Product Description:

The GST DI-9103E Intelligent Heat Detector is a precise fire detection device that responds quickly and reliably to fire hazards in various environments. It uses both rate-of-rise and fixed temperature sensing to identify sudden temperature increases and sustained high heat levels. This ensures early detection and timely alerts to protect property and people.

With a smart microprocessor, the DI-9103E can accurately tell real fire events apart from harmless changes in the environment, which cuts down on false alarms and improves overall safety. This electronically addressable heat detector works well with addressable fire alarm control panels. This allows for centralised monitoring, easier maintenance, and straightforward system checks for facility managers and safety teams.

The DI-9103E is perfect for locations where smoke detectors do not work well, like commercial kitchens, mechanical rooms, warehouses, industrial plants, and areas with dust or humidity. By focusing on heat detection, this device offers a reliable solution where smoke sensors might not perform effectively, ensuring reliable fire protection.

Built to last, the DI-9103E has a sturdy, compact design and is LPCB-certified, meeting international fire safety standards. Its reliable performance, smart sensing, and easy integration with addressable systems make it a vital part of modern fire alarm setups, providing accurate alerts and peace of mind.

Whether used in industrial, commercial, or specialised settings, the GST DI-9103E Intelligent Heat Detector offers quick and reliable fire detection, lowers false alarms, and boosts overall safety. It is a crucial choice for any fire safety approach.
