EM721FA Combined Electric Fire Monitoring Detector
EM721FA electric fire monitoring detector monitors the residual current in the system or branch through the external residual current transformer, and monitors the cable temperature or the environmental temperature in the box through the external temperature sensor. When the monitoring value is higher than the alarm setting value, the device immediately generates the alarm signal and uploads it to the monitoring equipment through the fire fighting bus 2. EM721FA adopts embedded hardware design architecture, with low power consumption, high intelligence, high reliability, Chinese large screen human-machine interface, easy operation and query parameters. In the process of operation, real-time self-inspection of internal core components can be carried out to ensure reliable operation. An EM721FA electrical fire monitoring detector can simultaneously measure multiple residual currents and temperatures.
EM721FA Electrical Fire Monitoring Detector is suitable for business complexes, high-end communities, schools, hotels, industrial plants and other personnel-intensive occasions, especially for distribution cabinets or distribution boxes with multiple feeders.
■ Monitoring function: 10 channels residual current and 1 channel temperature can be measured
■ Statistical function: Statistical alarm information and fault information, forming SOE records; Recording important operations such as reset and muffling, forming operation records
■ Communication function: remote transmission of information in digital form through intelligent communication bus, with high anti-jamming capability
■ Fault/Alarm Function: Acousto-optic Alarm
■ Alarm output function: relay output
■ Other functions: Chinese LCD display, setting and inquiring parameters; self-checking important components; storage of 64 alarm and fault records, power failure can be saved for 10 years.
