Schematic
The water sensing probes function the same as the
water leak detection sensing cable in the sensing cable.
The SDZ will technically add 1 to the overall cable
length. Company Confidential

Troubleshooting:
Verify < 1 Ohm, Pin 1 to Pin 1, Pin 2 to Pin 2, etc.
Verify an open circuit between pins (no shorts)
If water is between the probes, the meter may read 100K to 2M Ohms
between pins 2 and 3.
Testing:
Place water between the probes and verify that the LD panel alarms on leak.
Remove the water and verify the panel returns to normal.
Disconnect one end and verify the panel alarms on cable fault, reconnect the
SDZ and verify the panel returns to normal.
