Section 10: System Programming
10.1 AC/DC Power Options
Ref # [000200]
The following options are used to determine the power settings
for the system. Press [*] to toggle each option on or off.
Power Up Shunt: If enabled, all zones will be inactive during
the first two minutes of power up to prevent causing false
alarms (default=Yes).
NOTE: Do not disable the Power Up Shunt option if AML devices
are used.
AC Trouble Displayed: If enabled, the system keypads will
display an AC trouble. If disabled, the AC Trouble will not be
included in the system trouble indications (default=Yes).
AC Frequency 60 Hz: Enable this feature if the AC cycles at
60Hz; disable it for a 50Hz cycle. The standard for North
America is 60 Hz (Default=Yes).
AC Inhibits Arming: If enabled, the system cannot be armed
when an AC trouble condition is present on the main panel,
PC4204/PC4204CX, PC4702, PC4820 or PC4850. If dis
-
abled, the system can be armed with the presence of an AC
trouble (Default=No).
DC Inhibits Arming: If enabled, the system will not arm when
a low battery condition is present on the alarm control panel, the
PC4204/PC4204CX, PC4702, PC4820 or the PC4850. If dis
-
abled, the system can be armed with the presence of an DC trou-
ble (Default = No).
NOTE: This feature does not apply to wireless devices. If enabled,
a battery trouble will not inhibit arming. The control panel and
PC4204/PC4204CX/PC4702/PC4820/PC4850 modules will only
communicate and log to the event buffer three low battery events
per 24 hour period (reset at midnight).
10.2 Bell Circuit Supervision
Ref#: [00020300] Bell Cut-off
Ref#: [000200] System (Bell) Options
The Bell Cut-off time will determine how long the fire/burg bell
outputs will be active when an alarm occurs. Valid entries are 000-
255 minutes (Default setting = 004 minutes).
The following system toggle options items will determine how
the fire/burg bell outputs will operate.
Bell Shutdown: If enabled, the burg bell outputs will not acti-
vate for a zone that has reached the swinger shutdown limit, if
programmed. If disabled, a zone alarm will always activate
the burg bell outputs (default=Yes).
Fire Timeout: If enabled, the fire bell outputs will follow the
bell time-out. If disabled, the fire bell outputs will remain
active until a valid access code is entered to silence the alarm
(default=Yes).
Bell Delay Timer*: After an audible burglary alarm has
occurred, the system will delay sounding the bells for the
amount of time programmed in this timer. Valid entries are
from 000 - 255 minutes. If 000 is programmed, there will be
no delay before the bells sound (Default = 000).
For more information regarding the bell output programming,
please see Section
11.1 ”Main Panel Outputs’. For information on
bell circuit wiring, please see 2.12 ”Bell Output Wiring (BELL+
and BELL-)’.
10.3 Clock Options
Set System Time and Date
The System time and date can be programmed by the user and
thus are not accessible in the Installers Programming mode. For
instructions on programming the time and date, see the Instruc
-
tion Manual ’Setting the Time and Date’.
Daylight Savings
Ref #: [00020303]
Program the date on which daylight savings time will begin. The
month, day and week are required (where MM = 01-12; D = 1-7
Sunday-Saturday; W = 1-5).
To program daylight savings time to start on the first Sunday in
April, enter [0411]. At 2 a.m. on the programmed day, the time
will automatically adjust to 3 a.m. daylight savings time. All
scheduled events that would have occurred between the hours of 2
and 3 a.m. will not occur for this day.
Standard Time
Ref #: [00020304]
Program the date on which standard time will begin. The month,
day and week are required (where MM = 01-12; D = 1-7 Sunday-
Saturday; W = 1-5).
To program standard time to start on the last Sunday in October,
enter [1015]. (Sometimes, there are five Sundays in a month. If
there are not 5 Sundays in the month, the change to standard time
will occur on the 4th Sunday.)
At 2 a.m. on the programmed day, the time will automatically
adjust to 1 a.m. standard time. Any scheduled events between 1
and 2 a.m. on this day will occur twice.
System Clock Options
Ref #: [000200]
The following system options pertain to the system clock. Press
[*] to toggle each option either on or off.
Military Time: If enabled, the clock will display 24 hour
time (military time) and date will show as MM/DD/YY. If
disabled, the clock will display 12 hour time—with an ’a’ for
a.m. or ’p’ for p.m.—and the date will show as Month/DD/
YY. The printed time and date also follows this option
(Default=No).
Crystal Time: If enabled, the timebase will be the internal
crystal oscillator. If disabled, the timebase will be the AC
power input. The crystal oscillator should be used for applica
-
tions with a less reliable AC power source (Default=No).
Clock Adjust
Ref #: [00020308]
This option is to compensate for any timebase inaccuracy. The
panel will replace the last minute of each day with the number of
seconds programmed in this section.
For example, if the panel seems to lose nine seconds per day, pro-
gram this section as [051]. Valid entries are 000-255 seconds. The
default value is [060].
NOTE: Do not schedule events to occur during the clock adjust time.
10.4 Event Messages
The following event messages can be modified from their default
settings to suit the users needs. To enter new labels, enter each
character as outlined in Section 5.4 ’Zone Programming – Zone
Labels’.
These messages will only appear if the ’Special Messages’ toggle
option is enabled by the end user/system administrator, by entering
[*][6][access code][0][2].
The zone tamper and zone fault messages will be displayed regard-
less of the [*][6] Special Messages option setting.
