Automation Options
Enables the resident to view the visitor from a designated monitor
in the house. The system requires a coaxial cable between the monitor
and the keypad, installed with the primary cable runs from the house.
An automatic multifunction 24-hour 7-day time
clock can be used to control free-entry or even open the gates during
a specific
time of day and days of the week, and close gates, at night,
for example. This device can also control vendor entry codes to specific
days, or specific
times of day, for example: Monday through Friday, 0700 to 1800.
Installed in a convenient location
in the house, such as the kitchen, the control panel provides
a Sound-Alert, Status indicator lamp, Open-hold open Switch,
Free-entry Switch
independent of house
telephone
system. Additional RCP’s can be wired in series and located anywhere
in the house.
FAAC brand hydraulic gate operators, specifically models 750
and model 400 offer the best balance of aesthetics, reliability
and continuos duty for the cost.

| Model 400: linear piston/cylinder with motor and pump all in
one-unit mounts between the post and backside of the gates. These
units are installed near the bottom of the gates and the operator
is visible. |

Model 750: Rotary actuator installed below finished grade, functions
as a power hinge, with hydraulic pumps installed in a remotely
located control cabinet. All copper tube hydraulic plumbing and
control wiring below ground, provides for a clean installation,
not visible from either side of gates. |
I prefer the FAAC model 750 to the model 400 for
the following reasons:
- The working components are
installed below ground, and attach only to the bottom corner
of the gates. The entry
gates look the same inside & out. There is nothing accessible
to an intruder, or can be tampered with. The working components
of the model 750 rotary actuator are separate: the drive unit
(under the gate) and the power unit (in the control panel). The
drive unit, mostly stainless steel, is connected by hydraulic
tubing only, and no electrical connections or motors are below
ground. The power unit, secure in the control cabinet, is protected
from the elements, is essentially a sealed system, and accumulates
little or no condensed moisture.
- The model 400 linear actuator
combines electric motor, pump, valve body, piston & cylinder all in one unit.
It is installed on the secure side of the gates. (I mount them
near the bottom) The unit is visible, connected to both the gate
and the gatepost. Installation parameters require some modifications
to existing gate columns, to allow clearance for this type of
operator, usually at additional cost. A problem inherent in the
design of any linear actuator is when the piston moves through
the cylinder, it displaces oil and air in the tank. When reversing,
it draws outside air back into the tank. It is the outside air,
with all it’s moisture from humidity, rain or irrigation,
etc. that condenses in the tank and can cause problems. This
is kept in check with annual maintenance. |
