The following Sections provide a thorough description of how to
wire and configure devices and zones.
2.1 Installation Steps
The following steps are provided to assist you with installing
the panel. We suggest that you read this section in its entirity
before you begin. Once you have an overall understanding of
the installation process, carefully work through each step.
Working in this manner will reduce the number of problems as
well as the amount of time required for a complete installation.
Step 1 Create a Layout
Draw a rough sketch of the building to get an idea of where
all alarm detection devices, keypads and other modules
are to be located.
Step 2 Mounting the Panel
Locate the panel in a dry area close to an unswitched AC
power source and the incoming telephone line. Before
attaching the cabinet to the wall, be sure to press the four
circuit board mounting studs into the cabinet from the back.
After you have attached the cabinet to the wall, stick the
provided DSC logo sticker on the front of the cabinet.
You must complete all wiring before applying AC or
connecting the battery to the panel.
Step 3 Wiring the KEYBUS (Section 2.3)
Wire the KEYBUS to each of the modules following the
guidelines provided in Section 2.3 of this manual.
Step 4 Zone Wiring (Section 2.8)
You must power down the control panel to complete all
zone wiring. Please refer to Section 2.8 when connecting
zones using normally closed loops, single EOL resistors,
double EOL resistors, Fire zones and Keyswitch Arming
zones.
Step 5 Complete Wiring (Section 2.2)
Complete all other wiring including bells or sirens, phone
line connections, and ground connections following the
guidelines provided in Section 2.2 ("Terminal
Descriptions").
Step 6 Power up the Control
Once all zone and KEYBUS wiring is complete, power up
the control panel.
The panel will not power up on the battery connec-
tion alone.
Step 7 Keypad Assignment (Section 2.5)
In order for keypads to be properly supervised, each must
be assigned to a different slot. Please follow the guidelines
provided in Section 2.5 when assigning keypads.
Step 8 Supervision (Section 2.6)
The supervision of every module by the panel is
automatically enabled upon power up. Please verify that
all modules appear on the system according to the
instructions in Section 2.6.
Step 9 Programming the System (Sections 4 and 5)
Section 4 explains how to program the panel. Section 5
contains a complete description of the various
programmable features, which options are available and
how they function. The Programming Worksheets (pages
25-33) should be filled out completely before attempting
to program the system.

Step 10 Testing the System
The panel must be thoroughly tested to ensure that all
features and functions are operating as programmed.
2.2 Terminal Descriptions
AC Terminals – AC (50Hz)
The panel requires a 16.5 volt, 40 VA transformer. Connect
the transformer to an unswitched AC source and connect
the transformer to these terminals.
Do not connect the transformer until all other wiring
is complete.
The panel must have a power line frequency of
50Hz.
Battery Connection
A 12V 4Ah rechargable gel-cell battery is used as a back up
source of power in the event of an AC power failure. The
battery also provides additional current when the panel's
demands exceed the power output of the transformer, such
as when the panel is in alarm.
Do not connect the battery until all other wiring is
complete.
Connect the RED battery lead to the positive battery terminal;
connect the BLACK lead to negative.
Auxiliary Power Terminals – AUX+ and AUX-
These terminals provide up to 550 mA of additional current
at 12 V
for devices requiring power. Connect the positive
DC
side of any device requiring power to the AUX+ terminal, the
negative side to AUX- (ground). The AUX output is protected.
This means that if too much current is drawn from these
terminals (such as a wiring short), the panel will temporarily
shut off the output until the problem is corrected.
Bell Output Terminals – BELL+ and BELL- (Section 3.4)
These terminals provide up to 700 mA of continuous current
at 12 V
for powering bells, sirens, strobes or other warning-
DC
type equipment. Connect the positive side of any alarm
warning device to BELL+, the negative side to BELL–.
Please note that the Bell output is protected: if too much
current is drawn from these terminals (such as a wiring
short), the Bell fuse will open. Three Amps can be drawn for
short periods only.
The Bell output is supervised. If no alarm warning devices
are in use, connect a 1000 ohm resistor across BELL+ and
BELL– to prevent the panel from displaying a trouble
condition. For more information, please refer to Section 3.4
("[ ] [2] Trouble Display").
The bell is programmed by default to terminate after four
minutes. The Bell Cutoff time can be adjusted in
programming section [02] ("System Times").
KEYBUS Terminals – AUX+, AUX-, YEL, GRN (Section 2.3)
The KEYBUS is used by the panel to communicate with
modules and vice versa. Each module has four KEYBUS
terminals that must be connected to the four KEYBUS
terminals on the panel. For more information, see Section
2.3 ("KEYBUS Operation and Wiring").
