INTRODUCTION

Technical Manuals Online! - http://www.tech-man.com

The communicating device transponder (CDT) is a 2120 system component that is connected to the BMUX via a 2120 communications channel (see Figure 1).

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.

A Communicating Device Transponder

FIGURE 2

Page 6

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:

Addressable smoke detectors (ASDs), requiring only the MAPNET II@ wire pair for both data and power.

Addressable pull stations (APSs), requiring only the MAPNET II@ wire pair for both data and power.

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.

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.

manual (MUX2-21-003).

Note:

CDT cabinet drawings refer you to M-2120-CDT wiring diagrams. These wiring diagrams:

Tell you how the MAPNET II@ and power line (if required) are connected to addressable devices.

AND

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:

Verify that power connections have been terminated at the proper terminals.

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:

Apply AC power first.

Apply battery power last.

F. NEVER APPLY OR DISCONNECT CDT EQUIPMENT POWER BY USING AN INTERCONNECT PLUG.

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:

Jumpers JWl through JW6 are set as indicated below.

At least one switch on either SW2 or SW3 must be OFF or the CDT panel will not operate.

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.

Technical Manuals Online! - http://www.tech-man.com

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 (MUX221-004).

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:

Disconnect batteries first.

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:

Applying AC power first.

Connecting batteries last.

3. (New 2120 installations only) Allow two minutes for the BMUX to initialize.

Note 1:

Note

You will need the CMS file covering each CDT to locate devices reported in Step 4.

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.

Open wiring in the branch circuit itself.

MAPNET II@ wire pairs reversed at a branch circuit junction box.

Technical Manuals Online! - http://www.tech-man.com

Page 18

6. Locate other troubled devices and:

Check device addressing using the CMS file.

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.
