GB/T 39673.3-2020Home and building electronic systems (HBES) and building automation and control systems (BACS) - Part 3: Electrical safety requirements (English PDF)

1 Scope

This part of GB/T 39673 specifies the electrical power of residential and building electronic systems (HBES) and building automation and control systems (BACS):

Gas safety requirements:

This section applies to electrical safety related to HBES/BACS networks, in addition to product safety standards for HBES/BACS equipment

Claim:

This section also applies to equipment that does not have a specific HBES/BACS product safety standard in the HBES/BACS network:

In addition, this section defines the device interface expected to be connected to an HBES/BACS network: This section does not apply to connecting to other

The interface of the network:

In addition, this section also determines the security requirements for the device interface expected to be connected to the HBES/BACS network: This section does not apply to

His network interface:

Note: An example of other networks is the dedicated ICT network covered by IEC 62949:

This section applies to:

---Operation station and other man-machine interface equipment;

---Management function equipment;

---Control equipment, automation stations and application-specific controllers;

---Field equipment and its interface;

--- Wiring and interconnection of equipment:

The above is used in a dedicated HBES/BACS network:

This section covers the following requirements and compliance criteria:

---Protect equipment from harm;

---Prevent network overvoltage;

---Contact current protection;

---Prevent the harm caused by different types of circuits;

---Protect communication lines from overheating due to excessive current:
