HARACTERISTICS
The FAAC 422 Operator is an automatic gate operator
for a swinging gate leaf. It can accommodate a gate leaf
of up to 900 lb (410 kg) and up to 10 ft (3 m) in length.
The 422 Operator can be used to swing the gate leaf
inward or outward. Most versions provide hydraulic
locking in at least one position, either opened or closed,
de
pending on how it was ordered.
The hydraulic lock is a service device rather than a
security device. Additional, external locks are
rec
ommended under the following conditions:
•
You are installing the Model 422 SB
•
The length of the gate leaf is 12 ft or more
•
The installation requires tight security
•
The site is subject to vandalism
•
The site is subject to strong or very gusty wind
•
You are installing a solid face gate
For its protection, the single-phase, bidirectional motor
shuts off automatically if its operating temperature
reaches 212 deg F (100 deg C). Also for the protection
and proper operation of the 422 Operator, each gate
leaf on which it is installed must have a fixed positive
stop in both the opened and closed positions.
The 422 Operator also includes a key-operated Manual
Release mechanism and two bypass valves that precisely
control the force applied to the gate leaf through the
400 Operator.
The Manual Release mechanism is a key-operated device
that disengages (or engages) the hydraulic system of
the 422 Operator. When the hydraulic system is
disengaged, you can open and close the gate leaf by
hand. Such manual operation of the gate is necessary
during installation and useful dur
ing power failures.
The two bypass valves are located beneath the locking
cap. You need to adjust the bypass valves to meet the
safety standards of FAAC International, Inc. The
standards state that the gate leaf should 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 more
complete protection for people and property.
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.
Note: The 455 D Control Panel provides inputs for
opening and closing reversing devises. FAAC strongly
recommends the use of such devises, like photocells or
other non-contact sensors.
Note: A reversing device is required for a U.L.
recognized installation.
Caution: Failure of an opening reversing device cause
the gate to lock in the closed position and requires the
use of the Manual Release key.

The following logics are available on the 455 D:
•
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 the pause phase
interrupts the pause time; a second command
during closing reopens the gate. A maintained
open command will hold the gate open.
•
S (security): The security mode is like A logic
except that a second command during opening
immediately closes the gate. A maintained
open command will not hold the gate open.
•
E (semi-automatic): 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. A third
command then closes the gate.
•
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. A third
command then reverses the previous motion of
the gate.
•
B (manned, pulsed): This mode is designed for
guard station use and requires a three-button
switch (pulsed) to open, close, and stop the
gate.
•
C (manned and constant): This mode requires
constant pressure switches. One to open and
one to close. No pressure on a switch stops the
gate.
