Intelligent High Sensitivity HS200 Point Smoke Detector

100x more sensitive than standard smoke sensors, the HS200 is a high gain amplifier-based intelligent smoke sensor, suited to applications where there is substantial downtime cost or a significant investment in equipment has been made.

The 72051EI High Sensitivity detector provides an extremely high sensitivity to fire conditions, by detecting the earliest particles of combustion. This is achieved by combining a patented optical chamber with advanced high-power output IR LED diode and precision optics technology, which is matched with a unique superior high gain IR receiver amplifier, enhancing the sensitivity of the device. The chamber is supported by sophisticated processing circuitry and microprocessors that feature smoothing-filter algorithms to help eliminate transient environmental noise conditions and reduce nuisance alarms.


  • High sensitivity, high power output IR LED and high gain IR receiver amplifier
  • Superior early warning performance
  • Effective response to both fast flaming liquid fires and slow smouldering fires
  • 3 stage of drift compensation algorithms
  • New mechanical platform with patented chamber to:
    • Improve resilience to false alarms through dust
    • Remove risk of false alarms through insects
  • Advanced Protocol
  • Single pole short circuit isolation with status control
  • Rotary decade address switches
  • Twin LED indicators providing 360° visibility, offering tricolour flashing options (red, green and amber colours)
  • -10°C to 55°C operating temperature range
  • Approved to EN54 – 7 (2000)
