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)
Autoclose override time set to off: Total time to temporarily disable the
PIRAC feature is approximately three seconds
IR beam test
Automatically tests the safety beams before each gate cycle. (e.g. as required
by CE.)
In order for this feature to work, the power supply negative of beam
transmitter must be wired to the safe common terminal of the controller.
IRBO=IRBC
Configures the opening beam to act as a closing beam while the gates are
closing.
IR beam alarms
This feature allows the following alarms:
Ambush alarm
Activates an alarm if either the
opening or closing beams have
been continuously interrupted for
a predefined time. The alarm will
remain activated while the beams
are interrupted.
For example, if a would-be
intruder covers the beams so that
when the gate is opened, the gate
will stay open, the system will
detect this beam override taking
place and set off an alarm. Active
at all points of gate travel.
IR beam broken time
The time that the beams must be interrupted before the alarm is activated.
Break-in alarm
Activates an alarm if the closing
beam on the outside of the
property is interrupted. The
alarm remains activated while
the beam is broken, and for a
period of 30 seconds thereafter.
This time is fixed. Only active
when gate is fully closed.
If this alarm is used, it is
recommended that TWO
parallel closing beams are
used to reduce the chance
of false triggering.
