AL201 Overfill Protection Device Weatherproof Alarm
Model AL201-1-R-24VDC Weatherproof Alarm

The Model AL201-1-R-24VDC is a weatherproof alarm panel that accepts a switch contact input and provides an audible alarm signal when the external contact is closed. The white pilot light indicates the 24VDC power. The test toggle-switch is a momentary switch that turns on the red light and the horn when pushed up. The red pilot lights provide the visual alarm indication for the alarm contact. The mute toggle-switch is a momentary switch that mutes the horn for the alarm input when pushed down. 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. A relay contact output closes when the switch input opens. It must be mounted in a non-hazardous location. Use Ktech float switches for the alarm input contacts.
