3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 26875.1 apply.
4 Classification
User information transmission devices (hereinafter referred to as "transmission devices") are classified by function into:
a) General purpose type (with information machine display and query control functions);
b) Gateway type (without information machine display and query control functions).
5 Technical Requirements
5.1 Appearance
The surface of the transmission device shall be free from corrosion, coating peeling, and blistering, with no obvious scratches, cracks, burrs, or other mechanical damage. Fastened parts shall not be loose.
5.2 Main Components (Parts)
5.2.1 Basic Requirements
5.2.1.1 The main components of the transmission device shall be finalized products that comply with relevant national standards.
5.2.1.2 The main power supply of the transmission device shall be a 220 V, 50 Hz AC power supply or a DC power supply with a voltage of 48 V or less.
5.2.1.3 The main power supply of the transmission device shall have overcurrent protection measures.
5.2.1.4 The positive connecting wire for the standby power supply of the transmission device shall be red, and the negative connecting wire shall be black or blue.
5.2.2 Indicators (Lights)
5.2.2.1 The transmission device shall have a green power indicator, a green operation indicator, a green communication indicator, and a yellow general fault indicator. Indicators (lights) shall be labeled with their functions in Chinese. The general purpose type transmission device shall also have a yellow query indicator and a red manual alarm indicator.
5.2.2.2 When powered by the main power supply, the power indicator shall be steadily lit; when powered by the standby power supply, the power indicator shall flash.
5.2.2.3 During normal operation of the transmission device, the operation indicator shall flash.
5.2.2.4 When the transmission device is transmitting data, the communication indicator shall be steadily lit; when data transmission is not occurring, the communication indicator shall remain off.
5.2.2.5 In the normal state of the transmission device, the general fault indicator shall be off; when any fault occurs, the general fault indicator shall flash.
5.2.2.6 Under ambient illumination not exceeding 500 lx, when lit, the indicators (lights) shall be clearly visible from a distance of 3 m directly in front, within a viewing angle of 22.5°.
5.2.3 Display Screen (Unit)
When in a display state, under ambient illumination not exceeding 500 lx, the displayed information shall be clearly readable from a distance of 0.8 m directly in front, within a viewing angle of 22.5°.
5.2.4 Sounder
5.2.4.1 Under rated operating voltage, the sound pressure level (A-weighted) of the sounder measured at 1 m directly in front of the transmission device shall not be less than 65 dB and shall not exceed 105 dB.
5.2.4.2 The sounder shall operate normally when the transmission device is powered at 85% of its rated operating voltage.
5.2.5 Fuses
For fuses or other overcurrent protection devices used in power supply circuits, their rated current value shall not exceed twice the maximum operating current. The parameter value shall be clearly marked near the fuse or other overcurrent protection device.
5.2.6 Terminals
Each terminal shall be clearly and durably marked with a number or symbol, and the corresponding use shall be explained in the relevant documentation. The power input shall be provided with independent terminals, and the terminals shall be equipped with protective measures against hand contact. Transmission devices powered by AC supply shall be provided with a protective earth terminal.
