The introduction of Smoke snesor


The railway smoke sensor is intelligent sensors that utilize a state-of-the-art thermistor sensing circuit for fast response. These sensors are designed to provide open area protection with50 foot spacing capab-ility as approved by UL 521. fixed temperature alarm. it is a high temperature sensor with 190°F fixed temperature alarm. Two LEDs on each sensor light to provide 360° visibility of the sensor indication. The LEDs can be latched ON by code comma nd from the panel for an alarm indication. The LEDs can also be unlatched to the normal condition by code command. Remote LED annunciator capability is available as an optional accessory. The sensor require compatible addressable communications to function properly. 


Product Functions & Advantages

  • Fire and Smoke Early Warning
    The detector monitors smoke concentration and abnormal temperature changes in locomotive compartments, helping identify fire risks at an early stage.

  • Reduced False Alarm Rate
    The red/blue dual-light smoke detection design helps differentiate dust, water mist and smoke, improving alarm accuracy in dusty or vibration-prone railway environments.

  • Reliable Temperature Alarm
    Dual thermistor design enhances temperature detection stability and provides double protection for high-temperature abnormality monitoring.

  • Easy Onsite Installation
    The address dialing function allows maintenance personnel to configure device addresses directly onsite, improving installation efficiency and reducing commissioning workload.

  • Stable CAN Bus Networking
    CAN communication enables multiple detectors to connect reliably with the fire monitoring controller, supporting centralized alarm management.

  • Strong Anti-Interference Capability
    Separate power and signal wiring design improves electromagnetic compatibility, making the detector suitable for locomotive onboard electrical systems.

  • Low Power Consumption
    Rated power is less than 1W, supporting continuous operation with low energy consumption.

  • Suitable for Locomotive Fire Protection Systems
    Can be used as a front-end fire detection unit in locomotive fire monitoring, early warning and fire extinguishing system solutions.
