Warnings

nAll Zero Two Series Modules

contain components which can be

damaged by static electricity.

Special care must be taken when

wiring the system to ensure that

only the connection points are

touched.

nUnitized Flame Detectors

This chapter provides a brief description of

the Model TA402A, its features & benefits

and a list of some of its applications. More

detailed information on the features and

benefits listed in section 1.2 will be

presented in later chapters.

1.1 General Description

The General Monitors Model TA402A (see

figure 1) is a single channel Flame Detection

Trip Amplifier designed for use in Zero Two

Series Gas and Flame Detection Systems.

This Module connects to the wires from a

field mounted General Monitors Flame

Detector, which monitors the presence of

radiation emitted from fires.

The Model TA402A is electrically and

physically compatible with the other gas

detection and system modules in the Zero

Two Series. It is distinguished from the

other modules by its red border and

“TA402A" in the upper right corner of the

front panel. The Model TA402A is

designed for use in non-hazardous

environments.

Figure 1

1.2 Features & Benefits

Microprocessor Based Electronics:

monitors fault conditions, sensor inputs and

provides outputs in the form of display

codes, analog signal, relay contact and open

collector activations.

Setup Mode: allows the user to set

parameters such as alarm output options, test

options, etc. These parameters are viewed

on the display during the Setup Mode.

Password Option: prevents unauthorized

alteration of the setup parameters (can be

disabled).

Setup Check Mode: allows the user to view

the parameters that have been set by the

factory and/or an operator.

LED Test: tests the integrity of each display

LED and each segment of the digital display

on the front panel.

Card Test: tests the functionality of the

card through the microprocessor ramping up

the signal to the alarm level for the time

delay.

Live Insertion/Removal: allows the user to

insert or remove a module while power is

applied to the system without damage to any

of the components in the system.

digit digital display. All Warn and Alarm

parameters and user options shall be

software selectable. A functional card test

and a front panel LED test shall be switch

capable without interrupting normal on-line

services. The trip amplifier module shall be

capable of insertion and removal during

power on conditions without damage to any

component module in the system.
