The Model 100A kit is shipped with the following components:
- One automated ceiling register
- One 25’ modular register cable (black)
- One 7’ modular register drop cable (black)
- One modular T connector (3 port)
- Two register mounting screws
- One automated register installation guide

The Model 100A kit provides a single automated register add-on to an installed Model 101A or 102A system. Any number of Model 100A kits (maximum of 30) can be added to an installed Model 101A or 102A system. All the mounting hardware, cables and connectors needed to add an additional register is included in the kit. Two telephone type jacks are provided on each automated register, one labeled NO and the other labeled
NC. If the 7’ modular drop cable is plugged into the NO jack, the register will automatically go to the OPEN
position when the Model 101A or 102A master switch is set to the OFF position. If the7’ register drop cable
is plugged into the NC jack, the register will automatically go the complementary CLOSED position. In this manner, air flow can easily be proportioned between two areas of a home (or a single zone) by use of a simple on/off wall switch.
