For a system with automatic addressing, expanders and keypads belong to the same numbering
sequence. For example, expanders and keypads are automatically numbered 01, 02, 03, etc., by the
controller in the order in which they are detected, for example, its relevant location to controller. In this
configuration, zones are allocated to each input expander.
Automatically addressed expanders are not supported by SPC41xx.
16.6.2 XBUS Refresh
The X-Bus Refresh utility performs a discovery of the current status of the X-Bus and displays the
current X-Bus configuration.
To refresh the X-Bus status:
1. Scroll to XBUS REFRESH.
2. Press SELECT.
The number of online keypads is displayed.
3. Press the right soft key on the keypad after each display to view expanders, zones and offline
items.
4. Press this key again to exit.
Refresh
makes no changes to the system, but is useful for detecting system faults, such as loose
connections, or inactive expanders, before performing a
Reconfigure
.
16.6.3 Reconfigure
NOTICE: A reconfigure only applies to wired zones on an expander. Wireless zones on an
expander and controller zones will not be brought online after a reconfigure. To bring controller
zones online, you must apply a zone type other than ‘Unused’ using the zones menu on the
keypad or web browser.
If the system has a mixture of expander types (with and without rotary switches) then the system can
only be automatically reconfigured. If the system has all expanders with rotary switches, the system
can still be automatically reconfigured and the system will ignore the rotary switches and auto
addresses all the expanders on the system.
It is recommended that you perform a
Refresh
before a
Reconfigure
.
To reconfigure keypads/expanders:
1. Scroll to RECONFIGURE.
2. Press SELECT.
The number of online keypads is displayed.
3. Press NEXT.
The number of online expanders is displayed.
4. Press NEXT
