Cooper CAPT340 Intelligent Addressable Photo-Thermal Sensor

The Cooper (Eaton) CAPT340 is a sophisticated “dual” sensor designed for use with Eaton?s intelligent addressable fire systems, utilizing an integrated optical chamber and a precision thermistor. This hybrid approach allows the sensor to maintain the high sensitivity of an optical detector while using thermal data to filter out environmental nuisances, resulting in superior false alarm rejection. The unit features programmable day/night modes, where heat-only detection can be used during working hours in smoky environments and combined photo-thermal sensing can be active at night. Certified to EN54 parts 5, 7, and 17, the CAPT340 includes an integral short-circuit isolator, 360-degree LED visibility, and automated soft addressing, ensuring high system integrity and simplified installation for commercial and industrial facilities.

Dual-Mode Photo-Thermal Sensing Combines an optical smoke sensor with a heat element to detect everything from slow smoldering fires to fast clean-burning flames with high accuracy. ? Intelligent Soft Addressing Minimizes installation errors and saves time by allowing the control panel to automatically assign addresses to all loop devices without manual switch settings. ? Integral Short Circuit Isolator Enhances system reliability by ensuring that a single cable fault on the loop does not disable the entire detection line. ? Programmable Day/Night Modes Allows the sensor to be configured via software to use different sensitivity profiles (e.g., Heat Only or Multi-Sensor) depending on the building’s occupancy schedule. ? 360-Degree LED Indication Utilizes light-pipe technology to provide a high-visibility status LED that can be clearly seen from any angle in a fire or fault event. ? Drift Compensation Automatically adjusts the internal sensing thresholds to account for dust accumulation over time, extending the service life and maintaining consistent sensitivity.
