Xi'an System Sensor Electronics Limited company's electrical fire monitoring system is SSDH-J610 electrical fire monitoring equipment, SSDH-S612 residual currentelectric fire monitoring detector, SSDH-C615 heat electric fire monitoring detector and the terminal detector. This system uses magnetic current field effect and temperature effect of the electrical current lines and temperature changes transmitted to the monitoring equipment, when current or the temperature sudden change, the detector carries on the analysis to the change peak-to-peak value and compares with the warning setting value, and then transmission alarm signals and warning address to the monitoring equipment. Fire warning function: After the monitoring equipment receives the fire alarm signals which detector transmits, the monitoring equipment will be issued to a fire alarm signal sound and light, while liquid crystal display and the first follow-up warning alarm detector address, sensor type, alarm type, alarm value, and takes down the first alarm time.
Malfunction alert function: When the sensors detect the loss of equipment or detectors and monitoring equipment to connect a short circuit or open circuit failure. Monitoring equipment will be issued voice alarm and alarm indicator light will be light. At the same time in the LCD display the total number of failures, the address of the first alarm as well as the address of the follow-up alarm.
Linkage output function: After the monitoring equipment receives the fire alarm, if monitoring equipment's control selection switch is in “automatically” the position, monitoring equipment automatic start 8 groups of relays, if monitoring equipment's control selection switch is in
“manual” the position, the user may through the facial mask on operation key manual start, stop 8 groups of relays.
Network joint function: The system brings a group RS232 connection, may carry on the information with the superior machine(PC)to be interactive, centralized control bench demonstration.Event logging function: Monitors 256 events which the main engine might record occurred recently, including events and so on fire warning, malfunction alert, replacement operation had the address, the time.
Printing function: Monitors the main engine to be possible to choose and match the Chinese character printer, the printer may print the warning event and the time, the breakdown event and the time, the replacement operates and has the time."
