i-on160 The System Bus

Page 19

y Carrying out a bus scan does not change the bus configuration. Note that

on large systems a bus scan may take some minutes.

y If you are confident that the control unit has already learned all the devices

on the bus you do not have to carry out a bus scan (but it may be a useful

check).

If you have temporarily removed a bus device you can reconnect it to the

bus, provided that you carry out a bus scan and do not change its bus

address.

y If, as a result of a bus scan, the control unit offers to re-configure the bus

(and you accept) then new devices will be added to the system only if they

already have a bus address. Missing devices will be removed from the

system (along with all details of the partitions they belong to, and any zone

information).

y A bus re-configure is not saved until you leave Installer Menu. If the control

unit loses power before leaving Installer Menu then the bus re-configure

does not take effect.

Zone Numbering

When reporting alarms to an ARC using CID or SIA protocols the control unit

reports each detector as a zone number. The i-on160EX numbers zones in a

continuous range from 001 to 159. The zone numbers are independent of the

physical connection points for each detector. The process of assigning zone

numbers to detector connection points is called “mapping”.

Mapping Zones to Device Connections

The control unit assigns blocks of zone numbers to each bus device

sequentially.

1. The connection points on the control unit pcb take zone numbers 001 to 009

(for FSL wiring) or 001 to 005 (for CC wiring).

2. Each bus device takes a sequential block of zone numbers, running on from

the previous bus device.

Figure 7 shows the zone numbers used by the example system in Figure 5.
