A
power pack converts AC mains eletricity to operate DC powered occupancy sensor or sensors. It receives instructions from the occupancy sensor(s) to control one or many lighting and/or heating, ventilation, air-conditioning (HVAC) devices.

Figure 1. Power Pack Wiring Diagram
Multiple power packs can be connected to one or more occupancy sensors to control a wider range of loads that support larger scale implementations of occupancy based lighting and/or HVAC controls.

Figure 2. Multiple Power Pack Wiring Diagram
Multi-Function power pack enables additional control over occupancy based lighting with manual switching and accepts instructions from timers, building or lighting control systems to turn lights on or off.
