Overview
Reconfiguration step-by-step
Replacement process
When replacing a generic device on an AK-SM 800 system, issues are seen which leads to additional
time spent during this replacement process.
Typical issues are:
1. Duplicate addresses
2. Uncfg messages shown
3. *Mismatch* shown
4. Loss of programmed settings
The following guideline explains how to address and/or avoid such issues by following a standard
replacement method. The guide also describes known pitfalls which could lead to above issues.
It is the precondition for this guideline that a system is fully configured and operational with at least
one case controller (generic device).
Replace controller
and connect device
Update SM 800
Firmware
Install required EDF
files and Device List
Reconfigure SM
800 for new device
Step 1: Replace controller
Before making the physical replacement of
the device, ensure that unintended alarms
are not sent to monitoring centers. The field
communication line must be disconnected and
the new device reconfigured, before the alarm
system will function properly again for the given
device.
Replace the controller and reconnect the field
communication line from the System Manager to
the new device.
Configure the device with the correct field bus
address and application.
Step 3: Install required EDF files
and Device List
Please refer to the User Guide
BC316842192932en-00010
All changes to the device.ls3 file and EDF files
require a unit reset.
Step 2: Update SM 800 firmware
It is advised to always use the latest SM 800
firmware in order to take advantage of features
and support for latest devices.

1. Confirm scan status:
Confirm current Scan Status for existing configuration. Address 10 shows an existing AK-CC 550
MODBUS.
Step 4: Reconfigure SM 800 for new device
The recommended method to reconfiguring a
newly added device as replacement of another
is to use the manual configuration screens rather
than the assisted layout wizard.
If you are replacing the controller with a
controller of the same type and software version,
no EDF related changes to the system manager is
required.
