1.接线时，应按电气火灾监控探测器标明的电源进线端和出线端，正确接线，不得反接。
1. When wiring, the incoming and outgoing terminals of the power supply indicated by the electrical fire monitoring detector shall be correctly wired without reverse connection.
2.安装塑壳断路器时，应按要求，在电弧喷出方向有足够的飞弧距离。
2. When installing the molded case circuit breaker, there should be enough arc flying distance in the arc direction according to the requirements.
3.安装时，必须严格区分N线和PE线，3P四线式或4P四线式的N线应通过电气火灾监控系统的漏电互感探测器。通过电气火灾报警系统的漏电互感器的N线，不得作为PE线，不得重复接地或接设备外露可接近导体。PE线不得接入电气火灾监控保护装置。
3. During installation, n-wire and PE wire must be strictly distinguished. 3P four wire or 4P four wire n-wire shall pass through the leakage mutual inductance detector of electrical fire monitoring system. The N line of leakage transformer passing through the electrical fire alarm system shall not be used as PE line, and shall not be grounded repeatedly or the exposed accessible conductor of the grounding equipment. PE line shall not be connected to electrical fire monitoring and protection device.
4.电气火灾报警系统纳入配电系统施工单位施工时，双方应充分沟通，协调有关安装方式、尺寸和电气技术参数。新工程使用电电气火灾报警系统时，在配电柜(箱)订货时，应向厂家索取产品外形尺寸、开孔尺寸，以便于计算安装位置。
4. When the electrical fire alarm system is incorporated into the construction unit of the power distribution system, both parties shall fully communicate and coordinate relevant installation methods, dimensions and electrical technical parameters. When using the electric fire alarm system in the new project, when ordering the distribution cabinet (box), ask the manufacturer for the overall dimension and opening dimension of the product to facilitate the calculation of the installation position.
