AL201 Overfill Protection Device Weatherproof Alarm
Part No.: AL201-1-R-24VAC Weatherproof Alarm

The Model AL201-1-R-24VAC 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 120 VAC power. A transformer provides 24VAC output to the switches. 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. The relay contact output changes state when the switch input closes. It must be mounted in a non-hazardous location. Use Ktech float switches for the alarm input contacts. The panel is ULC Type 4 rated (Equivalent to Nema 4).
