The 4030 Slave Unit is a terrific little electronic device that can fire a flash when it "sees" another flash unit go off. Any number of slaves can be used to fire an unlimited number of flash units. Just plug the Slave into any Sync Outlet on our power packs.
The Slave can also be used on older M200 or M400 Monolights (all other Novatron Monolights come factory equipped with internal slave triggers).
Since the trigger is polarized it may be necessary to reverse the plug in some units if they don't fire.
CAUTION!!!! Never attempt to plug this device into any electrical wall outlet or extension cord. Doing so will result in the destruction of the Slave Trigger and will create a fire and electrical shock hazard!
