Section 2: Installation and Wiring

The following sections provide a complete description of how to wire and configure devices and zones.

2.1 Installation Steps

The following steps are provided to assist with the instal-
lation of the panel. It is suggested that you read over this
section briefly to get an overall understanding of the
order of installation. Once this is done carefully work
through each step. Working from this plan will help
reduce problems and reduce the overall installation time
required.
Step 1 Create a Layout
Draw a rough sketch of the building and include all alarm
detection devices, zone expanders, keypads and all other
modules that are required.
Step 2 Mounting the Panel
Locate the panel in a dry area, preferably located near an
unswitched AC power source and the incoming tele-
phone line. Before attaching the cabinet to the wall be
sure to press the five circuit board mounting studs into
the cabinet from the back.
NOTE: Complete all wiring before applying AC or con-
necting the battery.
Step 3 Wiring the Keybus (Section 2.4)
Wire the Keybus to each of the modules following the
guidelines provided.
Step 4 Assigning Zones to Zone Expanders
(Section 2.6)
If zone expander modules are being used the modules
must be configured so the panel knows which zones are
assigned to each expander. Follow the guideline provided
to assign zones to expanders.
Step 5 Zone Wiring (Section 2.10)
Power down the control panel and complete all zone wir-
ing. Follow the guidelines provided in section 2.10 to con-
nect zones using normally closed loops, single EOL
resistor, double EOL resistors, Fire zones and Keyswitch
Arming zones.
Step 6 Completing Wiring
Complete all other wiring including bells or sirens, tele-
phone line connections, ground connections or any other
wiring necessary. Follow the guidelines provided in sec-
tion 2.2 'Terminal Descriptions'.
Step 7 Power up the Control Panel
Once all zone wiring and Keybus wiring is complete,
power up the control panel.
NOTE: The panel will not power up if only the battery
is connected.
Step 8 Keypad Assignment (Section 2.7)
Keypads must be assigned to different slots to be prop-
erly supervised. Follow the guideline provided in section
2.7 to assign keypads.
Step 9 Confirming Module Supervision
(Section 2.8)
By default, all modules are supervised upon installation.
Supervision is enabled at all times so that the panel can
indicate a Trouble if a module is removed from the sys-
tem.
To confirm that each module is properly supervised, fol-
low the guidelines provided in section 2.8.
Step 10 Programming the System (Sections 4 & 5)
Section 4.0 provides a complete description of how to pro-
gram the panel. Section 5.0 contains complete descriptions
of the various programmable features, what options are
available and how the options function. The Programming
Worksheets should be filled out completely before attempting
to program the system.
Step 11 Testing the System
Test the panel completely to ensure that all features and
functions are operating as programmed.

2.2 Terminal Descriptions

NOTE: AC Terminals - AC
The panel requires a 16.5 volt, 40 VA transformer. Con-
nect the transformer to an unswitched AC source and
connect the transformer to these terminals.
NOTE: Do not connect the transformer until all other
wiring is complete.
Battery Connection
The battery is used to provide backup power in the event
of an AC power failure and to provide additional current
when the panel demands exceed the power output of the
transformer, such as when the panel is in alarm.
NOTE: Do not connect the battery until all other wir-
ing is complete.
Connect the RED battery lead to the positive of the bat-
tery, the BLACK battery lead to the negative.
Auxiliary Power Terminals - AUX+ and GND
These terminals provide up to 550mA of current at 12
V
(rated 11.6-12.6 V
DC
tions) for devices requiring power. Connect the positive
side of any device requiring power to the AUX+ terminal,
the negative side to GND. The AUX output is protected; if
too much current is drawn from these terminals (wiring
short) the panel will temporarily shut off the output, until
the problem is corrected. NOTE: The maximum AUX
capacity for 24-hr standby is 420mA.
Bell Output Terminals - BELL+ and BELL-
These terminals provide up to 3 Amps of current at 12 V
(with standby battery; 700 mA continuous) for powering
bells, sirens, strobes or other warning type equipment.
Connect the positive side of any alarm warning device to
BELL+, the negative side to BELL–. The BELL output is
protected; if too much current is drawn from these termi-
nals (wiring short) the BELL PTC will open.
The bell output is supervised. If no alarm warning device
is being used connect a 1K
BELL– to prevent the panel from displaying a Trouble con-
dition (see section '[*][2] Trouble Display').
Keybus Terminals - RED, BLK, YEL, GRN
The Keybus is used by the panel to communicate with
modules and by modules to communicate with the panel.
Each module has four Keybus terminals that must be con-
nected to the four Keybus terminals on the panel. For
more information, see section 'Keybus Operation and
Wiring'.
