Product Description:

The GST DI-9102E Intelligent Photoelectric Smoke Detector is a highly sensitive smoke detection device designed for quick and accurate fire detection in commercial, industrial, and institutional settings. It uses photoelectric smoke detection technology to identify visible smoke particles from slow-smouldering fires, often before flames appear. This early warning system helps protect lives, assets, and critical infrastructure.

The DI-9102E is powered by a smart microprocessor, which ensures reliability, continuous self-checks, and precise fire and fault analysis. Its electronically addressable design allows for easy integration with modern addressable fire alarm systems. This setup enables centralised monitoring, faster incident response, and real-time control. Fire safety teams can quickly find the source of an alarm, reducing response times and enhancing overall safety management.

Built for adaptability to different environments, the detector features drift compensation that automatically adjusts sensitivity based on changes in dust, humidity, or air quality. This significantly reduces false alarms. Its compact, low-profile design and 360° LED indicator provide clear visual status updates, making installation, inspection, and maintenance straightforward across various settings.

The DI-9102E is ideal for offices, hospitals, shopping malls, hotels, educational institutions, and industrial facilities. It combines state-of-the-art photoelectric smoke detection with strong performance. Its early warning capabilities not only ensure compliance with fire safety standards but also protect operations and valuable assets. With reliable smoke detection and easy integration into addressable fire alarm systems, the GST DI-9102E Intelligent Photoelectric Smoke Detector sets a new standard for proactive and effective fire protection in modern facilities.
