Safety Controller (LON)

The Safety Controller monitors the status of all the library doors and cuts power to the rail when any door opens unexpectedly.

This card has a battery so that it can report "Door Has Been Opened" status if any door opens while the library has no power.

Safety Controller

  1. Emergency shut off — connects to the customer's emergency power off (EPO) system generally through an external switch (installed by the customer) which cuts power to the library in an emergency.
