HS-L8ZT/400 electric fire detectors Shu HS-L8ZT/400 zero sequence current protection

HS-L8ZT/400 electric fire detectors Product Overview System should be set at the following location: important low-voltage power distribution room outlet circuit; fire lighting sub-region into the line at the main distribution box, power distribution box into the line of the total; building material inside the auditorium, conference rooms and other crowded places distribution box into the line; dance halls, recreation halls and other places of entertainment distribution box into the line; underground mall (shops) distribution box into the line; student dormitories, kindergartens, older buildings and other places distribution box into the line; units to focus on places such as brick or wood structure distribution box into the line and so on. According to the actual situation of the project, determine the types of detectors mounted power supply, voltage, monitoring methods, the sensors need to bare live conductors within a safe distance, while the metal housing sensors require a safety ground wire, make sure the Power supply cut off to install the sensor, and does not affect the integrity of the line to be monitored, there is no increase in the contact line. Controlled ground detector is mounted repeated later, 'IN-C-s systems. Residual current electric fire detectors, mainly for power frequency 50Hz, rated voltage 400V distribution system, used to prevent the residual current, short circuit, overload, phase loss, low voltage, over-voltage electrical fire caused by other factors, supply line can be measured simultaneously various electrical parameters, such as residual current, three-phase current, phase voltage, active power, reactive power, etc., to achieve real-time monitoring for line status. HS-L8ZT/400 electrical fire monitoring detector performance characteristics 1, fault alarm when the current probe detects a current probe or current probe itself transmission line fault occurs, the corresponding channel LED is lit, and sends intermittent fault alarm sounds when After troubleshooting, fault alarm automatically removed. 2, fire alarm when the current threshold detector samples the value greater than or equal to the fire alarm threshold, the current probe is determined by identifying abnormal electrical equipment, fire may occur when the current detector alarm signal, alarm indicator light, alarm sound. 3, the network function current probe comes way RS485 interface with a network of monitoring equipment to communicate. 4, the self-test function fire alarm threshold setting: through the function keys on the front panel to set the probe corresponding fire alarm threshold setting range is from 50 to 900mA. Module address setting: through the function keys on the front panel to set the probe corresponding fire alarm threshold setting range is from 50 to 900mA. 5, mute function when the fire alarm or fault alarm threshold is used to eliminate the sound. 6, the reset function resets silencer lights and all alarm and fault signals. 7, the relay output function when the current detector sends a fire alarm signal, the output relay automatic action.
