Application Fields
The NGP-3320 is a core component for integrated security management systems. Common applications include:
- Commercial Building Access Control
- Multi-site Corporate Security Networks
- Government and Educational Facilities
- Data Center Entry Management
- Real-time Alarm Monitoring and Event Logging
Product Instructions
- Mounting: Secure the NGP-3320 within a grounded metal enclosure. Use the provided standoffs to ensure the board does not touch the metal surface, preventing electrical shorts.
- Network Connection: Plug an RJ-45 Ethernet cable into the onboard LAN port for primary communication with the TruPortal software. Ensure the static IP address is configured via the web interface.
- Peripheral Wiring: Connect card readers to the reader ports using shielded twisted-pair cabling. Assign door strikes or magnetic locks to the onboard relays, ensuring appropriate surge suppression (diodes) is used.
- Testing: Once powered, verify the heartbeat LED is flashing. Use the system diagnostic tool to test reader inputs and relay triggers before finalizing the installation.

Product Q&A
Q: Is the NGP-3320 compatible with modern TruPortal software? A: Yes, it is designed to work seamlessly within the TruPortal ecosystem, serving as an intelligent gateway for door control and security monitoring.
Q: How many doors can a single NGP-3320 control? A: Out of the box, it typically manages 2 readers (one or two doors depending on configuration). However, its capacity can be increased through the use of downstream expansion modules connected via the RS-485 bus.
Q: What happens to access logs if the network connection is lost? A: The NGP-3320 features onboard non-volatile memory that stores thousands of events and user credentials. It will continue to grant access based on local logic and upload cached events once communication is restored.
Q: Can this board be used for fire alarm integration? A: Yes, the supervised inputs can be configured to monitor fire alarm triggers, allowing the controller to automatically release all fail-safe locks in an emergency situation.
