Step 3: Bus Line Installations

ProSYS Plus supports up to 4 separate, independent RISCO bus lines. If one bus
line ever experiences a problem that interrupts data flow (such as being cut or
shorted), the other RISCO bus lines will continue operating normally.

Bus Line Wiring

On the main panel PCB, the 4 wires of each RISCO bus line (red, black, yellow,
green) connect to the respective screw terminals on the terminal block as follows:
Bus screw terminal
AUX RED
COM BLK
BUS YEL
BUS GRN

Describing Bus Devices

All peripheral devices (bus detectors, keypads, sirens) as well as expansion modules
(Single-Zone Expanders, 8-Zone Expanders, 16-Zone Expanders, Wireless
Expanders, Power Supply Expanders, Bus Zone Expanders, Output Expanders) that
connect and communicate to the main panel via bus line are all referred to as
bus-connected devices, or "bus devices." Bus devices fall under categories
pertaining to zones, outputs, power supplies, wired keypads and sirens.
NOTE: Even though zone expanders (single-zone, 8-zone, and 16-zone) connect
relay detectors and not bus detectors, they are bus devices.

Describing Bus Detectors and their Connection Options

Connect multiple bus detectors to RISCO bus lines via Bus Zone Expanders (BZEs),
which serve to expand the number of bus detectors and also enhance bus security
and performance. A smaller number of bus detectors can be connected individually
without connecting to Bus Zone Expanders – they are wired to a bus at the main
panel PCB (see Connecting Individual Bus Detectors to a Bus at the Main Panel,
page 21). For installation, refer to the packaged instructions supplied with the bus
detector.
