System Sensor 2351TB Photoelectric and Thermal Smoke Detector White

System Sensor 2351TB Intelligent Photoelectric and Thermal Smoke Detector – White

The System Sensor 2351TB is an intelligent multi-sensor smoke detector that combines advanced photoelectric smoke detection with a built-in 135°F (57.2°C) fixed temperature heat detector for enhanced fire protection. Designed for use with compatible addressable fire alarm systems, the detector provides fast, reliable detection of both visible smoke and elevated temperatures to improve life safety and reduce nuisance alarms.

Using addressable analog communication, the 2351TB continuously transmits an analog representation of smoke density to the Fire Alarm Control Panel (FACP), allowing the system to make intelligent decisions based on real-time environmental conditions. The integrated heat sensor also generates an alarm when the temperature reaches 135°F (57.2°C), in accordance with UL 521 requirements.

The detector features convenient rotary address switches for quick and accurate device addressing, making installation and commissioning simple and efficient.
