- Model AB-2R - Alarm Box AC Power with Relay



The ALARM PANEL BOX takes inputs from float switches or other contact closures and singals the event with a bright flashing 360-degree beacon LED and very loud buzzer.

  • Flashing beacon light is bright enough to be visible in daylight.
  • Loud warbling tone cuts through the loudest industrial noise.
  • Rugged. Built for rough, wet and corrosive environments. Washdown duty.
  • Always on duty because it uses uninteruptible battery power.
  • Illuminated push button indicates power present.
  • Compact - box measures only 4 x 4 x 2 inches.
  • Relay Ouput - 15A relay controls pumps to 1 HP.


THE ALARM BOX WITH RELAY takes a contact closure from sensing devices such as a float switch, reed switch, or limit switch, and turns it into an audio and visual alarm that can't be ignored.

  • When a contact closes the pushbutton illuminates, the beacon flashes, and the audio buzzer sounds. The button isilences the audio buzzer while the beacon light continues to flash as a reminder until the alarm condition is corrected. Resets automatically for the next alarm.
  • A 'snooze-alarm' mode repeats the buzzer output every 30 minutes if desired.
  • Pushbutton tests the circuit when unit is not actively alarming.
  • Illuminated push-button confirms that power is present.
  • Level control mode will turn a pump on and off to regulate liquid level between two points using the 15A relay option.

Simply connect to your sensor with contact close and plug in the power cord.
