3.0 Mounting
Failuretofollowtheinstructions in this manual may
result in personal injury and/or damage to the
equipment.
The DX2010 contains static-sensitive components
and must be handled with care. Follow anti-static
procedures when handling the modules.
TestaccordingtoNFPA72if usedinfire applications.
Up to five DX2010 Modules can be installed in the control/
communicator’s enclosure, three on the interior walls and two on
the back wall of the enclosure (see Figures 1 and 2).

4.0 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).

Table 1: Wire Lengths
* 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.

If the DX2010 Module is powered by an external
12 VDC power supply, the output terminals can
supply power for up to 450 ft. (138 m) from the
DX2010 to the remotely powered devices.
If the DX2010's Aux Output ("+Out-" terminals) is
used as an auxiliary power source, the DX2010's R
and B wires must be home-run to either the panel
or to an auxiliary power supply. Do not use a daisy-
chain wire configuration (see Figure 6).

4.3 Tamper Input Connections
Each DX2010 provides an input for tamper devices. The tamper
input monitors external Normally Closed (NC) tamper switches
when wired as shown in Figure 7. The tamper circuit must be
closed to provide proper DX2010 tamper supervision to the control
panel. Do not use an EOL resistor.
The DX2010 also provides an on-board tamper switch for use if
the DX2010 is installed inside the AE20 plastic enclosure. The
cover tamper spring is supplied with the DX2010. The on-board
tamper switch cannot be used if the DX2010 is mounted inside the
control panel’s enclosure (wire the tamper input as shown in
Figure 7 if installed in the control panel’s enclosure).
Use either the tamper input or the on-board tamper switch. Both
cannot be used simultaneously.

4.4 Sensor Loop Connections
The DX2010 has the capacity for both Normally Open (N/O) and
Normally Closed (N/C) contacts. Wire the inputs as shown in
Figure 9.
The DX2010 is not designed for use with two-wire
smoke detectors.
Only use Normally Open (N/O) contacts for fire
applications.

4.5 Tamper Point/Zone Inputs
This feature is not available for some control/communicators.
Consult your control/communicator’s Installation Instructions.
The DX2010 has the capacity for dual tamper point/zone inputs
utilizing two EOL resistors (using 1.5k or 2.2k Alarm Resistor). See
Figure 11.
5.0 DX2010 LED Operation
The DX2010 LED (Figure 12) flashes to indicate the status of the
device. The LED indications are:
• One flash per second indicates normal operation.
• LED steady ON can indicate any of the following:
- G wire is not connected or there is a communications problem
between the control panel and the DX2010.
- No locations/points are assigned to the DX2010 with this
address. See your control/communicator’s programming
guide for location/point assignment instructions.
- Address on the DX2010 is not set correctly.
• LED OFF indicates that there is no power to the module.
6.0 Setting the DX2010’s Address
Use Table 2 to configure the DX2010’s address. Refer to the control/
communicator’s installation manual to determine the appropriate
address for each DX2010 you connect. Figure 13 shows the DIP
switch configuration.
Each time you change the address DIP switches,
cycle the power to the DX2010 (turn the power off
and then on) for the address change to take effect.
