Installation & Operation
The Enerlites MDC-50V-W installs easily on ceilings and operates on 120-277VAC line voltage. The dual-technology sensor combines PIR and ultrasonic detection for superior accuracy—PIR detects heat signatures from moving occupants while ultrasonic detects motion through sound waves, providing comprehensive coverage even in challenging environments. The 360° field of view provides 1200 sq. ft. PIR coverage and 1000 sq. ft. ultrasonic coverage for complete space monitoring. Choose between six trigger logic modes to optimize detection based on your application. The adjustable time delay ranges from 30 seconds to 30 minutes, or select Autoset mode for intelligent adaptive timing. The ambient light level detection prevents the sensor from turning lights ON when sufficient natural light is available, maximizing energy savings. Adjustable PIR/US sensitivity settings allow fine-tuning for optimal performance. The DIP switch simplifies configuration, while LED indicators provide visual confirmation of detection activity. The zero-crossing function extends relay life and reduces electrical noise.

Frequently Asked Questions
What is the difference between an occupancy sensor and a vacancy sensor?
What is the difference between an occupancy sensor and a vacancy sensor?
Motion sensor switches utilize infrared radiation to monitor their surroundings. They emit energy forms such as light, microwaves, or sound to detect changes caused by movement. Most systems used in lighting and security are passive, meaning they primarily detect the infrared energy emitted by warm objects like human bodies.
Are occupancy sensors compatible with LED bulbs?
Are occupancy sensors compatible with LED bulbs?
Occupancy sensors and vacancy sensors are both used for detecting presence in a room, but they operate differently. Occupancy sensors automatically turn on the lights when someone enters a room and turn them off when no presence is detected after a set period. In contrast, vacancy sensors require someone to manually turn on the lights, but will automatically turn them off when the room is empty.
Do these sensors require a neutral wire?
Do these sensors require a neutral wire?
The primary distinction between a motion sensor light switch and a traditional light switch lies in their methods of activation. A traditional light switch requires manual operation to turn the lights on or off. Conversely, an occupancy sensor automatically activates the lights when someone enters the room and turns them off when it no longer detects any presence.
Can an occupancy sensor be used in a bathroom?
Can an occupancy sensor be used in a bathroom?
Occupancy sensors are designed to detect the presence of individuals or animals in a space and activate the lights accordingly, which can be combined with daylight sensors to enhance energy efficiency. On the other hand, daylight sensors adjust the lighting based on the natural light available, reducing the use of artificial lighting when not necessary.
Why do the lights turn off while I’m still in the room?
Why do the lights turn off while I’m still in the room?
Yes! Most motion sensors have adjustable sensitivity settings. This allows you to fine-tune the device to prevent false triggers or increase responsiveness in larger spaces.
