• Duplex outlet gives convenient supply of 120 VAC for transformers and 120 VAC accessories.

• 10 year perforation warranty on cover and chassis with 2 years on electronics and mechanism.

CONCRETE PAD

The concrete pad for operator mounting should be approximately 24"x24"x24" in order to provide adequate
weight and structure to insure proper and stable operation. Pad should be 6" above finished grade or even with
top of curb if one is present. (NOTE: PAD SHOULD ALWAYS GO BELOW FROST LINE

WHERE GROUND WILL FREEZE!!)

ANCHORS (MOUNTING UNIT)

Proper anchors for fastening operator to pad will be a 1/2"x6" wedge anchor patterned to match the mounting

base of the unit. They should be installed with approximately 1.25" showing above concrete surface in order to
allow for the 1/2” thick base plate as well as washers for leveling.

IN REGIONS

PAGE 1

NOTE 1: MAXIMUM AMBIENT TEMPERATURE FOR INSTALLATION, 104 F.
NOTE 2: FOR AUTOMOTIVE USE ONLY, NO MOTORCYCLES, BICYCLES OR PEDESTRIANS.
NOTE 3: HEATER OPTION MUST BE USED IF TEMP IS (15F) OR BELOW TEMPERATURES.

CONDUITS

Conduits should be restricted to fit the 3.5"x3.5" opening in pedestal base. Location on pad should be
centered and spaced approximately 6" from edge of pad on drive way side ( in order to get the most reach out
of arm ). Conduits to be included should be 120 VAC main power, low voltage control wiring and one or two
extra for loop sensor leads. Conduit size should be limited to .5" when possible to reduce crowding if more
than four are needed. All conduits must be U.L. approved.

WIRING AND HOOKUP (Only by a qualified electrician/installer!)

120 VAC

Be sure your main power (120vac) is OFF before attempting hookup. The 120 volts AC supply should be
terminated to the wires in top of the 4"x4" tube at the top of the chassis. Connect the 120 VAC to BLACK wire,
Neutral to the WHITE wire and Ground the GREEN wire. Warning- Do not connect any 120 VAC wires
directly to the terminal strips on the electronic control board. Only U.L. approved 14 AWG ( or larger)
600 volt insulated wire should be used. A separate UL approved 10 amp circuit breaker should be used for
each MEGA-ARM operator. BATTERIES MUST BE INSTALLED AFTER 120VAC POWER IS TURNED ON.
See BATTERY at page 3 and 120 VAC wiring on page 4.

INPUT COMMANDS

Control wire connections at low voltage terminal strip will be at the top of the electronic control board. Make
connections to the appropriate points for the desired operation. Wires should be U.L. approved 600 volt rated
and at least 18 awg. They are to be routed through the upper grommet in chassis to avoid chafing. All external
control devices must have normally open dry contacts. DO NOT CONNECT ANY DEVICE WHICH WOULD
DELIVER ANY VOLTAGE OF ANY KIND TO THESE TERMINALS.
Terminals 9, 10, 11, 12 are the commons (0 VDC) used to activate the following inputs.

1, 2, 3 OPEN- These inputs will trigger gate open when pulsed or hold gate open with maintained contact.

When released gate will close if closing timer is on or if close input is given.

4, AUXILIARY OPEN - Same as 1,2 and 3 with S2 switch 6 off. With S2 switch 6 on, this input will memorize

multiple vehicles and not allow gate to close until the final vehicle in memory crosses the close loop. Use with
laser scanners or card readers and (transmitters with timed anti-pass back). With S1 switch 5 on, this input
becomes a momentary pulse open, pulse close.

NOTE: Insert a jumper across the JP2 terminal to allow the interlock feature (see page 5 & 14) to work with the
multiple vehicle memory count selection, use the K1 relay to open the interlocked gate (S1-5 off, S2-6 on,
jumper across JP2). This allows gate to store input counts via J5 #4 but not raise the arm until the interlocked
slide or swing gate has fully opened.

5, SAFETY- This input is generally not used with the MEGA-ARM. If used its function is to make gate reverse

and go back to the open position if it was closing. Input is disabled when gate is closed.

6, CLOSE- When used with a vehicle detector, it is recommended that the presence contacts (N.O. & C.) be

used for the close input. This input will close gate after input is applied and then removed. It will stop the open
cycle and reverse gate to close. (Example: Car crosses over close loop before arm reaches full open position­gate will reverse and close). (Note: The close input also acts as a safety-stop in that if gate is closing and a
tailgater is sensed at the close input, the gate WILL STOP its closing motion and not continue to close until the
close input is removed or gate is re-opened).

INPUT COMMANDS (Continued)

7, BACK-AWAY (FREE EXIT INPUT) This input is used as a free exit input to open gate. When input
is active, gate will open and close immediately once input is removed. (EXAMPLE: Car pulls up to
exit loop, gate opens; car "backs-away" from exit loop and gate closes).

8, SHAD- INTERLOCK (REDEFINED INPUT!!!) Used to monitor an auxiliary open limit switch of
another operator in the same lane. Interlock with memory feature (v5.20 or higher) see page 13.

9, 10, 11,12- COMMON- These are the commons (0 VDC) to be used to activate above inputs.

Note: Above inputs are tied to LED indicators to show input command activity.

ACCESSORY CONNECTIONS

These terminals will provide battery backed power to 24 VDC devices and are located at the bottom

of the electronic control board at terminals 1 and 2. Terminal 1 is 24 VDC (+) and number 2 is 0 VDC
(-). Peripheral CLASS 2 low voltage devices that require 24 VDC power maybe connected here (500
ma. maximum). EXAMPLE: Vehicle detector, radio receiver.

RELAY OUTPUT K1- (OPTION)

S1-6 off, S1-8 off
S1-6 on S1-8 off, relay will fire when arm is pushed up off of limit switch (use with slip clutch option).

and fires relay when a tail-gate is detected by the close loop -ANTI TAIL-GATE ALARM

S1-6 off S1-8 on relay will pulse relay when arm reaches full open position.
S1-6 on S1-8 on relay will only pulse when input is given to J5 1,2,3 inputs. (see page 14).

, relay will fire (latch) when gate is not closed.

BATTERY INSTALLATION

HOOKING UP BATTERY LEADS- ALWAYS HOOKUP AND TURN ON AC POWER

BEFORE INSTALLING BATTERIES. After turning on AC power, install two new, fully charged 12

volt DC batteries on shelf next to motor. Connect red lead from operator to the positive (RED +)
terminal of one battery and black lead from the operator to the (BLACK-) terminal of the OTHER
battery. Place the supplied jumper between the remaining terminals of each battery if one is not
already in place. See diagram. (USE YUASA BRAND PN#NP7-12)

WARNING-DO NOT RUN OPERATOR WITHOUT INSTALLING THE BATTERIES

MASTER SLAVE WIRING

Master-slave wire hook up.

STEP 1- In a master/slave configuration, either unit can be the master. Choose one unit to be the master and
then direct all control wiring to it (also install vehicle detector and receivers in it).

STEP 2- At the MASTER, any input (at J5) with control (detectors, receivers, keypads, timers, etc...) wires to it
must also be run to the same terminals of the slave. Along with these control wires, both operators MUST
share a common ground connection
terminal #12 to slave gate J5 terminal #12)
EXAMPLE: If only open and close are used at master then three wires will run between gates.

MASTER- J5 SLAVE-J

STEP 3- If it is required that if one gate senses an obstruction, the other reverses also, then 3 additional wires
must be run between the master J3 and slave J3 as shown below. These connections are for transmitting IRD
(obstruction signals) between both units. This will allow the master or slave to inform the other that a closing
obstruction has occurred and for it to also reverse and open. SET switches on S2, 1-8 the same on both gates
