Use:
The SAO-Wd2 acoustic-optical signalling device is intended for use to generate acoustic and optical signals in burglary alarm systems. SAO-Wd2 signalling device can also be used in technical systems. The signalling device is intended for use inside buildings.
Construction:
The SAO-Wd2 acoustic-optical signalling device consists of two parts – the first is the actual signalling device in a plastic enclosure. It houses power supply connection terminals. A piezoceramic transducer is used as the source of sound. LED diodes are used as the source of light. The second part – socket is an element used for mounting the alarm to a wall or ceiling with two wall plugs.
Installation:
For installation on the wall or machine/equipment housing. Only use the original holes in the enclosure for installation.
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.
