Kentec Analogue Panels – 400mA Loop Current

Syncro V5.91 – Syncro AS V5.23 firmware update details
The following problems have been resolved in V5.91 / AS V5.23 firmware release
Cause and Effect events are passed to the panel serial port
This amendment allows Disablement and Test Mode Cause and Effect events to be
monitored and displayed on a Guide Graphics system, or reported on any other third
party monitoring equipment that utilises the panel serial port communications
Alarm Contact – disablement mode
The alarm contact on the panel can be configured to operate whenever a
disablement is active on the Syncro panel. To configure this mode of operation, the
Alarm Contact must have no output attributes selected AND must not be in any
cause and effect entries.
In previous versions of firmware that supported this feature, the cause and effect
entry validation did not work correctly and therefore it was possible that the output
continued to operate on disablements – even when in cause and effects.
This is resolved in this version
“Zone” cause and effect and non-fire events on networked panels
One of the ways to write cause and effects is to select a “Zone” as the cause, to
operate outputs in the effect. In this case, a fire in the selected zone will start the
cause and effect processing.
It was found on a networked system that, if non-fire event (technical alarm / fault
etc) in the same zone as the fire event was cleared during the fire process, then this
caused the zone cause and effect to also clear.
This scenario only applies to systems where “normally active” plant, such as fans
running, dampers open etc are monitored by the panel and are stopped/closed under
a fire event.
In this version, the panel now only clears the cause and effect when all the fire
events in the active zone are cleared
Edit Device Menu - some device types missing in the Change Device menu
The Hochiki ALG-E photoelectric device was missing from the change device menu.
All Hochiki devices have been added to the Add Device menu and all detection device
types are included in the Change Device menu
Bypass delays upon operation of “non-fire” events in cause and effects
When an input that is not configured as a fire event, but has the “Delay Bypass”
attribute selected is included in a cause and effect to control delayed outputs, the
outputs will now operate with no delay.
Previous versions of firmware required the input type to be a fire event in order for
the delay to be bypassed.
NOTE: This only applies if the non-fire input activated is the first input in an “OR”
cause and effect. If a “non-bypass delay” input is operated first then the cause and
effect is “true” and the outputs will operate after the delay period. Subsequent
operation of any input will not re-process the cause and effect and therefore will not
bypass the delays.
Apollo Discovery Base Sounder Beacon – tone control and volume setting
The Apollo Discovery Base Sounder Beacon now may be configured to operate with
different tones for different event types (configured in Loop Explorer V4.90 “Edit
Panel Settings” screen).
We also support the ability to configure a global volume setting and also to
individually configure the device volume using the magnetic wand. By using a menu

Syncro V5.91 – Syncro AS V5.23 firmware update details
option you can prime the panel ready for setting the volume, then apply the wand
next to the sounder to switch it on. Holding the wand next to the sounder will adjust
the sounder to the required volume. When the correct audibility volume has been
set, remove the wand and re-apply momentarily to switch off the sounder. Press the
“Enter” key on the panel to apply the new volume to memory.
Hochiki Detectors - Calibration halted for disabled devices
When disabled Hochiki detection devices were enabled during the daily calibration
routine, it was possible to occasionally get invalid fire analogue values calculated
which on very rare occasions could lead to a fire event. This process has been
amended to prevent such a situation.
Hochiki CHQ-S / CHQ-DIMM – Additional input verification checks
The CHQ-DIMM / CHQ-S generates an interrupt whenever an input is activated. The
control panel services the interrupt and checks the input state then reports the
In the rare situation where the panel does not receive an interrupt from the device,
yet determines that an input has been operated, the panel will perform additional
verification checks on the device before reporting the input activated.
Under most conditions these additional checks will not affect the system performance
as the interrupt is normally present, but this further reduces the possibility of a false
activation in the situation when an interrupt has not been sent from this device type.
Improved network card data handling
The network card data processing has additional detection facilities to trap and
resolve corrupted data without adversely affecting the panel or network reliability. In
earlier firmware versions there was the possibility that the network card could drop
offline as the result of attempting to process invalid or corrupted data.
Syncro / Syncro Focus – Buzzer silence problem
A problem was identified whereby it was not possible to silence the buzzers of
networked panels from Syncro Focus repeaters – even if they are configured in Loop
Explorer to do so.
This is resolved in this version
Hochiki CHQ-POM extended output delay
When this device is configured as a “Output normally on” output with the “Remove
on reset” attribute selected, the output is removed for a minimum of 5 seconds, to
allow sufficient time for beam units to reset
If updating the firmware in networked panels, all panels should be updated to the
same version.
If the network contains a mixture of Syncro and Syncro AS panels, then V5.91
should be installed in the Syncro panels and V5.23 in the AS panels.
