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. 
 
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.
