INTRODUCTION
The use of any power source other than a PC4204 to
repower the COMBUS will result in a system
malfunction.
The PC4216 low current module provides 16 separate
outputs. Each output may be programmed to operate under
the control of 1 of 35 options as listed in the programmable
options section of the installation manual. Up to 8 other
PC4216’s may be used to provide outputs for graphic
annunciator or similar devices for the maximum of 128
zones. The PC4216 connects to the COMBUS with four
wires. A maximum of 9 PC4216’s may be connected to a
system. The PC4216 may be installed in the main cabinet or
in other cabinet options and is shipped as a board only.
The PC4020 includes the capability of driving a serial
printer using a PC4400 RS232 output module. The PC4400
connects to the COMBUS with four wires. The printer may
be located up to 200 feet (60 meters) away from the
module. The PC4400 is shipped as a board only.
The PC4820 Access Control Module provides the ability to
have 2 access card readers and 2 doors interfaced to the
PC4020KT. There can be up to 16 access control modules
enrolled on the system to make a total of 32 zones that can
be interfaced to the alarm system.
The PC4020 is a highly flexible and versatile control
which will enable the installer to meet the most
demanding security requirements. The heart of the
system is the main control panel, designated the
PC4020, which is connected to other system elements
using common 4 conductor unshielded station wire. The
main panel processes signal information and
communicating with the monitoring station. The main
panel is capable of supervising 16 zones, any of which
may be defined for fire or burglary applications and also
manages up to eight separate and fully independent
partitions, assigning zones and their controlling keypads
in accordance with installer programming.
The basic 16 zone capability of the PC4020 can be
expanded using either PC4108, PC4116 or PC4164
modules which provide 8, 16 or 64 zones of additional
inputs respectively up to a system maximum of 128
zones. The PC4108 and PC4116 are designed for use
within any of the cabinets and are shipped as PC boards
only. The PC4164 is designed to be placed inside the
supplied cabinet.
Programming and system operation are carried out using
the LCD4500 liquid crystal display keypad. The
LCD4500 connects at any point in the system to the four
wire communication bus or “COMBUS”, its specific
identification being determined automatically in the
process of installing it. A maximum of 16 LCD4500
keypads may be used on any one system regardless of
size.
The PC4204 relay output module is available for
installations requiring additional power beyond the 500
mA supplied by the PC4020 main panel. This module
comprises a 12 volt DC power supply of 1.5 Amp
capacity and four 12 volt relays with form C contacts
which will provide switched outputs under any of the 35
options available in the list of programmable outputs. The
PC4204 connects to the COMBUS via four wires as with
other system elements. It requires a 16 -18 volt, 40 VA
transformer and a 12 volt battery. Up to 16 PC4204
modules may be installed on any one system. The
PC4204 is shipped as a PC board only.
