4.5.2Water Detection Display

The water detection display is designed to graphically display the location of water under a raised floor when connected to an LT750 water detection system. The graphical floor plan screen shows a 30 x 16 grid. Each square represents one standard floor tile (approximately 2 ft. x 2 ft.).

Installation—LT750 DIP Switch Settings

Install the LT750 following the instructions in the LT750 user manual. The following additional switch selections should be made when connecting to an Advanced Microprocessor control:

DIP SW3-4—Off-(water alarm relay energizes for alarm)

DIP SW3-5—Off-(cable fault relay energizes for alarm)

Switch 1—Off-(LT750 sources power for 4-20 mA loop)
