Fire mainframe display pressure switch regulation is going on
You want to see which information it shows in the status bar, if the (feedback) information (or regulatory) column, it means that the pressure switch action, and if it is in the fault column, it means that the pressure switch monitoring module is faulty (Or the signal bus is a problem or the module and the pressure switch connected to the line fault or the pressure switch connected to monitor the line state of the resistance of the poor contact, or failure of the module itself, etc. reported failure.
In the actual working environment, sometimes false, such as connecting the pressure switch line short circuit can trigger the input signal. So it is best to check whether the pressure switch action, if there is no action to check whether the line short circuit phenomenon.
The pressure switch is monitored by the monitoring module to monitor whether the pressure switch is active. If the pressure switch is activated, the monitoring module will be subject to the input signal, and the supervisory event will be displayed on the host. This is only the working principle
