Product Description P/N: PBR-1191
Description
The Siemens PBR-1191 is a conventional linear beam smoke detector with a retroreflecting prism designed to ensure reliable smoke detection in open and high-ceiling environments. Its prism structure reflects incident light beams back along their path, providing consistent performance in beam detection systems. The device connects to a 24V supply and incorporates a reflector heater for reliable operation in areas prone to condensation.

Information About PBR-1191
The PBR-1191 is part of Siemens’ fire safety product line and is specifically engineered for use with beam smoke detection systems. It features a prism reflector with lateral faces formed by isosceles orthogonal triangles, ensuring precise double reflection of incoming light beams. The reflector housing is identical to the detector base, allowing straightforward installation and system integration. With its built-in heater option, the PBR-1191 maintains accuracy and functionality even in challenging environments with high humidity or condensation risks.
Key Features:
- Retroreflecting prism design: Returns light beams back along their path for accurate smoke detection.
- Isosceles orthogonal structure: Double reflection ensures consistent optical performance.
- Reflector housing: Built with the same base structure as the detector for simplified installation.
- Heater integration: Equipped with a 24V heater connection to prevent condensation interference.
- Durable construction: Designed to withstand structural vibration and movement.
- Wide application use: Suitable for open areas, warehouses, and high-ceiling facilities.
- Active system support: Functions as a core component of Siemens beam smoke detection systems.
The PBR-1191 delivers the reliability and precision required for effective beam smoke detection in demanding fire safety applications.
