DS9400 Series | Release Notes for Firmware V2.07 | 7.0
.
Manual Battery/NAC Test during AC Fail:
Manually initiating a battery test (Test Menu,
Option 4) when AC has failed will now correctly
display the current battery voltage. However, if
a user at the control panel requests a manual
battery test within five seconds after AC power
fails, the system may shut down until AC power
returns. Manual battery test while AC is present
will correctly test and report the battery voltage,
and a manual test when AC power has failed
will report the current battery voltage.
Improved Smoke Power Control
Monitoring: When AC power fails, the control
panel draws from the batteries to maintain
operation. When the battery voltage falls below
20 volts, the control panel will shut down.
Panels with date codes after 9935 will power
down, and control panels modified according to
Technical Service Note P/N: 42363 will enter a
low power idle state. To ensure that all attached
smoke detectors are correctly powered up after a
shutdown, the control panel will wait for the
smoke power voltage to stabilize before applying
smoke power and continuing operation.
To ensure that power is applied cleanly to the
smoke detectors, smoke power is now turned off
if it falls below 15 volts and not restored until it
reaches 20 volts.
Improved Battery Monitoring: Processing of
restored batteries has been improved so that a
RESET operation is never required.
Local Only Points Implemented: Central
station reporting is now correctly suppressed for
points programmed for "Local Only" operation.
Response Time After Transients: Firmware
prior to version 2.02 may allow an extended
alarm response time after an electrical transient
(e.g. lightning). In the worst case, an alarm
occurring 10 minutes after a transient would
take 10 minutes to be registered. After 10
minutes, the response time returns to normal.
With version 2.02 firmware, response time
correctly remains at 500 ms for fast response, or
at the desired programmed response time for
programmed response points, regardless of
possible prior transients on the line. This issue
was observed during recent lab testing of the
control panel and has not been reported from
actual installations, but upgrading the firmware
in installed control panels to version 2.02 will
assure proper response time under all
circumstances.
Bosch Security Systems | 8/06 | 36925V
Fixed Items Since Firmware Version 1.08
Programming Access: Firmware version 2.02
corrects a configuration problem found in
control panels with prior firmware that
improperly allows programming access to all
valid user codes and not only "Level
1/Maximum" codes.
Phone Troubles: On a small number of
DS9400 units, when using firmware prior to
version 2.02, an interaction between normal
hardware variations and firmware timing has
been observed to cause the control panel to
falsely report a disconnected phone line. On the
small number of control panels with the affected
hardware, the fault causes occasional phone
trouble reports that are followed by an
immediate restoral report. Replacing the ROM
to upgrade the firmware to version 2.02 corrects
the problem with no need for hardware
modifications.
User Interface Delay: Under unusual
circumstances, the user interface in firmware
prior to 2.02 would stop accepting input for up
to three minutes if remote keypads were present
on a system. This no longer occurs in version
2.02.
Relay Module Operation, Disabling: Remote
relay modules may fail to activate properly
under some circumstances in firmware versions
prior to 2.02. Additionally, attempting to disable
remote relays has caused the control panel to
stop operating and freeze the display. The relay
modules operate and can be disabled as
expected in version 2.02. Note that when a
remote relay module is disabled, all eight relays
on the module are disabled with one operation.
Auto Silence Clarification: When configuring
points and NACs for auto silence, the setting on
each NAC to enable or disable the auto silence
feature is not implemented. Setting the timer to
a value other than zero (0) enables the auto
silence feature. Any NAC that can be silenced
(based on which inputs are in alarm) will be
silenced when the auto silence timer completes,
regardless of the setting selected for the
individual NACs. Additionally, a NAC activated
by a non-latching point will not automatically
turn off when the point restores if there is any
other off-normal condition on the control panel.
It must be manually reset.
