Button for manual control, one key lock, one mute button, one light check button, and two communication status indicator lights:
● Manual control button: Press the button to send a command to start or stop the control device to the multi line control circuit card,
Start a 10 second timer; If the device corresponding to the button is in a fault state, no command will be sent;
● LED start status light: Upon receiving an event from the multi line control circuit card to control the device, the start light will illuminate; 10 seconds
Internally, if there is no regulatory device event, the startup light will flash until the regulatory device event is received, and the startup light will remain on;
LED feedback status light: Upon receiving a monitoring device event from a multi line control circuit card, the feedback light will turn on or off;
● Keylock: used to allow or disable the function of 32 manual control buttons on the panel;
Mute: When the communication between the multi line control circuit card and the CPU fails, the buzzer will sound at 2Hz. At this point, after pressing the [Mute] button, the buzzer stops sounding. At the same time, clear the startup status and fault status;
● Lamp inspection: Press the 【 Lamp Inspection 】 button, and 66 LED lights will flash alternately in 1HZ. At the same time, the buzzer beeps continuously;
