Scantronic 9827 system, attack button key required?

Well, I can think of about 6/8 different PA keys.

The Scantronic, or any panel, apart from a wireless panel, has no bearing on the type of PA.

By the way, the Scantronic 9827 is the model of the KeyPad, not your panel which should be a Scantronic 9800
