SAO-Wd3 acoustic-optical signalling device

Intended use:

General purpose signalling dvice for use in automatic control systems, burglary alarm systems, technical systems. Compact design enables application in limited space locations.


Construction:

The SAO-Wd3 signalling device is placed inside a plastic enclosure. RGB power LED is used as the source of light. A piezoelectric transducer is used as the source of sound. The application of an optical system provides for uniform light intensity on the entire surface of the light bowl.

SAO-Wd3 is signalling device for use in general purpose industrial automatic control systems, in a sturdy white plastic enclosure. Adapted for direct power supply with the voltage from 10 V to 30 V. The device is capable of generating optical signals in 3 different colours (RYG) and acoustic signals matching the colours. The optical signals can be generated in flashes with the frequency of 1 Hz or continuous light. Due to the application of an RGB power LED, the device is compact and has a wide range of possible applications. The loudness of the acoustic signal exceeds 80 dB. There is also a possibility of muting the signalling device.


Installation:

The SAO-Wd3 signalling device can be installed on the wall or ceiling, it is recommended to use the original holes in the base of the device.


Opening:

To open the signalling device: screw out the screw locking the base, turn the shade anticlockwise while holding the base, then separate the shade and the base.

Closing:

To close the signalling device: fit together the markers. After that put together the device and turn in the direction marked with an arrow (the sequence in the drawing). On closing, lock the base by screwing in the locking screw.

Connection diagram:

Connecting power supply to appropriate terminals will trigger the acoustic and optical signals at the same time. Each light colour has a corresponding acoustic signal pattern. The optical signal can be generated in flashes with the frequency of 1 Hz or continuous light. Continuous light can be obtained by connecting the LC input to ground. Sound can be blocked by connecting the MT input to ground.
