ATTACHING THE CHAIN BRACKET
The chain brackets provided with the RS1000 operator should be
mounted on the the gate with the centerline of the slot 8" above the top
of the operator pad. Attach one end of the chain to the gate and thread
the other end through the idler pulleys and drive sprocket. Attach the
free end to the bracket on the gate and tension the chain. You will
normally require a welder, or an electric drill with a 3/8" bit, for
attaching the chain brackets to the gate. See Figure 8.
PLACING THE VEHICLE DETECTOR LOOPS
Proper placement of vehicle detector wire loops is critical if the loops
are to provide satisfactory, extended service. The most important
considerations are: 1) Proper wire type and, 2) Good, tight connections
from the loop to the loop terminating connector. When a "Stand
Alone" vehicle detector is used, the detection loop is connected to the
wire harness on the detector itself. (See WIRING VEHICLE
DETECTORS, Page 11.)
The RS1000 provides for the use of a “reversing” loop that will prevent
the gate from closing on a vehicle that has stopped in the path of the
gate. Note the "reversing” loop is normally made up of two independent
loop layouts connected to one detector. See Figure 9, page 8.
Two different types of installations will usually be encountered: 1) If
the driveway material is already in place, saw cuts will be needed to
accommodate the loop wires.
2) For loops where the paving material will be installed after the loop is
positioned, it is necessary that the loop wires be placed in Schedule 40
PVC pipe to maintain uniform loop spacing with respect to the surface
of the pavement. The loop should be placed 1.5 inches below the
surface of the pavement and at least 2" above any reinforcing steel The
lead in wires need not be in PVC, but must have at least six (6) twists
per running foot.
For a saw-cut installation, observe the method recommended in Figure
9 for the corners. When installing a two-loop reversing system it is best
to bring the twisted lead wires from each loop to the operator so that the
loops may be properly phased. The saw cut must be to a depth of 1.5
inches, clean and with no sharp corners. After placing the wires, it is
essential that the wires be held tightly in place by the foam backing and
that no voids exist that can collect water which might freeze and push
the loop wires out of the slot. The sealant used should match the
paving material and should not be hard setting. The lead in wires must
have at least six (6) twists per foot.
NO SPLICES ARE ALLOWED IN THE LOOP OR THE LEAD IN
WIRE TO THE FIRST JUNCTION BOX Above ground splices may
be used providing the wire is twisted, soldered and moisture sealed.
For best long term results, do not use wire nuts anywhere in the loop
system. For connections to the loop detector, gas tight crimp type
terminals should be used, and soldered if possible.
THE WIRE USED FOR THE LOOPS MUST BE HEAT AND
WATER RESISTANT. CROSS-LINK POLYETHYLENE
INSULATED, TYPE XLPE OR RHW IS BEST. U.S.E. IS ALSO
SATISFACTORY. DO NOT USE PVC INSULATED WIRE. WIRE
SIZE SHOULD BE #16 GA STRANDED OR LARGER.

RISK OF ENTRAPMENT
VEHICLE DETECTOR LOOPS WILL NOT DETECT
SMALLER VEHICLES SUCH AS MOTORCYCLES
OR GOLF CARTS, OR BICYCLES OR
PEDESTRIANS. PHOTOELECTRIC DETECTORS,
EDGE DETECTORS AND SEPARATE
PEDESTRIAN ACCESS MUST BE INSTALLED.
