How To Sync: STL Z® Series TIR LED Surface Mount Warning Lights (Dual Memory)

[@D4S_PressureWashing]

I just purchased the z3 and z4. I misunderstood your video. I thought With the dual memory function, 1 memory should be able to do sync, and 1 memory should be able to do alt sync since each memory has a different wire.

Yes sir, that is correct. Program Mode/Power 1 in Sync then program Mode/Power 2 in Alt Sync and you should be able to swap between the two Sync/Alt Sync modes by activating the power cables independently.

Additionally, please note the Z3 will be able to Sync/Alt Sync with Z3 models. The Z4 will be able to Sync/Alt Sync with Z4 models. They will not Sync/Alt Sync together since they will have a different number of flash patterns.

​@SpeedTechLights I did try to program the z4 in Sync and alt sync for the two different modes. When I program the alt sync on the second mode (brown wire), once I return to the first mode(red wire) the both modes stay on alt sync. I called the 800 number to ask and the lady who answered said that you can't be in two different sync for two different modes. So can you clarify.

​@@D4S_PressureWashing Apologies, after further review, the Sync/Alt Sync modes will override both Power Mode 1/2. Now, you will still be able to program different patterns/speeds in Power Mode 1/2. To switch between Sync/Alt Sync you will use your White cables. To go from Sync to Alt Sync, hold White to power for 2-3 seconds. To go from Alt Sync to Sync, tap your White cables to power. This would be best if the White cables are hooked up to a momentary switch. Let us know if you have any other questions and we will be happy to help.
