Entry
System |

Gate
Operator |
There are several ways to access your gate.
|
|
These are the devices
that physically open the gate. Most operators are available in 120
volt AC or 12 volts DC for battery back up or solar operation. |
Digital
Access is a keypad that usually has a few entry codes that are
programmable by the user. These keypads typically do not have a
way of signaling that someone is at the gate. |
|
Swing
Operators come
in three varieties. |
| Telephone Access uses your
phone system to speak directly with a person at the gate and can open
the gate momentarily or hold it open for longer periods. These systems
offer complete control over the gate and have a digital keypad built
in. Timers are built into these systems that can open and close the
gate at specific times throughout the week. These systems allow you
to operate the gate from any landline or mobile telephone worldwide. |
|
Ram Arms are mounted directly
on the gate and use either a hydraulic piston or a jackscrew piston.
The control circuitry is usually installed in a separate box. |
| Radio Remotes are the same
as garage door openers. These are almost always used in conjunction
with other access systems or sometimes used as the only access control
on simpler systems. |
|
Swing Arm Operators are a larger
box that sits off to the side of the gate and uses an arm connected
to the gate. DoorKing brand operators have the arm located at bottom
of gate, which makes for a better looking installation. |
| Card Readers use magnetic encoded
cards similar to a credit card. Card readers recognize individual
users. Cards provide a high level of security because each user must
have their own card. |
|
Underground Operators are installed
below grade and offer a clean look. |
| Bar Code Readers read a bar
code that is attached directly to a vehicle that needs to access the
gate. |
|
Slide Gate Operators are used
more commercially or when road grades and site conditions prevent
the use of a swing gate. Slide gates have more safety issues than
swing gates and usually cost more to install. |
Loops |
|
Cantilever
Operators lift the gate into the air. These operators are used
sometimes in areas that are restricted in space or where road grades
prevent a conventional installation. |
| Loops are cut into asphalt
or concrete driveways or buried beneath gravel and earth driveways.
They are used to detect the presence of an automobile. Loops operate
like a metal detector and send a signal to the gate operator when
it detects a vehicle. |
|
Uninterruptible
Power Supplies |
Exit
Loops are used to provide a way of exiting the property and
are included in most installations. The loop is placed 20-100 feet
before the gate so that the gate is open or partially open as you
drive up to it. |
|
Uninterruptible power
supplies are available for complete system standby. These systems
are used when the utmost reliability is required and can run the system
for several days during a power outage. |
| Safety Loops are optionally
installed in front and behind the gate to prevent a gate from closing
on a vehicle that is in the path of the gate after the open time has
expired. |
