3.5.1 Antenna
Selection
GDS Corp offers locally mounted dipole antennas suitable for either Division 1 or Division 2
classified areas
as shown in Figure 3-3 below. Antennas may also be remotely mounted if it is
necessary to raise the height to achieve better RF L.O.S. (Line of Sight).

Sensor Installation (with Smart / Simple Sensor Definition)
Sensors used with the 10-0247 sensor head (see Figure 3-5) are considered “smart” since they
include a memory device that uploads sensor information to the GM ECx anytime a new sensor is
installed. The GM ECx may also accommodate other industry standard “simple” electrochemical
toxic / oxygen sensors, without the memory device, by accepting their wiring into TB2 of the 10-
0232 Display Assembly (see Figure 3-4). The 10-0247’s
Smart Sensor
cable connects to S1 of
the 10-0232 Display Assembly (see Figure 3-4). This unique
Smart Sensor Interface
may be
used to configure smart sensors and / or GM ECX’s from a PC rather than entering all variables
via the magnetic keypad.
