OS- 360A Siren
The OS-360A is a hardwired outdoor backup siren combining a loud acoustic sirenn with a flashing light. The high-powered flashing light helps to locate the active siren.
The OS-360 is equipped with a piezo-electric siren mainly suitable for urban areas with a high building density. If necessary another piezo-electric siren (ACM-OS360) can be used. 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’s housing is made of mechanical, weather and UV-resistant plastic. The circuit board is protected against air humidity by a double layer of varnish.
