FlexZone – Installation Overview


This video explains how to install
FlexZone processor and attach the sensor cables to a fence. Installation requires two people. For a site with one
or two processors, installation will typically take one day. On a normal eight
foot chain-link fence attaching the sensor cable takes about
one hour per 100 meters or 328 feet. You will require; a one meter wood dowel or rod to dispense the cable. A utility knife or coaxial cable cutter, a cordless drill and a 5/16 nut-driver bit, and a one-eighth inch slot screwdriver. If your FlexZone processor is to be connected to a network and requires a communications guide, you should install its communications card before you start
the processor installation. Refer to the included instructions for information. Select a location to install the FlexZone processor. One that minimizes the
need to run lengthy power and communication cables. Consult with your
Senstar technical representative, for information on site planning and
security considerations. The processor includes two gear clamps and is typically mounted on a pole. its mounting flanges also support wall mount applications. As an all-weather device you may install the processor outdoors or inside a building. In this video we mounted directly on the fence using the included hardware. When installing the processor on a fence always place it on the non-threat side of the fence, for example if you wish to detect intruders
outside your property, install the processor on the inside of the fence. Dispense the sensor cable in a straight line near the fence and condition it, for
information on how to perform the cable conditioning procedure refer to the
instructions included on each reel or watch the FlexZone cable conditioning
video. Using UV rated cable ties attach the sensor cable along the fence,
typically halfway up. Space the cable ties approximately every 30 centimeters
or 1 foot and maintain a consistent height on the fence. Hand tighten each
tie so that the cable is snug against Make sure you attach the cable to the middle sections of the links and not at
the intersections. To maintain the conditioning of the
cable and to ensure the correct tension secure the sensor cable to the fence by
attaching the tie wraps in the following order. When attaching the sensor cable to
the fence attach the tie wraps in the middle of a chain-link not at the
intersecting point. Tie wraps should be secure but not tight enough to collapse
the cable tube. For extra security, after the system is fully tested, add two steel
tie wraps per fence panel. note, do not use twisted wire ties as these are
intended for use only with armored cable. Every 50 meters or 165 feet, add a
service loop to allow for future adjustments. The service loop should be
30 to 45 centimeters or 12 to 18 inches in height. At corners or heavily
reinforced sections, add extra cable to form sensitivity loops. Avoid vertical
drops greater than 1 meter or 3.3 feet. For longer vertical drops, angle the
cable at 15 degrees. The cable should be snug against the posts but still movable
with your finger. When bending the cable, avoid turns or angles that cause the
hollow tube in the sensor cable to collapse. Regular FlexZone sensor cable
has a recommended minimum Bend radius of 10 centimeters or 4 inches. The collapse
in the sensor cable may prevent sensing in that area. At single or double
swinging gates, add the sensor cable to each panel 30 centimeters for one foot
from the edge. To get from one panel to the other, route the sensor cable
underneath the gate area. Sliding gates are typically protected with the FlexZone
wireless Gate sensor. Contact your Senstar technical representative for
information about the gate sensor and other sliding gate solutions. To bypass
the sliding gate, route the sensor cable and conduit underneath the gate area.
FlexZone sensor cable is available in 150 and 200 and 20 meter lengths. If you
need to splice together two cables (up to a total of 300 meters if connected to a
terminator or 600 meters if connected to an adjacent processor), you need to
use a splice kit. To attach a splice kit, remove a short length of outer jacket
and twist half of the braided shield into two prongs. Remove the aluminum
shield and trim the clear tube so that it extrudes by five millimeters, or one
quarter inch. Cut off the other half of the braided shield and trim the wires to
be flush. Attach each sensor cable to the splice kit. Fasten each cable to the
circuit board with two cable ties. Trim off the extra cable tie straps. Press the
cables and circuit board into the waterproof enclosure. Close the
waterproof enclosure, the tabs will click when locked. Attach the splice kit to the
fence. Raise it 15 centimeters or six inches above the sensor cable, so that
water drips away from it. If you have excess cable, add splice service loops so
that the extra cable can be retained for future modifications or repair. There are
two ways to terminate the end of a sensor cable. If the sensor cable is by
itself, form a u-shape and attach a termination kit. One or both ends of the
sensor cable can be attached to side a and side beat of the FlexZone processor.
If the end of your sensor cable does not connect to a processor you need to use a
termination kit. The terminator provides 47 kiloohm DC termination in parallel
with 100 ohm, AC termination. To attach a termination
kit: 1. Remove a short length of outer jacket and twist half of the braided
shield into two prongs, remove the mylar film, trim the clear tubes so that it
extrudes by 5 millimeters or one quarter inch. Cut off the other half of the
braided shield and trim the wires to be flush. 2. Attach each sensor cable to the
termination kit. 3. Fasten each cable tothe circuit boards with two cable ties, trim off the extra cable tie straps. 4. Press the cables and circuit board into
the waterproof enclosure. 5. Close the waterproof enclosure the tabs will click one locked. 6. Attach the termination kit to the
fence, raise the enclosure 15 centimeters or 6 inches above the sensor cable so
the water drips away from it. If you have excess cable, add a termination service loop so that the extra cable can be retained for future modifications or
repair. To connect the sensor cable to the processor, twist the braided shield
into two wires and trim the center conductor so that all three points end
in parallel. Attach the wires to the removable
terminal block and reattach it to the processor. The FlexZone processor
requires a 12 to 48 volt DC power supply and draws a maximum of 2.5 watts. A FlexZone processor connected to a power supply can provide power to four
additional processors (two on each side) over its sensor cable.
This means a perimeter distance of up to 3 kilometers or 9,800 feet can be
powered from one supply. The three point connection to the terminals (two grounds
plus one power) ensures a mechanically stable and strain
free connection. Once the sensor cable is connected and the FlexZone processor is
powered on, you are ready to profile the sensor cable. See the FlexZone cable
profiling tutorial for instructions.
