HARACTERISTICS
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 14
ft (4.3 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:
∗
It is a solid-faced gate.
∗
The length of the gate leaf is 6 ft (2 m) or longer.
∗
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.
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 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.
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.
Built-in security and anti-crushing measures of the 412
Operator include a key-operated Manual Release
mechanism and a torque adjustment mechanism that
precisely controls the force transmitted to the gate leaf
through the 412 Operator.
The Manual Release mechanism is a key-operated device
that disengages (or engages) the worm screw drive of
the 412 Operator. When the drive is disengaged, you
can open and close the gate leaf by hand. Such manual
operation of the gate is necessary during installation
and useful during power failures.
The torque of the 412 Operator is set during Basic
Programming of the 455 D Control Panel. (see page 20
for Basic Programming). FAAC recommends that the
gate leaf stop if it encounters a force of more than
about 33 lb (15 kg).
Reversing devices (such as inductive loops and
photocells) should be installed to provide non-contact
reversing operation.

REPARE
THE
G
ATE
Before you install the 412 Operator, you need to prepare
the gate itself for the operator. Be sure to do the
following three things:
Make sure that the gate structure is solidly built. Add
reinforcing crosspieces if necessary to the gate leaves.
Make sure that the gate moves smoothly on its hinges
without excessive friction by swinging it opened and
closed by hand. If necessary, lubricate all the gate's
moving parts.
Provide positive stops for the gate leaves in the fully
opened and fully closed positions (see Figure 3).

NSTRUCTIONS
Installing the 412 Operator involves preparing the gate,
installing the operator(s), installing the control panel,
setting the torque adjustments on 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.
