The control system consists of the air lock control unit including monitoring and visualization of room conditions, as well as the decontamination showers and material air locks. The decontamination showers and material air locks as direct interfaces between containment and environment are especially critical points in terms of safety requirements. BRIEM control systems are developed to meet these requirements and are in use in all BSL-4 and many BSL-3 laboratories in Germany. The BRIEM PLC door control system controls the interlocking of doors on both sides within and outside the containment and in the air locks, ensures the maintenance of room pressure levels and prevents cross-contaminations. In case of deviations from the desired value there are serveral forms of alerting and visualization. The alert can be forwarded to you via text message, email to your computer or tablet or by phone.
