WARNING
:.
The diagram is used for a preliminary estimation; for an accurate calculation, use the formula described above. However, it is
necessary to verify with a voltmeter, that the voltage measured on terminals of each device is not lower than the power supply voltage provided
by the control panel or by the additional power supply unit (0,7V–).
Using.an.alarm.system.cable.with.a.section.of.0,mm
for the serial line (LA LB) and 0,5mm
for power supply (+, –), the maximum distance of
peripherals.is:
1061/334-/335.readers:. 00m.
1061/434-/435.readers:.. 100m.
1061/05.keypad:..
50m
2.3.2 DATA BUS CABLE
For.the.bus.is.needed.a.4-wire.cable,.and.it.is.suggested.to.use.a.shielded.cable.for.alarm.system.4.x.0,mm
.+..x.0,5mm
,.in.order.to.have.
available.the.wire.pair.for.readers.tampers.contacts.
Bus.maximum.length.can.not.exceed.500m.
2.3.3 AUDIO CABLE
For.the.audio.line,.use.a.twisted.pair..The.audio.line.length.can.not.exceed.100m.
2.3.4 COEXISTENCE WITH MAINS CABLES
Bus.cable,.audio.bus.and.detectors.cables.can.not.be.laid.in.conduits.or.tubes.used.for.mains.cables.
