Master Alarm

Each signal contains a green LED indicator for normal and a red LED indicator for abnormal conditions. When a fault occurs, the green LED turns off and the red LED illuminates, and the audible alarm sounds. The red LED flashes until the front panel alarm mute button is pressed. After the alarm mute button is pressed, the red LED remains illuminated but does not flash. The red indicator automatically turns off and the green LED illuminates when the fault is corrected

The master alarm shall identify the last alarm condition by flashing, while the already acknowledged alarm shows a continuous red signal.

A repeat alarm function shall, when enabled, be capable of turning on the buzzer again, after a preset time, if the fault condition has not been rectified.

Each module shall handle 20 functions, and 2 modules  can be accommodated per standard box for a total of 40 functions.
