AL201 Overfill Protection Device Weatherproof Alarm
Part No.: AL201-7-7TR-FS Weatherproof Alarm

The Model AL201-7-7TR-FS is a weatherproof fail safe alarm panel that accepts seven N.C. switch contact inputs and provides an audible alarm signal and a delayed open dry contact output when the external contacts are opened. The white pilot light indicates the 120 VAC power. The TEST push-button is a momentary button that turns on the seven red lights and the horn. The red pilot lights provide the visual alarm indication for each alarm contact. When the unit goes into alarm a delay on timer is started and the contact output will open in 15 minutes, there is one timer output for each alarm. The MUTE push-button is a momentary button that mutes the horn for the seven 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. 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).
