Delete the device information from within the control unit. Each type of device has its
own “delete” command in the Installer menu.
Reset the bus address on the device to zero.
If a bus device is damaged and you suspect it is faulty then you can use the Installer menu
to temporarily disable the device. The control unit will ignore any input from the device
while it is disabled, and not send any output commands to the device. When the time
comes to replace the damaged device then the Installer menu provides a “Replace”
command that you can use to swap out the damaged unit for a new one, of the same type,
retaining all the device information from the old unit.
Note: Do not physically replace bus devices without using the Disable or Replace
commands. If you do not use these commands first you will cause a bus tamper.
Bus Device Addresses
The control unit reports the addresses of bus devices as two groups of characters,
separated by a “-“:
An-dd
A =
One or more letters showing the device type: PAN=panel, K=keypad, W=Wired
Expander, R=Radio Expander.
n =
Bus number. In an i-onEX control unit the bus number is always 1. Connections
directly to the control unit do not show a bus number.
dd =
Bus device number. This can be any number 01 to 95.
In an i-on160EX there can only be a total of 45 devices
In an i-on50EX there can only be a total of 20 devices.
In an i-on30EX there can be a total of 10 devices.
Expanders always have bus device numbers in the range 01 to 45. Keypads always have
bus device numbers in the range 51 to 95.
Figure 3 shows an example of how the control unit in a small system might address each
device attached to the bus. The system has two 10-zone expanders and three keypads.
Each device has one address.

Bus Device Addressing Example
The EXP-R30 is a bus device that uses more than one device address. In Figure 4 the
second expander on the bus is an EXP-R30. The EXP-R30 always takes three
consecutive bus device numbers. In Figure 4 the control unit gives this one device the
numbers R1-02, R1-03 and R1-04. In the Installer menu the keypad display shows only
“R1-02” but also adds the characters “(R30)” at the end of the line as a reminder.
