Installation
Installing the sensor cable
The number of cable passes required on the mounting surface depends on the height of the
mounting surface, the type of building material, and the required level of security.
•
For single cable passes attach the cable horizontally at the half-way height of the mounting
surface (see
•
For double cable passes, space the cable evenly between the bottom and the top of the
mounting surface (e.g., for a 3 m {10 ft.} wall with two cable passes one pass should be at the
1 m {3.3 ft.} level and the second pass should be at the 2 m {6.6 ft.} level) (see
•
For a triple cable pass space the cable evenly between the bottom and the top of the mounting
surface (see
Cable handling
The FlexPI sensor cable converts vibrations in the mounting surface into electrical signals, which
the cable carries back to the processor for analysis. Any damage to the sensor cable from
mishandling or poor installation practices will have a negative effect on performance. The following
is a list of cable handling Do’s and Don’ts.
•
Apply consistent light tension (approximately 2.25 kg, 5 lbs) while mounting the sensor cable.
•
Install the sensor cable in metal conduit if the cable is being installed in an area where it may
be prone to damage from vandalism, equipment, or materials (see
). DO NOT use
plastic conduit.
•
When using cable ties to attach the sensor cable to a security cage, install the ties by hand
and pull them hand-tight until snug (see
).
•
DO NOT use mechanical tighteners to attach cable ties to a security cage.
•
When attaching the sensor cable to a flat mounting surface, use fasteners that hold the cable
firmly against the surface without squeezing or distorting the cable jacket (see
•
DO NOT use a staple gun to attach the sensor cable to a mounting surface.
•
DO NOT allow the sensor cable to be pinched between the mounting surface and any object.
•
DO NOT bend, twist, or kink the sensor cable.
•
DO NOT place objects on the sensor cable or allow anyone to stand or walk on the cable.
•
Use cable loops near support structures such as wooden studs, steel beams, posts, etc. as
the support members can have a dampening effect on vibrations (see
).
CAUTION
Handle the FlexPI sensor cable with care.
