AL201 Overfill Protection Device Weatherproof Alarm
Model AL201-1-TT-12VDC-HTR Weatherproof Alarm
The Model AL201-1-TT-12VDC-HTR is a weatherproof alarm panel that accepts a switch contact input and provides an audible alarm signal when the external contact is closed. The green pilot light indicates the 12 VDC 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 addition there is a timer circuit that silences the horn 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. 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). The panel is heated so it will work down to -40 deg. C.
