PRE-INSTALLATION NOTES
The Twist’R Plus (Model RS4000) Vehicular Gate Operator will
provide convenience and assurance to the ultimate users for many
years. It is ruggedly built of the finest materials and has been
thoroughly inspected and tested at the factory. It has many features that
will aid in the installation and testing of the complete gate system. The
RS4000 has been designed and built to comply with the UL325
Standard For Safety, Fourth Edition, revised March 1, 2000 as
established by Underwriters Laboratory Inc..
NOTICE
BEFORE ATTEMPTING INSTALLATION,
READ THIS MANUAL CAREFULLY SO YOU
WILL BE THOROUGHLY FAMILIAR WITH THE
FEATURES OF THE TWIST'R PLUS AND IT’S
PROPER INSTALLATION PROCEDURES.
The RS4000 Vehicular Swing Gate Operator is designated a Class I
Vehicular Swing Gate Operator, and is intended to operate a
vehicular swing gate installed on a residential home, maximum of four
single families in the dwelling, or a garage or parking area associated
with that home, or a similar location with respect to the cycle usage (see
below). Allstar manufactures operators for the three other Class
designations (as defined by UL325); Class II (high cycle usage
commercial location or multi-family home); III (industrial location not
intended to service the general public); and IV (secure or restricted
access locations, ie. airports and prisons). The RS4000 operator cycle
usage is rated at a maximum of 10 cycles per hour, 50 cycles maximum
per day.
Because the RS4000 (as well as gate operators sold by other
manufacturers) is designed to start and move gates weighing as much as
300 pounds and 16 feet in length. As such, the RS4000 is capable of
producing high levels of force. It is important in the design of the total
gate system that designers, installers and users be aware of the hazards
that may be associated with the IMPROPER design, installation and
use of Vehicular Gate systems and Gate Operators.
The gate operator is only one part of a complete automatic gate
operating system. As each location and usage is different, a properly
designed system
As the designer and installer of the GATE SYSTEM, you must
advise the purchaser on the proper use of the gate system. You also
have the primary responsibility of insuring that ALL possible
operational hazards have been considered and eliminated.
The RS4000 CGA2K™ technology provides several features that
can help reduce the hazards of your gate system.
Built-In Adjustable Torque Limiting Drive System
The RS4000 is provided with a adjustable torque limiting drive system
that may be adjusted to “slip” when an obstruction is encountered. This
system, however, must not be considered as the primary obstruction
sensing system. Consider all available options (electric leading edges,
photoelectric sensors, protective screen mesh, etc.) to eliminate hazards
in your gate system design.
The torque limiting drive system also serves to protect the mechanical
components of the operator.
will include all applicable safety enhancement devices.
The torque limiting drive setting is an adjustable setting that must be
determined at the time of installation. This setting must be tested
periodically to ensure proper operation. The more freely the gate will
move the more sensitive the setting can be made. See Page 17.
ADVISE THE PURCHASER TO CHECK THE SENSITIVITY OF
THE GATE OPERATION PERIODICALLY AND THEN LOG THE
DATE TESTED IN THE TABLE on page 2. (See Figure 1)
THE IMPORTANT SAFEGUARDS AND
INSTRUCTIONS IN THIS MANUAL CANNOT
COVER ALL POSSIBLE CONDITIONS AND
SITUATIONS WHICH MAY OCCUR DURING ITS USE. IT
MUST BE UNDERSTOOD THAT COMMON SENSE AND
CAUTION MUST BE EXERCISED BY THE PERSON(S)
INSTALLING, MAINTAINING AND OPERATING THE
EQUIPMENT DESCRIBED HEREIN. DO NOT USE THIS
EQUIPMENT FOR ANY OTHER THAN ITS INTENDED
PURPOSE — OPERATING A SWING GATE.
Connections for External Entrapment Prevention Sensors
Because all gate system installations are different, the RS4000 control
panel provides independent connections for Open and Close contact
(edge) sensors and Close non-contact (photoelectric) sensors. In this
way a photoelectric sensor could be utilized to guard the gate area when
closing and an edge sensor would provide the protection when opening.
Depending on the particular application a combination contact and noncontact sensor protection system for the open and close directions may
provide more effective entrapment protection than a single device for
both directions. See pages 4, 5, 14, 15, 16, 20, and 21.
SMART™ Self adjusting MAximum Run Timer (Patent Pending)
The RS4000 has a Self adjusting MAximum Run Timer, SMART™
(patent pending). The amount of time for the first few cycles of
operation are registered and averaged within the motor controller
circuitry. After the first few initial cycles, if the gate is activated and no
other command is given or an end limit (open or close) is not reached in
the previously counted cycle time plus approximately 4 seconds, the
operator will be turned off. See page 19.
OTHER FEATURES
Auto Close Timer: Adjustable from 2 to 60 seconds, provides an
automatic closure of the gate from the full open position. See page 18.
Synchronous Operation (Master/Slave): Two RS4000 units can be
wired together to operate as one system, with one unit controlling the
movement of both. Additionally, the installer can customize the
installation of the external entrapment protection devices. These
devices can be wired to the controller operator or alternately to the
individual units as the situation dictates or the end user requires. See
Page 13.

TO REDUCE THE RISK OF SEVERE INJURY
OR DEATH: READ AND FOLLOW ALL
WARNING!
INSTALLATION INSTRUCTIONS AND GATE
SYSTEM DESIGN PARAMETERS!
GATE SYSTEM DESIGN AND INSTALLATION
SAFETY CHECK LIST:
• The RS4000 operator may be installed on a Class I Vehicular
Swing Gate. See page 3 for an explanation of the different
Class locations. See the last page of this manual for the
operator specifications (voltage, maximum gate weight &
length etc.).
• Make sure that the gate moves freely, all hinges are in good
working order, the gate does not bind in any manner and the
gate swing area is clean and free of irregularities. DO NOT
INSTALL THE OPERATOR UNTIL ALL GATE
PROBLEMS HAVE BEEN CORRECTED.
• Do not increase the built-in overload detector adjustment or
overtighten the torque limiter to compensate for a poorly
working gate. A well maintained gate will ensure easy manual
operation (if needed) and maximum operator obstruction
sensitivity.
• Install the operator on the inside of the property/fence line.
DO NOT install an operator on the public side of the fence line
or gate. Outward swinging gates should not open into public
areas.
• Make sure the gate operating system is placed far enough back
from the road to eliminate traffic backup. The distance from
the road, size of the gate, usage level and gate cycle/speed must
be taken into consideration to eliminate potential hazards.
• The gate must be installed in a location so that enough
clearance is supplied between the gate and any adjacent
structures when opening and closing to reduce the risk of
entrapment.
106503
Figure 3: Entrapment Zones and Pinch
• For ORNAMENTAL “GRILL TYPE” GATES (or any other
type of open gate where a handhold or toehold may be
achieved), injuries may occur when people put arms through
the openings or children “ride” the gate by standing on the bars
and holding on to the gate. THIS POTENTIAL HAZARD
CAN BE MINIMIZED BY INSTALLING A MESH SCREEN
ON THE GATE. Allstar strongly recommends the entire gate
and adjacent fence area the gate covers when open be meshed
or guarded such that a handhold or toehold cannot be achieved.
See Figure 2.
• All Allstar gate operators are VEHICULAR GATE
OPERATORS and as such are NOT RECOMMENDED FOR
PEDESTRIAN traffic. In installations where pedestrians are
likely to be nearby, install a pedestrian gate and use leading
edge detectors and/or photocells in your design to protect
system entrapment zones. Allstar can provide these products
for incorporation in your design.
• Use the illustration at left (Figure 3) to minimize the risk of
injury in your design of the swing gate operator system.
IDENTIFY THE ENTRAPMENT ZONES AND PINCH
POINT AREAS IN YOUR GATE. Design the gate
installation to minimize the risk of entrapment in these areas.
Install additional safety equipment such as four wire edges and
photocells to further minimize risk. All entrapment zones are
required to be protected.
• Entrapment Zones: Design in personal entrapment
protection devices to protect people from entrapment in the
zones shown in Figure 3 at left.
• Pinch Points: Use protective measures (guards, padded
edges, etc.) to protect people from the pinch points shown in
Figure 3 at left.

GATE SYSTEM DESIGN / INSTALLATION
• SWING GATES HAVE THE POTENTIAL HAZARD OF
HANDS AND FINGERS BEING PINCHED between the gate
edge and the post to which the gate is mounted. It is
recommended that the hinges be mounted so that this opening
increases as the gate swings open. PROTECT THIS
"PINCH POINT" SO THIS HAZARD IS MINIMIZED.
See Figure 3.
• CONSIDER ALL OTHER "PINCH POINTS" IN YOUR
DESIGN of the gate system. Observe the arm as it opens and
the two arm pieces swing past each other. Use protective
measures to reduce hazards at this location. Restrict access to
the arm motion. See Figure 3.
• DO NOT consider the adjustable torque limiter as the primary
defense system. Consider all options in the gate system
design.
• DO NOT connect any auxiliary equipment to the RS4000
(detectors, card readers, etc.) until the gate operator and all its
functions are fully tested. Only connect one device at a time
and ensure its proper function(s) before moving on to the next
device.
• DO NOT locate any control device (key switch, switch, key
pad, card reader, etc.) in a position where it may be activated
by a person reaching through the gate or while touching the
gate in any manner. Locate all control devices a minimum of
10 feet from the gate when opened or closed.
• Outdoor or easily accessible controls must be of the security
type to prevent unauthorized use of the system.
• Install all devices that will open or close the gate in such a
manner that THE GATE WILL BE IN FULL VIEW WHEN
THE DEVICE IS OPERATED.
• Before activating the "timer to close" option of the RS4000,
ENSURE THE PERSONAL ENTRAPMENT PROTECTION
DEVICES (operator reversing feature, edges, photocells) ARE
OPERATING and install VEHICLE DETECTOR LOOPS
AND VEHICLE DETECTORS for protection of user vehicles.
Read the manual for information on the installation of these
devices. IF VEHICLE DETECTOR LOOPS HAVE BEEN
INSTALLED TO PREVENT THE GATE FROM CLOSING
ON A VEHICLE, INSTRUCT THE USER TO
PERIODICALLY CHECK THE OPERATION OF THE
DETECTORS.
• USE EXTREME CAUTION WHEN WORKING NEAR THE
BELTS AND PULLEYS when the operator cover is removed.
Apply power to the operator only when instructed to do so.
• When the RS4000 Control Box cover is removed, high voltage
will be exposed. EVEN IF THE RED POWER LIGHT IS
NOT LIGHTED, HIGH VOLTAGE AC MAY STILL BE
PRESENT ON TERMINALS L1 AND L2. NEVER LEAVE
THE INSTALLATION WITH THE CONTROL BOX
COVER REMOVED.
• ALWAYS TURN OFF THE POWER BEFORE
ATTEMPTING SERVICE OF EITHER THE ELECTRICAL
OR MECHANICAL SYSTEMS.
• SECURELY ATTACH THE WARNING SIGNS provided
with the RS4000 on the gate (one on the outside and one on the
inside) where they can be seen by persons in the area of the
gate to alert them of automatic gate operation. The installation
of the warning signs is a requirement of UL325 and as such
failure to install the signs will negate the UL Listing.. If the
user refuses to have the warning signs installed, Allstar
recommends that you note this on your records and have the
user sign a disclaimer. See Figure 4.

Figure 5: Pad Configuration
THE CONCRETE PAD
The standard RS4000 is designed to operate a single leaf gate. Biparting gate systems are possible with the addition of a second
RS4000 operator. (Consult the factory.) Each RS4000 has its own
dedicated control board contained within the operator cover. Care
must be taken to provide separate high voltage and low voltage
conduits to each operator. (See Figures 5 and 6.) Care must also be
taken in choosing proper placement of the conduit to avoid
interference with the swinging crank arm which connects to the output
shaft. See Figure 8A for basic dimensions and guidelines. Figure 10
illustrates the full sweeping area which the crank arm will encompass
in a typical gate installation.
If the optional pedestal kit is used, the Installation of the RS4000
Mechanical Unit will
require a suitable concrete
pad as a mounting base. The
dimensions of the concrete
pad should be sufficient to
allow at least 5" of
clearance from each edge of
the pad to the nearest
pedestal mounting hole. The
top of the pad should be at
least 3" above grade to raise
the operator above any
standing water. The depth of
the pad below grade is
dependent on the weight and
size of the gate and the soil
conditions at the site of the
installation. ALWAYS
FOLLOW LOCAL
BUILDING CODES.
If no suitable concrete
base exists, a pad must be
poured. See Figurez6 for
plans for this pad. If the
location of the operator is
such that vehicles have
the potential of hitting the
operator, consideration
should be given to
installation of protective
posts in front of the operator.
If a suitable concrete base already exists
for mounting the operator it will be
necessary to drill mounting holes for the
RS4000 operator. 3/4" mounting holes are
located on the front and rear of the optional
pedestal. The bolt pattern is shown in
Figurez6. The mounting bolts should be
1/2" diameter or larger. "Red head" or
wedge anchor concrete bolts are usually
satisfactory.
If mounting anchor bolts are to be installed prior to
pouring the pad, pay particular attention to the bolt
pattern and the location of the mounting holes with
respect to the center line of the gate hinge
the proper operation of the Arm that the center line of the
output shaft of the RS4000 operator be located exactly as
shown on the bolt pattern drawing, Figure 6.
. It is critical for
ALTERNATE 4 X 4 POST MOUNT
The RS4000 operator offers an alternative to the optional pedestal kit
for mounting installation. A standard architectural 4 x 4 x 1/8 wall
steel tube may be substituted for the pedestal and installed in a similar
manner to a fence post: Dig a hole of proper diameter (approximately
12”) and suitable depth per local codes, and set the 4ZxZ4 post in
concrete. Make sure the post is plumb and level. The top of the post
should be cut off clean and square and should extend at least 18”

above grade. Two 13/32 diameter holes will need to be drilled on
each side of the 4 x 4 tube. Center each pair of holes on the face of
the post 2-5/8” apart and 7/8” down from the top. Each pair of holes
is to align with the pre-drilled holes in the chassis mounting angles of
the RS4000. See Figure 6 for locating the post relative to the gate,
noting that the center of the output shaft is located 4 5/8” away from
the center of the post, or 2 5/8” away from the face of the 4 x 4 post.
PLACING THE VEHICLE DETECTOR LOOPS
If vehicle detectors are to be used with the RS4000, the "loops" to be
buried in the drive should be installed during the site preparation
phase of the installation. Proper placement of the 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. The termination of the loop wires will be at the
vehicle detector itself, and not at the RS4000 terminal panel. Observe
the wiring diagram supplied by the vehicle detector manufacturer.
The vehicle detector may be mounted inside of the RS4000 operator
cover, provided there is adequate room. The AC power service
delivered to the RS4000 operator may be tapped to provide 115 VAC
service to the vehicle detector.
Two different types of loop installations will usually be encountered
when placing the loops in the drive: 1) If the driveway material is
already in place. saw cuts will be needed in which to place the loop
wire. 2) For loops where the paving material will be installed after
the loop is positioned, it is necessary to place the loops 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" 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)
OUT
twists per running foot.
THE LOOP WIRES MUST BE CONTINUOUS. NO SPLICES OR
CONNECTIONS IN THE LOOP ARE TO BE PERMITTED
BELOW GROUND. THE ONLY CONNECTION WILL BE AT
THE TERMINATION OF THE WIRE AT THE VEHICLE
DETECTOR. 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. Connect to the
vehicle detector harness by soldering.
For saw-cut installations, observe the methods recommended in
Figure 7, above. The saw-cut must be to a depth of 1.5", clean and
with no sharp corners. After placing the wires, it is essential that the
wires be held tightly in place by a foam backing prior to pouring the
sealant. THIS IS ESPECIALLY IMPORTANT WHEN FREEZING
IS LIKELY. No voids should exist that will permit the collection of
water that might freeze and push the loop wires out of the slot. The
sealant used should not be hard setting and should be suitable for
pavement material.
THE WIRE USED FOR THE LOOPS MUST BE HEAT AND
WATER RESISTANT, CROSS-LINK POLYETHYLENE
INSULATED. TYPE XLPE IS BEST. RHW IS O.K. DO NOT USE
ANY PVC INSULATED WIRE. (PVC insulation will absorb
moisture that may affect Detector operation.) WIRE SIZE SHOULD
BE #16 GA. STRANDED OR LARGER.
7
B: PREPARING THE SITE
VEHICLE DETECTOR LOOP BLANKING FOR
SWING GATES
The inside loop for a swing gate installation must be located at least
4 feet outside of the arc of the gate. If it is not, the vehicle detector
may detect the gate as it moves over the loop and cause the gate to
reopen. If the gate is large and a single leaf, the arc usually requires
that the loop be a considerable distance from the closed gate position.
This may not be an effective position for the loop. In this case, a
“blanking” or “shadow” loop may be used.
A shadow loop detector is connected to the shadow loop terminal
(#9) and the “common” terminal (#16) of the RS4000 control panel.
Now, when the gate is in the fully open or closed position the vehicle
detector will prevent the gate from closing when a vehicle is over the
shadow loop. When the gate is opening or closing, the loop input is
disabled.
ELECTRICAL POWER REQUIREMENTS
The RS4000 is a 115 Volt AC gate operator. The AWG wire size for
the electrical service is dependant upon the distance from the
operator to the service breaker panel. Refer to Table 1 to determine
the correct wire size to use. A 15 Amp service is required for each
operator unit.
The Nominal Distance column of Table 1 is the maximum
recommended distance from the service breaker panel to the operator
for a given wire size and voltage. The values in the table are valid for
one RS4000 only. The RS4000 will operate at a voltage as low as
105 VAC as measured at the input terminals to the operator. This
should be checked as part of the installation procedure.
Class 2 low voltage wiring from external controls such as a key pad,
card reader, telephone entry device, etc. must be brought to the
RS4000 operator by a separate conduit from the 115 VAC electrical
hook up conduit. Low voltage control wires MUST NEVER be
routed in the same conduit as the HIGH VOLTAGE power wires.
SERVICE CONDUIT
For new installations the conduit for the High Voltage may be
brought to a junction box near where the RS4000 operator will be
located or it may be brought directly to the 2 x 4 handy box inside
the operator.
WARNING!
AVOID ELECTROCUTION:
DO NOT ROUTE LOW VOLTAGE WIRES
IN SAME CONDUIT AS HIGH VOLTAGE
WIRES. FOLLOW ALL LOCAL
ELECTRICAL CODES OR THE
NATIONAL ELECTRICAL CODE.
