IRBO=IRBC
Configures the opening beam to act as a closing beam while the gates are
closing. This allows one set of beams to be used across the line of the driveway
up to where the gates open.
IR beam alarms
While the gate is fully closed, 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
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 beams
are broken, and for a period of 30
seconds thereafter. This time is
fixed
If this alarm is used, it is
recommended that TWO
parallel closing beams are
used to reduce the chance of
false triggering
!
