Spain/Portugal/Gibraltar - Barcelona airport info ?

Can someone who is familiar with the layout of BCN Terminal 2 tell me whether there is one security point for the whole terminal, or separate security points for the A, B, and C sections of the Terminal.

Specifically, if I have boarding pass for a flight (Easyjet) departing T2 - C can I access the airside lounge in T2 - B ?

Thanks very much in advance.

I haven’t used T2 since they opened the new T1, so I’m not sure if all the security checkpoints are still in use. (Apparently T2 feels more like a ghost town these days.)
But, in any case – and what’s important to you, once airside (but before immigration - passport checks) T2 is one common area. So you can without any problem get from T2C to T2B and back, as long as you don't go through immigration.
