Cooper CAS381 Internal Intelligent Addressable Wall Sounder

The Cooper (Eaton) CAS381 is a high-efficiency internal wall sounder that seamlessly integrates into Eaton’s intelligent addressable fire systems. Engineered for rapid installation, it features a “first-fix” back box and a simple clip-on assembly that reduces labor time. The device utilizes a sophisticated digital protocol that supports soft addressing, allowing the control panel to automatically assign its identity. It provides a powerful sound output of up to 100dB(A) while maintaining a low alarm current (typically less than 6mA), which maximizes the number of devices possible on a single loop. With four selectable tones and three volume levels adjustable directly from the control panel, the CAS381 offers flexible notification coverage. Technically, it includes an integral short-circuit isolator to protect loop integrity and is fully certified to EN54-3 and EN54-17 standards. Technical Specifications ? Brand: Cooper (Eaton) ?
