PYTHAGORAS 3
12.4 Selection of Operating Mode
IR Optical Module 100 and IR Optical Module 160 barriers can operate in two different modes.
-
“AND GATE”
Mode:
The alarm is activated when there is a simultaneous interruption of the 4 infrared beams
created by the two optical modules,
-
“
OR GATE
” Mode:
The alarm is activated when there is a simultaneous interruption of the two infrared beams
emitted by the upper optical module or the two infrared beams emitted by the lower optical
module.
When the signal becomes unstable due to the effects of snow or fog it is also possible to
activate a third operating mode, or
“
BYPASS
”. In this mode it will not generate any alarms if
unfavourable environmental conditions are detected (signal unstable for longer than 3
seconds). If this mode is disabled the alarm will be generated if the signal is unstable for longer
than for 3 seconds..
The selection of this operating mode is by using dip switch n°4 and n°5 on the receiver:
