Rs-485 Bus; Inputs; Programmable Output U1 (Positive); U2, U3, U4 Programmable Output (Open Collector) - CAME PXC08 Manuel D'installation

RS-485 BUS

For cabling the RS-485 bus refer to the section "Cabling RS-485 bus" .

INPUTS

For cabling the inputs refer to the section "Cabling inputs" .

PROGRAMMABLE OUTPUT U1 (positive)

m
A short circuit to GND with output active for a long time may lead to the protective resistor being broken .

U2, U3, U4 PROGRAMMABLE OUTPUT (Open Collector)

m
A short circuit at 12 V CC with output active for a long time may lead to the protective resistor being broken .
Non-self-powered siren
U1 is a (freely programmable) output that provides a positive when
it is active:
• U1 ON = 13 .8 V DC
• U1 OFF = not connected
It is factory-programmed as a TC to inhibit microwaves when the
system is off (U1 = OFF if at least one area is on or during exit times;
U1= ON if the system is totally off) .
The output is protected by a 100 ohm resistor .
It can also be used to control sirens or other loads .
U2, U3, U4 are (freely programmable) Open Collector type outputs
that provide a negative when they are active:
• U2, U3, U4 ON = 0 V DC
• U2, U3, U4 OFF = not connected
The outputs are protected by 100 ohm resistors .
If you want to control a relay with an Open Collector output (or relay
output), you will need to add a diode (1N4007) parallel to the relay
coil .
