Bosch FIRERAY 50RV Reflective Beam Smoke Detector

Bosch Fireray 50 RV

The Bosch Fireray 50 RV is a linear beam smoke detector designed for reliable fire detection in large open spaces. It uses an infrared beam projected between a transmitter/receiver unit and a reflector to detect smoke by measuring signal attenuation.

This detector is ideal for environments where traditional point smoke detectors are impractical, such as warehouses, industrial facilities, atriums, and large halls.

Key Features

• Infrared beam smoke detection technology
• Detection range: 5 to 50 meters
• Transmitter, receiver, and processing unit integrated in one housing
• Automatic alignment assistance and calibration
• Adjustable alarm thresholds (approx. 25%, 35%, 50%)
• Automatic contamination compensation (AGC)
• LED indicators for alarm, fault, and status
• Auto-reset or latching alarm modes
• Fault detection (beam interruption, misalignment, contamination)

Technical Specifications

• Model: Fireray 50 RV
• Type: Linear beam smoke detector
• Detection Principle: Infrared beam obscuration
• Operating Range: 5 – 50 m
