GATE OPERATOR INSTALLATION
PREINSTALLATION GUIDELINES:
Before starting any installation, consider the following guidelines:
• Install the gate system and gate in accordance with ASTM F220-02: Standard Specification for Automated Vehicular Gate
Construction. Install the gate system and gate in accordance with UL325 standards.
• Be sure the gate is properly installed and moves freely. Repair or replace worn or damaged gate hardware before installing the gate
operator.
• Install over-travel stops at both ends of the gate rail or track for all types of installations to help prevent the gate from derailing.
• Add safety devices such as warning signs, photo eyes, and reverse edges to help prevent injuries or death. Reduce all pinch points
and protect all entrapment positions.
• If pedestrian traffic will be present, provide a separate pedestrian walk gate clear from the path of the automatic gate.
• Loops and loop detectors are required to help prevent the gate from closing on vehicles. Loops do not protect pedestrian traffic.
• Select the proper gate operator for the installation. Consider the usage, capacity, gate size, gate weight, and needed features and
safety accessories.
GATE OPERATOR LOCATION:
Select a location for the gate operator to be installed prior to pouring the concrete pad. There are two ways to mount a slide
gate operator: the traditional front mount, or the rear mount method. Both methods have their advantages and will reliably
open the gate.
WARNING: Install over-travel stops at both ends of the gate rail or track for all types
of installations to help prevent the gate from derailing.
!
REAR MOUNT METHOD:
A rear mount installation places the operator at the back of the
gate and uses a double chain with an additional idler sprocket.
The advantages and disadvantages include:
Advantages:
• The chain is attached to the rear of the gate and is not
visible when the gate is closed.
• The operator is in the back away from the flow of traffic for
added safety.
• The operator is in the back allowing more room for tight
parking conditions.
Disadvantages:
• Twice as much chain is required for this type of application
= added expense.
• The application requires the use of an additional idler
sprocket = added expense.
FRONT MOUNT METHOD:
The front mount method places the operator up front near
the flow of traffic and uses a single chain across the length
of the gate. The advantages and disadvantages include:
Advantages:
• Less chain is required for the application saving money
and time.
• Does not require the use of an additional idler sprocket
saving money and time.
• Less room is needed for the application and allowing the
operator to be more accessible for service.
Disadvantages:
• The operator is up front near the flow of traffic allowing
for a vehicle to damage the operator more easily.
• The chain runs across the length of the gate allowing
visitors to see and possible tamper with it.
