The black triangle bell box is the high security bell box it as two covers and extra anti tampers switch’s on 

They were designed so if they were drilled, once the drill bit shorted the two covers it caused a tamper alarm. I got called out to a bank one horrible winters night to a tamper fault on the bell box which you could hardly see because of the snow. I asked the assistant manager if he hand a sweeping brush. He thought i was going to clear the snow on the path for my ladders. Should have seen his face when i twatted the delta bell with the brush loosening all the snow that had blown in the vent causing high resistance.

iirc the high security Rapier had a gel covered anti drill panel across the front of it.
