OS-365A Outdoor Siren

The OS-365A is equipped with a magneto-dynamic siren that is mainly suitable for single-family homes or buildings with more space around them. Two tamper switches are built into the unit. They react to removing the cover from the unit or removing the siren from the wall. The siren housing is made of plastic resistant to mechanical, weather and UV radiation. The board is protected from moisture in the air by a double layer of varnish.
