management and private-label packaging are handled in-house. It is built for temple complexes, museums, archives, ancient towers and historic districts.

Certification is one of the most important considerations when sourcing fire protection equipment internationally. Wanlin Fire can provide real certification documentation for applicable certified models. Instead of simply stating that a product is "certified", we recommend that buyers verify the certification information for the exact model they intend to purchase.
| Information | Details |
|---|---|
| Product | Heritage Fire Protection Equipment (HF-200 Wireless Platform) |
| Model Number | HF-EF |

Every heritage retrofit OEM project follows a proven flow that starts with your target market and ends with shipment. To receive a more accurate quotation, please provide: target country or market, heritage building type (temple, museum, archive, tower, historic district), required devices, estimated quantity, OEM requirements and connectivity requirements. A standard OEM project then follows 8 steps:
Feedback from verified distribution and integration partners in Middle East and worldwide:
A: Electrical faults cause more heritage fires than any other single source. Monitoring leakage current, arc faults and cable temperature lets you fix a failing circuit before insulation breakdown ignites timber or plaster.
A: No. The unit mounts on the DIN rail of the existing distribution board, and current transformers and temperature clamps are clipped around existing cables - the building wiring stays untouched.
A: AFDD detects dangerous series and parallel arcing, such as loose connections and damaged cable strands, which circuit breakers and RCDs do not reliably catch.
A: Pre-alarm and alarm stages go to the HF-200 panel and cloud platform for app, SMS, email and voice notification, so an overheating cable is investigated before a fire starts.
A: Yes. Models with a current transformer kit monitor 380V three-phase distribution, which suits larger temple complexes and museum plant rooms.
Key result: By working directly with manufacturer Wanlin Fire (Wanlin Group), Iran Historical Building Safety Importer Olivia Brown achieved 39% higher margins while offering competitive pricing.
