SENTINEL™ Breath Alcohol Screening Entry System

SENTINEL Screening Entry System
Request Quote Button

The SENTINEL alcohol screening system enables high-volume "zero tolerance" screening of employees, contractors and visitors in safety sensitive industries such as Mining, Construction and Oil and Gas. The SENTINEL can significantly reduce industrial accidents linked to alcohol consumption.

The SENTINEL entry-point breath alcohol testing system is fast, totally automated and completely non-invasive. Tests are triggered automatically when the subject blows. No mouthpieces or straws are required. The SENTINEL uses internationally recognizable color icons to prompt subjects to blow and to display test results. There are no buttons to push or lights to interpret.

Like its predecessor, the SENTINEL Vehicular Access or SENTINEL-VA is a non-invasive system, and 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.

Unlike other devices, screening results are delivered virtually instantaneously. Negative test results are delivered in less than 2 seconds ensuring access points do not become backed-up. Positive alcohol results are delivered in less than 10 seconds.

The SENTINEL and SENTINEL-VA can be used stand-alone or be sequenced with existing turnstiles, time clocks and other access control systems. Calibration can be done quickly and easily without having to remove the unit or take it out of service. The modular design allows for easy on-site service by your maintenance personnel. Side-access to key components permits easy component replacement and remote software updates using the internal USB access.

The SENTINEL was designed for industrial conditions. Additional measures are included to thwart tampering. Lifeloc’s field-proven, alcohol specific fuel cell sensing technology ensures a long working life.
