Product Description:

The GST DC-9105E Conventional Reflective Beam Smoke Detector is a reliable smoke detection solution designed for large open areas where traditional detectors might struggle. It is perfect for warehouses, atriums, shopping malls, airports, and industrial facilities. This device provides fire protection across wide spaces without needing multiple point detectors.

It operates on a 24V DC power supply and uses reflective infrared technology to precisely detect smoke particles. It covers distances from 5 to 100 meters and monitors areas up to 1400m², with a width of 14 meters. This makes it a cost-effective and efficient choice for high-ceiling and spacious environments.

The GST DC-9105E has a built-in microprocessor that allows for intelligent signal analysis. This helps the detector tell the difference between real fire events and potential false alarms from dust, lightning, or other environmental factors. The integrated laser alignment tool and digital signal strength indicator simplify installation and calibration. This reduces setup time and ensures accurate alignment.

For added reliability, the detector includes drift compensation, self-diagnostics, and adjustable sensitivity levels. These features help maintain consistent performance, lower maintenance needs, and ensure early smoke detection, even in tough industrial conditions.

Additionally, the GST DC-9105E supports standard N/O fire and N/C fault dry contact outputs. This makes it easy to integrate with standard fire alarm panels and broader fire safety systems. Its LPCB certification confirms compliance with international fire safety standards, giving building owners and facility managers peace of mind.

Built for long-lasting durability, intelligent operation, and excellent coverage, the GST DC-9105E Conventional Reflective Beam Smoke Detector is the trusted choice for protecting large facilities against fire hazards while providing efficient monitoring and reliable protection.
