System Sensor 5351BAUS Intelligent Fixed Temperature Heat Sensor – Select Series Addressable Heat Detector
The System Sensor 5351BAUS is an intelligent programmable temperature sensor from the Select Series, designed to provide reliable fixed-temperature heat detection for compatible addressable fire alarm systems. Featuring Point ID capability, the detector uses rotary address switches to enable precise device identification and continuous status monitoring through the fire alarm control panel.
Using advanced thermistor sensing technology, the 5351BAUS provides 59°C (A2S Class) fixed-temperature thermal detection, making it suitable for environments where smoke detectors may not be appropriate due to dust, steam, fumes, or other airborne contaminants. Detector operation and monitoring are managed by the fire alarm control panel, providing efficient system supervision and maintenance.
The modern low-profile design is engineered for straightforward installation and servicing, while dual LEDs provide clear 360° visual indication of detector status and alarm conditions. The 5351BAUS is compatible with approved System Sensor addressable detector bases and integrates seamlessly into Select Series intelligent fire detection systems.
