“GND”
– GND terminal.
“+28V-”
– Terminal for user supply voltage 28V to peripheral devices.
“Rel Fire”
– Output, relay, potentiial-free, the line’s status is not monitored.The output is
used to control devices in fire mode of the Control Panel.
“Rel Fault”
– Output, relay, potential-free, the line’s status is not monitored. The output is
used to control devices in fault condition of the Control Panel.
“+28V”
– Two terminals for supply v28V to peripheral devices.
“RS232/485”
– Terminals for connection of two-wire line of interface RS485 or three-wire
line for RS232. Switching between interfaces is done by changing position of a jumper on
the board. Interface RS232 is used for a connection with a
РС. RS485 is intended for a
connection between different Control Panels VIT01 (this functionality is not available in the
current version of the Control Panel). There is a jumper provided, which terminates the line
with resistor 120
upon mounting. This is necessary if the Control Panel is the endpoint of
the interface line. The interface requires both ends of the line to be terminated
with
resistors 120
.
“
┴
” – Terminal for connection of a third wire / shield / on the interface cable.
