What are the control conditions and characteristics of fan linkage control of SF6 leak monitoring system?

Automatic start of abnormal indoor status: If the sub-zone control function is not defined, the system will automatically start the fan if the SF6 concentration or oxygen level alarm of any indoor detection unit is generated. The duration of continuous ventilation is the set time for continued ventilation until SF6 and oxygen are restored to normal.
2) 24 period timing control start: The interface or upper computer software will prompt the latest fan start and stop time.
(1) A total of 24 time segments are controlled from 00-23, the longest ventilation time that can be defined is 23 hours and 59 minutes (then the period is defined, and other periods are invalid), and the shortest ventilation time that can be defined is 1 minute.
If multiple periods are defined, the timing function needs to be cancelled. If period 00 can be cleared to zero, the timing of the subsequent 23 periods becomes invalid. Similarly, zeroing out any of these periods invalidates all subsequent period definitions. Users do not have to clear zeros individually.
3) Manual forced start: "EN." is the only key on the keyboard that cannot open the menu item because it is a forced ventilation key.
4) Define the sub-area control function: The detection unit numbers defined in the same area must be continuous.
5) No matter what the above conditions trigger the fan operation, the current fan operation status is displayed on the host interface or the upper computer interface.
