ADJUSTABLE MOUNT

MODEL T-1S

EASY TO INSTALL. The liquid-tight 2" NPT tank mount is adjustable by hand. Simply loosen the nut and slide the alarm to the depth you want. Other mounting hardware available if needed.

Operation When there is a high or low level condition, the buzzer sounds and the beacon LED will flash. In the default mode, the user presses the button to silence the buzzer, and the LED continues to flash as a reminder. The 100dB buzzer has a unique warbling sound cuts through factory noise so it will be heard.

Different behaviors are field-selectable using DIP switches on the circuit board. Choose from:

  • 30-minute snooze alarm, (on/off)
  • tank filling mode (where it shuts off LED and buzzer until the next fillup)
  • auto/manual reset after level corrected
  • relay N.O./N.C.
  • relay output delayed 15 minutes
