System Wiring - DSC NT9005 V1.0 Installation & Programming Manual

5. Using wall anchors for all screw locations, secure
the back cover to the wall.
2-2.3 Mounting the Control Unit
1. Position the unit on the mounting tabs located at
the top of the back cover. Refer to Figure 5.
WARNING: Ensure that AC Power is OFF when mount-
ing the unit to the back panel. If the header terminals
are inserted into the incorrect terminals on the termi-
nal block, permanent damage to the unit may result.
2. Ensure that the two antennas are not obstructed,
bent or repositioned. Slide tabs on bottom of
unit into the slots of the back cover.
3. Secure unit in place with the two screws pro-
vided.

2-3 System Wiring

The R, B, Y1, G2 terminals located on the inside of
the back cover, can be configured as a Keybus, or 2
hardwired zones or 2 PGMs (programmable outputs),
or 1 PGM and 1 hardwired zone . If configured as a
Keybus or hardwired zone, wire devices using 22
Figure 5
AWG stranded wire; maximum wire run distance
must not exceed 1000 ft. (305 m.).
Example of Keybus Wiring
2-3.1 Keybus Wiring
The Keybus is used to communicate to other modules
on the system. In this configuration the 'R' terminal
is +6V , the B terminal is ground, Y1 terminal is
DC
the CLOCK and the G2 terminal is the DATA. If the
system is configured for Keybus then Keybus Enabled
(section [018] option 1) must be ON. Hardwired
zones 1 and 2, and PGMs 1 and 2 will not be avail-
able. If an NT9204 module is connected to the sys-
tem (via the Keybus) then PGMs 11, 12, 13 and 14
will be available. Enter [00] in section [030] when an
NT9204 is used.
The Keybus can not drive any module other than
the NT9204 directly. To connect to LINKS2x50 or
Skyroute®, an NT9204 module must be connected
to the Keybus.
