d. Daily battery capacity test.
For Australian operation, if the daily battery capacity test is enabled, a 40 minute
battery test will be done when the FIP sends a "system test" command to the RDU.
This is typically at 9 a.m. each day
For New Zealand operation, if enabled, a 40 minute battery test will be done when
the FIP initiates a "charger inhibit period". If the daily battery capacity test is
disabled, a request from the FIP to initiate a charger inhibit period is ignored. The
time of day that the test starts depends on the type of FIP but is typically at the start
of the auto test period at the FIP. For New Zealand operation, if the 40 minute
battery test fails, the test is terminated and a fault is signalled for the remainder of the
40 minute period, after which the fault automatically clears.
WARNING - older versions of RDU hardware must have the battery test resistors
R52, R53 removed from the MAF board if this test is enabled.
4. Charger fault monitor
If enabled, a fault is signalled when the charger is high or low. A charger low condition
must be present continuously for 60 seconds before a fault is signalled. Charger low is
ignored for 30 minutes after a battery capacity test. If the charger fault monitoring
parameter is disabled, a charger fault will still be indicated on the charger LED and in
system fault recall, but no fault is signalled.
NOTE - when a new or flat battery is connected to the panel, a battery low fault is likely to be
present until the battery charges up. An operator command is available that allows such
faults to be ignored for a 24 hour period, to give the battery time to charge.
6.4.4.11 Keys Enable
Each key on the keypad may be enabled or disabled for each of four operating states.
A use for this feature might be to disable specific keys, such as External Bell Isol or Warning
System Isol, when they are not required, or to disable RESET and ISOL keys in FF mode so
that the user cannot reset or isolate the alarms. Another use is for an NDU to have selected
keys enabled when the door is closed.
The four operating states and the default key enablements are:
1
- FF mode with door open - default all keys enabled
2 - FF mode with door closed - default all keys disabled
3 - Non FF mode with door open - default all keys enabled
4 - Non FF mode with door closed - default all keys disabled
"FF mode" refers to when the FF alarm list is being displayed. When FF mode is active, the
principal keys used are those enclosed in the red border on the keypad - ACK, RESET,
ISOL, NEXT, PREV, WARNING SYS ISOL, and EXTERNAL BELL ISOL.
Non-FF mode refers to operation when the FF alarm list is not being displayed.
When the panel is in program mode or has a database checksum error, all keys are
automatically enabled. Also, if the database write protect link is in the enable position then
the SET key, NUMERIC keys and CLEAR key are automatically enabled to allow entry to
program mode. For a Tandem LCD connection, all "remote" keys are automatically enabled.
Note that disabling a particular key does not prevent a particular function from being done
another way. For example, if the ISOL key is disabled a zone can still be isolated by
pressing the ZONE key from the base display and using the menu option. Enabling
RECALL, NEXT, PREV, CLEAR, ACK and NUMERIC keys and disabling ZONE, ISOL,
RESET, RELAY, TEST, ALARM TEST, and FAULT TEST keys allows recall of information
without allowing reset, isolate, test or programming functions.
