TC Input
•
The TC is a command generated by the anti-tampering unit to inform the barrier of the system's condition (armed or disarmed).
When present (disarmed system), the TC enables:
- viewing of the alarm memory
- blocking of the alarm relay, for less wear.
•
When it is not present (armed system), the TC command allows viewing of alarm events.
•
The TC command is considered to be present when the writing –12 V is indicated on the corresponding cable (Brown).
•
The TC command is considered to not be present when the writing 0 V is indicated on the corresponding cable (Brown), or when the
cable is not connected.
RX Programming
•
Each RX column is supplied with 2 jumpers that are used for
programming the operating mode.
•
INTEGRAL JUMPERS: POINT-TO-POINT BEAM MODE
An alarm is generated when a single beam is interrupted for at least
one second, or when 2 adjacent beams are interrupted for >0.1 sec.
•
YELLOW CUT JUMPER: ADJACENT BEAM MODE
An alarm is generated when 2 adjacent beams are interrupted for at
least >0.1 sec.
•
2 CUT JUMPERS: CROSSED BEAM MODE
An alarm is generated when a single beam is interrupted for at least
one second, or when 2 beams are interrupted for >0.1 sec.
WARNING: The range of crossed beams is typically 0.9 m and can
increase if the columns are installed in the presence of strong
environmental light.
TX Programming
• Each Tx column is supplied with 1 jumper for programming the
transmitted optical power as follows:
- integral jumper: reduced optical power
- cut jumper: maximum optical power
The following ranges are obtained according to the selected optical
power:

WARNING: - Detection faults or anomalies
may occur in the case of installation near
reflecting surfaces due to undesired optical
coupling. In many cases, the problem may
be solved by setting the curtain to reduced
optical power by leaving the Tx jumper intact.
Always check full functionality of the curtain
before completing installation
