KWJ-WSN CO
Wireless Carbon Monoxide Sensor
Additional Notes of Operation
Sensor Mounting and Installation Tips
• It is recommended to install sensors in a conspicu-
ous location to facilitate airflow around the sensor.
• Installing sensors near an opening where CO may
be regularly present (garage door, etc.) may cause
readings to periodically spike, and may affect TWA
calculations.
• It is recommended for maximum immediate CO
protection, that the user install a UL approved
commercially available carbon monoxide de-
tector with an audible alarm, or a KWJ Alarm
Module, to work alongside the KWJ-WSN CO
modules.
Setup Considerations
It is recommended that the user install no more than 15
sensor modules per gateway due to wireless bandwidth
limitations if all sensors alarm in response to 400 ppm
simultaneously.
Default Notification Settings
• OSHA (Industrial) setting includes thresholds for 50,
125, and 400 ppm as well as 50 ppm 8-hour TWA.
• Health Level setting includes the OSHA thresholds
as well as TWA thresholds of 9, 13, 16, 25, and 35
ppm.
•
NOTE: Be aware that some user-defined thresholds
may conflict with the default settings. In the case of
a conflict, the default notification will be applied.

CO Safety
While your KWJ-WSN CO sensor is an excellent mea-
sure of protection from CO exposure, it is also recom-
mended that you keep the following in mind if you are
ever away from your dashboard or the device receiving
notifications:
The initial symptoms of CO poisoning are similar
to the flu (but without the fever). They include:
* Headache
* Fatigue
* Shortness of breath
* Nausea
* Dizziness
If you suspect that you are experiencing CO poison-
ing, leave the area and get fresh air immediately.You
could lose consciousness and die if you stay in the
affected area. Get medical attention immediately and
inform medical staff that CO poisoning is suspected.
Call the Fire Department to determine when it is safe
to reenter the area.
