Description
The OE332-23-GBDX General Broadcast
Device Controller provides a method of
connecting up to a maximum of (6) Room
Temperature Sensors so that they can then
be averaged and globally broadcast to one
VCM-X controller on a local loop. The GBD-
X also includes the ability to read up to (6)
Carbon Dioxide sensors and average or
find the highest reading and then broadcast
the reading to one VCM-X controller on a
local loop. It also provides a 0-10 VDC pro-
portional voltage output signal on Analog
Output #1 of the GBD-X. The GBD-X calcu-
lates and varies this signal depending on
the level of CO
2
in the space as it rises from
an adjustable minimum setting to an adjust-
able maximum level. Also, if desired, Ana-
log Output #2 can provide a 10.0 VDC fixed
output signal whenever the CO
2
is above
the minimum setpoint. In addition, Relay
Output #1 activates whenever the CO
2
rises
above the minimum setpoint and deacti-
vates when it falls 5 PPM below the mini-
mum setpoint. Relay Output #2 activates
whenever the CO
2
rises above the maxi-
mum setpoint and deactivates when it falls
5 PPM below the maximum setpoint.
When more than (6) CO2 or Temperature Sensors are to be used, a second GBD-X controller must be used and
would then allow the use of from (7) to (12) Room Temperature Sensors or CO
2
Sensor inputs. Each GBD-X
controller can be used for either temperature averaging or CO
2
averaging, but not both on the same GBD-X con-
troller. When both are required at least (2) GBD-X controllers, one configured for CO
2
control and the other con-
figured for Temperature averaging must be used. Either a CommLink or MiniLink PD must always be installed on
the controls system when using the GBD-X Controller due to its broadcast requirements. A personal computer
with Prism software installed is also required to program the GBD-X controller.
Mounting
The GBD-X is provided with an integral plastic enclosure which provides mounting points for mounting inside of a
control enclosure. It is recommended that the GBD-X be mounted in a control enclosure in the building equip-
ment room. An optional factory control enclosure for the GBD-X is also available.
