MODULAR GAS SENSOR BASE ACCEPTS AG SERIES GAS SENSORS
FEATURES
• Modular platform accepts Veris AG Series sensors (sold separately)...
no need to install a new GWN when the sensor life wears out
• Three colored LEDs (red, yellow, green)...easy status viewing
• Microprocessor controlled...excellent stability
• No calibration required...easy maintenance and
worry-free operation
• Interface to DDC system or direct fan control...easy integration with
existing systems
• Interface to control system via 4 to 20 mA with relay, 0 to 5/
0 to 10 Vdc with relay, or relay only options...application exibility
• Relay outputs provide low, high, and sensor end-of-life signals for
multi-stage fan actuation and service indication
DESCRIPTION
GWN Series gas platform oers a convenient means for sensing gases in
the environment. The GWN is mounted to any single-gang electrical box
and wired to the building controller. Then, a single AGxx gas sensor (sold
separately) is installed in the GWN. With this design, there is no need for a
costly new installation when a sensor reaches the end of its life. The GWN
platform remains installed, and the installer simply opens the GWN housing
to replace the modular sensor inside, reducing labor costs and downtime.
AG Series sensors can be swapped in the GWN platform at any time with
minimal eort. The GWN platform converts the signal from the AG sensor
into an analog or relay signal compatible with building control systems.

SPECIFICATIONS
The GWN operates only when an AG Series gas sensor is installed (sold separately).
Accuracy, sensitivity, setpoints, and measurement range are dependant on the AG Series
sensor connected to the GWN platform. See the AG Series sensor installation guide for
details.
* The AG Series gas sensors are warranted for two years from the date of manufacture. The
AG Series sensors are not included in the five-year GWN warranty.
