Section 3 Wiring 3.2 Zone Controller Wiring and Installation Zone Controller Wiring SC 32 / SC 64

All Zone Controllers can be wired serially or in parallel. To wire in series, each Zone Controller must have an identification number (ID) chosen using the DIP switches on the side of the controller (see diagram A). A single Zone Controller can be used to control multiple outputs. Conversely, multiple Zone Controllers can be used to control a single zone (for example, a ZC1 and a ZC3 controlling volume and source in a single zone respectively). In every case, each Zone Controller is given a unique ID. To wire the Zone Controllers in parallel, a ZC-BOB must be used. Each Zone Controller must have a unique identification or number chosen using the DIP switches on the side of the controller (see diagram A). To wire in parallel, each controller must be wired into a port of the ZC-BOB with a connecting wire going to the SC device (see diagram C). ZC ID (1-6) ZC ID (7-12) DIP Switch Setting 1 7 2 8 3 9 4 10 5 11 6 12 To set up the Zone Controllers, the System Architect GUI must be used. Open the GUI and click on Card Configuration within the Hardware Configuration section of the Tools menu. In this window, Zone Controllers are assigned to ZC Inputs 1-12. The input numbers on the left side of the window correspond to the ID number set using the DIP switches on the individual Zone Controllers. To select ID#2 for example, simply flip the 2 switch into the on position. ID 1-6 are connected to the top ZC input on the rear panel and ID 7-12 are connected to the bottom input. To create ID 7-12, add 6 to the ID # selected on the back of the ZC. For example, to get an ID# of 10, connect to the bottom ZC Input (7-12) and set the ID# to 4. Zone Controller Installation The installation of the Zone Controllers MUST be accomplished with the use of cable which is rated VW-1 or higher. Common NEC designations which meet this rating include: CMP, CMR, CMG, CM and CMX. 10 ®

SC 32 / SC 64 Wiring Section 3

ZC-1 - The ZC-1 is a programmable zone controller that allows input or output volume level control from a wall panel. ZC-2 - The ZC-2 is a programmable zone controller that allows input or output volume level and mute control from a wall panel. ZC-3 - The ZC-3 allows wall panel routing and Actions selection for the SC devices. ZC-4 - The ZC-4 provides contact closure routing and Actions selection for room combining or fire safety applications. ZC-Fire - The ZC-Fire is the interface to generic fire alarm relays. When fire alarm activates, the general purpose relay can typically be programmed to close if normally open or vices-versa. The ZC-fire interface unit monitors the state of the relay (n.o. or n.c.) and upon the state of change, notifies the SC 32/64, which then mutes its outputs. ZC-6 - The ZC-6 is a push-button up and down input or output volume controller. ZC-7 - The ZC-7 allows Actions selection for the SC devices. ZC-8 - The ZC-8 is used for a combination of input or output volume up/down, and four position source/program select. ZC-9 - The ZC-9 allows wall panel routing and Actions selection for the SC devices. ZC-BOB - The ZC-BOB allows parallel or home run cabling of the Zone Controllers. 11 ®

All mechanical fans have a limited life expectancy. We recommend annual inspection of fans for dust occlusion and excessive noise. Fan assemblies should be replaced after six to ten years of use. Environmental factors such as elevated temperature, dust, and smoke can adversely affect fan life. Systems exposed to these conditions should be inspected more frequently. Fan replacement can be performed either at the factory or by an experienced technician in the field. Please contact dbx Technical Support for more information on purchasing replacement parts or product service. dbx has a policy of continued product improvement and accordingly reserves the right to change features and specifications without prior notice. ® 8760 South Sandy Parkway • Sandy, Utah 84070 Phone: (801) 568-7660 • Fax (801) 568-7662 Int’l Fax: (801) 568-7583 Questions or comments?
