[1] Bypass Zones takes you immediately to bypassing
zones. Use the [<] [>] to select the zones to be
bypassed and press the [
✱
] key to select the zone. A
“
✱
” will appear beside the zone label to indicate the
zone will be bypassed when the partition is armed.
A zone search routine allows the user to find the desired
zone to bypass by entering in the first letter of the zone
to search for, and pressing one of the [<][>] keys. The
[<] key will search for the first zone on the partition that
begins with the letter selected. The [>] key will search
for the next zone on the partition that begins with the
letter selected.
The letters of the alphabet have been divided up among
the 1 to 9 number keys on the keypad.

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.
[2] 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.
[3] Recall Bypasses 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.
[4] Previous Menu takes you back to the “Enter Code to
Arm System”.
When the PC4020 is programmed, the ability to bypass
certain zones may be eliminated. In this case, the “
✱
”
indicator 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 PC4020 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.

To view partition troubles from a global keypad, enter a
valid access code and select a partition. If (1) “For Options”
is selected the user will be prompted with the message
KEYPAD LOANED TO
(Partition Label)
Once the message has cleared, press [
✱
][2] to view the
trouble on that partition.
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. When DC
Inhibit Arm is enabled the panel will check the condition of
the batteries on the system (main panel, PC4204 and
PC4820) when an access code is entered. If during this
check the battery shows a low voltage condition the arming
will be inhibited. The LCD will display the message "Fail To
Arm... Battery Trouble" when this occurs.
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.
