The DSC PG9872 is wireless PowerG ceiling mounted PIR motion sensor with a 20m / 65 ft diameter detection zone, designed for PowerG compatible security systems.


Product Features:

  • Delivers 360° motion detection from a ceiling-mounted device
  • Fully secures large spaces with detection coverage up to 20m (65.6ft) in diameter
  • Ensures reliable performance using built-in PowerG leading-edge wireless intrusion technology with two-way communication (Frequency Hopping Spread Spectrum FHSS-TDMA technology)
  • Advanced True Motion Recognition™ algorithm differentiates between intruders and other disturbances which may cause false alarms
  • Fast installations using link quality LED indicators
  • Easy pull-tab auto-enrollment
  • Motion and temperature detector in one, when enrolled as part of the PowerSeries Pro system
  • Presence detection mode - active 15 minutes after installation (power-up) and then only when the panel is in Disarm mode
  • Security detection mode - operates as a normal motion security detector
  • Built-in link quality indicators eliminate the need for the installer to physically approach the control panel and reduce installation time
  • The device supports temperature and light level reports to compatible alarm systems that support temperature and light sensors
  • Tamper protection
  • Compatible with PowerSeries Neo, PowerSeries Pro, and Qolsys panels
  • Backed by DSC's 1-year limited manufacturer's warranty.
