Description
The OE332-23-GBDX General Broadcast Device
Controller provides a method of connecting up to
a maximum of (6) Thermistor 10 K Ohm Room
Temperature Sensors (OE210, OE211, OE212,
and OE213) 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) CO
2
Sensors—4-20 ma
(OE255 and OE256) and/or 0-5VDC (by oth-
ers)— 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 proportional voltage output signal on Ana-
log 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 ad-
justable minimum setting to an adjustable maxi-
mum level. Also, if desired, Analog Output #2
can provide a 10.0 VDC fixed output signal
whenever the CO
2
is above the minimum set-
point. In addition, Relay Output #1 activates
whenever the CO
2
rises above the minimum set-
point and deactivates when it falls 5 PPM below
the minimum setpoint. Relay Output #2 activates
whenever the CO
2
rises above the maximum
setpoint and deactivates when it falls 5 PPM
below the maximum setpoint.
When more than (6) CO
2
or Temperature Sen-
sors are to be used, a second GBD-X controller
can be connected to the VCM-X 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 controller. When both are required at least
(2) GBD-X controllers, one configured for CO
2
control and the other configured for Temperature averaging must be used. Up
to a combined (16) additional GBD-X controllers can be daisy-chained together for a total of (18) GBD-X controllers on one
loop. 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 or the System Manager Touch Screen 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 en-
closure. It is recommended that the GBD-X be mounted in a control enclosure in the building equipment room.
