OVERVIEW
1.1. General Description
The GDC-350 is an economical, self-contained gas detector for non-hazardous (nonexplosion rated) commercial applications. It is available in two basic configurations:
single-sensor models and dual-sensor models. The sensors can be configured as
one of the following:
•
one on-board (A type)
•
one remote (B type)
•
one on-board and one remote (D type)
•
two on-board (E type)
A basic system provides LEDs to indicate Power, Fail, Low (Warning) Gas Alarm, and
High Gas Alarm. Also included are an integral audible alarm with door-mounted
silence push-button, audible time delay, field-settable relay time delays and two alarm
relays.
Gas-specific electrochemical sensors for toxic gases and oxygen are available, as are
MOS solid state sensors for refrigerants and TVOCs and catalytic sensors for
combustible gases. All GDC-350 on-board sensors are packaged as plug-in “smart”
sensor modules to reduce field maintenance time.
