Important Safety Information
Both the installer and the owner and/or operator of
this system need to read and understand this
installation manual and the safety instructions
supplied with other components of the gate system.
This information should be retained by the owner
and/or operator of the gate.
WARNING! To reduce the risk of injury or death
1. READ AND FOLLOW ALL
INSTRUCTIONS.
2. Never let children operate or play with
gate controls. Keep the remote control
away from children.
3. Always keep people and objects away
from the gate. NO ONE SHOULD
CROSS THE PATH OF THE
MOVING GATE.
4. Test the gate operator monthly. The
gate MUST reverse on contact with a
rigid object or stop when an object
activates the non-contact sensors. After
adjusting the force or the limit of travel,
retest the gate operator. Failure to
adjust and retest the gate operator
properly can increase the risk of injury
or death.
5. Use the emergency release only when
the gate is not moving.
6. KEEP GATES PROPERLY
MAINTAINED. Read the owner’s
manual. Have a qualified service person
make repairs to gate hardware.
7. The entrance is for vehicles only.
Pedestrians must use separate entrance.
8. SAVE THESE INSTRUCTIONS.
There are three kinds of safety issues involved with an
automatic gate operator: issues arising from the design
of the gate, from the installation of the gate and the
operator, and from the use of the gate operator. The
following information is designed to help you be sure
your gate and its operator are well-designed, installed
correctly, and used safely.
Gate Design
1. A gate is a potential traffic hazard, so it is im-
portant that you locate the gate far enough away
from the road to eliminate the potential of traffic
getting backed up. This distance is affected by the
size of the gate, how often it is used, and how fast
the gate operates.
2. The operator you choose to install on your gate
must be designed for the type and size of your gate
and for the frequency with which you use the
operator.
3. Your gate must be properly installed and must
work freely in both directions before the automatic
operator is installed.
4. An automatic operator should be installed on the
inside of the property/fence line. Do not install the
operator on the public side of the property/fence
line.
5. Pedestrians should not use a vehicular gate system.
Prevent such inappropriate use by installing
separate gates for pedestrians.
6. Exposed, reachable pinch points on a gate are
potentially hazardous and must be eliminated or
guarded.
7. Outward swinging gates with automatic operators
should not open into a public area.
8. The operating controls for an automatic gate must
be secured to prevent the unauthorized use of those
controls.
9. The controls for an automatic gate should be
located far enough from the gate so that a user
cannot accidentally touch the gate when operating
the controls.
10. An automatic gate operator should not be installed
on a gate if people can reach or extend their arms or
legs through the gate. Such gates should be guarded
or screened to prevent such access.
Installation
1. If you have any question about the safety of the
gate operating system, do not install this operator.
Consult the operator manufacturer.
2. The condition of the gate structure itself directly
affects the reliability and safety of the gate
operator.
3. Only qualified personnel should install this
equipment. Failure to meet this requirement could

3
cause severe injury and/or death, for which the
manufacturer cannot be held responsible.
4. The installer must provide a main power switch that
meets all applicable safety regulations.
5. Clearly indicate on the gate with a minimum of 2
warning signs (visible from either side of the gate)
that indicate the following:
• The gate is automatic and could move at
any time, posing a serious risk of
entrapment.
• Children should not be allowed to operate
the gate or play in the gate area.
• The gate should be operated only when it
is visible to the operator and the when the
area is free of people and obstructions.
6. It is extremely unsafe to compensate for a damaged
gate by overtightening a clutch or increasing
hydraulic pressure.
7. Devices such as reversing edges and photocells
must be installed to provide better protection for
personal property and pedestrians. Install reversing
devices that are appropriate to the gate design and
gate application.
8. Before applying electrical power, be sure that the
voltage requirements of the equipment correspond
to your supply voltage. Refer to the label on your
operator system.
Use
1. Use this equipment only in the capacity for which it
was designed. Any use other than that stated should
be considered improper and therefore dangerous.
2. When using any electrical equipment, observe
some fundamental rules:
• Do not touch the equipment with damp or
humid hands or feet.
• Do not install or operate the equipment
with bare feet.
• Do not allow small children or incapable
persons to use the equipment.
3. If a gate system component malfunctions, turn off
the main power before making any attempt to repair
it.
4. Do not attempt to impede the movement of the
gate. You may injure yourself as a result.
5. This equipment may reach high temperatures
during operation; therefore, use caution when
touching the external housing of the operator.
6. Learn to use the manual release mechanism
according to the procedures found in this in-
stallation manual.
7. Before carrying out any cleaning or maintenance
operations, disconnect the equipment from the
electrical supply.
8. To guarantee the efficiency of this equipment, the
manufacturer recommends that qualified personnel
periodically check and maintain the equipment.

The Control Panel
The 412 low voltage operator must be installed with the
424 MPS control panel.
The 424 MPS control panel allows you to set these
parameters:
• The sensitivity of the electronic clutch
• The operating logic (A or EP mode)
• The pause time
• How the gate responds to multiple activation
signals
• The number of operators
• The reversing stroke function
• The behavior of triggered reversing devices
• The leaf delay for overlapping leaves

Unpacking the Operator
When you receive your 412 Compact Operator,
complete the following steps.
Inspect the shipping box for physical damage such as a
torn carton. Then inspect the operator after you remove
it from the box. Notify the carrier immediately if you
note any damage because the carrier must witness the
damage before you can file a claim.
As you unpack the box, insure that all the parts listed
below are included (also see Figure 1). Your kit (a pair
of operators) has these parts:
1- 14” x 16” fiberglass enclosure with 424 MPS
control panel. Power input terminals, a power
disconnect switch, a 110v receptacle, and a test
button will be installed on the backplate. Two 12v
batteries and a plug in transformer will also be
included in the enclosure.

The 412 Low Voltage Operator
General Characteristics
The FAAC 412 Compact Operator is an automatic gate
operator for a swinging gate leaf. The 412 Compact
Operator is useful in apartment and other residential
applications and can accommodate a gate leaf up to 6 ft
(1.8 m) long.
The self-contained 412 Compact Operator consists of an
electric motor that drives a worm screw housed in an
aluminum casing.
The locking the 412 Operator provides in the fully
opened and fully closed positions is a service device
rather than a security device. Additional, external locks
are recommended under the following conditions:
• The gate face is solid.
• The installation requires tight security.
• The site is subject to vandalism.
• The site is subject to strong or very gusty wind.
For gates with two leaves, two operators are installed.
Each of them is designed for either the right or left gate
leaf: If the hinge is on the left as you face the gate on
the side where the operator will be installed, you want a
left or SX version; if the hinge is on the right when you
face the gate on the side where the operator will be
installed, you want a right or DX version. A kit has one
right and one left version (see Figure 2).
In two-operator gate installations, both operators are
wired to one control panel. In such gate installations,
one leaf can be wired and programmed to close slightly
later than the other leaf to accommodate overlapping
gate designs.
The 424 MPS electronic control panel is a
microprocessor-based controller that accepts a wide
range of product accessories and reversing devices, thus
allowing for flexible gate system design. The control
panel sets the closing leaf delay, the opening/closing
time, the pause time, the torque, the operating logic of
the gate system, the function of the reversing stroke
(required for some electric locks), and the behavior of
triggered reversing devices during the closing phase.
For its protection, the single-phase, bidirectional motor
shuts off automatically if its operating temperature
reaches 284 deg F (140 deg C). Also for the protection
and proper operation of the 412 Operator, each gate leaf
on which it is installed must have a fixed positive stop
in both the opened and closed positions.
The force of the 412 Operator is controlled by a DIP
switch located on the 424 MPS control panel. FAAC
recommends that the gate leaf stop if it encounters a
force of more than 33 lb (15 kg).
Reversing devices (such as inductive loops and
photocells) should be installed to provide non-contact
reversing operation.
Operating Logic
Manual Release Mechanism
The Manual Release mechanism is a built-in release
device of the 412 Operator (see Figure 3). To access the
keyhole, remove the plug on the top of the motor
housing. Then insert the key and turn it a half turn in the
direction of the gate’s closing to disengage the
operator’s motorized operation. You can now move the
gate leaf by hand to open or close the gate. Operating
the gate leaf by hand is necessary during installation
and is useful during power failures.

key and turn it in the

Figure 3. Use the Manual Release key to
disengage the 412 Operator from its motor so
that you can move the gate leaf by hand in the
opening or closing direction
You re-engage the motor of the operator by turning the
key one full turn in the direction of the gate’s opening.
Remove the key and replace the plug.

7
General Operating Logic
Given the electromechanical nature of the 412 Operator,
the behavior of the operator when it encounters an
obstacle is always the same no matter which logical
mode of operation has been set on the control panel.
If an obstruction interrupts the gate’s opening, the gate
will reverse it’s motion and close.
WARNING! The pressure the gate leaf applies
to an obstruction is determined by the force
adjustment setting.
If an obstacle interrupts the gate’s closing, the gate will
reverse it’s motion and open. This will not inhibit the
automatic close if you are using it.
If an obstacle interrupts the gate’s travel twice in
succession, the gate will stop and wait for another
activation input. This will cause the gate to run at slow
speed for one cycle to ensure that the obstacle has been
removed.
Logical Operating Modes
Note: FAAC strongly recommends the use of
reversing devices no matter which logic you
choose for your gate operation.
The logics available on the 424 MPS control panel are
briefly described below:
• A (automatic): The gate opens on command
and automatically closes after a pause phase. A
second command on opening is ignored; a
second command during closing reopens the
gate. A maintained signal holds the gate open.
• EP (semi-automatic, step by step): This
mode requires a command to open and a
command to close. A second command during
opening or closing causes the gate leaves to
stop all motion. A third command then
reverses the previous motion of the gate leaves.
Installation Instructions
Installing the 412 Operator involves preparing the
gate, installing the operator(s), installing the control
panel, and setting other operational controls.
Note: The following installation instructions
assume you are fully capable of installing an
electromechanical operator on a gate. This
manual does not instruct you in designing a gate,
installing a gate (whether on masonry, wood, or
metal posts), or basic electrical wiring. The
installation tasks discussed in this manual are
tasks particular to the 412 Operator.
Prepare the Gate
Before you install the 412 Operator, you need to
prepare the gate itself for the operator. Be sure to do
the following three things:
1. Make sure that the gate structure is solidly built.
2. Make sure that the gate moves smoothly on its
hinges without excessive friction by swinging it
opened and closed by hand. Lubricate all the
gate's moving parts.
3. Provide positive stops for the gate leaves in the
opened and closed positions (see Figure 4).
Figure 4. Provide positive stops for the gate
leaf

Install the Operator
Follow the instructions that follow to install your
operator whether in an inward or outward swinging
configuration.
Installing the operator consists of the following steps:
• Attach the rear mounting bracket
• Attach the operator to the rear mounting
bracket
• Attach the operator to the front mounting
bracket
• Attach the front mounting bracket to the
gate leaf
• Attach the Operator cover
• Install the 424 MPS control panel
• Set Operating controls
Attach the Rear Mounting Bracket
Attach the rear mounting bracket according to the
dimensions in Figure 5 (inward swing) or Figure 6

Attach the Front Mounting Bracket
to the Gate Leaf
Disengage the operator’s worm screw drive from its
motor with the Manual Release. Insert the key in the
top of the motor assembly, and turn the key a half turn
in the direction of the gate’s closing.
You should be able to lengthen or shorten the cylinder
by pulling or pushing it. Lengthen or shorten the
operator to the required distance for your gate
installation:
Inward swinging: Lengthen the worm screw
completely and push the cylinder in one
inch.
Outward swinging: Shorten the worm screw
completely and then pull the cylinder out
one inch.
With the gate in the fully closed position, temporarily
clamp the front mounting bracket (previously attached
to the operator) to the gate leaf and insure that the
cylinder is level.
Move the gate leaf by hand to the fully opened
position against the gate stop and insure that the
cylinder is level.
Next, you must determine that the worm screw has not
reached the full extent of its travel (bottomed out).
Remove the operator from the front mounting bracket
and push or pull the cylinder in the direction of it
opening direction of travel:
Inward swinging: You should be able to push
the cylinder in about an inch.
Outward swinging: You should be able to pull
the cylinder out about an inch.
If the worm screw was not at the full extent of its
travel when attached to front mounting bracket, then
with the operator detached from the front mounting
bracket, permanently attach (weld) the front mounting
bracket to the gate leaf (see Figure 9).
WARNING! Allowing the cylinder to bottom
out can seriously damage the operator.
WARNING! Do not weld the front bracket to
the gate with the operator still attached. Weld
splatter will seriously damage the cylinder.
Figure 9. Weld the front mounting bracket into
position after insuring the operator is level in
the fully closed and fully opened positions
If the worm screw was at the full extent of its travel,
try moving the front mounting bracket toward the
hinge and retesting. If the cylinder still bottoms out,
then the rear mounting dimensions are incorrect (see
Figure 5 or 6, whichever applies to your installation).
Reattach the rear mounting bracket as necessary.
Once the front mounting bracket is welded in place,
you can reattach the operator to the bracket.
Attach the Operator Cover
Once the operator is attached to the gate leaf, you next
prepare the cover for installation.
Caution: If you did not correctly establish the
orientation of the gate leaf and properly
install the DX model on the right side and SX
on the left side, you will be unable to install
the cover on either operator.
Position the mounting insert inside the aluminum
cover and then slide the aluminum cover into position.
Secure the cover and insert with the short screws
provided (see Figure 10).
The plastic cover insert
has a slot that must align
with the slot in the cover

Install the 424 MPS
Control Panel
Locate the control panel in the most convenient
position possible, considering the movement of the
gate. Figure 11 shows the typical layout for a two-leaf
gate system.
Installing the control panel consists of the following
general steps:
• Connect the Main Power Supply
• Connect the Batteries
• Connect the Operator(s) to the Control Panel
• Connect other Devices
• Set Operating Controls
The installer is responsible for providing the main
power breaker switch and for making sure that the
entire gate system meets all applicable electrical codes.
Connect the Main Power Supply
WARNING! Turn the main power off before
you make any electrical connections or set
any switches inside the control panel box.
When connecting power to the 424 MPS control panel,
you have two options (See Figure 12):
1. Run 115 VAC to the control box terminal,
plug the power supply transformer
(provided) in to the receptacle, and run the
22 VAC to the 424 MPS.
2. Plug the power supply transformer into
another 115 VAC outlet and run the 22 VAC
to the 424 MPS in the control box.
The installer is responsible for insuring that the power
supply transformer (provided) is used. Whether you
plug it into the duplex receptacle in the control box,
or use another receptacle, be sure that it is connected
to a dedicated circuit protected by a circuit breaker.
All wiring should conform to applicable electrical
codes, and all wiring and fittings should be
weatherproof and/or suitable for burial.

WARNING! The control panel will not function
unless the batteries are connected.
Connect the two 12 volt, 7 amp hour batteries in series
to terminals 3 and 4 on the M1 terminal block. (See
Figure 14)
The batteries will provide back up power in the event
that the AC power supply fails. When fully charged,
the batteries can provide power for up to 50 cycles
depending on gate size, wind load, force setting, etc.
Accessory Power
WARNING! Turn the main power off before you
make any electrical connections or set any
switches inside the control panel box.
Terminals 5 and 6 on the M1 terminal block provide a
24 volt dc output for accessories. Terminal 5 is positive
and terminal 6 is negative. Maximum output is 500mA.
Connect the Operator(s) to
the Control Panel
WARNING! Turn the main power off before
you make any electrical connections or set any
switches inside the control panel box.
Using a Junction Box
Connecting your operator(s) to the control panel may
require the use of one or more junction boxes. Whether
you need 0, 1, or 2 U.L. Listed junction boxes depends
on your gate design (refer to Figure 13).
If any operator is more than 2 ft away from the U.L.
Listed control panel enclosure, the connection must be
made inside a junction box. Use a U. L. Listed cord grip
where the operator cord enters the junction box; use
conduit between the junction box and the enclosure.

Connecting the Operator(s)
If your gate system has one operator, connect the brown
and blue wires from your operator to the terminals 7 and
8 in terminal block M2 for Motor 1.
If your gate system has two operators, connect the
second operator to terminals 9 and 10 in terminal block
M2 for Motor 2.
Note: If you want to delay the closing of one gate
leaf in a two-leaf gate design, be sure to connect
it’s operator to Motor 1 (terminals 7 and 8).
Connect Other Devices
WARNING! Turn the main power off before you
make any electrical connections or set any
switches inside the control panel box.
Electric Lock
If you are using the FAAC Electric Lock connect it to
terminals 11 and 12 on the M2 terminal block. These
terminals provide 24vdc to release a lock when the gate
begins to open. If you have any problems with the lock
releasing due to back pressure, it may be necessary to
utilize the reversing stroke feature by turning DIP
switch 5 on.
Flashlight
Terminals 12 and 13 provide a 24vdc output (15W max)
that may be helpful during the programming stages.
During programming the output will flash every ½
second during opening and every 1-½ seconds during
closing. If you are in the automatic mode, upon
reaching the open stop, the output will remain on for 5
seconds to inform you that the gate will close
automatically. It will also flash for up to 10 seconds if
the gate is open and a safety is triggered.
Warning Light
Terminals 12 and 14 provide a 24vdc output (3W max)
for a warning light. The light is off when the gate is
closed, and comes on during the opening, open, and
closing of the gate.

16
Activation Devices
The activating devices for your gate must have normally
open (N.O.) contacts. Connect the devices to terminals
16 and 19. Multiple activation devices should be
connected in parallel.
Note: The way that the control panel responds to
an input from an activating device depends on
how DIP switches 2 and 3 are set.
If you have a dual gate and want to have a certain
activation device open one leaf only, connect it to
terminals 15 and 19. Multiple devices should be
connected in parallel.
In the automatic mode, a maintained activation signal
will hold the gate(s) open until the signal is removed.
FAAC Radio Receiver
If you are using the FAAC plug-in receiver, connect it
to the five prong plug labeled “M5” on the 424 MPS
control panel. The orientation in which you plug the
receiver in is indicated by an outline of the receiver
printed on the 424 MPS circuit board.
Reversing Devices
Reversing devices include photobeams and other
devices that keep the gate from opening or closing when
something or someone is in the way. All of the
reversing devices should have contacts of the normally
closed (N.C.) type. Multiple reversing devices should be
connected in series.
Note: A reversing device is required for a U.L.
recognized installation.
Note: The way that the gate responds to an
input from a reversing device depends on how
DIP switch 4 is set.
FAAC International, Inc., strongly recommends that
you install reversing devices. If you choose not to install
such devices, then you must install a circuit between
terminals 17 and 19.
Stop Devices
The stop button you install must have normally closed
(N.C.) contacts. Multiple stop buttons must be wired in
series. Connect your stop device between terminals 18
and 19.
Note: If you choose not to install a stop button,
you must install a circuit between these
terminals for the control panel to work.
The LED Indicators
The three light-emitting diodes (LEDs) on the control
panel can be used to check the proper function of the
devices you attach to the control panel and indicate
whether there is power to the panel.
The POWER LED (DL1) indicates whether power is
present on the control panel. The FTO (DL2) and
STOP (DL3) LEDs indicate whether the input circuits
for reversing and stop are open or closed. If the light is
on, the circuit is closed. If the light is off, the circuit is
open. See the table below for details.

WARNING! Turn off the main power before
you make any electrical connections or set any
switches inside the control panel box.
The 424 MPS has a block of seven DIP switches that
are used to set how the control panel operates and
responds to inputs. Use the following table to set the
switches appropriately for your installation.

Programming
Note: The operator(s) will run at slow speed
during the programming phase.
Note: The batteries must be connected for the
control panel to function during the programming
phase.
The 424 MPS features a self-learning function for
programming the motor run time, pause time, and
deceleration of the 412 Operator(s). Follow the
procedure below to complete this function.
1. Manually release the 412 operator(s), move the
gate(s) to the halfway position, and reengage
the operator(s). See figure 3.
2. Turn the power to the control panel on. Ensure
that the power LED (DL1) is illuminated.
3. Turn the S2 switch (located to the right of the
other DIP switches) to the PROG (ON)
position. See figure 14. If you have a 24v
flashlight connected to terminals 12 and 13, it
should illuminate at this point.
4. Give the control panel an activation signal with
any normally open device connected to
terminals 16 and 19 or with the plug in FAAC
radios. When the signal is given, the gate(s)
should close. Motor 2 should close first,
followed shortly by Motor 1.
5. If either gate moves toward the open position,
touch the two RESET (JMP1) pins (located
between the M5 connector and the
microprocessor, see figure 14) with a small
screwdriver or piece of wire. This will cause
the gates to stop.
6. Disconnect the power to the control panel and
reverse the wires of any motor that ran open.
Reconnect power and start again at step 1.
7. Once the motor(s) is (are) running toward the
close position, it (they) should do so until the
closed positive stop(s) is (are) reached.
8. After two seconds, Motor 1 should begin to
run open, and after another two seconds, (if
you have a dual gate) Motor 2 should run open.
It (they) should continue until the opened
positive stop(s) is(are) reached.
9. When the gate(s) reach the open position, the
control panel begins to count the pause time.
Once the desired pause time (time before
automatic close) has elapsed, give the panel
another activation signal. Motor 2 should
begin to close, followed by Motor 1 (time
depends on DIP switch 6 setting). The gate(s)
should run until the closed positive stop(s) is
(are) reached.
10. Programming is now complete. Turn the S2
switch back to the OFF position. If you have
the 24v flashlight connected, it should go out
at this point.
Electronic Clutch
The 424 MPS control panel features an Electronic
Clutch that can sense when the gate(s) have
encountered an obstruction. When this happens,
the gate(s) reverse direction. Be sure to set DIP
switch 1 for your desired force/ sensitivity ratio.
In the event that two obstacles are sensed in
succession, the motor(s) will stop. At this point the
control panel will require an activation signal
which will cause the motor(s) to run open and then
close at slow speed to reprogram the location of the
opened and closed positive stop(s).

Maintenance
The 412 Operator
The FAAC 412 Operator requires no maintenance.
Periodically inspect the operator, however, to confirm
the suitability of the hardware.
The Control Panel
The control panel requires no maintenance, but every
six months you should verify that the torque adjustment
setting is appropriate. FAAC recommends that the
torque be set so that the gate leaf stops if it encounters a
force of more than about 33 lb (15 kg).
Troubleshooting
WARNING! Turn the main power off before you make any electrical connections or set any
switches inside the control panel box.
Problem: The gate does not respond to an activating
signal.
Solutions: Verify that you have correctly wired the
operator to the control panel.
Verify that you have correctly wired the activating
device to the control panel.
Check the LED DL3. The LED should be illuminated.
If it is not, then the stop device is preventing your gate
from opening or closing.
Check fuses F2 (for the motor[s] of the operator[s]) and
F1 (for accessories such as activating devices). If
necessary, replace a blown fuse.
Verify that your activating device works properly. Use
an ohm meter to determine that the contacts are open
normally and close when you activate the device.
Problem: The radio controlled opener does not open
the gate.
Solutions: Check the light on the front of the remote
transmitter. It should illuminate when you signal the
gate. If it does not illuminate and if the batteries are
okay, repair or replace the transmitter.
Be sure that the radio receiver is plugged in properly.
Be sure that the LED on the receiver illuminates when a
signal is given.
Problem: The gate doesn't open (or close) though the
motors are running.
Solutions: Make sure that the motor is running in the
right direction, and make sure the Manual Release
mechanism has fully engaged the worm screw drive.
Problem: The gate opens but does not close.
Solutions: Make sure you have selected the desired
operating mode.
Verify that the reversing devices are working properly.
The LED DL2 should be illuminated. If it is not
illuminated, then one of your reversing devices is
preventing the gate from responding to your signal.
Check the devices.
Problem: The gate does not fully open (or close).
Solutions: Reprogram the control panel.
Check to see that there are no obstructions in the path of
the gate or that the hinges are not binding.
Problem: The operator doesn't work smoothly and
the gate jerks as it opens and closes.
Solutions: Make sure the Manual Release mechanism
has fully engaged the worm screw operation of the
operator.
Make sure that a flexible gate leaf is not the problem. If
the gate leaf flexes, then stiffen the gate or use a slower
operator.
