2.5 Engineering Specifications

Zero Two System - Each system shall
utilize modules capable of monitoring gas
sensing elements or a 0 to 21.7mA analog
signal from gas
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 Warn, A2 Alarm,
Fault Alarm, Master Reset, Master Accept,
Unaccept, CAL, +24Vdc and 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,
Monitors, Galway, Ireland.
TA402A Trip Amplifier Module - The trip
amplifier module, with a General Monitors'
flame detector, shall meet the design
requirements of CSA and Factory Mutual.
The trip amplifier 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 setup mode indicator and a 2
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.
