1. Brief Introduction                                                     

1.1 Overview

The multifunctional power sensor ES210T,adopts advanced ultra-low power large-scale integrated circuit technology and high-tech products manufactured by SMT process. The key components are long-life components of international well-known brands to improve reliability and life of the product.The combined electric fire detector ES210T is composed of safety monitoring unit and metering unit with RS485 communication function. In the safety monitoring, the built-in current transformer is used to monitor the remaining current, and the built-in temperature sensor is used to monitor the wire temperature. The meter has the advantages of high measurement accuracy, good stability, strong overload capacity and high reliability, widely used for monitoring & measuring safety parameters .

1.2 multifunctional sensor Standards

Complied with standards:

GB14287.2-2014 electrical fire monitoring system-part 2: residual current electrical fire monitoring detector

GB14287.3-2014 electrical fire monitoring system part 3 Temperature-measuring electric fire detector

IEC 62052 - 11 - 2003 electric measuring instrument. General requirements, test and test conditions-part 11 measuring instruments

IEC 62052 - 21 - 2004 Electric quantity measuring equipment (AC) General requirements, tests and test conditions. Part 21: tariff and load control equipment

2. Fire Detector Basic Functions                                                         

2.1 Metering & Monitoring

The multifunctional power sensor can measure, record and display the remaining current, wire temperature and other safety parameters of the circuit of the current equipment, as well as the operating parameters such as power, voltage, current, power factor and so on.

2.2 LED & Backlight Indication

The multifunctional sensor manufacturer uses three bright & long-life LED indicators with the following backlight display panel functions:

-Relay indicator: red, which lights up only when the contacts of relay are closed .

-Pulse indicator: flashes when the device is running at the load end, flashes more frequently with the greater the total power of the device, and does not flash when there is no load.

-Backlight indicator: green, working properly; yellow, alarm event; red, alarm trip event
