AL101 Overfill Protection Device, Indoor Alarm
Part No.: AL101-1-R-SL Indoor Single Alarm Panel

The Model AL101-1-R-SL is an Indoor alarm panel that accepts a switch contact input and provides an audible alarm signal/strobe light when the external contact is closed. A red lighted push-button provides the visual alarm indication. The push-button is a momentary switch that, when pressed, mutes the buzzer/strobe light. In the event of a power failure the alarm/strobe light will come back on with the power. The red light remains on until the alarm condition is corrected. A relay contact output is available for the input switch. The alarm circuit resets automatically. It must be mounted in a non-hazardous location. Use Ktech float switches for the alarm input contacts.
