Best Practice Guide for Warehouses 2008 - (Page 24) WAREHOUSE Storage BUILDINGS W-WA3.0 Warehouse Area: occupancy sensing • retrofit, zoned control Control Needs Automatically turn lights on and off based on occupancy; detect forklift operation Control in logical groups Solution PIR occupancy sensors (HB series) Use low voltage sensors and power packs (BZ series); establish one control zone for each bay and rack aisle Night lights are not controlled Power from emergency panel Application Description Space Use: Dimensions: Ceiling Height: Windows: Skylights: Bulk & Rack Storage Bulk Storage 50’ x 50’ Rack Storage 12’ x 160’ Bulk & Rack Storage 35’ None None Night lights on all of the time Night lights operate during power outage Lighting Hi-bay HID lighting retrofitted one-for-one with six-lamp T5 high-output fluorescent luminaires using three two-lamp 277-volt electronic ballasts. Luminaires are mounted 32’ above finish floor. The circuiting runs perpendicular to the aisles in the Rack Storage area. Bulk & Rack Bulk Storage Partial Lighting Plan Rack Storage Partial Lighting Plan Design Solution Description The original HID lighting is replaced with T5 high-output luminaires. During the replacement, low voltage HB300-B PIR occupancy sensors are mounted to selected luminaires to provide coverage for each control zone. Low voltage wiring is added to connect all the luminaires in each zone and BZ-100E-P power packs perform the switching. Sensors in the Bulk Storage area use an HBL4 360º lens; sensors in the Rack Storage area use an HBL1 aisleway lens with a long and narrow field of view to detect forklifts in time to turn lighting on. In the Bulk Storage area, clusters of luminaires are controlled together; in the Rack Storage area luminaires in each aisle are controlled together. Night light luminaires are not controlled and remain on at night and during a power outage.
