User Manual

6.1 Sensing Cable
The sensing cable shall be constructed to protect the conductors from dirt and abrasion. The cable shall be
available in 50’ and 100’ lengths, terminated with male and female connectors. The cable sections signal can
be connected together, as needed for coverage, up to a total of 1000 feet per zone. The sensing signal shall
be less than 10 vac peak to peak.
6.2 Graphic Display
A graphic overlay of the floor plan will be provided with a pattern of the cable installation and routing. The cable
shall be marked on the grid in relation to distances to make location of the leak easy to find.
7.0 Operational Characteristics
Status Indicators
1. (Green) Power On LED - This LED shall indicate the presence of normal operating power.
2. (Yellow) Trouble LED - The LED shall be lit when the water sensing calbe is no longer connected.
3. (Red) Water Alarm LED - This LED shall be lit when water is detected by the sensing cable.
4. Test Switch - This switch shall perform the following functions:
a. Light all segments of the 4-digit LED display.
b. Cause the DLS to determine the total length of the sensing cable and display the value.
c. Sound the audible alarm.
d. Close the summary alarm relay.
5. LED Display - This shall have four digits and display the water location in feet from the monitor. The
distance shall remain on the display until the reset switch is depressed.
6. Summary Alarm Relay - This relay shall energize, and the contacts change state., whenever water is in
contact with the cable, when there is a wiring fault or other systems trouble, or when the TEST switch
is depressed.
7. Reset Switch - This switch shall be used to restore the system, alarm relays, and the alarm circuit. If the
alarm condition still exists, the circuit will be retriggered.
8.0 Accuracy
The accuracy of the DLS shall be linear and within 1% of the length of cable.
9.0 Environmental Operating Characteristics
Humidity: 5 to 90% RH * Temperature: 0 to 55°C * Altitude: -250 to 10,000 Ft.
10.0 Warranty
The manufacturer of the DLS shall warrant all parts and labor for a period of one year after purchase.
