SIRIUS ACT is a modular system of command and signaling devices. The high IP69K protection means that SIRIUS ACT devices are insensitive to dust, oil, alkalis and extreme environmental influence. The innovative snap-on concept facilitates single-handed installation without special tools or having to hold the elements together. The flat, round metal and plastic elements combine functionality with a timeless, aesthetic design. Four design series and multiple ways of combining actuators and signaling devices, materials, color, front ring shape and illumination provide the optimum answer for every application, taste and budget.
