Specification of BRD01 – MAG STANDARD VEHICLE LOOP DETECTOR

In any card access system, the reader will trigger a barrier gate
to open upon flashing a valid card. But how to allow the barrier gate to
automatically close after the car has passed through?

With the enhanced EWI loop detector (BRD05). If the loop coil having
any changes of the inductance due to loop coil cable condition, road
surface changes or any other unforeseen interference, EWI loop detector
is safe and secure to function.

The loop detector is reliable and cannot be tempered easily as the main control is hidden inside the barrier gate.

The loop detector is reliable and cannot be tampered with easily, as
the main control is typically hidden inside the barrier gate.

Avoid arm hitting a car

A loop detector can also help to prevent the gates from closing
too soon. When the vehicle is passing through, it will break the
circuit and tell the gate to remain open, preventing it from closing on
the car. When the barrier arm is descending, BRD05 will trigger the arm
to auto-reverse if it detects another vehicle entering to avoid hitting
it.

No human shall pass through barrier gate lane

BRD05 is a metal detector and cannot detect humans. BRD05 will
not be able to trigger the barrier arm to descend if a human walk past
through. To avoid this problem, another BRD01 can be installed to ensure
there is a vehicle before activating the reader to accept card reading.

Cannot go in from the opposite direction

In some cases where there is no card access system, BRD05 can
be used to automatically trigger the barrier gate to open upon detecting
the presence of any vehicle. By installing the loop coil in 1
direction, you can effectively block any vehicle trying to enter from
the other side.
