The DSC PC5108 Zone Expander is used to add additional hardwired zones to your existing control panel.  Each expander module has jumper settings that can be set for the desired zone numbers.  For example, if you are using an expander to add zones 9 through 16, you would make sure that jumper 1 is off, jumper 2 is on, and jumper 3 is on. If using any wireless devices on your system, be sure not to include any wireless zone on a module that has been designated for hardwire devices.  The zone sets would be: Zones 1-8 (main panel), 9-16, 17-24, and 25-32... Zone expanders are easily installed and will connect directly to the same keybus terminals as the keypads (red, black, yellow, green).  You must also run a small wire from the "TAM" terminal on the expander module to the "Black" terminal, also on the expander module.  Failure to jump the "tam" to "black" will result in a General System Tamper.
