The Big Ideas PDA-101-M is a sophisticated 2-channel motion and presence detector, proudly engineered and designed in Australia for high-performance indoor sensing. Utilizing a dual-technology approach, it combines high-sensitivity Passive Infrared (PIR) with Acoustic Detection to ensure seamless coverage in complex layouts. This makes it the ideal solution for bathrooms with cubicles, where acoustic monitoring maintains lighting even when line-of-sight is obstructed.

The unit features a primary output capable of switching up to 200W of LED or 2000W resistive loads. Uniquely, it includes a secondary 5A volt-free contact, providing the flexibility to switch either 240V AC or sub-30V DC circuits. This second channel is perfect for integrating with BMS systems, HVAC controls, or secondary low-voltage signaling, allowing for total room automation from a single ceiling-mounted device.

Designed for durability and precision, the PDA-101-M offers adjustable sensitivity and time-delay settings to suit specific environmental requirements. Its Australian-engineered circuitry is optimized to manage the high inrush currents of modern LED drivers, offering a reliable, “fit-and-forget” solution for facility managers seeking to eliminate “dead zones” while maximizing energy efficiency.
