With the warning module WZ1, a warning phase can be implemented with any time switch for lighting. Its simple, parallel installation permits low-cost upgrading of existing lighting systems.
If the WZ1 is combined with a pulse switch of the ZS series, a mode switch can be used to determine whether the warning phase is to be activated only when the preset time elapses (in order to suppress it if the light is switched off manually) or is to be activated each time the light is switched off.
