Duplex Alarm Systems Single Phase
The Duplex Alarm System/Pump Control provides residential and commercial customers with a reliable means of controlling a duplex (two pump) system in a water or sewage installation. The system consists of a control panel and three sensor floats. The non-corrosive, indoor and/or outdoor enclosure comes pre-assembled. The panel exterior features a large red alarm beacon. An exterior buzzer test/normal/silence switch allows the 83-85db audible alarm buzzer to be silenced or testing of buzzer and light to ensure proper operation of alarm function. The panel interior consists of two heavy-duty motor contactors, printed circuit board controller, and a standard 25 watt (max.) light bulb. Two handy HOA switches allow for either Hand (manual), Off or Automatic pump operation. A control switch turns off power to the float circuitry. The control switch and the HOA switches may be turned off to provide an additional safety feature when servicing. These switches are located inside the panel to protect against activation by unauthorized personnel. Green pump run indicator lights located on control circuit board. Easy-to-follow wiring diagram and terminal strip provide for simple installation.
