Delta supplies
standard and custom control circuitry
to operate single or multiple barricade
systems. We
also use programmable logic controllers
(PLC) for special applications to time
and coordinate gates, signal early
warning systems, safety interlocks
and multiple operating modes. International
voltages are available.

 Junction
Box and Control Circuitry top
This photograph shows a typical two barricade
control circuit with an integral motor
starter, electrical disconnect and step
down transformer.
We build control circuits to project
requirements from the simple to highly
complex integrated systems controlling
multiple barricade systems. International
voltages are available. |
 Hydraulic
Power Unit – Skid Mounted
for Big Equipment top
This is the top of the line, heavy duty,
patented Delta Power Unit. We
rack and stack valves, flow controls
and accumulators to meet our client’s
applications for speed of operation,
number of barricades to be controlled
and the number of power off cycles required.
The pump is supplied with an integral
tank, sight gage and level switch. Options
include hand pump and oil heater. The
unit shown is a two barricade system
pump.

Pictured is the patented Delta Beta pump,
a scaled-down version of the Delta Power
Unit. It
is used for our medium to small barricades,
depending on site conditions, barricade

DC Powered Pump top
Universal voltage DC powered versions
(Model H8050)
of these pumps are available for remote
locations or infrequently operated
barricades. They feature
long battery life, low amperage trickle
charging and solar panel charging.

 Vehicle
Loop Detectors top
Recommending
its use with all Delta and most other
vehicle access control systems, Delta
Scientific’s NP Series Digital
Loop Detectors are programmed to prevent
a closing signal when power is resumed. NP
Series Loop Detectors are directly interchangeable
with most other brands as a plug-in replacement.
These loop detectors provide customers
with a safety detector that can prevent
accidents which occur when power
outages cause vehicle access control
systems to reset their logic. The
3446 NP Series incorporates an advanced
micro-controller that combines a
powerful digital computer and the
latest and most advanced inductive
vehicle loop technology to give high-test
reliability and accuracy when measuring,
counting or detecting vehicles.
This ability helps avoid unexpected
gate operations such as the raising
or lowering of gate arms, sliding gate
operation, motorized teeth and barricade
actuation. Delta
highly suggests and is seeing a wider
application of vehicle loop detectors
to suppress the operation of heavy
gates and vehicle barricades to prevent
accidental closings or raisings when
authorized vehicles move through vehicle
access control systems.
Typical digital loop detectors hold
a gate open until the last part of
a vehicle has passed the closing loop,
located beyond the gate. The
detector then gives a pulse on departure,
instructing the gate to close after
the vehicle has passed. Oftentimes,
after power outages, the entire system
needs to be reset. The NP Series negates
this problem.
Delta NP Series Loop Detectors provide
input voltages of 24 VAC, 24 VDC, 120
VAC and 230 VAC. |

|
3546-3NP |
FEATURES:
Configured not to generate a
pulse when initial power up or
power resumption occurs. This
can avoid unexpectd gate operations
(raising or lowering of gate
arms, sliding gate operation,
motorized teeth and barricade
actuation). Recommended for use
with ALL of DELTA' S vehicle
access control equipment and
most other manufacturers. This
is a direct replacement of a
Delta model 3546-3 where power
resumption safety is desired.
