Zone Leak Detection Controller
Zone Leak
Detection Panels
DESCRIPTION
LD300, LD1000, and LDRA6 control panels continuously monitor up to 1,000 ft.
(300 ft. for the LD300) of SC, SC-Con, or SC-H detection cable per zone. If the cable
detects fluid at any point along its length, the detection panel illuminates the
corresponding zone LED, clearly indicating which zone is affected. An alarm (visual
for LD300, audible for all others) signals the presence of a leak. Additionally, if the
cable fails or loses continuity, the panel will activate a cable fault LED. The detection
sensitivity can be set independently for each zone. A summary alarm relay output is
standard.
The LDRA6 can interface with a computer via an RS-232 port, through which 117
days of cable current level readings and the last 100 alarms can be accessed for
analysis. The LDRA6 also offers a Modbus slave port allowing other devices to
communicate with it.
APPLICATIONS
●
Monitoring data centers, computer room under-floor areas, mechanical rooms,
and electrical control centers
● Protecting records storage rooms
● Monitoring plumbing in facilities
● Monitoring chilled beams
● Monitoring chemical and fuel storage areas
FEATURES
●
Monitor up to 1,000 ft. (300 m) of water leak detection cable per zone with the
LD100 and LDRA6 or 300 ft. per zone with the LD300...application flexibility
●
Two LED indicators per zone...leak and cable fault (LD1000 and LDRA6)
● Sensitivity settings for each zone help eliminate false alarms...maximum
detection accuracy
● Summary alarm relay output...fast response
● Alarm and trend logs of the last 100 alarms and 117 days of cable current levels,
plus RS-232 and Modbus RS-485 ports (LDRA6 only)...output versatility
