IQUI TECT
Point Leak Detection Sensor
Description
The Liqui-tect 410
(LT410) provides a
single-point detection
of leaks. The point
detection sensor has
two gold-plated
sensing probes to
prevent corrosion
resistance and to
provide accurate
readings. The LT410
constantly monitors
points for leaks,
internal faults and power failures and warns of any
abnormal conditions. Mounting brackets allow for
sensor height adjustment and leveling.
The LT410 is the ideal solution for sensing leaks under
a raised computer floor or air conditioning drip pans.
Two independent outputs provide added flexibility
with the capacity to signal both a local alarm panel
and a remote building management system or external
equipment, such as motorized water shut-off valves.
The LT410 is also ideally suited for the following:
