Smart & Control Features

The SHARK4/E linear washdown vapor tight supports standard wired dimming and optional field-programmable sensing and wireless automation:

• 0–10V Continuous Dimming (Standard): Dims smoothly down to 10% on standard 0–10V DC low-voltage control circuits. Compatible with commercial dimmers and centralized building automation systems (BAS).
• Lightcloud & Lightcloud Blue Wireless Control (Optional Configurations): Available in Lightcloud Enterprise and Lightcloud Blue Bluetooth mesh configurations for wireless dimming, ON/OFF control, color tuning, schedules, and SmartShift via mobile app.

Compatible sensor options in the SHARK family include Passive Infrared (/PIR/E, max 40 ft mounting height, 40 ft detection diameter) and Microwave (/MVS/E, max 50 ft mounting height, 50 ft detection diameter), as well as PIR20[B][/LCB] and MVS20[B][/LCB] sensors (20 ft detection diameter mounted at 9 ft, sold separately). Field adjustments for non-Lightcloud sensors require the handheld multi-sensor remote control (catalog # MSR1, sold separately).

Electrical
