Generally use two, but the series of low-voltage distribution and risk of large multi-site shall be equipped with third-level protection. First-class protection of electrical fire detectors should be set low in the low voltage distribution switchgear room output power of each branch line; the second level should be set at the next level of the distribution of electric power distribution cabinet (or the total sub-floor bins) power output of each branch line; third level should be set in the load distribution box on the input or output, according to the user capacity of the economy and only when the input set for each channel in a controlled points moncler online, while the output on the output of each branch is controlled to have a lot of points. Electrical fire monitoring equipment, set up a smart fire protection device leakage more than 8, or place an area greater than 1500m Ugg stiefel, it should be connected into the system, can be used as a single system or as a fire control subsystem into the distribution automation system ( hereinafter referred to as Monitoring system should be set the place was on duty. Alarm monitoring to ensure that the host information and fault information can be transmitted to the premise of the fire control room to monitor the host can be set in a protected area nearby. Monitor the output of the host alarm information and fault information (usually binary) can be connected to the fire alarm system, fire control room display unit focused on display; then set the fire alarm system software should match accordingly, so that the display of such information and fire alarm information and combustible gas alarm information display are apparently different. In most cases moncler kaufen, electrical fire monitoring and fire alarm system host host in the same room side by side moncler billig kaufen, it is not recommended combined display. Electrical fire monitoring installation settings should refer to the host controller to set the fire alarm requirements. The main power must be fire power. Set the electrical fire monitoring system, must involve the relevant equipment selection, design, procurement, integration, installation, and the laying of the communication network construction.
