15.0 Troubleshooting Guide
15.1 Keypad Problems
Entry Error: Please Re-enter will
display on keypad. A three beep error
tone will sound continuously.
a) Two or more keypads share the same
address.
b) The DS7430 or DS7433 is installed in
the wrong pins.
a) Install keypad jumper properly in back of
keypads.
b) Be sure the DS7430 or DS7433 is installed
properly.
Symptom Probable Cause Possible Solution
Keypad displays Not Programmed,
See Instal Guide, sounder is on and
the keypad does not operate.
Keypad displays Ready to arm,
partition 1 when using only one
partition.
Keypad displays System Fault,
sounder is on, and the keypad does
not operate.
Keypad alpha display is locked up,
but the keys still function.
Can’t read back history with # 89
input.
In history, the Read-back for the A, B,
and C keys shows:
A = Fire
B = Emergency
C = Panic
But, the Central Station
transmissions display B as Silent
Panic and C as Audible Panic.
Can not perform a zone test (#81).
a) The keypad not addressed properly.
b) The keypad is not programmed
properly.
c) Keypads 11-15 are not properly
configured.
The keypad is programmed as a Master
keypad.
a) Keypad wiring error.
b) Keypad(s) assigned to wrong or non-
existent partition.
c) The microprocessor isn’t running.
The keypad is enabled, but as an LED
keypad.
a) Entering from Master keypad.
b) Not using a PIN with test authority.
Formats display information regarding the
B and C keys differently.
In Contact ID: A = Fire
B = Silent Panic
C = Audible Panic
In SIA: A = Fire
B = Emergency
C = Panic
a) Entering from a Master keypad.
b) Not using a PIN with test authority.
a) Install the keypad jumper properly in the back of
the keypad.
b) Check keypad programming addresses 3131-
3138.
c) Check keypad addresses 11-15. System will
only see keypads on the options bus.
Enter the program mode at the keypad and input
the correct sequence to re-enable it as an alpha
keypad. Care must be taken, since there will be no
visual feedback to verify programming until the
keypad is properly enabled.
a) First enter Single Partition Mode.
b) Use a PIN with test authority.
Discrepancy exists in the definition of these keys in
the two formats. Whatever the keys are
programmed for in the panel, that is what will be
sent.
a) Zone test is not available from a Master keypad.
b) Use a PIN with test authority.
Master keypads can only be used on multi-partition
systems. Program the keypad as a standard
keypad.
a) Check wiring.
b) Assign the keypad(s) to correct partition. If none
of the keypads are correctly assigned, re-enable
keypad 1 by shorting the program contacts in
the lower right corner of the main panel board.
This will force program mode and assign
keypad 1 as alpha, non-master to partition 1.
c) Disconnect battery and any aux. power load. If
the microprocessor has shut down, aux. power
will read approx. 11.5 VDC. If the EEProm chip
has been field-replaced, power down AC and
battery, and check for bent or mis-inserted pins;
Otherwise, replace the panel.
