Electrical fire monitoring equipment and the system of the alarm signal should be located in the fire control room or someone on duty. The host power supply should be taken from the control center of the fire supply (AC220V). Each monitor is powered by field power supply or controller.
1. Installation form of power distribution cabinet (box)

In general, the new project has a special floor distribution cabinet (box) on the floor, which can place the detection controller in the distribution cabinet (box) and install it on the guide rail as far as possible from the conductive busbar, and then install the residual current transformer In the power bus, fixed firmly, to detect the connection between the controller and the transformer should be shielded wire.

2. Installation of external form of distribution cabinet (box)

In the distribution cabinet (box) outside the installation of detection controller, whether it is on the new project or renovation project, are applicable. If there is a fire control box specially installed with the detection controller, it can be placed near the distribution cabinet (box) after loading the detection controller. Similarly, the residual current transformer installed in the power bus, fixed firmly, to detect the connection between the controller and the transformer should be used to set the scope of shielded wire. For the renovation project, because the transformer is closed, so in the installation, not only pay attention to construction safety should also try to avoid power off too long, affecting the user's electricity.

3. Power distribution cabinet (box) complete sets of installation design

If the switchboard (box) panel embedded in the detection controller, the residual current transformer is still firmly fixed in it, do not increase the fire monitoring box, do not want to change the distribution cabinet (box) internal structure, both beautiful and convenient Should be clearly made in the design requirements, by the parties in the construction drawings will be approved after approval, by the distribution cabinet (box) complete sets of manufacturers, fully consider the reserved panel embedded probe controller hole problem.
4. Installation wiring design and precautions

Products in the installation of wiring should take three precautions. Products should be implemented in accordance with the provisions of fire fighting. Each installation terminal, wiring shall not be reversed, the number shall not exceed 2. When installing the wiring, you must strictly distinguish between the N line and PE line, through the residual current transformer N line, not as a PE line, not repeated grounding or access equipment exposed to the conductor. PE lines must not pass through the residual current transformer. Second bus installation and routing, pay attention to the strength of the wires separated from the line, not allowed to cross and lap. It is forbidden to penetrate into the same metal tube with power lines, lighting lines, video lines, broadcast lines, telephone lines and so on. Wiring should be neat, the wire should be tied into a bundle, threading can be used flame retardant PVC pipe, metal pipe and metal trunking. In the pipe, trough, the nozzle should be blocked, slot. The communication line between the monitoring equipment and the detector shall be twisted pair, the recommended wire diameter shall not be less than 1.5mm2. When the system is used in strong interference place, the communication line shall be shielded twisted pair, shielded twisted pair shield should Good land.
