Why Choose the Finder 18.5D.8.230.0000 PIR Movement and Presence Detector?

The Finder 18.5D.8.230.0000 is an advanced PIR movement and presence detector with DALI interface designed for intelligent indoor lighting control. Part of the Finder 18 Series, it combines movement and presence sensing, ambient-light measurement and DALI lighting control to provide efficient automatic illumination in offices, classrooms, workplaces and other commercial buildings.

Operating from a 110–230 V AC, 50/60 Hz supply, the detector can directly control up to 8 DALI electronic control gear (ECG) units. It provides two detection zones when installed at approximately 3 m height: an 8 × 8 m movement zone for transit or higher-activity areas and a more sensitive 4 × 4 m presence zone for areas where occupants may remain relatively still.

Three selectable lighting-control functions provide flexibility for different environments, including daylight-linked constant light level control, ON/OFF operation with early warning, and ON/OFF operation with early warning plus courtesy lighting. An adjustable ambient-light threshold of 10–800 lx, adjustable PIR sensitivity and selectable turn-off delay from 10 s to 35 min help optimise comfort and energy efficiency.

Key Advantages

  • Integrated DALI interface for intelligent lighting control.
  • Direct control of up to 8 DALI ECG lighting ballasts.
  • Combined PIR movement and presence detection.
  • 8 × 8 m movement detection zone at approximately 3 m mounting height.
  • 4 × 4 m presence detection zone for detecting lower levels of occupant activity.
  • Daylight-linked constant illuminance control helps reduce unnecessary energy consumption.
  • Adjustable 10–800 lx ambient-light threshold.
  • Adjustable PIR sensitivity and selectable turn-off timing.
  • Multiple installation options for convenient integration into indoor ceilings.

Key Features

  • Finder 18 Series movement and presence detector.
  • DALI control interface compliant with EN 62386.
  • 110–230 V AC, 50/60 Hz supply.
  • Controls a maximum of 8 DALI ECG units.
  • Movement detection area of 8 × 8 m at 3 m installation height.
  • Presence detection area of 4 × 4 m at 3 m installation height.
  • Adjustable ambient-light intervention threshold of 10–800 lx.
  • Selectable turn-off delay from 10 s to 35 min.
  • Adjustable PIR detection sensitivity.
  • Daylight-linked constant light level control.
  • ON/OFF lighting control with early warning.
  • ON/OFF control with early warning and courtesy light level.
  • Push-In terminals for convenient wiring.
  • IP40 degree of protection.

Intelligent DALI Lighting and Presence Control

The Finder 18.5D.8.230.0000 combines PIR occupancy detection with ambient-light measurement and DALI control. In its daylight-linked constant light mode, the detector can regulate artificial lighting according to both occupancy and available daylight, increasing or reducing lighting output to maintain the required illumination level while helping minimise energy consumption.

Three selectable operating strategies allow the detector to be configured for different environments. Alongside constant-light regulation, it can provide ON/OFF control with an early warning before switch-off or ON/OFF control with early warning and a courtesy light level. Its separate movement and presence zones make it suitable for both circulation areas and workplaces where occupants may remain seated for extended periods.

Typical Applications

  • Office and workplace DALI lighting control.
  • Classrooms, schools and educational buildings.
  • Meeting rooms and conference facilities.
  • Commercial building lighting automation.
  • Corridors and circulation areas.
  • Daylight-linked energy-efficient lighting systems.
  • Workspaces requiring sensitive presence detection.
  • Indoor DALI lighting installations with up to 8 ECG units.
