Low voltage switches, located in the manager’s office and warehouse, provide manual on override of all luminaires in five rows to 100% if lighting is needed after hours. Each manual switch controls a 10,000ft² zone to comply with the space control requirement of ASHRAE 90.1. The time clock in the panel provides the automatic shut off of this override after two hours. In addition, some HID luminaires are circuited for night and emergency lighting. These luminaires are not controlled and will remain on all of the time. & Code Compliance Guide ASHRAE IECC TITLE 24 1999 2003 2005 2001 2004S 2004 2006 32 Watt Stopper/Legrand W-WA4.0 0508
