1. Overview
Congratulations on selecting a Nice gate
operator for automating your gate system. With
proper selection, system design, installation and
maintenance this operator should provide years
of reliable operation.
This manual covers the following Nice operator
models: 3501 with 1050 (see 1551 manual for 1050
board programming and controls available).
1.1 1050 Control Board
The 1050 main control board is housed in a
protective plastic enclosure that includes a 2-line
LCD, with 5 dedicated buttons and 3 buttons
for navigation of the setup, programming, and
information menus, as well as 3 buttons for open,
close, and stop. Connectors for power, inputs,
and output peripherals are arranged around the
edges of the board and clearly labeled. A plug-
in connector is provided for direct installation of
a Nice-brand receiver which can be controlled
by up to 1000 transmitters. A recessed RJ-11
jack offers a connection to an optional O-View
programmer and optional Bluetooth module that
can be programmed via PC. Connectors for other
Nice-brand plug in accessories include 2-wire
Bluebus, self-monitored photocells for entrapment
protection. Dry contact inputs are provided for
loop, probe, and photoelectric detectors, as
well as guard station and fi re department control
of gate opening and closing. Voltage outputs
(+12VDC and +24VDC) are also made available
to power safety and entrapment-prevention
devices, and a magnetic lock if required. On
board charge control circuitry delivers reliable
power to a backup battery (if installed) and the
unit is equipped with input for a solar panel for
self-powered installations.
The 1050 main control board accepts DC input
voltage ranging from 10VDC to 32VDC. A 2-line
LCD with dedicated buttons allows installer to
quickly program the 1050 when changes to its
factory-default settings need to be made. A real
time clock/calendar enables programming for
scheduled weekly or daily events like opening,
closing, or locking the gate. Gate opening and
closing speed, acceleration, soft-start settings,
and reversing speed may be set to factory
default settings, or individually programmed per
customized gate installation requirements. Built-
in current sensing enables inherent gate force
monitoring and limiting for safety and an on board
alarm indicates when two sequential obstructions
have been sensed in either direction. The “Learn”
function helps gate installer confi gure Nice 1050
control board semi-automatically for optimum
settings of gate opening and closing speeds,
with simple programmable adjustments to force
and speed settings that may be made with the
programming button on the control panel.

1.5 The installation of this product is not a “do-
it-yourself” project. A qualifi ed gate operator
installation company should be contacted
to install the gate operator to ensure a safe
and reliable installation. Since many aspects
of gate system installation are under the
control of the installer, it is the responsibility
of the property owner to ensure the installer
is qualifi ed to carry out the installation in a
safe and professional manner.
1.6 Consult local government agencies for
up-to-date rules and regulations as certain
municipalities have established licensing,
codes or regulations that regulate automated
gate system design and installation.
2. General Safety Information
A gate operator is only a component in a gate
system. The other parts of the gate system
can include the gate, the external entrapment
sensors, access controls, and vehicle detectors.
To have a gate system that provides safety,
security, and reliable operation it is essential these
components operate together as a system. It is
the responsibility of the system designer and/or
installer to ensure any safety or operational issues
have been addressed.
IMPORTANT SAFETY INSTRUCTIONS
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.
KEEPGATES PROPERLY MAINTAINED. Read
the user’s manual. Have a qualifi ed service
person make repairs to gate hardware.
7.
The entrance is for vehicles only. Pedestrians
must use separate entrance.
8. SAVE THESE INSTRUCTIONS.
WARNING
To reduce the risk of injury or death.

2.2 Vehicular Traffi c Only
This automatic gate operator is not designed nor
is it intended for pedestrian traffi c. Vehicular gate
operators must by their nature be powerful to
function reliably. This power can cause injury or
death. Accordingly, direct all pedestrian traffi c to
a separate walk-through gate.
2.3 Install This Gate Operator Only When:
a. The operator is appropriate for the
construction of the gate and the usage Class
of the gate,
b. All openings of a horizontal slide gate are
guarded or screened from the bottom of the
gate to a minimum of 1.83 m (6 ft) above the
ground to prevent a 57.2 mm (2-1/4 inch)
diameter sphere from passing through the
openings anywhere in the gate, and the
portion of the adjacent fence that the gate
covers in the open position,
c. All exposed pinch points are eliminated or
guarded, and
d. Guarding is supplied for exposed rollers.
2.4 The operator is intended for installation only
on gates used for vehicles. Pedestrians must
be supplied with a separate access opening.
The pedestrian access opening shall be
designed to promote pedestrian usage.
Locate the gate such that persons will not
come in contact with the vehicular gate during
the entire path of travel of the vehicular gate.
2.5 The gate must be installed in a location so
that enough clearance is supplied between
the gate and adjacent structures when
opening and closing to reduce entrapment
risk. Swinging gates shall not open into public
access areas
2.6
The gate must be properly installed and work
freely in both directions prior to gate operator
installation. Don't change operator settings
to compensate for an improperly installed,
improperly functioning, or damaged gate.
2.7
Permanently mounted controls intended for
user activation must be located at least 1.83
m (6 ft) away from any moving part of the gate
and where the user is prevented from reaching
over, under, around or through the gate to
operate the controls. Exception: Emergency
access controls only accessible by authorized
personnel (e.g. fire, police, EMS) may be
placed at any location in the line-of-sight of
the gate.
2.8
A Stop and/or Reset button must be located
in the line-of-sight of the gate. Activation of
the reset control shall not cause the operator
to start.
2.9
A minimum of two (2) WARNING SIGNS shall
be installed, in the area of the gate. Each
placard is to be visible by persons located
on the side of the gate on which the placard
is installed.
2.10
When utilizing a Nice 1050 board, a
maximum of 10 entrapment protection
devices may be connected.
2.11
For gate operators utilizing a non-contact
sensor (Photo Eye):
a.
See instructions on the placement of non-
contact sensors for each type of application,
b.
Care shall be exercised to reduce the risk
of nuisance tripping, such as when a vehicle,
trips the sensor while the gate is still moving,
and
c.
One or more non-contact sensors shall
be located where the risk of entrapment or
obstruction exists, such as the perimeter
reachable by a moving gate or barrier.

8
2.12 For a gate operator utilizing a contact
sensor (Edge):
a. One or more contact sensors shall be
located where the risk of entrapment or
obstruction exists, such as at the leading
edge, trailing edge, and postmounted both
inside and outside of a vehicular horizontal
slide gate.
b. A hardwired contact sensor shall be
located and its wiring arranged so that the
communication between the sensor and the
gate operator is not subjected to mechanical
damage.
c. A wireless device such as one that transmits
radio frequency (RF) signals to the gate
operator for entrapment protection functions
shall be located where the transmission of
the signals are not obstructed or impeded
by building structures, natural landscaping
or similar obstruction. A wireless device
shall function under the intended end-use
conditions.
d. One or more contact sensors shall be
located on the inside and outside leading
edge of a swing gate. Additionally, if the
bottom edge of a swing gate is greater than
152 mm (6 in) but less than 406 mm (16 in)
above the ground at any point in its arc of
travel, one or more contact sensors shall be
located on the bottom edge.
3.
Use of Vehicle Detectors
Use of vehicle detectors (loop detectors) is strongly
encouraged to prevent damage to vehicles
caused by gates closing on them. This is not
considered to be a safety item as vehicle detectors
cannot provide protection to pedestrians. In some
situations, photoelectric devices may be used as
vehicle detectors, but should be wired accordingly.
4. Gate Construction and Safety
Gate construction plays a very important role in
ensuring the safety of any automated gate system.
The standard for gate construction is ASTM F2200.
Below are key areas to address safety in gate
design. For complete information consult the

5. Maintenance of Gate Systems
To keep your automated gate system performing
both safely and reliably it is important to ensure
that the components of that system are functioning
properly. At least monthly:
5.1
Disconnect the gate operator and manually
move the gate through its range of travel.
Note any squeaks from rollers or hinges or
areas of binding. The gate should travel
smoothly and quietly throughout its range.
If it does not, contact a gate professional to
correct the problem.
5.2
Reconnect the gate operator and perform the
following tests:
5.2.1
With the gate opening, block any photo
eyes and/or depress any safety edges used
to protect the open direction. The gate
should stop, or, stop and reverse.
5.2.2
With the gate closing, block any photo
eyes and/or depress any safety edges used
to protect the close direction. The gate
should stop, or, stop and reverse.
5.2.3
Using a suitable obstruction in the path of
the gate (a solid, immovable object), run the
gate in the open direction until it contacts
the obstruction. The gate should stop and
reverse.
5.2.4
Using a suitable obstruction in the path of
the gate (a solid, immovable object), run the
gate in the close direction until it contacts
the obstruction. The gate should stop, or,
stop and reverse.
