This output is provided so that external devices, such as drape pulls, lighting, additional amplifier, etc., can be triggered at the same
time as the B Input is triggered. Just be sure that the triggered device will operate with a 12V DC trigger voltage and does not
demand more than 100 mA of current draw. Actually, the 12V B Status output voltage will drop to about 9V at the max. current
