A Montessori school in Essex County NJ called asking for a new locking system for their main front door. It needed to be a grade 1 computerized keyless entry, which conformed to life safety. They also wanted it to work for different staff schedules, and calendar days.
We installed a Kaba E Plex 5300 series electronic lock, matched with an Arrow 1200 panic bar inside. The customer programs it with a wireless infra red controller and an inexpensive net book computer.
