LRD-309S

Line Voltage SmartDIM Occupancy Sensor

Overview

IR-Tec’s LRD-309S is a low-profile, fixture integrated occupancy sensor designed to control 0-10V dimmable ballasts and LED drivers. This 2-way, remote-programmable sensor is capable of providing four different occupancy sensing control schemes with fully adjustable multi-level high/low StepDIM or SmartDIM control to the integrated fixtures. SmartDIM is a state-of-the-art automatic dimming control technology developed by IR-TEC, which enables the sensor to maintain the overall ambient light level within the preset range through a smooth, flawless continuous dimming control to the connected lighting. The LRD-309Sm also employs an exclusive Hybrid Switching technology to allow switching the LED driver with high inrush current, up to 500,000 cycles.

The sensor will turn on the integrated lighting or ramp up to the programmed high dim or SmartDIM level when it detects the presence of an occupant or vehicle, and automatically dim the light down to the low level or shut off after the area is vacated for a period of time. The sensor can be operating even in the coldest of environments down to -40°F/°C. A two-way IR handheld remote programmer (SRP-280) allows you to easily configure sensor control schemes and settings, or download the existing settings of the sensor mounted up to 50 ft high from the floor. Four EZ-SET profiles can be stored in the SRP-280 for quick setup and parameter adjustment of multiple sensors. The LRD-309S sensor can be integrated with an OEM lighting fixture to provide multiple occupancy sensing control schemes with multi-level or continuous dimming by sensing the presence and movements of the occupant and the daylight available in the space. A basic wiring diagram is included at next page for reference. Consult with an IR-TEC team member if a more complex control is required.
