School Lockdown Systems

In school crisis management, knowledge and time become your most powerful tools. Often, those in charge have very minimal information and yet must make critical decisions in seconds. Having a reliable solution that provides real-time visibility of the situation and the ability to quickly lockdown classrooms can be the difference between chaos or saved lives.

APL Access and Security uses SIELOX CLASS Crisis Lockdown Alert Status System to address the two critical needs of crisis management in one solution. SIELOX CLASS allows administrators to reduce communication time and keep students safe with immediate lockdown procedures.
