Sophia Martinez, a Smart City Safety Platform Partner based in Thimphu, was tired of juggling three different vendors for wireless smoke detector for heritage and wanted a single factory-direct partner for the South Asia market. Across South Asia, heritage retrofit tenders are being won with documented wireless systems, so the sourcing decision shapes cost, delivery speed and after-sales for years.
After a 3-month factory search, Sophia Martinez selected Wanlin Fire (Wanlin Group) as their heritage fire protection OEM manufacturing partner. Three factors sealed the choice:
One deployment alone covered a historic district pilot where every listed building needed no-drill detection; another was a monastery program where detectors were mounted with adhesive bases on painted timber.
When a heritage fire in Thimphu goes wrong, it rarely fails loudly - detection gaps, false alarms and unmonitored overnight hours show up only after the event log is reviewed. A conservation survey in Bhutan counted 30 heritage rooms with no active smoke detection at all, because the listed-building consent process rejected every wired installation proposal for 21 days.
Field case: Sophia Martinez, a Smart City Safety Platform Partner in Thimphu, fitted adhesive-mount HF-SM detectors across 30 halls; installation took 39 minutes per detector, zero holes were drilled, and the mesh reported every unit healthy within a day.
Why it matters for Bhutan buyers:

Feedback from verified distribution and integration partners in South Asia and worldwide:
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.
