The Cooper (Eaton) CAH330 is a high-precision addressable heat detector that can be programmed to operate in multiple modes, including rate-of-rise or fixed temperature settings. Part of the Eaton intelligent addressable range, it communicates via a sophisticated digital protocol to provide rapid and accurate fire alerts while maintaining high immunity to environmental nuisances. The sensor features an integrated short-circuit isolator to protect the loop and utilizes soft-addressing technology to eliminate manual DIL switch configuration during installation. With its 360-degree LED visibility, slim-line profile, and EN54-5/EN54-17 certification, the CAH330 is an ideal solution for kitchens, boiler rooms, and industrial workshops where standard smoke detection would trigger frequent false alarms. Technical Specifications ? Brand Cooper (Eaton) ? Product Model CAH330 ? Part Number 400003FIRE-0003X ? Operating Voltage 18V to 30V DC ? Standby Current 220 ?A (Maximum) ? Alarm Current 5 mA (Maximum) ? Heat Class Settings A1R (Rate-of-Rise), BS (77?C Fixed), CS (92?C Fixed) ? Addressing Mode Auto-Addressing (Soft Addressed) ? Operating Temperature -10?C to 50?C ? Dimensions 104mm Diameter x 45mm Height (Excluding base) ? Weight 76 grams Key Features ? Selectable Thermal Modes Can be field-programmed via the control panel to operate as a Rate-of-Rise sensor (Class A1R) or a High-Temperature Fixed sensor (Class BS/CS) to suit specific fire risks. ? Intelligent Soft Addressing Simplifies commissioning by allowing the panel to automatically assign a digital address to the device, reducing labor costs and potential wiring errors. ? Integrated Short Circuit Isolator Safeguards the entire detection loop by automatically isolating a section if a short circuit occurs, ensuring all other devices remain operational. ? 360-Degree Status LED Features a high-visibility LED light pipe that ensures the alarm status is visible from any angle, facilitating rapid identification of the fire source. ? Slim-Line Design Boasts a low-profile aesthetic that blends unobtrusively into modern interiors while maintaining easy access for routine testing and maintenance. ? Robust Environmental Immunity Specifically engineered to provide reliable fire detection in “dirty” environments where smoke, steam, or exhaust fumes are part of normal operations.
