FireLite SLC Wiring Manual — P/N 51309:P4 9/17/2014 55CRF-300-6 Installation & Wiring Relay Modules7.4.2 Setting an SLC address for a CRF-300-6 ModuleEach CRF-300-6 module can be set to one of 154 base addresses (01-154). The remaining modulepoints are automatically assigned to the next five higher SLC addresses. For example, if the baseaddress is set to 28, the next five module points will be addressed to 29, 30, 31, 32 and 33.DO NOT set the lowest address above 154 (45 for the MS-9050UD, 94 for the MS-9200, MS-9200UD, and MS-9200UDLS), as the other module points will be assigned to nonexistentaddresses.7.4.3 Disabling Unused Module AddressesA shunt is provided on the circuit board to disable a maximum of three (3)unused module addresses. If two module addresses are disabled, the low-est four addresses will be functional, while the highest two will be dis-abled. For example, if the shunt is placed on ‘TWO’ and the base addressis set to 28, the module addresses will be assigned to 28, 29, 30 and 31.To disable addresses, remove the shunt from it’s storage location andsecurely place it onto the desired set of pins. See illustration.7.4.4 Wiring a CRF-300-6 Module (Form-C Relay)The figure below shows a CRF-300-6 module wired to the Control Panel.NOTE: The MS-9050UD can support addresses 01 - 50. The MS-9200, MS-9200UD, and MS-9200UDLS can support module addresses of 01 - 99. The MS-9600, MS-9600LS, and MS-9600UDLS can support module addresses 01 - 159. To set an SLC address, use a commonscrewdriver to adjust the rotary switches on the module to the desired address. See Figure 6.4 onpage 50.For use with an MS-9600, MS-9600LS, MS-9600LSC, and MS-9600UDLS, remove the stop onthe upper rotary switch.J1Shunt StorageLocationSLC-disable2.wmf+–+–– + – +SLC In Relay ConnectionsSLC-fmC1.wmfCRF-300-6SLC OutFigure 7.3 CRF-300-6 Wiring Connections
