The 412 Compact 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 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:
•
Yours 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.
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.
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 450 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.
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 controlled by a
potentiometer located on the 450 MPS control panel.
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.
Operating Logic
The 412 Operator provides a Manual Release
mechanism for manually operating the gate. Manual
operation of the gate requires using a special key. The
450 MPS Control Panel provides logical operating
modes set on the control panel.
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.
