About this interactive
Alarm systems are standard in most buildings, and most companies have more than one.
One is for unauthorized entry: door and window contacts, glass-break sensors and motion sensors that report someone getting in where they should not.
One is the fire system: smoke, heat and flame detectors and the manual pull stations.
And there are others for the building's environment, such as moisture getting where it should not, humidity and temperature, so that people are alerted before the equipment is harmed.
To sort a card, ask what the sensor has found: a person, a fire, or a change in the room's conditions.
