Container Smoke Detector Selection Guide

Match detector technology and placement to cargo, airflow, dust, condensation, vibration, maintenance access and alarm routing.

Direct answer

What should the project decide first?

Match detector technology and placement to cargo, airflow, dust, condensation, vibration, maintenance access and alarm routing. For Fire Safety Training and Guidance, the safe starting point is a written operating profile and interface schedule—not a generic detector list. Confirm cargo, airflow, power, vibration, temperature, radio, response ownership and destination-market evidence before freezing the bill of materials.

Failure modes

Risks that must be designed out

  • A room detector is not automatically vehicle-qualified
  • Power transients may exceed a nominal voltage label
  • Dust and condensation can cause nuisance alarms
  • Radio frequency and approvals vary by destination
Evidence boundary

What this guide does not claim

This page is a planning and procurement guide. It does not state that every Wanlin product or radio variant is automotive-grade, certified for a destination market, compatible with every cargo, or approved as an automatic suppression controller.

Use the exact model, SKU, BOM, firmware, radio frequency, power input, legal entity and current evidence file for any formal claim.

Reference architecture

Five controlled layers

  1. 01Documented sensing principle and limits
  2. 02Mechanical mounting suitable for the route profile
  3. 03Verified power or battery configuration
  4. 04Local alarm plus supervised receiving path
  5. 05Model-specific manuals, reports and change control
Buyer verification

Information to freeze before quotation

Operating profileVehicle type, cargo, route, duty cycle, unattended periods, cleaning, dust, moisture, temperature and vibration.
Detection objectiveCredible fire signatures, required warning time, sensing principles, alarm thresholds and nuisance-alarm controls.
Electrical interfaceNominal and transient voltage, isolation, protection, backup power, sleep current and safe shutdown behaviour.
CommunicationsLocal radio frequency, gateway protocol, 4G backhaul, coverage, buffering, supervision and data ownership.
Response workflowLocal warning, vehicle action, remote notification, acknowledgement, verification, escalation and event closure.
Evidence packModel-specific manual, drawings, BOM, reports, certificates where applicable, calibration records and acceptance plan.
Candidate system interfaces

Products must be verified by configuration

Possible building blocks may include standalone smoke or heat alarms, manual call points, sounder beacons, gateways and detector test tools. Where WANLIN-307, WANLIN-340, WANLIN-222, WANLIN-656 or WANLIN-868D is considered, request the exact variant and evidence pack. A LoRa, 4G, battery or 24 V description must not be inferred across variants.

Answer-ready FAQ

Questions procurement and engineering teams ask

What does this container smoke detector selection guide cover?

Match detector technology and placement to cargo, airflow, dust, condensation, vibration, maintenance access and alarm routing.

Does this page prove that a Wanlin model is automotive certified?

No. This engineering guide does not claim blanket automotive qualification or destination-market approval. The exact model, SKU, radio, power configuration, test evidence and intended installation must be reviewed before purchase.

What information is needed before a proposal?

Provide cargo type, vehicle drawings, operating voltage, temperature and vibration profile, airflow, target markets, fleet size, communication coverage, required interfaces and acceptance responsibilities.

How should a pilot be accepted?

Use an agreed test plan covering installation, local alarm, remote event delivery, communication loss, low power, fault handling, event acknowledgement, maintenance access and controlled documentation.
