Some standard content:
GB17429—1998
As an important part of the automatic fire alarm system, the fire display panel is increasingly widely used in industrial and civil buildings, playing an important role in protecting people's lives and property. However, there is no unified technical standard for fire display panels in my country. Manufacturers often design and produce products according to user requirements or enterprise standards, resulting in different product performance and quality, which brings great difficulties to product quality supervision and inspection, and it is difficult to ensure the reliability of product quality and performance. For this reason, this standard is formulated to provide a technical basis for the production, inspection and quality supervision of such products.
This standard includes six parts: scope, reference standards, technical requirements, test methods, product classification, and marking. The setting of environmental test items and the provisions of test methods are all referred to the relevant provisions of GB16838--1997 "Environmental Test Methods and Severity Levels for Fire Electronic Products". This standard is a mandatory standard. After the implementation of this standard, fire display panels used in general industrial and civil buildings should be inspected according to this standard.
This standard is proposed by the Ministry of Public Security of the People's Republic of China. This standard is under the jurisdiction of the Sixth Sub-Technical Committee of the National Technical Committee for Fire Protection Standardization. This standard was drafted by the Shenyang Fire Science Research Institute of the Ministry of Public Security. The main drafters of this standard are: Song Xiwei, Wang Yan'e, Ding Hongjun, Guo Tienan, and Zhuang Binghua. 4.95

The output power is 5063 Grounding wire: The grounding wire of the DC power supply and the electrostatic discharge probe used in the electrostatic discharge test must be connected to the safety grounding wire or the grounding plate together with the grounding plate.
4.11 Radiated electromagnetic field test
4.11.1
GB 17429-1998
Test the adaptability of the fire display panel to work in the radiated electromagnetic field environment. 4.11.2 Requirements
4.11.2.1 During the test, the sample should not issue a fire alarm and an irreversible fault signal. 4.11.2.2 After the test, the performance of the sample should meet the requirements of Article 4.3.2. 4.11.3 Method
4.11.3.1 Place the sample on the insulating table and connect the sample to the fire alarm controller according to the requirements of the normal monitoring state. Turn on the power supply to put the sample in the normal monitoring state.
4.11.3.2 Connect the test equipment according to Figure 8, place the transmitting antenna in the middle, and place the sample and the electromagnetic interference meter 1m on both sides of the transmitting antenna.
4.11.3.3 Adjust the output of the 1MHz~1GHz power signal generator so that the reading of the electromagnetic interference meter is 10V/m. During the test, the frequency should change slowly at a rate not greater than 0.005 octave/s within the frequency range of 1MHz~1GHz. At the same time, the sample should be rotated, and the working conditions of the sample should be observed and recorded. If the transmitting antenna used is directional, the transmitting antenna should be aligned with the electromagnetic interference meter antenna first, and the output of the power signal generator should be adjusted to 10V/m; then the transmitting antenna position should be reversed and aligned with the sample for testing. Within the frequency range of 1MHz~1GHz, the test should be carried out with the horizontal polarization and vertical polarization of the antenna respectively. 4.11.3.4 During the test, monitor whether the sample sends out alarms and irreversible fault signals; after the test, the basic function test of the sample should be carried out according to the provisions of Article 4.3.
4.11.3.5 The test should be carried out in a shielded room. To avoid large measurement errors, the position of the antenna should meet the requirements of Figure 9.
