 Siemens PBR-1191 Conventional Linear Beam Smoke Detector

The Siemens PBR-1191 Conventional Linear Beam Smoke Detector is engineered to provide reliable smoke detection over large open areas, such as warehouses, atriums, and industrial spaces. Utilizing a retroreflecting prism, it ensures consistent performance even in challenging environments.

Key Features

• Extended Detection Range: Monitors areas from 17 to 280 feet (5 to 100 meters), making it suitable for expansive spaces.

• Retroreflecting Prism Design: Features a pyramid-shaped prism with isosceles orthogonal triangles, reflecting light beams back along their path for precise detection.

• Integrated Reflector Heater: Equipped with a 24V heater to prevent condensation, ensuring reliable operation in humid environments.

• Conventional Operation: Connects to a 24V supply, compatible with conventional fire alarm systems.

• Durable Construction: Designed to withstand structural vibrations and movements, maintaining detection accuracy.

Applications

The PBR-1191 is ideal for:

• Warehouses: Providing early smoke detection in large storage areas.

• Atriums: Ensuring safety in expansive open spaces.

• Industrial Facilities: Detecting smoke in environments with high ceilings and open layouts.

• Commercial Buildings: Supplementing or replacing point-type smoke detectors in large areas.
