The inside enclosure

We recently equipped the baboon enclosure at Wildlands in Amersfoort with a robust Trapped Key Interlock system. This solution is low-threshold, efficient and extremely reliable.

There is always a chance that an animal will escape from its enclosure in the zoo. An escape can lead to dangerous situations. It is possible to prevent an escape from a zoo with a Trapped Key Interlock system from Fortress Interlocks.

The baboon enclosure in the application example below is divided into several areas.

  • The inside enclosure
  • The outside enclosure
  • The baboon arena
  • The lock area

In this application example, three hatches lead from the inside enclosure to the outside enclosure and two hatches lead from the outside enclosure to the baboon arena. The lock room has two doors, door 1 and door 2.

The application works as follows
When someone wants to enter the baboon enclosure, he or she requests access at door 1 by pressing the white button on the safety switch. Door 1 will only open when all five hatches and door 2 are closed. The PLC locks all hatches and door 2.

Then the lock area can be entered and door 1 closed. Then access can be requested at door 2 to enter the outside area by pressing the white button of the safety switch again. Door 2 only opens when all hatches and door 1 are closed. At the same time the PLC locks all hatches and door 1, so that they cannot be opened.

Take the safety key out of the safety switch and take it with you into the outside area, thus preventing entrapment.

In case of an emergency the room can be left by pressing the emergency release on door 1. Pressing the blue push buttons resets the safety switches.

When leaving the room, the previous steps must be carried out in reverse order.
