Connections and Configuration

3.1.2Connecting Leak Detection Cable to the Connection Cable

The connection cable has a black fitting on one end that will fasten securely to the fitting on one end of the leak detection cable—see Figure 8. Push these ends together, being careful to insert the pro- truding ends of the leak detection cable into the holes in the connection cable connector. Twist the connector ring to securely link the cables.

NOTE

Make sure the male end of the LT500Y leak detection cable is installed close enough to the Liqui-tect panel to reach the fitting on the CONNECT10 connection cable.

After making this connection, lay the leak detection cable around the area to be monitored.

The monitored area would include any equipment or objects that might be damaged by water. Figure 9 shows one possible layout. In the example, the detection cable crosses between air condi- tioning units and computers to alert personnel when the electronic equipment is threatened by a leak. If there is a liquid source in the ceiling, the cable can be placed there. If a raised floor is used for cool- ing, the cable can be placed underneath the raised surface.

Follow these steps in laying the detection cable:

1.Attach the end terminator to the last length of leak detection cable required to monitor the selected area.

2.Verify power is connected and test the detection cable by touching the detection cable with a clean, moist cloth or paper towel.

If the cables are connected properly, the audible horn should sound and the LCD screen should flash. Dry the detection cable to remove the alarm condition. (A hair dryer can be used to speed up the drying.)

Note: Do not try to saturate the detection cable for testing! It requires only a small amount of water to alarm. The detection cable will have to dry for the alarm condition to clear.
