• 8 Zone bus expansion module (max 6 per system)
• Expansion plug in module for zones 17 to 64
• Requires expander module 9 - 16
• 8 Wired EOL EndOfLine

Should the need arise for the panel to have more than 16 zones, this is easily accomplished by adding an X64 unpowered expander - either inside the original metal enclosure, or set up as a remote installation in a separate location. Each unpowered expander provides an extra 8 zones, and since a total of 6 of these expansion modules may be connected to a single X64 panel, this means that along with the 16 potential onboard zones, the X64 provides 64 zones when all modules are utilised.
