Smart & Control Features

The SHARK4/MVS linear washdown luminaire includes a factory-installed Microwave Occupancy Sensor (MVS) and supports standard 0–10V wired dimming:

• 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).
• Integrated Microwave Occupancy Sensor (/MVS): Operates on 12VDC (30mA, 50/60Hz) with a 50 ft maximum mounting height and 50 ft detection diameter at 50 ft mounting height (-40°F (-20°C) to 140°F (60°C) sensor operating range). Default settings: Motion Sensitivity High, Brightness 100%, Hold Time 20 minutes, Standby to Dim 20%, Standby Time 1 minute, When Vacant Off, Daylight Disabled.

Adjustable sensor settings—including standby dimming level (10%/20%/30%/50%), standby time (0s/10s/30s/1min/5min/10min/30min/60min/+∞), and daylight threshold (2Lux/10Lux/30Lux/50Lux/80Lux/120Lux/Disable)—require the handheld multi-sensor remote control (catalog # MSR1, sold separately). Also available in Lightcloud and Lightcloud Blue wireless mesh configurations (sold separately).

Electrical

Powered by a Class 2 constant current driver operating on 120–277V AC at 50/60Hz. Delivers high electrical efficiency with a Power Factor of 99.9% at 120V (97.7% at 277V) and Total Harmonic Distortion (THD) of 2.80% at 120V (3.03% at 277V). Integrated 2kV surge protection protects internal electronics against transient voltage spikes. Includes pre-wired 0–10V dimming leads.
