## Description of the bug
see title

## What's the difference with what should have happened?
I should be able to attach a remote signaller to the wires of an apc, as there is a button to do so.

## How do we reproduce this bug?
Unscrew an apc frame.
Attempt to apply signaller to a wire.
Find that this does not work.
