Runaway Reports to the Receiver
Using the D8128 or D8128A in place of the
D8128C OctoPOPIT Module may cause runaway
reports to the receiver on AC failure. Be sure to
replace all D8128 or D8128A OctoPOPITS with
the D8128C module.
Overloaded Power Supply
If the load on the panel's power supply exceeds
it's capacity, the panel follows a routine to protect
itself and the battery. It sends reports to the
Central Station at several points during this
routine.
Keep in mind that AC power remains at terminals
1 and 2 as you read the overload scenario below.
•
The panel is operating normally with a good
battery, AC is present at terminals 1 and 2,
and auxiliary power load is under 1.4A.
•
Combined load on terminals 3, 6, 7, 8, 24,
and 32, and connector J2 and J4 exceeds
and remains above 1.4A. Device failure or
premises wiring ground faults might cause
the increased load.
•
The panel begins drawing on the battery to
support the increased load. The yellow
charging status LED turns on.
•
The battery begins to drain. When voltage
drops to 12.1 volts, the panels sends a LOW
BATTERY report and turns on the red Low
Battery LED.
•
When the battery drops to 10.2 volts the
panel disconnects it to protect it from deep
discharge.
•
If AC is still present, the panel removes
power to terminals 3, 6, 7, 8, 24, and 32, and
connector J4 to protect its power supply. The
green operation monitor LED turns off, but
the panel is still operating.
•
The panel sends
BATTERY MISSING
,
PT
BUS TROUBLE
, and
SDI FAILURE
reports.
•
If a D928 module is connected to J2, it
begins sounding.
•
After approximately 60 seconds the panel
attempts to return to normal operation by
returning power to terminals 3, 6, 7, 8, 24,
and 32, and connector J4.
•
If the overload condition is still present, the
panel removes power.
•
The panel attempts to return to normal
operation approximately every 60 seconds.
•
The cause of the overload is removed.
Combined load on terminals 3, 6, 7, 8, 24,
and 32, and connectors J2 and J4 remains
below 1.4A.
•
With the overload removed, the panel returns
power to terminals 3, 6, 7, 8, 24, and 32, and
connector J4. The panel sends
PT BUS
RESTORAL
and
SDI RESTORAL
reports.
•
If a D928 module is connected to J2, it stops
sounding.
•
If the battery voltage is below 8.4 volts, the
panel does not reconnect it. You must
replace the battery.
•
When the battery reaches 13.7 volts the
panel sends a
BATTERY RESTORE
report
and turns off the red Low Battery LED.
•
When the battery reaches 13.9 volts the
panel turns off the yellow Charging Status
LED.
Service Walk Test
The Service Walk Test differs from the standard
Walk Test in that POPITs whose switches are set
for a point number not programmed in the panel
appear in the test.
Service Walk Test only available at Command
Centers with panel wide scope: See Command
Center in the D9000/D7000 Series Program
Entry Guide (74-07695-000) for a description of
Command Center scope.
Warning, fire and other 24-hour points do not
transmit reports during Service Walk Test!
The steps below outline a simple Service Walk
Test procedure. The flow chart on the next page
shows all the Service Walk Test options.
1.
Choose a Command Center with panel wide
scope to conduct the test. Be certain the
display shows the idle disarmed text.
2.
Press the MENU key to enter the Function
List. Press NEXT repeatedly until you reach
the
SERVICE WALK ? prompt. Press ENT.
3.
The display shows
### PTS TO TEST . Test
the first detection device.
4.
As you fault the detection devices, the
Command Center emits a brief tone and
displays the point text of the point tested for
60 seconds. After 60 seconds, the display
returns to the points to test message.
Extra Points display default text: If you
incorrectly set the switches on a POPIT to a
point number that is not in your program for
the panel, the default text for that point
number (
PT ###) displays when you fault the
point. The Program Record Sheet shows the
default text for all points.
Faulting the point a second time produces
the tone and displays the point text, but does
not reduce the
PTS TO TEST count.
