DX2010 Installation Instructions
Another mounting option for the DX2010 is a D203 Enclosure. See
Figure 3.
Install the module
in the D20 Enclosure.

Wiring
Remove all power to the system (AC and standby
battery) before making or breaking any
connections. Failure to do so might result in
personal injury and/or damage to the equipment.
4.1 Data Bus Connections
Connect the DX2010 to the control/communicator data and auxiliary
power sources. The DX2010 can be powered directly from the
data bus (see Figure 4).

If using an external 12 VDC power supply, wire as shown in
Figure 5.
When using any external power supply, the negative
(-) output must not be tied to earth ground. A ground
fault condition will be reported if negative (-) is
grounded.

* Wire length may be restricted by panel limitations. See the panel’s
Installation Guide for more information.
** If the DX2010 is powered directly by an external auxiliary power
supply (Figure 5), use the wire lengths specified in the first row
of Table 1.
4.2 Auxiliary Output Connections
The DX2010 has the capacity to provide 12 VDC at up to 100 mA
from the Auxiliary Output (+) OUT (-) terminals to power external
devices such as motion detectors (see Figure 6).
If a trouble condition occurs on the DX2010 (such as an overcurrent
condition), it sends a data bus trouble message to the panel.
When using the auxiliary output on the DX2010, the
maximum distance between the control/
communicator and the module must be limited to
250 ft. (76 m) using #18 AWG (1.2 mm) wire or
100 ft. (30 m) using #22 AWG (0.8 mm) wire. The
maximum distance from the DX2010 output
terminals and the external devices (PIRs, smoke
detectors, etc.) must be limited to 50 ft. (15 m) for
#22 AWG (0.8 mm) or 100 ft. (30 m) for #18 AWG
(1.2 mm) wire.
