Water Detector Tape Installation

Water Detection Tape Installation

Monitored by a sensing relay, the water detection tape will provide an alarm when in contact with several drops of
conductive liquid. High humidity should normally not cause an alarm unless it results in condensation dripping on the
tape surface or condensation present on the surface to which the tape is applied.
The recommended installation process is as follows:
• When applying to a surface such as concrete, the most popular method is to press the tape fi rmly onto a
continuous fi lm of approved adhesive or glue. When properly glued to the fl oor the tape lies fl at on the fl oor
avoiding "bridging" (where the detector lifts off the fl oor allowing water to run under the detector without detection)
and avoids damage to the detector
• When applying the tape directly to the piping, the tape is simply strapped to the pipe
• Care should be taken to prevent the wire detectors in the tape from coming into contact with any electrically
conductive material causing a "fault" condition. Anything used in applying the tape which interferes with the
capability of the fl eece substrate may adversely affect the detector's function
• The tape should not be installed under piping or equipment that can condense liquid as the condensation could
drip on the tape causing an alarm
• The tape should not be installed directly under an air handling unit, but around the unit
• In the sub-fl oor of a computer room the tape should be installed after the raised fl oor, conduit and piping are
installed and the sub-fl oor cleaned and sealed

Any adhesive which alters the chemical composition of the tape must be avoided and any use
thereof voids any warranty, expressed or implied. 3M Scotch-Weld™ 77 adhesive is strongly
recommended to ensure the warranty will be maintained. When adhesive is used, adhesive with
an oily or greasy base MUST be avoided as this will affect the tape's ability to detect moisture.
When the use of an adhesive is not desirable or practical, staples, clips or other devices may be
used. When applying the tape to piping a combination of glue and plastic or nylon straps or wire
ties may be used. The straps or ties help to cut down installation time and secures the tape to the
pipe while the adhesive cures and dries.
Any electrically conductive attachment devices used must not touch the wires that are within the
tape fabric. The maximum length of a detector loop, including wire and detector tape is 50 metres.
However, this tape length is not practical for most applications. Where the tape is concealed or not
easily accessible, tape runs should be limited to no more than 30 metres, and 10 to 15 metres per
zone is generally used. If the water detector tape is to be attached to or covered by a metallic or
conductive surface, care should be taken not to short the conductors.
When installing tape to any surface, be careful not to short circuit or ground out the conductors
(such as over/under conduit or sharp edges of cable trays etc.). This also applies to any covering
which may be applied over the tape. Before installing the tape, be sure to inspect areas where the
tape is to be applied for presence of chemical materials that could create problems. If in doubt, it is
recommended to clean the fl oor with a mild detergent.
