COMET JS20 – Indoor PIR Motion Detector

COMET JS20 – Reliable PIR Motion Detector for Indoor Use, 12 V DC, Binary Output, High RF Immunity 

The COMET JS20 is a professional PIR motion detector for indoor use – the ideal solution for reliable monitoring of buildings, warehouses, offices, server rooms, or residential spaces. It detects movement from objects with human body heat and features excellent RF immunity – effectively suppressing interference from mobile phones, Wi-Fi, or other radio sources.

The signal analysis algorithm ensures high sensitivity with minimal false alarms. The detection rate can be adjusted to increase immunity in challenging environments (e.g. near ventilation systems or heaters). The detector can be mounted flat on a wall or in a corner and is powered by 12 V DC (e.g. via power supply A1510).

The binary output allows easy integration with alarm systems, Multiloggers (M13xx series), building automation, or other systems. The JS20 is the perfect addition to COMET measurement and monitoring systems – reliable, robust, and easy to install.

Why the COMET JS20 is the best indoor motion detector:

  • High RF immunity – resistant to radio interference
  • False alarm protection – electronic signal analysis
  • Adjustable detection rate – adaptable for challenging environments
  • Binary output – easy integration into alarm systems
  • 12 V DC power supply – compatible with COMET power adapters
  • Flexible installation – wall or corner mounting
  • Compatible with Multilogger M13xx – see manual
  • Robust & reliable – for continuous operation
