Dahua Uzbekistan » Fire alarm systems

Fire alarm systems

Dahua also offers fire alarm solutions that are designed to detect fires, alert people in a timely manner, and prevent the spread of fire. The main components and features of Dahua fire alarm systems include:

Smoke and Fire Detectors: Devices that detect smoke or high temperatures in a room and signal a possible fire. They can be optical, ionization, or heat detectors.

Fire Control Panels: Centralized devices that collect information from sensors and detectors, process it, and transmit alarms when a fire is detected. Fire panels can be integrated with warning and automatic fire extinguishing systems.

Alarm and Evacuation Systems: Audio systems that automatically or manually transmit voice messages and alarms to alert people to the need to evacuate.

Manual Fire Call Points (Panic Buttons): Devices that allow people to manually activate an alarm when a fire is detected.

Integration with CCTV systems: Dahua provides the ability to integrate fire alarms with CCTV, allowing you to quickly verify alarms by viewing video feeds from cameras in the area.

Automatic control of fire extinguishing systems: Fire alarm systems can be linked to water, foam or gas extinguishing systems to automatically initiate extinguishing when a fire is detected.

Dahua fire alarm solutions help ensure the safety of buildings and people by providing timely alerts and the ability to integrate with other security systems.
