They determined that because of the fire's magnitude and location near the top of the building, their mission would be primarily one of rescue. They called for a fifth alarm, which would bring additional engine and ladder companies, as well as for two more elite rescue units.
The most widely used formula for multi-alarm designation is based on the number of units, (for example firetrucks, tankers, rescue vehicles and command vehicles) and firefighters responding to a fire; the more vehicles and firefighters responding, the higher the alarm designation.
2-11 = 4 Engines, 2 Trucks, 1 Tower Ladder, 2 Battalion Chiefs, 1 District Chief, 1 Air.
Every intrusion alarm monitoring system needs a code for arming and disarming. This code, typically four to six digits, must be entered through a keypad. Any person who utilizes one of these systems knows that using and managing these codes is an important part of getting the most out of the system.
Four-alarm Fire
This is an infrequent and catastrophic fire-related event. The incident may involve multiple buildings, hazardous materials, multiple fires, or highly unfavorable weather. At this rank, up to 21 emergency vehicles, both fire and medical, are on the scene with multiple command units.

A two-alarm fire requires assistance from other departments for a couple more pumpers and ladder trucks. Some will go to the scene and the others will cover our stations. A five-alarm fire requires a lot more assistance from the outside due to the large size of the fire.
With contaminants such as dust, insects, grease and nicotine, the smoke alarm chamber is susceptible to becoming excessively sensitive or insensitive. This may lead to either an increase in nuisance false alarms, or to eventually becoming unable to detect smoke.
In some cases, high concentrations of vapour may trigger an alarm, especially if the detector is highly sensitive, but this vapour detection will not be consistent. Lower concentrations of vapour produced by less powerful vaping devices may not trigger an alarm on the same smoke detector.
Your alarm manufacturer may have included a blinking red light to let you know it's time to test the alarm again. The Batteries are Low: Usually accompanied by a loud beep, a blinking red light could mean the batteries in the unit are low. Consider adding fresh batteries and running a test to make sure it's working.
Modern fire alarm systems with addressable intelligence can identify where the fire started. This information helps firefighters respond to the fire without having to search for it, saving precious seconds and maximizing their efforts.
5 Alarm Fire
This is usually the highest level alarm sounded for a fire. There are some fire departments with higher levels, but the general consensus is that a 5 alarm fire is the most dangerous. These types of fires can require as many as 100 firefighters in order to extinguish the fire entirely.

A strike team consists of five of the same type of engine, either Type 1 fire engines to provide structure protection or Type 3 brush engines to assist with fire suppression in rugged terrain. In both cases, each engine comes from a different agency to minimize strain on resources.
The master code on the system is the primary code. It arms and disarms the alarm. Using the master code, you can add users to the system, delete old codes and update the system functions.
You may be wondering, "what is a trouble alarm". A "trouble" fire alarm code means there's a problem that needs fixing, but it's not an emergency.
