For example, to search for the first zone that begins with
the letter “R”, press the [6] key three times until the letter
“R” is displayed on the keypad between the “< >”.
Press the [>] key, the first zone that begins with the letter
“R” will then be displayed.
[1] Clear Bypasses - Removes all bypasses from all the
zones in your partition and then takes you to
bypassing zones. None of the zones will have a “
✱
”
beside them.
[2] Recall Bypasses - Selecting this will bypass all the
same zones that were selected the last time zones
were bypassed. This is for users that are always
bypassing the same zones.
[3] Previous Menu - takes you back to the “Enter Code
to Arm System”.
When the PC4000 is programmed, the ability to
bypass certain zones may be eliminated. In this case,
the “
✱
” message for those zones will not come on in
response to the bypass command. Zone bypasses are
automatically cancelled when the panel is disarmed.
The installer can choose by partition if a code must be
entered with [
✱
]+[1] to bypass zones. Only the zones
assigned to the same partition of the system as the
keypad can be bypassed. Only certain types of access
codes can be used to bypass (See [
✱
][5]).
NOTE: At no time can any armed zone be bypassed.
Trouble Display
[
✱
]+[2]
The PC4000 continuously monitors a number of possible
trouble conditions. If one of these conditions occurs, the
keypad “TROUBLE” indicator will light and the audible
indication will sound (two short beeps every 10
seconds). When the [#] key is pressed the audible
indication will stop, but the trouble indicator light will
remain ON until the trouble is cleared. Trouble
conditions can also be transmitted to the monitoring
station. Press the [
✱
] then [2] keys to display the types
of trouble conditions.

Press [#] to return to “READY”.
Battery Trouble...
A battery trouble will be displayed
and can be reported if the battery is 11.3 volts or less,
disconnected or the battery fuse fails. Battery voltage is
checked once every 4 minutes, so the battery trouble
may not restore instantly when the battery is restored.
Initiating a bell/comm test will check the battery voltage.
AC Trouble... There is no audible annunciation on AC
power failure. The system “Trouble” light will come ON
but the audible indication will not sound until there is
a low battery condition. Transmission delay can be
programmed for 000 to 255 minutes.
Aux Supply Troub... An Aux trouble is generated if the
aux fuse on the main panel opens, or if the Aux or SW
Aux terminals are overloaded.
TLM Trouble... A telephone line trouble is generated
when the line voltage drops below 3 volts for more
than 30 seconds. A keypad trouble is generated when
the system is disarmed and if selected, a local alarm
sounds when the panel is armed.
FTC Trouble... If the digital communicator is
unsuccessful in communicating with the monitoring
station after 10 attempts, a Fail to Communicate trouble
is generated. If a later attempt to communicate is
successful the trouble is cleared.
Bell Cct Trouble... If the bell fuse opens or the bell
circuit is open, a keypad trouble and a Bell Circuit
trouble transmission are generated.
Fire Trouble... If a FIRE loop is open circuit, a keypad
trouble and a Fire Loop trouble transmission are
generated. A trouble on the FIRE loop will
unconditionally initiate an audible and visual (trouble
light) indication on the keypad. This means that even if
any other previous trouble has been silenced, a FIRE
loop trouble will restart the keypad buzzer.
Loss of Time... When the PC4000 is powered up, the
internal time of day clock needs to be set to the correct
time. This trouble is cleared when an attempt is made to
reset the internal time of day clock. See “System Master
Codes” for resetting the time of day clock.
Module Com Fault... The panel has lost
communications with a module and cannot recover it.
Check to see if the module is connected properly, then
do a system reset. See “Diagnostics” in the
Programming Manual to determine which module is not
communicating.
COMBUS Low Pwr... Modules are not getting enough
voltage from the COMBUS. Check for proper connection
of COMBUS, or the COMBUS needs to be repowered.
See 4204 modules and the 4204 PGM COMBUS power
option for supplying voltage to the COMBUS. See
“Diagnostics” in the Programming Manual to determine
which module has low voltage.
Internal Fault... a problem has occurred with the
COMBUS microprocessors. If this trouble occurs, check
connections to the COMBUS and do a system reset.
