How the Liquid Level Alarm System Works
The system is powered by 120VAC or 240VAC with required conduit connections
Green LEDs illuminate to indicate power status
When a float switch or sensor activates, the alarm triggers:
Red LEDs flash
Buzzer sounds with pulse tone
Auxiliary contacts activate
Alarm remains active until the sensor resets
Press and hold the test/silence button to mute the buzzer while LEDs remain active
The system automatically resets once conditions return to normal
Low battery conditions are indicated by pulsing LEDs and buzzer signals, ensuring you’re always aware of system status
