The beaconsare industry-standard equipment and comply with MUTCD and ITE flash patterns, color, beam shape, andintensity. Beacon wiring is provided with a convenient terminal strip inside the signal head for easy wireconnection.LED loads driven from one EMS must have the same operating voltage. Do not mix differentsizes, colors, or types of LED loads connected to the same EMS. Use a dual-EMS G Seriessystem to drive two different LED loads.If powering three, five, or seven LED loads from a single EMS, use a “Unison” flash pattern toavoid current imbalance and ensure all loads receive the same amount of current while flashingand therefore produce the same brightness.All Carmanah traffic products use a constant-current LED output circuit. Not all traffic beaconsare compatible with this output. Please contact Carmanah for additional information and guidancewhen adding or replacing beacons or other hardware.When programming intensity for ITE-compliant circular beacons, minimum current settingsmust be applied (see Flash Pattern and Intensity in Section 6.1). Contact Carmanah for guidance.See Section 4.2 for information on installing circular beacons.
