1 Introduction
1.1 Purpose
The purpose of this manual is to inform the user on how to install, test, operate, and
maintain a Det-8Z Transmitter.
Although the primary subject of this manual will be the Det-8Z Transmitter, the manual
will also provide information on the System 3505 head end, Form Four 100 mA. Power
Supplies, and the Qmux Qnode Controller.
1.2 Scope
This document is intended as an introduction and tutorial on the installation and
operation of a Det-8Z Transmitter. The Det-8Z Transmitter was designed to monitor
pull ropes and push button switches installed in the Metro North Park Avenue Tunnel. In
case of emergency, the Det-8Z would be activated with the pull rope or push button and
transmit a telegraph code to the decode racks in order to shut down power to the third
rails during the evacuation.
This manual assumes the reader has a background in electronics. Furthermore, this
manual assumes the reader is familiar with 100 ma. City Telegraph loops, Telegraph
transmitters, RS-485 communications, Qmux components, and the Digitize System
3505.

2 Definitions
Chapter 2, Common Definitions for terms used with the Det-8Z Transmitters.
100 mA Loop:
Also known as the municipal loop or city loop. This is the wire that runs in and out
of the telegraph boxes and carries the telegraph code. Voltages on these loops
can range from just a few volts to as much as 140 volts dc. Power supplies at the
head end are programmed to maintain 100 mA on the loop, and do so by varying
the voltage on the lines.
Box Round
Is one complete transmission of the box number plus any additional codes.
Bulldog or Bulldogging the Line
A box is said to be “bulldogging” when it transmits on the loop that already has
another box transmitting on it. When a zone on a panel is tripped the panel looks
to the loop to see if any other boxes are currently transmitting. If another box is
currently transmitting, it will wait for a preprogrammed time period after which it
will bulldog the loop and transmit over the other box.
It was a feature of the older windup boxes that needed to transmit within a certain
period after the hook was pulled or risk winding down without sending the alarm.
Form Four
Power supply cards designed to power telegraph loops.
Ground Mode
This is a backup method for transmitting an Alarm when an open loop condition
exists. If a telegraph transmitter needs to make a transmission and detects an
“Open Loop” condition, it will then switch to Ground Mode in an attempt to get the
transmission through. At the same time, when an Open Loop condition occurs,
the Form Four cards at the head end detect the open and apply a positive
voltage to both sides of the loop and references earth ground as the negative
side of the loop. The telegraph box sends the transmission coding the loop to
earth ground.
Open Loop
Current must flow through the loop at all times in order to transmit an alarm. Any
break in the loop stops the flow of current, creating an “Open Loop”. When an

Describing the System Digitize Inc
2-2 700295-0001 Rev. B 10/21
Open Loop occurs, the Form Four card will detect the absence of current flow
and enter “Ground Mode”.
PNIS (Positive Non-Interfering Successive)
Each box on a telegraph loop monitors the telegraph for coding activity and waits
for a “quiet” before proceeding to send its telegraph transmission.
Preemption
Where a zone of a higher status or priority interrupts the current telegraph
transmission of a zone of lesser status or priority. The zone which has been
interrupted is reinstalled on the queue awaiting transmission.
Transmission Speed
The speed at which a telegraph transmitter sends its transmission. The
transmission speed is the time it will take for one opening and closing of the 100
mA line. The speed generally ranges from 1/8 second to 4 seconds.

3 Describing the System
Chapter 3, Describing the System will explain what a Det-8Z Transmitter is, how it is
connected, setup, and what type of information it reports.
3.1 Description of Det-8Z Transmitter
The Det-8Z Transmitter was designed to monitor pull ropes and push button switches
installed in the Metro North Park Avenue Tunnel. In case of emergency, the Det-8Z
would be activated with the pull rope or push button and transmit a telegraph code to the
System 3505 Decoders. The System 3505 then sends a signal to the MNR SCADA
system in order to shut down power to the third rails during emergencies.

Figure 3-2, Inside Det-8Z Enclosure
The Det-8Z Transmitter is housed in a 24” high x 10.62”wide x 5.5” deep Nema 4x
Stainless Steel enclosure. A door lock is mounted to the door. A hasp is provided to
allow installation of an optional lock. There are four hold-down tabs that keep the door
closed. The enclosure houses the wiring harness, micro controller pcb, and the magnetic
pickup inputs for the Pull ropes.
The pull ropes are connected to either side of the Det-8Z enclosure. Pulling on either
rope moves a magnet inside the enclosure to activate the Det-8Z transmitter. The push
button switch is mounted to the front door of the Det-8Z panel.

What is QMux? Digitize Inc.
700295-0001 Rev. B 10/21 3-3
The core of the Det-8Z is the microcontroller based printed circuit board, which contains
all of the electronics of the panel. The Det-8Z is powered from an uninterrupted 24 vdc
supplied provided from the Substation.
Although all of the settings for the Det-8Z are programmed at the factory, the user can
modify the settings using a Windows based program and connecting the USB port on
the transmitter. See Section 6 for more information on the Det-8Z Programming Utility.
The box number for the Det-8Z transmitter is set using three bcd rotary switches on the
front of the transmitter printed circuit board.
The Det-8Z transmitter can monitor each of the two neighboring transmitters (to the right
and left) and transmit a special trouble code if the either of those panels fail.
Figure 3-3, Typical Det-8Z Transmitter Configuration
A Qnode controller is mounted to each of the Det-8Z transmitter. The Qnode is provided
for future system expansion. The addressable devices are not included as part of this
contract. The Q-Node drives the TBUSSTM, and communicates with up to 99
addressable I/O devices (total) located external to the panel via the TBUSS. The Q-
Node Panel is a microprocessor based central polling controller Buss interface. The
Qnode reports the status to a System 3505 via the TBUSS. It communicates with the
master controller, such as a System 3505 through RS-485 serial port communication. It
is powered by the Det-8Z transmitter.

5 Setting up the System
Chapter 5, Setup will explain how to configure the options on the Det-8Z Transmitter.
The setup for the Det-8Z is quite simple. Most of the options are preset at the factory
and should not be modified.
The options that will need to be set for each transmitter are:
1. The Transmitter Box number.
2. Supervisory Jumpers
3. Qnode Number
5.1 Det-8Z Configuration
The Det-8Z Transmitter is made up two circuit boards:
the Main Controller Board, and
the Qnode controller Board.
Main Controller Board
The function of the main controller board is to monitor the three Alarm inputs (two pull
ropes and the on board push button), and when activated, send a telegraph code to the
station monitoring equipment to signal a emergency third rail power shutdown as well as
identify where the shutdown request originated. The controller can also monitors the
transmitters to the right and left and report a trouble condition if they stop operating.
Although all of the settings for the Det-8Z are programmed at the factory, the user can
modify the settings using a Windows based program and connecting the USB port on
the transmitter. See Section 6 for more information on the Det-8Z Programming Utility.

Figure 5-1, Det-8Z Main Controller Board
Qnode Controller Board
The Q-Node is a microprocessor based central polling controller Buss interface. The Q-
Node drives the Multiplex loop, and communicates with the modules along the TBUSS. It
communicates with the System 3505 through RS-485 serial port communication.
The Q-Node can be set to any address from 1-32. The address is stored internally in an
EEPROM. It is shipped pre-programmed to address #1. The field should reserve
address #1 for use on the last Q-Node.
The Q-Node address is programmed using the Q-Mux Utility Software. See Section 7.

5.2 Setting Transmitter Box Number
Box Number Definition
Each of the Det-8Z transmitters has a separate three digit box number assigned to it.
The first digit of the Box Number represents the Track number, settable from 1 to 4.
The second and third digits of the Box Number represent the Street that the Transmitter
is installed by.
For example: Box Number 157 = Track #1 at 57th street
Box Number 391 = Track 3 at 91st street.
How to set Box Numbers
The Det-8Z Transmitter has three BCD switches for setting the Box Number. See Figure
5-3.
Rotate the center of each BCD switch with a screw driver until the arrow points to the
desired digit. It is suggested to test the new setting out on the transmitter that it has been
set properly.
