5. Man down alarm
Falling by breathing dangerous gases can cause serious injury and even fatality to workers. If the
Man down alarm function in SAN-11 is set on, SAN-11 can detect falls and send a man down alert
which will activate the audible and visual alarms and alert other people in the area.
The man-down detection uses a three-
axis accelerometer to automatically monitor the user’s
movements in order to identify a sudden fall/impact and a lack of movement for a period of 6
seconds.
Once alert, people can turn off the current man-down alarm by pressing any one of the two buttons.
6. Reset Button
Users can reset the unit by pushing a reset button through a hole on back of shell.
MAINTENANCE
Calibration
The SAN-11 comes pre-calibrated from the factory. However, the O2 sensor should be calibrated
at least once a year, or as described in your company’s safety procedures. You can perform the
calibration yourself, or you can return it to GasLab for factory calibration at a nominal fee. The
temperature and humidity sensors do not require calibration and should remain accurate for the
life of your unit.
Cleaning and Storage
Apply sparingly with a soft cloth and allow drying completely before using. Do not use soap or
Alcohol cleaning. Do not use aromatic hydrocarbons or chlorinated solvents for cleaning.
