EXAMPLE:
The simplest event output control (EOC) equation would be:
Input = Output
A basic equation with one or more inputs would be :
Input Operator Input = Output
The system normally processes the EOC from left to right. However,
in equations with parenthesis the contents of the parenthesis are
executed first. Refer to the PCS user’s guide (76-014) for further
details.
2-8.1.1 LISTING EOC PROGRAMMING
The system's Event Output Control (EOC) program can be listed
out using either the owner's or installer's menu functions. To list the
systems EOC programming:
a.
Access
PEGAsys
system menus by:
(1) Press 0 (zero) key. Verify that the display reads:
PLEASE ENTER PASSWORD
(2) Type in the Level 1 or Level 2 password.
(3) Press the return
(
↵
) key. Verify that the display reads:
1:ISOLATE
2:LIST
3:SET
4:TEST
b.
Select the list EOC program by typing the function formula, 2-5-
1.
The system will then list all lines of the Event Output Control pro-
gramming on the LCD and any attached printer.
2-8.2
RTC Programming
The RTC program language permits outputs to be controlled by the
system’s real time clock. Outputs may be programmed to occur on
an hour, day, week and month time control basis. Alarm and Prealarm
threshold levels of all or individual detectors can be increased or de-
creased in sensitivity (within UL limits) under RTC control. The RTC
programming also provides the ability to control RCU relays, I/O
module Relays and smoke detector pre alarm and alarm set points.
The program consists of sequentially numbered lines each contain-
ing control object, control content, time, date and day of week. For
further details refer to the PCS user’s guide.
2-8.2.1 LISTING RTC PROGRAMMING
The RTC program can be listed out using either the owners or in-
stallers menu functions. To list the RTC programming:
a.
Access the
PEGAsys
system menus by:
(1) Press 0 (zero) key. Verify that the display reads:
PLEASE ENTER PASSWORD
(2) Type in the Level 1 or Level 2 password.
(3) Press the return (
↵
) key. Verify that the display reads:
1:ISOLATE
2:LIST
3:SET
4:TEST
b.
Select the list RTC program by typing the function formula, 2-5-
2.
The system will then list all lines of the Real Time Control program-
ming on the LCD and any attached printer.
2-8.2.2 ENABLE/DISABLE RTC PROGRAM LINE NUMBERS
Each line number of the RTC Program is automatically enabled when
entered into the system. Once a line number in the RTC Program
has been disabled using the procedure below, the line will be ignored
by the RTC Program until enabled. To enable a line number which
has been previously disabled follow the below procedure selecting
"ENABLE" in step b.
a.
Access the
PEGAsys
system menu’s by:
(1) Press 0 (zero) key. Verify that the display reads:
PLEASE ENTER PASSWORD
(2) Type in the Level 1 or Level 2 password.
b.
Select the set RTC program by typing the function formula, 3-4-
3. Verify the display reads:
1:ENABLE 2:DISABLE
c.
Select the desired choice and press return. Verify the display
reads:
RTC LINE NUMBER _ _ _
d.
Type the three digit line number and press the return key.
e.
You may continue with another RTC line or press backspace
key to cancel this function.

Types of Inputs and Outputs
The
PEGAsys
has various input and output devices/modules which
are discussed in the following paragraphs:
2-8.3.1 SYSTEM INPUTS
Devices which are classified as system inputs are smoke detectors,
heat detectors, and addressable contact monitors (alarm, trouble,
abort, waterflow, manual alarm, manual release, supervisory, and
normal). Refer to the PCS user’s (76-014) guide for further details.
2-8.3.2 REMOTE CONTROL UNIT (RCU)
The RCU input and output devices, which are connected to the RX/
TX loop(s), are specified in EOC programming by the devices four
digit address.
2-8.3.3 RX/TX LOOPS
The system specifies the RX/TX loop controller using its loop num-
ber followed by three zeros (1000 for RX/TX 1) in single loop sys-
tems and (1000 - 8000) in multi-loop systems. The specifier (1000
-8000) will appear in cases when trouble conditions are present on a
particular RX/TX loop controller (i.e., a PC Line Short on RX/TX 1 -
would be displayed as "RX/TX PC Line Short Loop 1").
RX/TX loop (zone) alarms occur if a loop device alarm initiates under
one of the following conditions:
•
Failed communications between the CCM and RX/TX module
(Trouble Condition)
•
Failed RX/TX processor. (Trouble Condition)
•
Failed input circuit of RCU device.
An alarmed input device on the RX/TX (in FailSoft mode) can only
activate EOC programming if the RX/TX zone is used as a pro-
grammed input (ZA1=1000, ZA2=2000, ZA8 = 8000, etc.).
2-8.3.4 SYSTEM OUTPUTS
Devices which are classified as system outputs are CCM - sig-
nals and relays (programmable / non programmable); I/O mod-
ules - signal outputs, relay outputs, agent release outputs, release
