The Eaton Cooper CAS381WP is an IP66-rated weatherproof intelligent addressable wall sounder for Eaton intelligent addressable fire alarm systems. It suits external and wash-down areas.
The sounder is loop powered and soft addressed, has a built-in short-circuit isolator, and its tone and volume are set from the fire control panel, so there is no need to access the sounder to change them. An internal version (CAS381) is also available.
