signal outputs, city tie outputs and digital I/O module outputs; Loop
devices - addressable relay output module.
2-8.3.5 SYSTEM I/O MODULES
The Input/Output modules which the systems support are Signal
Outputs, Relay Outputs, Agent Release (agent & signal) outputs
and the City Tie output.
2-8.4
Addressing I/O Modules
The I/O modules include: Signal Audible, Relay Output, Agent
Release Output, City Tie output and the power supply module.
I/O modules refer to any I/O module which installs into the op-
tional I/O mother board with exception of the power supply
module(s). The I/O modules communicate with the CCM over
the I/O bus.
Each module has inputs or outputs which can be individually
addressed. The I/O address consists of two alphabetic and two
numeric characters which define the module type, address and
I/O circuit number. The I/O module address scheme is shown
below.
SG 1 : 3
Module Address (1-8),
See note 2.
I/O Circuit Number (1-4),

Module Type,
See note 3.
•
SG - Signal / Audible Output
•
RY - Relay Output
•
CT - City Tie Output
•
AR - Agent Release Output
•
RS - Release Signal Output
•
PS - Power Supply Monitor Module
NOTES:
1. The I/O modules vary in amount of inputs and outputs. Refer
to section one “component description” for thorough descrip-
tions of options.
2. The
PEGAsys
system can support a total of 16 I/O modules
for single loop and 23 I/O modules for multi-loop, 8 maximum of
any one type.
3. Power supply monitors only need an address, they have no
need for an output number.
The I/O module address is set using the three dip switches con-
tained on each PCB assembly, each module uses different num-
bered switches for module address assignment. The address
is set during the installation procedure by placing the switches
into the correct position. Refer to the appropriate figure in Ap-
pendix I for the particular module you are working with and the
addressing matrix. For a functional description of each module,
refer to Chapter 3.
The switches would be set for each type of module in order. For
example signal modules would be addressed 1 -8 if there were
eight in the system, relay modules would be addressed 1 - 8 if
there were eight in the system, and the same holds true for the
remaining modules with the only exception being the City Tie mod-
ule there can only be one of these modules in a system at any
time.
2-8.5
Registering I/O Module Assignments
I/O modules are registered into the system configuration through
the use of the PCS program. The installer would configure all
modules in the PCS program file and then upload this file to the
system which would then internally verify the existence of the speci-
fied modules. For further details on I/O module registration refer
to the PCS user’s guide.
Added RX/TX Modules in the multi-loop systems are automati-
cally registered by the CCM upon system power-up.
2-8.5.1 LISTING I/O MODULE ASSIGNMENT
All I/O modules which are programmed into the system con-
figuration may be listed out with the use of either the owners or
installers menu functions.
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.
(3) Press the return
(
↵
) key. Verify that the display reads:
1:ISOLATE
2:LIST
3:SET
4:TEST
b.
Select the list I/O address assignments by typing the func-
tion formula, 2-6-2.
The system will then list all of the registered I/O module ad-
dresses on the LCD and any attached printer.
2-8.6
Addressing RCUs
RCUs refer to all devices which connect and operate from the
RX/TX PC (power/communications) Line. These devices include
SmartOne smoke detectors, SmartOne heat detectors, addres-
sable contact input monitors, and addressable output contact
modules.
Each device has a three digit numeric address. This address is
stored in the non-volatile EEPROM memory of the device. The
system address is defined by the CCM by these three digits
and a fourth digit representing the RX/TX channel number.
There are three ways to address the RCU (Loop) devices.
•
The RCUs can be addressed using the Hand Held Pro-
grammer (P/N 74-200013-001). This optional unit provides
a convenient means of addressing RCUs without using the
CCM.
•
The user may address the devices individually on the sys-
tem by performing the procedure listed below.
To address RCUs using the “SET RCU Address” menu function
each unaddressed RCU’s must be connected to the RX/TX PC
line one at a time. Perform the following steps for each RCU:
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 2 password.
(3) Press the return (
↵
) key. Verify that the display reads:
