AL201 Overfill Protection Device Weatherproof Alarm
Model AL201-1-R-TT-SL Weatherproof Alarm
The Model AL201-1-R-TT-SL is a weatherproof alarm panel that accepts a switch contact input and provides an audible alarm signal/ strobe light when the external contact is closed. The white pilot light indicates the 120 VAC power. The TEST toggle-switch is a momentary switch that turns on the red light and the horn/strobe light 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/strobe light for the alarm input when pushed down. In addition there is a timer circuit that silences the horn/strobe light automatically in 60 seconds. In the event of a power failure the alarm will come back on with the power for 60 seconds. 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.
