Each IR-TEC PPU-300/301 power pack can supply power for up to 6 OS-551DT sensors. When more sensors are connected, multiple power packs may be required. Low Voltage Dual-Tech Occupancy Sensor OS-551DT INSTALLATION INSTRUCTIONS APPLICATION NOTES PIR sensor is more sensitive to the movements “crossing” the detection zones than “toward” or “away” the sensor unit. Avoid placing the sensor in line with the path of occupant, if possible. In general, mounting the sensor at corner area gives better detection. PIR sensor cannot “see” the movements behind obstacles, such as furniture, shelf, glass or partitions. As a general rule, ensure to place the sensor at where the occupant could have clear view of the sensor. HFD sensor may penetrate through certain types of non-metallic partition material (glass, plaster, plywood…etc) and detects the traffics outside of desired range. Ensure to adjust the HFD sensitivity to achieve optimal detection range. Place the sensor at least at 5 ft. (1.5m) away from air supply duct and fluorescent lighting to avoid false activating. For open office areas with partition which could block the sensor view to occupant movements, it is recommended to place the sensors over the intersection of multiple workstations. For large areas of open office or space, place multiple sensors so that there is overlap coverage with each adjacent sensor. 1. 2. 3. 4. 5. WIRING DIAGRAM A. Auto-ON/Auto-OFF with PPU-301 B.

The sensor combines a cutting edge Passive Infrared (PIR) sensor, a state-of-the-art High Frequency Doppler (HFD) sensor, and advanced signal processing firmware into one unit to perform superior occupancy sensing capability. The OS-551DT is ideal for the areas where motion may not be easily detectable by a single technology sensor. The OS-551DT is operated by 24V low voltage power. When PIR sensor detects the presence of occupant within its coverage, the sensor will activate a form C dry contact for a period of OFF-delay time as programmed. The delay timer will be reset if any motion is detected by either PIR or HFD sensor before delay time elapsed. An ON-delay can be enabled to prohibit short-cycle restart or unwanted load activation if the sensor is used to control HVAC operation. Both ON and OFF delays can be easily set via two rotary DIP switches on board. A potentiometer allows the HFD sensitivity adjustment. The sensor output can be set to inhibit when ambient light level is higher than the threshold programmed. The ECG analog output is available for constant level lighting control. This sensor offers numerous control options which can be enabled, or disabled via a 6-pole DIP switch on board. 3 LED’s are available to indicate the sensing status which can be disabled if necessary. A built-in buzzer can be enabled to provide audible Delay-End Warning (DEW) at the end of OFF-delay. The SmartDelay can be enabled to automatically adjust the OFF-delay based on the duration of previous occupancies. Walk-Through mode can be enabled to turn the light off 3 minutes after the area is initially occupied but with no motion detected in the next 30 seconds. The FORCE-OFF delay can also be applied if HFD sensor may detect the out-of-range motions thus result in unwanted OFF-delay extensions. The sensitivity of PIR sensor can be reduced for harsh environment.
