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.

1.3 System Organization

The manual is broken down into eight areas of discussion for the Det-8Z Transmitter.

They are:

•Introduction

•Definitions

•System Description

•Installation.

•Setup

•Operation

•Testing

•Maintenance

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.
