AL201 Overfill Protection Device Weatherproof Alarm
Part No.: AL201-9-9R-FS Weatherproof Fail-Safe Alarm Panel

The Model AL201-9-9R-FS is a weatherproof fail-safe alarm panel that accepts nine switch contact inputs and provides an audible alarm signal when the external contacts are opened. 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 nine 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 nine 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. The panel is ULC Type 4 rated (Equivalent to Nema 4). (NO / NC) normal refers to the shelf state of the relay.
