6. Installation and Maintenance

Installation Requirements

• Environmental Requirements: The installation environment should maintain a constant temperature (0℃-55℃) and constant humidity (5%-95%), avoiding dust and corrosive gas erosion.
• Power Management: A stable power supply (usually DC 24V) must be ensured, and power fluctuations that cause system malfunctions should be avoided.

Maintenance Points

• Hot Swapping: This module supports hot-swap maintenance, allowing faulty modules to be replaced without shutting down the system, ensuring continuous operation of the system.
• Fault Diagnosis: Maintenance personnel need to be familiar with the fault codes and diagnosis process of the HIMA system. The system is usually equipped with a monitoring module (such as F7131) for real-time monitoring of the health status of the main control module (such as F7508).
• Computer Room Management: The maintenance manual emphasizes the airtightness of the computer room, temperature and humidity management, and personnel operation procedures to prevent the external environment from affecting the safety system.
