Application

Smoke detection technology suitable for all building applications

Smoke detection technology suitable for all building applications

Description

The Series 200 Advanced Protocol supports more devices on the loop with extended control, configurability, and device management, allowing optimisation according to building layout and application. The 22051E optical smoke detector incorporates a redesigned detection chamber to improve responsiveness, minimise sensitivity drift from dust, and reduce unwanted alarms from insect ingress and debris.

The unit contains processing circuitry with smoothing filters to suppress transient noise and embedded algorithms to enhance false alarm immunity and detection speed. Two integral tri-colour LEDs provide 360° visual status indication, programmable for static or pulsing red, amber, or green signals. All Series 200 Advanced detectors comply with WEEE and RoHS requirements and are mechanically and electrically backwards compatible with Series 200 plus devices.

Features and benefits:

  • New mechanical platform with revolutionary chamber offering improved false alarm immunity:
    • Improved detection across multiple fire types.
    • Improved resilience to false alarms through dust.
    • Removed risk of false alarms through insects.
  • Includes Series 200 Advanced Protocol.
  • Available with or without single pole short circuit isolation with status control through the Series 200 Advanced Protocol.
  • Tri colour LED offering red, green and amber colours.
  • Rotary decade address switches.
  • Pure white colour to compliment modern buildings.
  • 100% mechanical and electrical backwards compatibility.
  • New base design to compliment the detector.
  • EN54 Certified.
