SHIELD™ Lockdown System is a trusted school lockdown system that heightens the safety of students and staff during various threats to your campus. Our system has been crafted through diligent research of past tragedies in U.S. schools and careful collaboration with Law Enforcement Agencies. This process has resulted in the development of a one-of-a-kind patented lockdown system to mitigate against threats to our nation’s educational establishments. Unlike other systems, SHIELD™ was designed as a virtually invisible, daily-use product, to protect lives daily without changing the functionality or appearance of your facility. SHIELD™ is the ONLY system approved by the Georgia State Fire Marshall and written specifically into the State Fire Code
