Cooper CAS381 Internal Intelligent Addressable Wall Sounder

The Cooper CAS381 Internal Intelligent Addressable Wall Sounder is an intelligent addressable internal wall sounder designed to deliver clear, high-decibel audible emergency warnings across commercial life safety systems. Manufactured by Eaton Cooper for seamless integration into addressable fire alarm loops, it draws both operating power and digital communications directly over the two-wire loop to simplify cabling and eliminate external power supply dependencies. The unit produces clear acoustic sound output up to 100 dB(A) to penetrate ambient background noise, offers soft-addressing capabilities for efficient commissioning, incorporates a built-in short-circuit loop isolator to preserve system communication integrity during line faults, features low current consumption to optimize loop device capacity, and is housed in a compact flame-retardant ABS red enclosure designed for indoor wall surface mounting.
