DESCRIPTION
The LDRA6 is a complete monitoring system that detects and reports the presence of water and other
conductive liquids, as well as monitors dry contact alarm points. The LDRA6 couples SeaHawk Water
Leak Detection Cable (SC) with an advanced control head to monitor six individual zones. When a
conductive liquid comes in contact with the SC cable, an alarm sounds and the summary alarm relay and
zone relay activate. The LED that corresponds with the appropriate zone also illuminates and an audible
alarm is activated. Each LDRA6 input can also be configured to detect a dry contact’s change of state (NO
or NC) and annunciate the alarm on the front panel.
The LDRA6 is a supervised system - it continuously monitors the cable for leaks and cable integrity. A
cable break causes a cable fault indication. An alarm sounds and the appropriate zone relay and the
summary alarm relay activate. The appropriate LED changes to indicate a cable fault has occurred.
The dry contact relays in the LDRA6 may be configured as supervised or unsupervised (see section 2-2 for
configuration options). Each zone can be configured with unique, individual settings. When the user
specified alarm condition occurs, the LDRA6 activates the appropriate relay and alarm LED.

LDRA6 FRONT PANEL INDICATORS
1-2.1 Zone LEDs
One tri-color LED for each zone.
Default Leak Detection Cable Setting:
On solid and green for normal cable conditions.
Flashes quickly and turns red if a leak is detected in the zone.
Flashes quickly and turns yellow if a cable fault is detected in the zone.
On solid once an alarm is silenced.
Flashes quickly and turns red if a leak is detected in the zone.
Flashes quickly and turns yellow if a cable fault is detected in the zone.
On solid once an alarm is silenced.
Default Dry Contact Setting:
On solid and green for normal, non-alarm conditions.
Flashes quickly and turns red (by default) if an alarm condition is detected in the zone.
On solid once an alarm is silenced.
Flashes quickly and turns red (by default) if an alarm condition is detected in the zone.
On solid once an alarm is silenced.
1-2.2 Power LED
On (green) as long as power is on.
1-2.3 Audible Alarm
Activates when an alarm condition is detected. Silenced with the Quiet/Test/Reset switch.
1-2.4 Quiet/Test/Reset Switch
During alarm, the audible alarm is silenced, and any LED(s) in alarm will glow solidly. If the alarm goes
away, the LED(s) will flash slowly. Hold down the Quiet/Test/Reset switch to reset all alarms and
complete and self test cycle. If any alarms still exist, the unit will not reset the corresponding zones.
