INTRODUCTION
The communicating device transponder (CDT) is a 2120 system component that is connected to the BMUX via
a 2120 communications channel (see Figure 1).
El
ET
A 2120 System with CDT
FIGURE 1
The CDT mounts in a 2-, 4-, or 6-unit backbox (see Figure 2). Each CDT has two transponder addresses used
to identify its location in the 2120 system (you only select the lower address via switches). Each CDT also has
monitor and control points.

The 2120 CDT allows use of addressable devices to provide individual reporting. So, if an addressable smoke
detector senses smoke, its activation will result in a report that specifically identifies the location of that detector.
Look at Figure 3. You can see that all addressable devices are connected to the CDT panel via a twisted, shielded
wire pair called MAPNET II@.
PS = Addressable Pull Station
ASD = Addressable Smoke Detector
IAM = Interface Addressable Module
ZAM = Zone Addressable Module
Up to 128 Devices Per MAPNET II@
MAPNET II@Block Diagram
FIGURE 3
As Figure 3 shows, there are four basic types of addressable devices:
l Addressable smoke detectors (ASDs), requiring only the MAPNET II@wire pair for both data and power.
l Addressable pull stations (APSs), requiring only the MAPNET II@wire pair for both data and power.
l lnferface addressable modules (IAMs), requiring only the MAPNET II@wire pair for both data and power.
IAMs interface a single conventional device - such as a pull station or smoke detector - to a CDT.
l Zone addressable modules (ZAMs), requiring the MAPNET II@wire pair for data, a pair for power and a
pair to connect the external monitor or control device wiring. A monitor ZAM interfaces a zone of
conventional alarm-initiating devices to the CDT. A control ZAM interfaces a single controlled device to
the CDT. A signal ZAM interfaces a zone of indicating devices to the CDT (signal ZAMs may require a
fourth wire pair for audio or phone riser input).
Since addressable devices have unique locations, each device’s address must be proper/y set. The address for
each device on a MAPNET II@MUST be set when you install the device.
This technical reference provides installation instructions for the CDT panel. Instructions for setting panel and device
switch settings are provided in this document.

CDT PANEL INSTALLATION
The CDT panel is shipped with cabinet drawings for use during installation. Information on reading cabinet drawings
can be found in the 2120 Multiplex System Installation manual (MUX2-21-003).
DOCUMENTS YOU WILL NEED DURING THE INSTALLATION
l System interconnect drawings for the communications channels, any audio and telephone risers, and all
powering.
~ l CDT equipment cabinet drawings showing component locations and external connections.
l M-2120~CDT wiring diagrams.
Note: CDT cabinet drawings refer you to M-2120-CDT wiring diagrams. These wiring diagrams:
l Tell you how the MAPNET II@and power line (if required) are connected to addressable devices.
AND
l Tell you how conventional devices are connected to ZAMs and IAMs.
Consult your Simplex Representative if you do not receive the proper system documentation.
INSTALLATION PRECAUTIONS
A. Use twisted, shielded pair for all MAPNET II@lines.
B. Each CDT equipment cabinet should be connected to building ground via a single, unbroken conductor
(12AWG wire, typical). Conduit ground is not sufficient.
C. MAKE NO CONNECTIONS TO CDTs WITH POWER APPLIED.
D. Before applying power to CDT equipment:
l Verify that power connections have been terminated at the proper terminals.
l Verify that all wiring is free of grounds.
E. Apply power to equipment ONLY in the presence of a qualified Simplex Technical Representative (TR) and
in the following sequence:
l Apply AC power first.
l Apply battery power last.
F. NEVER APPLY OR DISCONNECT CDT EQUIPMENT POWER BY USING AN INTERCONNECT PLUG.

INSTALLATION SUMMARY
The following is a set of recommended procedures to follow during CDT installation. Before you begin wiring:
l Ensure that all system interconnection and wiring diagrams for your system are provided.
l All backboxes (cabinets) and the associated equipment should be properly installed and grounded via
a single, unbroken conductor (12AWG, typical). Conduit ground is NOT sufficient.
Mounting
1. Install the CDT’s backbox using the information in the section entitled “Backboxes” in the 2120 Multiplex
System Installation manual. Use the transponder number on the CDT equipment shipping carton to help you
find the cabinet’s proper location.
2. Install the CDT (and other equipment, if applicable) into the backbox.
Data and Power Connections
3. Connect the 2120 communications channel to the CDT (Figure 4). Use the system data interconnect drawing
and the appropriate CDT cabinet drawing to determine proper connections.

CDT PANEL JUMPER PLACEMENT AND
SWITCH SETTINGS
The CDT panel (Figure 6) contains three switch packages (SW1 through SW3), a pushbutton switch (SW4) that
resets the CDT’s microprocessor when pressed, and six jumpers (JWl through JW6).
JUMPERS JUMPERS
CDT Panel Jumper and Switch Locations

SW1 is used to set the CDT’s transponder address and communications baud rate. Set switches SWl-1 and
SW1 -2 as follows:
BAUD RATE SWl-1 SWl-2
9600 OFF OFF
4800 ON ON
2400 OFF ON
1200 ON OFF
Switches SW1 -3 through SW1 -8 specify the transponder address (one less than the transponder number).

‘SW2 is used to tell the CDT how many monitor points are present (from zero to 128 possible monitor devices).
Switches SW3-1 through SW3-7 are used to tell the CDT how many control points are present (from zero to 64
possible control devices).
Switch SW3-8 is used to indicate whether the MAPNET II@is single line or McCulloh loop. Set SW3-8 ONto indicate
McCulloh loop; set SW3-8 OFF to indicate single line.
CAUTION: At least one switch on either SW2 or SW3 must be OFF or the CDT panel will not operate.
Jumpers JWl through JW6 are set as indicated below.
JW7 and JWZ are IN, and are not normally field-alterable.
JW3 is IN for local mode operation.
JW4 is OUT, and is not normally field-alterable.
JW5 is IN when 2120 communications occur via RS232C interface, and OUT for normal communications.
JW6 is OUT when 2120 communications occur via RS232C interface and IN for normal communications.

The addresses for all CDT monitor devices are set in the same way.
The addresses for all CDT control devices are set in the same way.
Note: Control ZAM Addressing begins with device number 128 and ends with device number 65 (64 possible
control devices per CDT panel). This numbering scheme exists because of the way in which the CDT panel’s
internal memory is laid out. Thus, the first control device on a MAPNET II@ - as far as addressing is
concerned - will “occupy” the 128th position in CDT memory, the second control device will “occupy” the
727th position in CDT memory, etc.
If you look at Figure 7 below, you can see that monitor point addressing begins at the “bottom” of CDT
memory, while control point addressing begins at the “top” of CDT memory.

14. Leave the power applied to this power supply and proceed to the next CDT.
15. (New 2120 installations only) Once you have checked out all CDTs in the system and all other 2120 equipment,
perform the BMUX checkout procedures in the 2120 Multiplex System Checkout Procedures manual (MUX2-
21-004).
Note: When you finally power-up the BMUX, each CDT that comes up will report a LOCAL LOOP COMM FAIL
error message. Ignore the message for the time being; it will clear once the CDT’s MAPNET II@lines are
installed.
15. When you have completed preliminary checkout of all CDTs, remove power from them in the following
sequence:
l Disconnect batteries first.
l Disconnect AC last.
CDT FINAL CHECKOUT
CAUTION: NOTIFY BUILDING PERSONNEL AND APPROPRIATE AUTHORITIES (FIRE AND POLlCf
DEPARTMENTS, ETC.) BEFORE PROCEEDING.
A. Identification of Contractor Wiring Errors
1. Before the contractor applies power to any CDTs, verify that the MAPNET II@communications lines are properly
terminated on each CDT using Figure A or B as appropriate from the M-2120-CDT wiring diagrams, or by using
Figures 12 and 13.
2. The contractor should now apply power to each system component by:
l Applying AC power first.
l Connecting batteries last.
3. (New 2120 installations only) Allow two minutes for the BMUX to initialize.
Note 1: You will need the CMS file covering each CDT to locate devices reported in Step 4.
Note 2: Each CDT uses two transponder addresses; addressable devices are reported on either of the CDT
addresses.
4. Identify all CDT monitor and control device troubles. Remember: The BMUX reports CDT device troubles per
addressable device, so the ‘CDT trouble reports you receive will refer directly to specific MAPNET II@devices.
Use the first three digits of the device’s point number to determine the location of the associated CDT panel.
Note: If you get either a LOCAL LOOP COMM FAIL or LOCAL LOOP MCCULLOH trouble report from a CDT, then
the MAPNET II@lines associated with the reported CDT are disconnected from the panel, their polarity is
reversed, or fuse Fl on the CDT panel is open.
5. If there is a string of devices on the same MAPNET II@that has troubles, look for:
0 Open wiring at a branch circuit junction box.
l Open wiring in the branch circuit itself.
l MAPNET II@wire pairs reversed at a branch circuit junction box.
13
Technical Manuals Online! - http://www.tech-man.com
firealarmresources.com

6. Locate other troubled devices and:
l Check device addressing using the CMS file.
l Check device wiring.
If the wiring and~address check out properly, replace the troubled device.
Note: If two or more devices have the same address setting, then there will be one or more troubles associated
with the devices which have duplicate switch settings. Use half-splitting to isolate the improperly
addressed devices.
B. CDT Functional Checkout
Activate all CDT peripherals and verify that the proper reports are received at the BMUX. Use SMPL operating
commands to operate CDT control or signal ZAMs. If DEVICES DO NOT REPORT, CHECK SW2 AND SW3
SETTINGS ON CDT PANEL.
