The OS-350 is an outdoor non-backup siren combining a loud acoustic siren with a flashing light. The flashing light helps to locate the active siren. Optional piezo-electric siren (ACM-OS360).
The siren’s housing is made of mechanical, weather and UV resistant plastic. The electronic circuit board is protected against air humidity by double-layer varnish. The device is protected by two magnetic tamper switches. If higher security is demanded, we recommend using the OS-360 or the OS-365 backup outdoor siren.
