Best Practice Guide for Warehouses 2008 - (Page 54) WAREHOUSE Storage BUILDINGS W-WAD1.0 Warehouse Area: occupancy sensing • daylighting 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 every two bays and each rack aisle Use multi-zone on/off daylighting control with switching power packs (LightSaver series); circuit for 10,000ft² control zones 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 60’ Rack Storage 12’ x 160’ Bulk & Rack Storage 35’ None 4’ x 8’ skylights covering 3.8% of gross roof area staggered layout Turn off 2/3 of the lighting when sufficient daylight illuminance is available Lighting Pendant-mounted turret industrial fluorescent luminaires with 15% uplight, 8’ long, using six T8 fluorescent lamps, and tandem-wired two-lamp 277-volt electronic ballasts. Luminaires are mounted 32’ above finish floor. Night lights on all of the time Rack Night lights operate during power outage Bulk Storage Partial Lighting Plan Rack Storage Partial Lighting Plan Bulk & WAD1.0-1.5 Design Solution Description Luminaires in Bulk and Rack Storage areas are automatically turned on and off using low-voltage HB300-B PIR occupancy sensors mounted to selected luminaires to provide coverage for each control zone. Low voltage control wiring connects the sensors in each zone and power packs perform the switching. When sufficient daylight is available, and occupancy is detected, the two outboard lamps are turned off using an LCO-203 multi-zone daylight controller. Outboard lamps are turned on when occupancy is detected and when daylight is insufficient for lighting the space. The center lamp automatically turns on when occupancy is detected, and off when the space is vacant. At night, or when there is not sufficient daylight, all lamps operate when the area is occupied. Night light luminaires are not controlled and remain on at night and during a power outage.
