Description
Use
The SO-Ad2 optical alarm device is used in industrial automation and event signaling systems.
Construction
SO-Ad2 optical alarm device has got the casing made of non-flammable plastic material, in which there are electronic components. In the top part of the casing there is the light source – LED RGB diode. Signalling devices of SO-Ad2 series have got in their cover: a supply terminal, a control terminal as well as a four-level microswitch, by means of which it is possible to choose duty cycle as well as frequency of signaling device flashes.
The additional element of the casing is the socket enabling to direct mounting of the signaling device to the ceiling or wall by means of two screws and wall plugs.
Operating design
SO-Ad2 is an optical alarm device, which enables optical signal generation of seven colours. The colour of generated signal is dependent on the supply input state of the signaling device. According to the principle of mixing colours R, G, B, through appropriate control of inputs the user receives colours consistent.
| Supply input |
| + R |
Supply input controlling the component R of the colour |
| + G |
Supply input controlling the component G of the colour |
| + B |
Supply input controlling the component B of the colour |
| GND |
Supply ground |
| Control inputs |
| LL |
Input controlling the reduction of light brightness (when connected to GND) |
| CL |
Input activating the fixed light (when connected to GND) |
Description of supply and control inputs
Opening
To open the alarm device you should: screw out the blocking screw, twist the shade to the left while holding the base, then move apart the shade and the base.
Closing
To close the alarm device adjust the markers, then assemble the device and twist it to the direction marked with an arrow (sequence shown in the drawing). After closing, screw in the blocking screw.

Control
The signalling device is activated through connecting the supply voltage to supply inputs controlling the colour components. The optical signal received in this method is ”mixed” digitally in order to receive appropriate colour proportions, what causes receiving the clear colour. Depending on the number of active inputs, the user receives the colour of warning signal consistent with the table below.

Through appropriate connecting of control signals, the user can receive the effect of pulsed light, fixed light as well as the light of reduced intensity. The frequency of pulsed optical signal can be included in the range from 0.5 Hz to 10 Hz. The next parameter, which can be established by the user, is the optical signal duty cycle. The duty cycle can come to 25% or 50%.
By means of the microswitch placed in the signalling device lid the user can change the frequency of pulsed light according to the table below.

When it’s necessary to change the duty cycle of optical signal from 25% to 50%, the user should switch over the first position of the microswitch (25% – ON, 50% – OFF).
