2-6 MODES OF OPERATION
The PEGAsys system has four modes of operation. Each mode
has different indications and action required. The following Para-
graphs describe each mode, indications and action if required.
2-6.1 Normal Standby Mode
This is the typical mode of the system. In this mode, no alarm,
trouble, or supervisory conditions exist in the system. The sys-
tem display will show the time, day of the week, and date. For
example:
SYSTEM STATUS NORMAL 11:06 AM_05-04-90
40_CHARACTER_CUSTOM_MESSAGE
The system provides an option which allows the System Status
Normal message to be replaced with a display of battery charg-
ing voltage and current for the system standby batteries. For
example:
PS01_26.0 V_0.10_A_ _ _ _ _11:06 AM_05-04-90
40_CHARACTER_CUSTOM_MESSAGE
The green AC POWER LED will be illuminated to indicate that
the system’s main power source is normal.
NOTE: In the Normal Standby Operation state, it is possible
for the 80-character display to show data other than
the time, day of date. This occurs when the system
menus are being accessed either locally or remotely
through one of its serial ports. This condition will be
indicated by the menu selections being displayed on
the display panel being illuminated.
In the Normal Standby Mode, no indicating LED’s will be illumi-
nated other than the “AC POWER.”
2-6.2 Active Alarm Mode
The system enters an alarm mode if a device (or devices) has
detected an alarm condition, such as smoke / heat above the
alarm threshold level. There are two types of alarms which can
occur:
Device Alarm
An alarm in which a device has communicated the alarm status
properly to the Central Control Panel, by providing the alarmed
device address for indication to the operator.
Zone Alarm
An alarm condition detected by one or several devices, but which
cannot be reported by a specific device due to a malfunction in
communications between the system and the alarmed device(s).
This is a redundant feature to increase system reliability and is
called Failsoft Mode.
NOTE: A device can signal a zone alarm to the system during
some communication failures.
2-6.2.1 ALARM MODE INDICATIONS
The following indicates the system is in its alarm mode of op-
eration.
a. The red “ALARM” LED will be illuminated and there will be
a continuous audible signal by the system buzzer at the
panel.
b. The 80-character display will cycle between all currently
active alarms. Example:
NOTE: If the alarm is a zone alarm, the Device Address “1000
- 8000” will be displayed depending on which RX/TX
module detects the zone alarm.
b. The outputs which have been previously programmed for
activation upon alarm by the specific devices will be turned
on. (Example: Signal audible signaling devices, control re-
lays for HVAC shutdown or elevator recall.)
2-6.2.2 ALARM MODE USER ACTION
The following steps should be performed when the system is
set into alarm.
a. Press the display panel’s ACKLDGE pushbutton to acknowl-
edge the displayed alarm condition. The 80-character dis-
play will continue to cycle between any remaining alarms
which have not been acknowledged. The “ACKNOWL-
EDGE” switch must be operated once for each alarm re-
ceived at the panel.
b. Once all current alarms have been acknowledged, the alarm
indicating circuits (audible devices) can be silenced by op-
erating the “SILENCE” switch.
c. After all of the current alarms have been acknowledged,
verify that the display reads: XXX ALARMS REMAIN. The
“XXX” representing the total of all active alarms. All active
alarms can be viewed on the display by pressing the scroll
pushbutton.
NOTE: The first 64 alarms will only be displayed. Subsequent
alarms over the initial 64 will not be displayed, even
when any or all of the first 64 alarms clear. However,
all alarms regardless of total will be processed in the
EOC. For a complete list of active alarms access the
event buffer menu using the CCM keypad.
d. Any subsequent alarms will cause the alarm audible cir-
cuits to resound. Each additional alarm must be acknowl-
edged before the alarm indicating circuits can be silenced.
e. When a device goes out of alarm, the display will indicate
the device address and an alarm off (AOF) message (non-
latching mode). Example:
1080 AOF_ _ _ _PHOTOELECTRIC DETECTOR
40_CHARACTER_LOCATION_MESSAGE
NOTE: If the alarm is a zone alarm, the address “1000-8000”
will be displayed, indicating that active device(s) in
failsoft mode in the zone have gone out of alarm.
f. Each device which goes out of alarm must be acknowl-
edged with the ACKLDGE pushbutton (non-latching).
