CHAPTER 2
OPERATION
2-1 INTRODUCTION
This chapter describes the PEGAsys system controls and in-
dicators located on the display panel. It also describes the
operating procedures and menu system.
2-2.1 Modes of Operation
There are two modes of PEGAsys system operation:
• In the default operation the panel will be set to latch all
alarm inputs on the system. The latching operation will not
allow the loop input devices to generate an "alarm off" sig-
nal that would possibly interrupt a discharge time delay
sequence. To return the panel to normal the "RESET" but-
ton will need to be pushed.
• The second mode of operation is non-latching. This option
can be enabled, using the PCS (
PEGAsys Configuration
Software) to define if a loop device input is to be non-latch-
ing. The non-latching operation will allow the loop input
devices to generate an "Alarm Off" signal to the panel. When
this signal is received the panel would interrupt the dis-
charge time delay sequence of operation. However, all out-
puts that had been activated previous to the "Alarm Off"
signal will remain on and latched until the panel is reset.
The advantage of offering a latching or non-latching operation
per loop input device, allows the installer/designer to custom-
ize the system. This allows the inter mixing of latching and non-
latching devices to protect critical areas where both type may
be specified
Figure 2-1. System Front Panel
When an Alarm returns to a normal state (Alarm Off), the buzzer
will sound in a pulsed fashion, the alarm off condition must be
acknowledged to silence the buzzer. During the Trouble Off
condition, the audible device provides no sound. The following
summarizes the buzzer operation:
• Alarm condition is indicated by a continuous ON signal,
• Alarm OFF is indicated by a ½ second ON ½ second OFF
signal,
• Trouble condition is indicated by a 1 second ON and 1 sec-
ond OFF continuous beeping,
Every individual change of status must be individually acknowl-
edged by pressing the ACKLDGE (acknowledge) pushbutton
to silence the Audible device.
2-2 CONTROLS AND INDICATORS
The control and indicators of the PEGAsys system are located
on the display panel, shown in Figure 2-1. The display panel is
mounted on top of the CCM. To gain access to the CCM, the
panel door must be open. Table 2-1 lists controls and indicators
for the display unit, giving name and functional description.
2-2.1 LCD Display
The display panel contains an 80-character (2X40) alphanu-
meric display. This LCD display is used to present system sta-
tus. In the procedure section of this chapter there will be several
