Liebert Liqui-tect™ Leak Detection
Sensors install quickly and work simply
for reliable detection of leaks.
The Liqui-tect 410 Sensor should be
placed at critical points on the floor.
Two corrosion-resistant, gold-plated
probes sense the presence of aqueous
liquids.
When a leak is detected, dual Form-C
relay outputs can simultaneously
signal a local alarm panel and a remote
monitoring system. The Liqui-tect 410
Sensor features supervised operation:
circuit failure or loss of power are
detected and indicated as alarm
conditions, providing a completely self-
monitored leak detection system.
The following pages provide the sensor
dimensions, mounting, location, and
wiring detail to install your Liqui-tect
sensor

As shown in the illustration on page 2,
Liqui-tect 410 (LT410) may be placed
on a subfloor within the leak detection
zone—the area directly beneath the
unit being protected or other areas
such as the unit drip pan or ceiling pipe
trays.
The LT410 requires a 24 VAC power
supply either from the environmental
unit or an external source. There are
two sets of Form-C dry contacts for
connection to a Liebert thermal-
management unit and an external
monitoring panel.
NOTES
This equipment has been tested
and found to comply with the limits
for a Class A digital device, pursuant
to part 15 of FCC rules. These limits
are designed to provide reasonable
protection against harmful interference
when the equipment is operated
in a commercial environment. This
equipment generates, uses, and can
radiate radio frequency energy and, if
not installed and used in accordance
with the instruction manual, may
cause harmful interference to radio
communications. Operation of this
equipment in a residential area is likely
to cause harmful interference in which
case the user will be required to correct
the interference at his own expense.
