Nodes 5-8
햴
Ringnet Communications Connect the ringnet cable to the four terminals 1A to 2B. These terminals are used
for connecting the RKD node onto the ringnet – see the following connection diagram and cable type table.
햵
Power supply & current consumption To function correctly, the RKD requires 12Vdc which should be
supplied either directly from the controller power supply unit or from a remote power supply unit.
Current Consumption - Quiescent State: 150mA (backlight off), Maximum: 300mA.
햶
Inputs The RKD node has two on-board zone inputs. These inputs are monitored using dual EOL supervision as
wired in the following illustration:
.
햷
Output The RKD has 1 on-board 1Amp single pole changeover
relay, which can be assigned to any of the system outputs.
See Node Configure->Outputs in 3GS Programming for further
information.
햸
Tampers The RKD Node monitors both front and back tampers.
The front tamper is closed once the terminal block cover is
secured.
햹
Keys The keys are used for code entry, setting/arming and unsetting/disarming the system, and accessing the
menus detailed in the Software section. For further information on keys, see Typing Text in 3GS Programming.
IMPORTANT ! Never run Keypad wires alongside telephone wires, high
voltage wires, or transmitting antennae. Keypad wires should be wired
separately and not in the same cable with other devices (telephone, PIRs,
and so on). Do not use the keypad as a junction box for wiring power to
sensors. Install the keypad at human eye height (160-180 cm) for clear
display visibility.
