Fire Drill - Transmission of Fire Alarm "After Hours"

What is the requirement for fire signal transmissions during fire drills?

Any examples are for illustrative purposes only.  

The Joint Commission standard EC.02.03.03 EP 3 requires transmission of a fire signal during every fire drill requiring the fire alarm to be activated. 

There is an allowance for a coded announcement to replace audible alarms for fire drills conducted between the hours of 9:00 pm and 6:00 am. This allows for only silencing the audible signals not the transmission of the fire alarm signal.
