Description
Use
The optical alarm device SO-Ad1 is a universal outer signalling device with the following field of applications:
- widely meant optical signalling of the hazard,
- gate automation,
- signalling of the machine operation state.
Construction
The SO-Ad1 optical alarm device is made of non-flammable plastic material. The signalling device enables generation of three optical effects. As the light source there are used LED diodes. The signalling device has got three cables, you should connect the supply voltage to black and red conductors (black colour: ground, red colour: +24 V DC), the yellow conductor is a control conductor.
Control
| Connecting the yellow conductor |
Optical signal generated by the signalling device |
| Unconnected |
The signalling device operates as a “light bulb”. Connecting supply voltage switches the fixed light on, disconnecting switches the signalling device off. |
| +24 V DC |
Optical signal of irregular light (irregular frequency increases the signal visibility) |
| Supply ground |
