They differ from the fogging systems because of the visibility obstruction technology. Fogging systems produce fog by spraying the fluid into a heat exchanger; while smoke systems are pyrotechnical devices which generate smoke made of solid substances without any heater. Smoke systems do not need to be connected to 220 V or 110 V power supply to work correctly, so they are easy to install. They can be cable connected to the alarm central or wireless with battery model.
The smoke system is made of an external metallic cabinet and an electronic board that allows to control the arming and the shooting commands – through the alarm -, to program any delay in the shooting, to set up even more than one smoke system in the same area with running shots. Smoke systems, once activated, cannot be interrupted because they consume the whole cartridge with one shot; after that, it will be necessary to change the smoke cartridge. The emitted smoke has a moderate density, it’s characterized by a persistent smell and it leaves a light dust residual.
