G SERIES USER MANUAL
5.0 INSTALLATION OF OPTIONAL ACCESSORIES
5.12 Dual EMS
Dual EMS G-Series systems are available for cases when:
•
There are LED loads with different operating voltages.
•
There is a need to operate different LED load at different settings (for example two different flash
patterns, intensities, or flash durations).
•
There are more LED loads to operate than can be accommodated with one EMS (this is rare, since one
EMS can drive up to 8 circular beacons or LED-enhanced signs or 4 RRFBs).
The second EMS is located on the left side of the cabinet and is programmed separately from the first EMS.
When different load types are used, each EMS will be pre-configured for the load type and color
indicated by the check marks on the label next to the User Interface. Ensure the connected
loads match the label of the EMS they are connected to.
If the EMS load labels are blank, check the settings to ensure the configuration is correct for the
loads used. Contact Carmanah for guidance.
Ensure both EMS units in a dual EMS G Series have radio communications enabled and are on
the same channel. This will ensure the second EMS responds to activation signals that are
applied to the first EMS.
Dual EMS units are always configured with wireless communication, which is how one EMS signals the other that
it has received a momentary or steady activation signal. Dual EMS systems cannot have an internal time switch
because the second EMS occupies the space inside the cabinet which the time switch would normally occupy.
