The vent relay basically works as a switch to activate the smoke machine. whatever smoke machine you use it'll have to work on its own, meaning it'll have to have its own battery. If you have one that is controlled by a push button switch you'd have to remove the switch and connect it to the relay. The relay can be adjusted for timing of how long or short you want the smoke machine to be on (timing it with the Pack lights).
