Problems with Command Centers
Symptom
Diagnosis
Remedy
Command centers show
erratic behavior.
For example, the pip that
confirms you pressed a
key "echoes."
More than one command center
has the same supervised
address.
Entering a supervised address in more than one command
center causes erratic behavior.
Use a supervised address in one command center only.
Supervised addresses support only one command center
per address.
Data connections (yellow and
green wires) on one or more
command centers are reversed,
or only one wire is connected.
Check to be sure that the yellow and green data wires are
correctly connected at all command centers.
NO AUTHORITY
displays at command
center when you enter
your passcode to perform
a function.
Check the
User Interface section of the program to be sure the function is enabled for
Authority Level assigned to the passcode in the
Passcode Work sheet section of the program.
Check the
Passcode Worksheet section of the program to be certain the passcode is
assigned to the area where you are attempting to perform the function.
Check the
Passcode Worksheet section of the program to see if the passcode is restricted by
a user window.
Check the
Area Parameters section of the program to be certain the area you are attempting
to perform the function in is turned on.
Battery and Power Reports
You can program the panel to transmit both
battery and AC power status reports. See the
D9000/D7000 Series Program Entry Guide (74-
07695-000). If battery or AC power reports are a
problem check the following.
1.
Check to be sure you are not overloading the
panel's power supply. Review the
Power
Outputs section and Overloaded Power
Supply in this section.
2.
Verify that there is at least 16.5 VAC on
terminals 1 and 2.
3.
The outlet the transformer is plugged into
should meter between 110 VAC and 120
VAC.
4.
Verify that the output for the transformer
connected to terminals 1 and 2 is rated for
16.5 VAC and at least 40 VA.
5.
Disconnect the transformer from terminals 1
and 2 and meter the battery at terminals 3
and 4. A fully charged battery should show
13.8 volts.
6.
Make sure the battery is a 12 V sealed lead
acid type. It should be rated at 7 Ah or
greater, depending on the NFPA
classification of the installation.
7.
If it takes longer than 60 seconds to detect a
missing battery, make sure you have good
earth ground connection. Also check that
there are no external devices that may be
inducing voltage.
Watchdog Reset Reports
The panel sends a WATCHDOG RESET report
whenever the panel's CPU (Central Processing
Unit) is interrupted and has to start its normal
operating sequence over. The on-board buzzer
sounds briefly during the WATCHDOG reset. The
panel returns to normal operation immediately
after resetting.
The most common cause of CPU interruption and
WATCHDOG RESET reports is static discharge to
the panel. Static discharges may also corrupt the
panel's program. The D9412/D9112 displays a
PARAM FAIL message at the Command Centers
and sends PARM CKSUM FAIL report if the
program is corrupted.
Shorting terminals 3, 6, 7, 8, or 24, or connector
J4 to ground may also cause a WATCHDOG
RESET. Remove the short to continue normal
operation.
A single isolated WATCHDOG RESET report
does not mean you have to replace the panel. If
you experience frequent reports, contact
Radionics Customer Service for help.
Touch Terminal 10 first: If the on-board buzzer
sounds briefly when you first touch the panel,
you're discharging any static charge you may be
carrying to the panel. The panel may generate
WATCHDOG RESET and/or PARAM FAIL events.
Always touch terminal 10, the panel's earth
ground connection, before beginning work on the
panel.
