Xantech Six Zone Connecting Block/Expander

Add 6 zones to the 4 Zone Connecting Block above with this expander. It adds 2 jacks per zone (no additional common jacks are provided, use the common jacks from the 4 zone connecting block). Additional expanders can be added to increase the number of zones in multiples of 6. Please note that noise considerations may limit the maximum number of zones that can be added. (Each IR sensor picks up a small amount of stray IR noise present in the room and when many units are combined the common outputs may start to generate excessive noise) Generally no more than 12 sensors and 17 keypads should be combined in a system.
