Carmanah G Series User Manual page 29

An LED Group can be used to wire one light bar, two circular beacons or two LED signs. Each LED Group has a
Bank 1 pair (positive and negative) and a Bank 2 pair. Alternating flash patterns cycle back and forth between
Bank 1 and Bank 2. If the flash pattern is set for unison and there are fixtures attached to both Bank 1 and Bank
2, both fixtures will flash in unison even though they are on different banks.
All four LED Groups are wired in parallel. That is, all B1+ are wired together, all B1− are wired together, and so
on.
The bottom four crimped terminals differ in appearance but there is no functional difference
between these fixture connection points and the others above.
Because of the parallel connections between the four LED Groups, when a given bank is
flashing, the current from the EMS LED driver will divide up among the fixtures attached to
that bank.
The LED terminal block label provides the colors of the fixture wires that are to be connected at each terminal:

Input/Output Terminal Block
The Input/Output terminal block is where input/output signal, switched control voltage, and unswitched supply
voltage connections are made. The top six positions on the Input/Output terminal block are always prewired to the
EMS by Carmanah. Position six and seven (DC−) are connected in parallel via a jumper. Position 8 is prewired
only when the optional DC Relay Kit is ordered.
