I've focused the DSC portion of the site around the popular DSC PC1616 control panel. Although my how-to's and wiring diagrams are made for the PC1616, they can also be used for the PC1832 and PC1864. The larger panels have a higher hardwire and wireless zone capacity, but their wiring schemes and programming methods are exactly the same.
Make sure to purchase a DSC kit that includes a keypad with an "RFK" suffix, these will have a built-in wireless receiver for wireless device capability. Unlike Honeywell panels, DSC panels can be programmed with any keypad, so a custom alpha display isn't absolutely necessary, but would still be a cool thing to have.
