WattStopper FSP-211 High Low PIR Occupancy Sensor

The WattStopper FSP-211 High/Low PIR Occupancy Sensor is a fixture-integrated passive infrared (PIR) device that automatically controls lighting based on occupancy and available daylight, delivering High, Low, or Off outputs with 0–10 V dimming. Manufactured by WattStopper / Legrand, this model (FSP-211) supports 120/277 VAC at 50/60 Hz with an optional 230–240 VAC version, and a load rating of up to 800 W at 120 V or 1200 W at 277 V, plus a 1/6 HP motor rating. Its IP66 enclosure and broad operating temperature range (-40°F to 167°F / -40°C to 75°C) enable durable indoor or outdoor use, while daylight harvesting and occupancy-based control help reduce energy consumption. The sensor offers adjustable time delay from 30 seconds to 30 minutes and is designed for fixture-mounted installation with a 0–10 V dimming output; configuration can be performed using the FSIR-100 Wireless Configuration Tool. Common applications include parking garages, parking lots, warehouses, manufacturing facilities, exterior lighting, commercial buildings, educational campuses, healthcare facilities, and other energy-management installations where automatic dimming and occupancy-based lighting control are required to improve efficiency and lower operating costs.
