compact office 24V SR


  • Presence detector (PIR)
  • Square detection area
  • Mixed light measurement
  • Light switch output (relay, potential-free)
  • Presence switch output (relay, potential-free)
  • Automatic control of lighting and HVACas well as room monitoring function
  • Lighting control with light threshold value and self-learning switch-off delay
  • Pulse function for staircase time switch
  • HVAC control with switch-on and switch-off delay
  • Room monitoring with selective movement detection
  • The pulse function is for controlling a staircase time switch
  • Presence switch contact for HVAC control: The switching behaviour of the potential-free contact is only controlled by presence
  • The switch-on delay prevents instantaneous switch on. The contact only closes on completion of the switch-on delay
  • The sensitivity of the presence switch output is reduced in the "monitoring" position. The contact indicates the presence of people with a high degree of certainty
  • The switching behaviour of the presence detector is controlled by presence and light.
  • The self-learning switch-off delay adjusts to occupants' behaviour
  • The presence detector has mixed light measurement and is suitable for switching the following types of lamps: fluorescent lamps (FL/PL), halogen and incandescent lamps as well as LEDs
  • The square detection area allows accurate and simple planning
  • Test operation mode checks the detection area and installation
  • The parameters can either be set using the potentiometer or via the optional service remote control SendoPro 868-A
