The ActiveLine GH1 is designed to indicate various operating states of machines and systems. The possible signaling colours green, amber, red, blue and white are all shown in one single light element.

Each colour can be preset to continuous light, blinking light or strobe light.

The light is generated by use of light-emitting diodes. The model with sounder can also generate a penetrating signaling tone, with four adjustable sound levels.

The plastic housing, the foot and the sounder housing are made of impact-resistant thermoplastic. The cap consists of impact-resistant polycarbonate and the standpipe is made of aluminum.
