The RIT unit or Rapid Intervention Team includes the Squad Company, one truck, ALS (advanced life support) ambulance, and one Battalion Chief.
The term "Still Alarm" arose during the increase use of telephones for reporting emergencies in modern times compared to pulling a firebox alarm, which is an outdoor device that goes back to invention in 1852. The alarm office's register that received the signals from the actual fireboxes would remain "still" when someone reported a fire or emergency via telephone, therefore all telephone alarms began to be referred to as "Still Alarms".
