Connects to a normally closed (or open) contact and converts it to a loud buzzer and a flashing LED. Often used with Gizmo Engineering liquid level switches. The 101 dB buzzer has a unique warbling sound that cuts through the sound of the factory.

OPERATION

At the time of a level conditions, the buzzer sounds and the beacon LED flashes. At this time the front button will turn off the buzzer. In the default mode, the LED continues to flash until the liquid level is corrected. Resets automatically when alarm condition is corrected. If not in alarm mode, then the front button checks the alarm.

Different behaviors can be selected using the DIP switches inside the box. Modes to choose from:

  • 30-minute snooze alarm.  (buzzer sounds again 30 mins. after being silenced)
  • automatic or  manual reset after level correction.
  • relay N.O./N.C.
  • relay output delayed 15 minutes.
