Fire Lite 5351RBAUS-BL Intelligent Rate-of-Rise & Fixed Temperature Heat Sensor – Black Addressable Heat Detector

The Fire Lite 5351RBAUS-BL is an intelligent addressable heat sensor designed to provide reliable thermal fire detection in environments where smoke detection may not be suitable. Combining rate-of-rise sensing with a fixed temperature alarm threshold of 57°C (135°F), the detector offers fast response to rapidly developing fires while maintaining dependable protection in challenging environments.

Finished in black for applications requiring a discreet appearance, the 5351RBAUS-BL is ideal for theatres, auditoriums, heritage buildings, retail spaces, and architecturally designed interiors with dark ceilings. The detector communicates with compatible Fire Lite intelligent fire alarm control panels over the addressable signalling loop and features rotary address switches for simple device configuration.

Dual high-visibility LEDs provide 360° alarm indication, allowing activated detectors to be easily identified during alarm conditions. The detector is compatible with approved Fire Lite/System Sensor addressable detector bases, including the B501AUS series, providing flexible installation options for new and existing intelligent fire alarm systems.
