NCS Sub-brand Icons

As part of the NCS branding project, I have to develop icons for their various sub-brands and functions - Nurse Call (primary), Security and Data (secondary).

Here's where I could use some constructive input. I'm struggling with the Data one (bottom right). It needs to be kept simple, sit within the 'alert call' markings, and somehow link with the others.

Thoughts?

Take a look at the attached file to see them with wording.
