This solution utilizes the Beilai Technology BA190 BACnet/IP Edge I/O module as a critical integration hub, bridging the gap between traditional professional access control systems and modern Building Automation Systems (BMS). It enables real-time data acquisition, local logical judgment, and seamless protocol conversion of key security statuses—such as door contacts, forced entry alarms, and fire alarm linkages. By converting decentralized, non-intelligent access point signals into standard BACnet/IP objects, the BA190 uploads actionable data to the Security Management Platform. This significantly enhances the centralization, automation, and incident response speed of the overall facility management.
The solution operates through a multi-layer architecture designed for reliability and speed:
Perception Layer (Sensors): Includes door contact sensors, exit buttons, glass break detectors, panic buttons, and dry contact alarm outputs from legacy access control panels.
Control Core (Edge Computing): The BA190 main module paired with compatible Y-series I/O expansion modules serves as the intelligent edge controller.
Execution Layer (Action): Controls sound and light alarms (strobes/sirens) and triggers alarm relays for immediate video surveillance recording linkage.
Management Layer (Integration): Integrates seamlessly with the BMS or central security platform via the BACnet/IP protocol, ensuring universal interoperability.
Operational Workflow:
Status Collection: The BA190 monitors the precise status of distributed devices (e.g., door open/closed, lock status) in real-time via high-speed digital input modules.
Edge Logical Judgment: Leveraging built-in edge logic, the module performs autonomous judgments without relying solely on the server. For example, it triggers a "Door Forced Open" alarm if a door contact breaks without a valid card swipe, or a "Door Ajar" alert if a door remains open beyond a preset duration.
Alarm & Linkage: Upon detecting anomalies, the BA190 immediately drives local sound/light alarms via digital outputs and sends dry contact signals to the CCTV system to tag video footage.
Data Upload: All events—status changes, alarms, and device faults—are mapped to standard BACnet objects and uploaded to the monitoring center for visualization on the graphical user interface.
The core of effective security monitoring lies in the precise acquisition and output of signals. We recommend the following configuration based on typical deployment needs:
Application: Monitoring door contacts, passive infrared sensors, and tamper switches.
Advantage: The Y13 features dry contact inputs with high noise immunity and compatibility. It requires no polarity distinction, allowing it to interface directly with 99% of security sensors. A single module can monitor 8 independent points, making it cost-effective for multi-door clusters.
2. Digital Output – For Local Alarming & Linkage Control Recommended: Y24 Module (4-Channel Relay Output)
Application: Triggering local sirens, strobes, or interacting with third-party elevator/HVAC controllers during emergencies.
Advantage: The relay outputs provide excellent electrical isolation and strong load capacity (Max. 250VAC/30VDC, 2A). They can directly drive AC 220V alarm devices without the need for intermediate relays, simplifying wiring complexity and reducing failure points.
3. Analog Input – For Extended Monitoring (Optional) Recommended: Y33 Module (4-Channel 0-5V/0-10V Analog Input)
Application: Advanced environmental monitoring, such as integrating Very Early Warning Smoke Detection apparatus.
Advantage: Captures precise 0-10V analog signals (e.g., air duct pressure or smoke density levels) to provide auxiliary data for comprehensive security status assessment.
Seamless Integration: Breaks down information silos by converting proprietary security signals into open BACnet/IP data.
Edge Intelligence: Built-in logic ensures faster local response (linkage) and reliability, even if network communication to the server is temporarily interrupted.
Flexible & Scalable: The modular design allows for easy expansion, simplifying the system architecture and reducing cabling costs.
Industrial-Grade Quality: Designed for harsh environments, ensuring stable 24/7 operation critical for security applications.
Convenient Maintenance: Features remote management capabilities for easier firmware updates and status checks.
The Beilai Technology BA190 BACnet/IP Edge I/O module delivers a highly flexible and robust "status monitoring and integration" solution for modern buildings. By effectively bridging the gap between professional access control systems and Building Automation Systems, it empowers facility managers with a holistic view of their security posture. Through edge intelligence and open standard protocols, the BA190 ensures that security management is not only centralized and visualized but also responsive and reliable.
