the total number of active supervisory events. All cur-
rent supervisory conditions can be viewed on the dis-
play by pressing the <SCROLL> button.
3.
As each supervisory condition is cleared, the display
will read one (1) less active supervisory event until all
supervisories are clear. When all active supervisory
events have been cleared, the SUPERVISORY LED
will be extinguished, and the 80-character display will
show the Standby Message (e.g., "System Status Nor-
mal").
Note:
The system has the option to acknowledge both
supervisory and common troubles on a global ba-
sis. The panel, by default, will require that each
trouble be acknowledged individually. However, if
the installer wishes to enable this function, it can
be done by accessing the "set" menu option using
the CCM keypad. Refer to Table 2-4 for more in-
formation on stepping through the menus to en-
able and disable the Global Acknowledge function.
With global acknowledge, a total of thirty (30)
troubles can be acknowledged at one time.

Active Trouble Mode
The system enters trouble mode when it detects an ab-
normal condition that may prevent proper operation (e.g.,
loss of communications with a smoke detector) or when a
pre-alarm condition occurs. Refer to Appendix G for a com-
plete list of trouble conditions.
2-6.4.1
TROUBLE MODE INDICATIONS
The following indicates that the system is in its trouble mode
of operation.
•
The yellow TROUBLE LED will be flashing at a one
(1) second rate, and there will be a pulsing panel buzzer
at the CCP. This audible signal is distinctively different
than the alarm audible signal.
•
The 80-character display will cycle between all cur-
rently active troubles and pre-alarms. For example:
1080 TROUBLE _ _ Photoelectric _ Detector
_ _ _ 40 _ Character _ Location _ Message
Device Location (40 Characters)
Device Type
State
Trouble On
Pre-Alarm On
Device Address
(1001-1255)

TROUBLE MODE USER ACTION
The following steps should be performed when the sys-
tem is set into the trouble mode of operation:
1.
To silence the trouble audible signal, all current trouble
conditions must be acknowledged by pressing the
<ACKLDGE> button. This will silence the system
buzzer.
2.
When all trouble conditions have been acknowledged,
the 80-character display will read: XXX ACTIVE
TROUBLES REMAIN, with XXX representing the to-
tal number of active troubles. All current trouble condi-
tions can be viewed on the display by pressing the
<SCROLL> button.
Note:
Only the first 300 troubles (supervisory or com-
mon) will be displayed. Subsequent troubles or
supervisories will not be displayed, even if any, or
all 300 troubles clear. However, all of the active
troubles or supervisories will be processed and
entered into the event buffer. For a complete list-
ing of all troubles and supervisories over the initial
300, access the event buffer using the CCM key-
pad.
3.
As each trouble condition is cleared, the display will
read one (1) less active trouble until all troubles are
cleared. When all active troubles have been cleared,
the “TROUBLE” LED will be extinguished, and the 80-
character display will show the standby message (e.g.,
"System Status Normal").
Note:
The system has the option to acknowledge both
supervisory and common troubles on a global ba-
sis. The panel, by default, will require that each
trouble be acknowledged individually. However, if
the installer wishes to enable this function, it can
be done by accessing the "set" menu option using
the CCM keypad. Refer to Table 2-4 for more in-
formation on stepping through the menus to en-
able and disable the Global Acknowledge function.
With global acknowledge, a total of thirty (30)
troubles can be acknowledged at one time.

PRINTING OPERATION
In addition to the LCD display, the PEGAsys LV system
information can be viewed using the printer port of the
CCM. For detailed information pertaining to connecting an
RS-232 peripheral device, see Paragraph 7-14.
When the printer port is enabled and a serial printer is
attached, the system will print out all status change infor-
mation and any system information lists that the user would
request from the system using the integral keypad.

SYSTEM PROGRAMMING
The PEGAsys LV fire alarm system incorporates two
unique programming languages that are easy to under-
stand and use. These two versatile programming lan-
guages, Event Output Control (EOC) and Real-Time
Control (RTC), can accommodate most any fire alarm con-
trol logic application. The system is programmed using a
personal computer connected to the system via an inter-
face cable.
