Installation
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Disconnect and lock out all power supplies before beginning the installation.
2. Choose a location on a wall in the area to be monitored. Install the unit on a standard electrical box centrally, near main traffic
paths but away from outside air vents and excessive drafts.
3. Remove the front cover of the GWN unit, and set it aside.
4. Wiring terminals are located on the back of the unit. Determine whether these terminals fit into the electrical box chosen
for the installation. In the case of some electrical boxes, such as weatherproof style boxes, the GWN may not make a snug fit
against the box. If this happens, use the Veris AA66 Foam Gasket Kit accessory to improve the fit (sold separately).
5. Run wires through the back of the electrical box and wire the GWN as shown.

6. Mount the GWN on the box. Use the two mounting holes on the unit and the included #6 screws. The wiring terminals must
face into the electrical box, with the board facing outward.
7. Install the AGxx Series gas sensor according to the directions included with the sensor.
8. Adjust the selection switches as needed. Set the voltage output switch to either 0-5V or 0-10V if using a voltage output model.
If the AGxx sensor has a selectable low setpoint value, use the setpoint selection switch to choose the higher or lower of the
options. High setpoint values are fixed for all AGxx sensors.
9. If desired, replace the LED light pipes with the black plastic light blocking insert (included with the GWN). The light pipes are
located inside of the front cover.
10. Replace the front cover. Reconnect power.
