AL101 Overfill Protection Device, Indoor Alarm
Part No.: AL101-4-4R Indoor Alarm Panel

The Model AL101-4-4R is an Indoor alarm panel that accepts four switch contact inputs and provides an audible alarm signal when the external contacts are closed. It must be mounted in a non-hazardous location. The white pilot light indicates the 120 VAC power. The TEST push-button is a momentary button that turns on the four red lights and the horn. The red pilot lights provide the visual alarm indication for each alarm contact. The MUTE push-button is a momentary button that mutes the horn for the four alarm inputs. In the event of a power failure the alarm will come back on with the power. The red light remains on until the alarm condition is corrected. The alarm circuit resets automatically. The panel also has a relay dry contact output for each switch input. Use Ktech float switches for the alarm input contacts.
