What is the EST3 fire protection system?
Date: 2025-12-01Read: 7
The EST3 fire protection system is a top-level fire alarm control platform that represents high reliability, flexibility, and intelligence. It is widely used in places with extremely high safety requirements and is a classic product in the fire protection industry.
EST3 is not a single device, but a complete fire alarm control platform. It is usually installed in the fire control center of buildings such as office buildings, airports, hospitals, factories, large shopping malls, etc., serving as the "brain" of the entire fire protection system.
Intelligence: refers to its ability to communicate bidirectionally with each connected device, such as smoke detectors, manual alarm buttons, sound and light alarms, etc. It not only receives signals from devices (such as "detected smoke"), but also continuously monitors whether the device itself is working properly, such as whether the line is disconnected, whether the device is contaminated, etc.
Fire alarm control: Its core function is to receive fire warning signals, make logical judgments through internal programs, confirm the fire, activate corresponding fire-fighting equipment (such as alarm bells, smoke exhaust valves, fire broadcasting, gas fire extinguishing systems, etc.), and guide personnel evacuation.
A typical EST3 system includes:
1. Host/Controller: The core of a system, usually one or more chassis, with various functional cards (CPU card, power card, circuit card, etc.) inserted inside. It is responsible for processing all information and making decisions.
2. Detection equipment: such as smoke detectors, temperature detectors, composite detectors, etc., used to perceive fire characteristics.
3. Manual alarm device: a manual fire alarm button for personnel to manually trigger when a fire is detected.
4. Sound and light alarm equipment: fire alarm, sound and light alarm, fire emergency broadcast, etc., used to issue audio-visual alarms.
5. Input/output module: This is a critical component. They serve as a bridge between the controller and external devices.
6. Input module: Monitor the status of non intelligent devices, such as water flow indicators, pressure switches, etc.
7. Output module: controls external devices such as starting/stopping smoke exhaust fans, closing fire doors, releasing gas fire extinguishing agents, etc.
8. Loop: All smart devices (detectors, modules, etc.) are connected to the host through a bus (loop), greatly simplifying wiring. An EST3 host can support multiple circuits, each of which can connect hundreds of devices, making it ideal for large and complex buildings.
