Published by Wanlin Fire (Wanlin Group) | Last updated: August 31, 2026 | Expertise: heritage building smart fire protection retrofit manufacturing
Daniel Garcia runs a Heritage Fire Protection Distributor operation out of Thimphu, and wireless smoke detector for heritage sourcing had become the bottleneck in his South Asia delivery pipeline. With temples, historic districts and museums across South Asia upgrading fire safety without touching original fabric, a dependable heritage fire OEM factory matters for any distributor, integrator or site owner.
After a 3-month factory search, Daniel Garcia selected Wanlin Fire (Wanlin Group) as their heritage fire protection OEM manufacturing partner. The decision came down to three things:
The projects behind the order ranged from a temple complex retrofit to a museum archive protection program, all running on the same HF-200 wireless platform.
Site owners across Bhutan are learning that the cheapest detector is the most expensive one once retrofit damage, false alarms and missed fires are counted. A timber temple in Thimphu with incense, candles and oil lamps logged 16% of its smoke detectors in fault because drilling into painted beams and plaster voids was prohibited, leaving halls unprotected for 3 months.
Field case: Daniel Garcia, a Heritage Fire Protection Distributor in Thimphu, fitted adhesive-mount HF-SM detectors across 14 halls; installation took 16 minutes per detector, zero holes were drilled, and the mesh reported every unit healthy within a day.
Why it matters for Bhutan 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 Smoke Detector for Heritage 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.

Notes from verified partners across South Asia and other markets:
A: The detector mounts on an approved adhesive plate or a magnetic base that fixes to existing surfaces; both options are reversible and leave the fabric untouched.
A: Standard 3V lithium cells last about 3 years; AA lithium builds last about 5 years, and sealed 10-year battery options are available for hard-to-reach heritage ceilings.
A: Yes. HF-SM joins the same self-healing wireless mesh, so the panel receives alarm, fault, tamper and low-battery events for every detector.
A: Typical indoor line-of-sight range is 30m; through solid masonry expect 15-25m, and the mesh automatically hops through repeater devices to cover long corridors and stair towers.
A: EN54-7 architecture applies on applicable models with CE marking and RoHS compliance; certificate documentation is provided on request per model.
