6.7 Engineering Specifications

6.7.1 Zero Two System

Each system shall utilize modules capable of monitoring gas-sensing elements, or a 0 to
21.7mA analog signal from gas or flame detection transmitters. The system chassis
shall be available in 4, 8 and 16 channels. Each chassis shall contain a bus for the
following independent signals:

•

A1

Alarm

•

A2

Alarm

•

Fault

•

Master

Reset

•

Master

Accept

•

Unaccept

•

CAL

•

+24Vdc

•

System Common

Module signals shall be capable of being bussed from one chassis to another, so that up
to 100 modules can comprise a single system. The gas and flame detection modules
shall be electrically and physically compatible and capable of being used in the same
chassis to form combined fire and gas detection systems. The system shall consist of
Zero Two Series component modules as manufactured by General Monitors, Lake
Forest California, U.S.A. or General Monitors, Galway, Ireland.

6.7.2 TA102A Control Module

The control module, with sensor, shall meet the performance requirements of CSA 22.2
No. 152-M1984 & FM Classes 6310 & 6320. It shall be capable of monitoring 0 to 100%
LEL concentration of combustible gases/vapors. The control module shall have an
interface panel, providing a mode/select switch and the following indications:

•

2 discrete alarm threshold level indicators

•

a “fault” or “malfunction” indicator

•

a “ready” indicator

•

a calibration mode indicator

•

a setup mode indicator

•

a 2 digit digital display

All alarm parameters and user options shall be software selectable. A power on self-test
(POST) is automatically performed each time the trip amplifier module powers up.
A functional card test and a front panel LED test shall be switch capable without
interrupting normal on-line services.
The control module shall be capable of insertion and removal during power on
conditions without damage to any component module in the system. The control module
will generate display codes associated with fault conditions whenever a fault or
malfunction occurs. A mode/select switch shall provide the operator front panel access
to:

•

a setup check mode

•

a

setup

mode

•

inhibit

mode

.

The control module shall have a password protected setup routine capable of having the
password disabled.
