(i)Whether an alarm is real or false all the details, from the preliminary whistle of the warder to the conclusion of the search for the missing prisoners or the suppression of the disturbance, as the case may be, should be carried out. To accustom warders to the different circumstances with which they may be called upon to deal and test their preparedness to turn out at short notice, an alarm parade shall be held twice a month at any hour of the day or night without previous warning and started from one of the places where prisoners are usually assembled.
