V5.4 Update – Hochiki ACB-E type support
From 1st July 2006, all Syncro EN54 (BSI
Kitemarked) control panels will be fitted
with firmware version 5.4.
One of the features supported by this firmware
version is full support for the Hochiki ACB-E
rate of rise heat detector.
The ACB-E heat detector has the same type
code as the older ATG-E fixed temperature
heat detector, which makes the device directly
compatible with older control panels.
In order to unlock the enhanced features of
the ACB-E detector, the control panel sends
additional commands to the heat detectors,
which only the ACB-E will respond to.
Syncro panel version 5.4 (and later) has
the facility to distinguish if the heat detector
is the ACB-E, by interrogating the device
with these additional commands.
If you are upgrading the Syncro firmware
from V5.2 or V5.3 and have ACB-E heat detectors
installed, it will be necessary to change
the configuration file to set these as ACB-E
devices. This is because they would have been
previously configured as ATG-E devices.
Before performing a firmware update, always
ensure that you have a copy of the site configuration
file. After updating the panel firmware to
V5.4, the ACB-E devices will be identified
as “Incorrect device type” faults,
as they will have been previously configured
as ATG-E fixed temperature devices.
Using Loop Explorer V4.5, open the site configuration
file and click on the address of the device
that has been identified as an incorrect device
type, then click on the “Change”
toolbar button. Select the ACB-E device type
instead of the ATG-E device for all addresses
reporting the incorrect device type.
Save this revised configuration then transfer
is configuration into the Syncro panel.
Note: When changing the
device type to the ACB-E, the default setting
is as a fixed temperature heat detector. Using
the sensor properties option in Loop Explorer,
it is possible to then re-define the device
to one of the rate of rise characteristics
Please also note that whilst Loop
Explorer V4.5 allows the ACB-E heat detector
to be connected to the Solo loop configuration,
the Solo and Solo 2 control panel only supports
this device as a ATG-E fixed temperature device.
