The fire equipment power monitoring system is an essential subsystem of the fire alarm and control system. The system realizes effective real-time monitoring and display of the working status, undervoltage alarm information and fault information of each fire power equipment and backup power equipment in the fire control room, ensuring the normal operation of fire equipment and safeguarding fire safety.
Chinese product manual from 海湾安全技术有限公司 (GST) for the GST-N series fire equipment power monitoring system. It describes a system built from fire equipment power status monitors and different voltage or voltage/current sensors, with sensor power and communication over a two-wire bus and optional CAN networking between monitors.
The manual covers the GST-DJ-N500 and GST-DJ-N900 monitors, the GST-DJ-D40C, GST-DJ-D44C, GST-DJ-S60C, GST-DJ-S63C and GST-DJ-S30C sensors, their functions and technical parameters, and system design, application and sensor setup. This manual is written in Chinese.
