CAUTION:
When used to power a module, the “RLY 1 COM”
terminal of the PC4204 must be connected to the
“RED COMBUS” terminal of the module only. The
positive (RED) conductor of the COMBUS must be
left unconnected to the module that is powered by
the PC4204. The “BLK COMBUS” of the module
should be run common to the negative (“BLK”) of
the COMBUS. Use of a power source other than the
PC4204 power supply module to supply additional
power to the PC4000 system is not recommended.
The COMBUS is a four conductor cable to which all
modules and keypads are connected in parallel.
Connections to the COMBUS do not have to be home-
run. For example if a storage building had an 8 zone
expander (PC4108) and a keypad (LCD4500) located
in it, the zone expander and keypad could be spliced
together and run back on a single 4 wire cable to the
nearest point on the COMBUS.
Mounting the Panel
Select a dry location close to an unswitched AC source,
a ground connection and a telephone connection for
mounting the Main Control Cabinet.
Remove the PC4000 printed circuit board, mounting
hardware, and keypad from the cardboard retainer
inside the large cabinet. Before attaching the cabinet to
the wall, press the five white nylon printed circuit board
mounting studs into the cabinet from the back.
Pull all cables into the cabinet and prepare them for
connection before mounting the circuit board to the
back of the cabinet. Press the circuit board down onto
the mounting studs.
There is room in the Main Control Cabinet (PC4001C)
for any two modules (PC4108, PC4116, PC4216 or
PC4400). Modules requiring power (AC and battery
PC4204) must be installed in the large Expander
Cabinet (PC4002C). This enclosure will accommodate
one module (PC4108, PC4116, PC4216 or PC4400) and
a powered output (PC4204) or any three modules. A
small Expander Cabinet (PC4003C) is available for a
single module that does not require external power.
Once the wiring is completed power the system up by
first connecting the battery followed by the AC
transformer. All LCD4500 keypads should display the
message ‘PC4000 DSC Ltd.’. Press a key on any
keypad that is to be assigned to Partition 1. The keypad
will beep and display the message ‘4500 Mod. #1' and
the keypad is automatically assigned to Partition 1.
Enroll every module to the system. Make sure you put
down the number of each module enrolled. Refer to the
Programming Manual for the required procedure.
When enrolling any PC4108 or PC4116 zone expander
module make sure to note the zones which you
assigned to the module.
This information is very important if it becomes
necessary to Add or Delete zones to or from a
Partition. Zones 1 through 16 are assigned to Partition
1 by default. This can be changed later in Installer
Programming.
In Book 2 (Programming Work Sheets) you will find a
four page System Overview section. Fill in the
information as each module is enrolled. These sheets
are designed to be left in the panel so if future service
is required, the location and assigned number of each
module will be readily available.
Once all modules are enrolled perform a diagnostics
check on the panel to determine if any problems are
present (See - DIAGNOSTICS).
Programming the System
The PC4000 has the capability to operate as 8 separate
alarm systems called Partitions. Dividing the panel into
Partitions will allow you to control access to specific
areas.
When the PC4000 is first powered up all zones on the
main board and User Codes are assigned to Partition 1.
If no other Partitions are required the entire system will
be considered Partition 1. This is important to keep in
mind as often in programming the panel will require you
to enter the Partition to program.
For example, when programming entry and exit times,
you must select the menu option ‘ADD/EDIT PAR’. The
keypad will then prompt you for the Partition to add or
edit. You must select Partition 1 for a system that has no
additional Partitions.
The factory default setting for all options is provided
in the Programming Work Sheets as well as page
reference numbers, chart reference numbers and the
programming ‘HOTKEYS’ for the option to allow quick
programming.
Complete the Programming Work Sheets located in
Book 2. Having this information prepared before
programming the panel will speed up the process
considerably.
All information for the 16 zones on the main panel may
be entered in the Programming Work Sheets.
Any zone expanders on the system will include a similar
sheet and the information should be completed for these
as well.
There is no set order in which the panel must be
programmed, however, if you use the following guideline
it may simplify the programming of the panel for the first
time.
