Firemen do it against a clock tower

As I was walking through Station Square in Oban this morning a fire engine pulled up and three burly fireman jumped out. Thinking there might be something of interest going on I followed them, but they were simply checking the  defibrillator which sits in a box attached to the clock tower. 

After they'd gone I had a look - if you need to use it you have to dial 999 and somebody will come and open the box.
