Lifeloc Sentinel VA Breath Alcohol Screening Entry System

The SENTINEL Vehicular Access or SENTINEL-VA is Lifeloc’s latest innovation in entry-point breath alcohol testing.

Like its predecessor, the SENTINEL-VA is a non-invasive system in which no mouthpieces or straws are needed and is able to be integrated with existing access control systems.




The SENTINEL-VA can be self-administered.

A driver simply pulls up to the access point, takes the breathalyzer off of the cradle, blows into the instrument and is either allowed or denied entry based on the breath alcohol results.
Alternatively, security personnel may hold or pass the breathalyzer to the driver.
The SENTINEL-VA may also be used in place of the original SENTINEL to accommodate those employees who use wheelchairs.
