I can't remember all the details of the Baird 240 line system., but here are some details that come to mind.
The line frequency is 6Kc/s and the frame rate is 25c/s.
The sync pulses were deeper than the 405 system being 50% instead of 30% of the total waveform.
The frame sync was a single broad pulse.
Other details I'll try to find are the duration of the line and frame blanking periods.
