Two independent normally-closed inputs are provided for Opening and Closing
Safety Beams.
An interrupted closing beam will prevent the gates from closing and stop and
reverse the gates back to the open position if already opening. Vice-versa for an
opening beam.
Additional beam functionality is provided:
1. PIRAC Autoclose
The Passive-Infrared Autoclose
feature allows the gate to close
automatically, as soon as a vehicle
or pedestrian has passed through
the closing beam. This security
feature ensures that the gate stays
open for the minimum amount of
time possible.
If the Autoclose feature has been
enabled, the system will react in
the following way:
When the gate is triggered to
open and nothing moves
Outside Closing Beam
Inside Closing Beam
Opening Beam
IRBO = IRBC
(Combine inside Closing Beam with
Opening Beam = save on one beam)
FIGURE 80
through or interrupts the closing beam, the gate will open fully and stay
open for the period of time determined by the Autoclose TIMER
However, if the closing beam is interrupted at any stage, while the gate is
opening or open, the gate will close immediately after the closing beam is
cleared
If the Autoclose feature has not been enabled then the gate will remain
open indefinitely. To close the gate the closing beam must be interrupted
or the trigger button must be pressed.
2. Safe Output Status
Automatically tests the Safety Beams before each gate cycle. (E.g. as
required by CE and UL325)
In order for this feature to work, the power supply negative of the beam
transmitter must be wired to the Safe Com terminal of the controller.
The time taken for the gate to open again after it has come to a stop is
approximately three seconds
Example:
Autoclose Override time set to five seconds: Total time to temporarily
disable the PIRAC feature is approximately eight seconds
(5s + 3s = 8 seconds)
